致读者

Netkiller 系列手札 已经被 Github 收录，并备份保存在北极地下250米深的代码库中，备份会保留1000年。

Preserving open source software for future generations

The world is powered by open source software. It is a hidden cornerstone of modern civilization, and the shared heritage of all humanity.

The GitHub Arctic Code Vault is a data repository preserved in the Arctic World Archive (AWA), a very-long-term archival facility 250 meters deep in the permafrost of an Arctic mountain.

We are collaborating with the Bodleian Library in Oxford, the Bibliotheca Alexandrina in Egypt, and Stanford Libraries in California to store copies of 17,000 of GitHub’s most popular and most-depended-upon projects—open source’s “greatest hits”—in their archives, in museum-quality cases, to preserve them for future generations.

自述

《Netkiller 系列 手札》是一套免费系列电子书，netkiller 是nickname 从1999 开使用至今，“手札” 是札记，手册的含义。

2003年之前我还是以文章形式在BBS上发表各类技术文章，后来发现文章不够系统，便尝试写长篇技术文章加上章节目录等等。随着内容增加，不断修订，开始发布第一版，第二版......

IT知识变化非常快，而且具有时效性，这样发布非常混乱，经常有读者发现第一版例子已经过时，但他不知道我已经发布第二版。

我便有一种想法，始终维护一个文档，不断更新，使他保持较新的版本不过时。

第一部电子书是《PostgreSQL 实用实例参考》开始我使用 Microsoft Office Word 慢慢随着文档尺寸增加 Word 开始表现出力不从心。

我看到PostgreSQL 中文手册使用SGML编写文档，便开始学习Docbook SGML。使用Docbook写的第一部电子书是《Netkiller Postfix Integrated Solution》这是Netkiller 系列手札的原型。

至于“手札”一词的来历，是因为我爱好摄影，经常去一个台湾摄影网站，名字就叫“摄影家手札”。

由于硬盘损坏数据丢失 《Netkiller Postfix Integrated Solution》 的 SGML文件已经不存在; Docbook SGML存在很多缺陷UTF-8支持不好，转而使用Docbook XML.

目前技术书籍的价格一路飙升，动则￥80，￥100，少则￥50，￥60. 技术书籍有时效性，随着技术的革新或淘汰，大批书记成为废纸垃圾。并且这些书技术内容雷同，相互抄袭，质量越来越差，甚至里面给出的例子错误百出，只能购买影印版，或者翻译的版本。

在这种背景下我便萌生了自己写书的想法，资料主要来源是我的笔记与例子。我并不想出版，只为分享，所有我制作了基于CC License 发行的系列电子书。

本书注重例子，少理论（捞干货），只要你对着例子一步一步操作，就会成功，会让你有成就感并能坚持学下去，因为很多人遇到障碍就会放弃，其实我就是这种人，只要让他看到希望，就能坚持下去。

1. 写给读者

为什么写这篇文章

有很多想法,工作中也用不到所以未能实现，所以想写出来,和大家分享.有一点写一点,写得也不好,只要能看懂就行,就当学习笔记了.

开始零零碎碎写过一些文档，也向维基百科供过稿，但维基经常被ZF封锁，后来发现sf.net可以提供主机存放文档，便做了迁移。并开始了我的写作生涯。

这篇文档是作者20年来对工作的总结,是作者一点一滴的积累起来的，有些笔记已经丢失，所以并不完整。

因为工作太忙整理比较缓慢。目前的工作涉及面比较窄所以新文档比较少。

我现在花在技术上的时间越来越少，兴趣转向摄影，无线电。也想写写摄影方面的心得体会。

写作动力:

曾经在网上看到外国开源界对中国的评价，中国人对开源索取无度，但贡献却微乎其微.这句话一直记在我心中，发誓要为中国开源事业做我仅有的一点微薄贡献

另外写文档也是知识积累，还可以增加在圈内的影响力.

人跟动物的不同,就是人类可以把自己学习的经验教给下一代人.下一代在上一代的基础上再创新,不断积累才有今天.

所以我把自己的经验写出来,可以让经验传承

没有内容的章节:

目前我自己一人维护所有文档，写作时间有限，当我发现一个好主题就会加入到文档中，待我有时间再完善章节，所以你会发现很多章节是空无内容的.

文档目前几乎是流水帐试的写作，维护量很大，先将就着看吧.

我想到哪写到哪,你会发现文章没一个中心,今天这里写点,明天跳过本章写其它的.

文中例子绝对多,对喜欢复制然后粘贴朋友很有用,不用动手写,也省时间.

理论的东西,网上大把,我这里就不写了,需要可以去网上查.

我爱写错别字,还有一些是打错的,如果发现请指正.

文中大部分试验是在Debian/Ubuntu/Redhat AS上完成.

写给读者

至读者：

我不知道什么时候，我不再更新文档或者退出IT行业去从事其他工作，我必须给这些文档找一个归宿，让他能持续更新下去。

我想捐赠给某些基金会继续运转，或者建立一个团队维护它。

我用了20年时间坚持不停地写作，持续更新，才有今天你看到的《Netkiller 手扎》系列文档，在中国能坚持20年，同时没有任何收益的技术类文档，是非常不容易的。

有很多时候想放弃，看到外国读者的支持与国内社区的影响，我坚持了下来。

中国开源事业需要各位参与，不要成为局外人，不要让外国人说：中国对开源索取无度，贡献却微乎其微。

我们参与内核的开发还比较遥远，但是进个人能力，写一些文档还是可能的。

《Netkiller 系列 手札》的作者

成长阶段

1981年1月19日(庚申年腊月十四)出生于黑龙江省青冈县建设乡双富大队第一小队

1989年9岁随父母迁居至黑龙江省伊春市，悲剧的天朝教育，不知道那门子归定，转学必须降一级，我本应该上一年级，但体制让我上学前班，那年多都10岁了

1995年小学毕业，体制规定借读要交3000两银子(我曾想过不升初中)，亲戚单位分楼告别平房，楼里没有地方放东西，把2麻袋书送给我，无意中发现一本电脑书BASIC语言，我竟然看懂了，对于电脑知识追求一发而不可收，后面顶零花钱，压岁钱主要用来买电脑书《MSDOS 6.22》《新编Unix实用大全》《跟我学Foxbase》。。。。。。

1996年第一次接触UNIX操作系统，BSD UNIX, Microsoft Xinux(盖茨亲自写的微软Unix，知道的人不多)

1997年自学Turbo C语言，苦于没有电脑，后来学校建了微机室才第一次使用QBASIC(DOS 6.22 自带命令)，那个年代只能通过软盘拷贝转播，Trubo C编译器始终没有搞到，

1997年第一次上Internet网速只有9600Bps, 当时全国兴起各种信息港域名格式是www.xxxx.info.net, 访问的第一个网站是NASA下载了很多火星探路者拍回的照片，还有“淞沪”sohu的前身

1998~2000年在哈尔滨学习计算机，充足的上机时间，但老师让我们练打字（明伦五笔/WT）打字不超过80个/每分钟还要强化训练，不过这个给我的键盘功夫打了好底。

1999年学校的电脑终于安装了光驱，在一张工具盘上终于找到了Turbo C, Borland C++与Quick Basic编译器，当时对VGA图形编程非常感兴趣，通过INT33中断控制鼠标，使用绘图函数模仿windows界面。还有操作 UCDOS 中文字库，绘制矢量与点阵字体。

2000年沉迷于Windows NT与Back Office各种技术，神马主域控制器，DHCP，WINS，IIS，域名服务器，Exchange邮件服务器，MS Proxy, NetMeeting...以及ASP+MS SQL开发；用56K猫下载了一张LINUX。ISO镜像，安装后我兴奋的24小时没有睡觉。

职业生涯

2001 年来深圳进城打工,成为一名外来务工者. 在一个4人公司做PHP开发，当时PHP的版本是2.0, 开始使用Linux Redhat 6.2.当时很多门户网站都是用FreeBSD,但很难搞到安装盘，在网易社区认识了一个网友,从广州给我寄了一张光盘，FreeBSD 3.2

2002 年我发现不能埋头苦干,还要学会"做人".后辗转广州工作了半年，考了一个Cisco CCNA认证。回到深圳重新开始，在车公庙找到一家工作做Java开发

2003 年这年最惨,公司拖欠工资16000元,打过两次官司2005才付清.

2004 年开始加入分布式计算团队,目前成绩，工作仍然是Java开发并且开始使用PostgreSQL数据库。

2004-10月开始玩户外和摄影

2005-6月成为中国无线电运动协会会员,呼号BG7NYT,进了一部Yaesu FT-60R手台。公司的需要转回PHP与MySQL，相隔几年发现PHP进步很大。在前台展现方面无人能敌，于是便前台使用PHP，后台采用Java开发。

2006 年单身生活了这么多年,终于找到归宿. 工作更多是研究PHP各种框架原理

2007 物价上涨,金融危机，休息了4个月（其实是找不到工作）,关外很难上439.460中继，搞了一台Yaesu FT-7800.

2008 终于找到英文学习方法， 《Netkiller Developer 手札》，《Netkiller Document 手札》

2008-8-8 08:08:08 结婚,后全家迁居湖南省常德市

2009《Netkiller Database 手札》,2009-6-13学车，年底拿到C1驾照

2010 对电子打击乐产生兴趣，计划学习爵士鼓。由于我对Linux热爱，我轻松的接管了公司的运维部，然后开发运维两把抓。我印象最深刻的是公司一次上架10个机柜，我们用买服务器纸箱的钱改善伙食。我将40多台服务器安装BOINC做压力测试，获得了中国第二的名次。

2011 平凡的一年，户外运动停止，电台很少开，中继很少上，摄影主要是拍女儿与家人，年末买了一辆山地车

2012 对油笔画产生了兴趣，活动基本是骑行银湖山绿道，

2013 开始学习民谣吉他，同时对电吉他也极有兴趣；最终都放弃了。这一年深圳开始推数字中继2013-7-6日入手Motorola MOTOTRBO XIR P8668，Netkiller 系列手札从Sourceforge向Github迁移；年底对MYSQL UDF，Engine与PHP扩展开发产生很浓的兴趣，拾起遗忘10+年的C，写了几个mysql扩展（图片处理，fifo管道与ZeroMQ），10月份入Toyota Rezi 2.5V并写了一篇《攻城狮的苦逼选车经历》

2014-9-8 在淘宝上买了一架电钢琴 Casio Privia PX-5S pro 开始陪女儿学习钢琴，由于这家钢琴是合成器电钢，里面有打击乐，我有对键盘鼓产生了兴趣。

2014-10-2号罗浮山两日游，对中国道教文化与音乐产生了兴趣，10月5号用了半天时间学会了简谱。10月8号入Canon 5D Mark III + Canon Speedlite 600EX-RT香港过关被查。

2014-12-20号对乐谱制作产生兴趣（https://github.com/SheetMusic/Piano），给女儿做了几首钢琴伴奏曲，MuseScore制谱然后生成MIDI与WAV文件。

2015-09-01 晚饭后拿起爵士鼓基础教程尝试在Casio Privia PX-5S pro演练，经过反复琢磨加上之前学钢琴的乐理知识，终于在02号晚上，打出了简单的基本节奏，迈出了第一步。

2016 对弓箭（复合弓）产生兴趣，无奈兲朝法律法规不让玩。每周游泳轻松1500米无压力，年底入 xbox one s 和 Yaesu FT-2DR, 同时开始关注功放音响这块

2017 7月9号入 Yamaha RX-V581 功放一台，连接Xbox打游戏爽翻了，入Kindle电子书，计划学习蝶泳，果断放弃运维和开发知识体系转攻区块链。

2018 从溪山美地搬到半岛城邦，丢弃了多年攒下的家底。11 月开始玩 MMDVM，使用 Yaesu FT-7800 发射，连接MMDVM中继板，树莓派，覆盖深圳湾，散步骑车通联两不误。

2019 卖了常德的房子，住了5次院，哮喘反复发作，决定停止电子书更新，兴趣转到知乎，B站

2020 准备找工作

职业生涯路上继续打怪升级

php-fpm

mac下自带的软件

neo@MacBook-Pro ~ % php -v

PHP 5.6.30 (cli) (built: Feb  7 2017 16:18:37)

Copyright (c) 1997-2016 The PHP Group

Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

启动php-fpm方法如下

cd /private/etc

sudo cp php-fpm.conf.default php-fpm.conf

修改error_log项, 改为error_log = /usr/local/var/log/php-fpm.log

启动 php-fpm

1.7. rotate log

log shell

一些特别的情况下需要切割日志，请参考下面的例子

# cat /srv/bin/rotatelog.sh

#!/bin/bash

# run this script at 0:00

#Nginx Log Path

log_dir="/var/log/nginx"

date_dir=`date +%Y/%m/%d/%H`

mkdir -p ${log_dir}/${date_dir} > /dev/null 2>&1

mv ${log_dir}/access.log ${log_dir}/${date_dir}/access.log

mv ${log_dir}/error.log ${log_dir}/${date_dir}/error.log

kill -USR1 `cat /var/run/nginx.pid`

gzip ${log_dir}/${date_dir}/access.log &

gzip ${log_dir}/${date_dir}/error.log &

/etc/logrotate.d/nginx

如果是非源码安装，一般情况nginx都会自带日志切割处理配置文件。

# cat /etc/logrotate.d/nginx

/var/log/nginx/*.log {

daily

missingok

rotate 52

compress

3. nginx.conf 配置文件

3.1. 处理器配置

worker_processes = CPU 数量

user www;

worker_processes 1;

error_log /var/log/nginx/error.log warn;

pid /var/run/nginx.pid;

3.2. events 配置

连接数配置

events {

worker_connections  4096;

}

3.3. http 配置

缓冲区相关设置

自定义缓冲区相关设置

client_body_buffer_size 1K;

client_header_buffer_size 1k;

client_max_body_size 1k;

large_client_header_buffers 2 1k;

上传文件提示 client intended to send too large body，配置下面参数可以解决。

server {

...

client_max_body_size 200M;

}

超时设置

超时相关设置

client_body_timeout 10;

client_header_timeout 10;

keepalive_timeout 65;

send_timeout 10;

gzip

gzip on;

gzip_min_length 1000;

gzip_buffers 4 8k;

gzip_types text/plain text/css application/json application/x-javascript application/xml;

gzip on;

gzip_http_version 1.0;

gzip_disable "MSIE [1-6].";

gzip_types text/plain application/x-javascript text/css text/javascript;

gzip_types 压缩类型

gzip_types text/plain text/css application/javascript text/javascript application/x-javascript text/xml application/xml application/xml+rss application/json;

text/html 是 gzip_types 默认值，所以不要将text/html加入到gzip_types

测试，验证 gzip 正常工作

neo@netkiller:~/workspace$ curl -s -I -H 'Accept-Encoding: gzip,deflate' http://img.netkiller.cn/js/react.js | grep gzip

Content-Encoding: gzip

如果提示 Content-Encoding: gzip 便是配置正确

不仅仅只能压缩html,js,css还能压缩json

neo@netkiller:~$ curl -s -I -H 'Accept-Encoding: gzip,deflate' http://inf.netkiller.cn/list/json/2.json

HTTP/1.1 200 OK

Server: nginx

Date: Thu, 15 Dec 2016 03:36:31 GMT

Content-Type: application/json; charset=utf-8

Connection: keep-alive

Cache-Control: max-age=60

Access-Control-Allow-Origin: *

Access-Control-Allow-Headers: Content-Type,Origin

Access-Control-Allow-Methods: GET,OPTIONS

Content-Encoding: gzip

CDN支持

配置 gzip_proxied any; 后CDN才能识别 gzip

server_tokens off;

gzip on;

gzip_types text/plain text/css application/javascript text/javascript application/x-javascript text/xml application/xml application/xml+rss application/json;

gzip_proxied any;

使用包含配置文件配置 gzip

cat <<-EOF> /etc/nginx/conf.d/gzip.conf

gzip on;

gzip_vary on;

gzip_proxied any;

gzip_min_length 1000;

gzip_types text/plain text/css application/javascript application/json application/xml application/octet-stream;

EOF

# text/html 类型无需配置，否则会提示

# nginx: [warn] duplicate MIME type "text/html" in /etc/nginx/conf.d/default.conf

server_tokens

隐藏nginx版本号

http {

...

server_tokens off;

...

}

ssi

http {

ssi on;

}

location / {

ssi on;

ssi_silent_errors on;

ssi_types text/shtml;

}

ssi on;

ssi_silent_errors on;

ssi_types text/shtml;

ssi_value_length 256;

server_names_hash_bucket_size 128;

client_header_buffer_size 32k;

large_client_header_buffers 4 32k;

client_max_body_size 8m;

ssi_silent_errors 默认值是off，开启后在处理SSI文件出错时不输出错误提示:"[an error occurred while processing the directive] "

ssi_types 默认是ssi_types text/html，如果需要shtml支持，则需要设置：ssi_types text/shtml

ssi_value_length 默认值是 256，用于定义SSI参数的长度。

$request_body - HTTP POST 数据

用户日志

将 POST 数据记录到日志中

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for" - "$request_body"';

注意：用户登录通常使用POST方式，所以记录POST数据到日志会带来安全问题，例如用户密码泄露。

$request_body 用于缓存

因为nginx 使用 url 作为缓存的key ( Nginx 将url地址 md5后作为缓存的 key )，所以默认情况下 Nginx 只能处理 HTTP GET 缓存。

对于 HTTP POST 请求，提交数据放在HTTP Head 头部提交到服务器的， 提交前后URL始终不变，Nginx 无法区分相同网址两次请求的内容有变化。

但是我们可以自定义 缓存 key 例如： "$request_uri|$request_body" 我们将请求地址加上post内容作为缓存的key，这样nginx 便可以区分每次提交后的页面变化。

HTTP2 配置 SSL证书

自颁发证书

创建自颁发证书，SSL有两种证书模式，单向认证和双向认证，下面是单向认证模式。

mkdir -p /etc/pki/nginx/private/

cd /etc/pki/nginx/

openssl req -x509 -nodes -days 365 -newkey rsa:4096 -keyout /etc/pki/nginx/private/server.key -out /etc/pki/nginx/server.crt

建议使用域名命名证书

openssl req -x509 -nodes -days 365 -newkey rsa:4096 -keyout /etc/nginx/ssl/api.netkiller.cn.key -out /etc/nginx/ssl/api.netkiller.cn.crt

Generating a 4096 bit RSA private key

writing new private key to '/etc/nginx/ssl/api.netkiller.cn.key'

-----

You are about to be asked to enter information that will be incorporated

into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN.

There are quite a few fields but you can leave some blank

For some fields there will be a default value,

If you enter '.', the field will be left blank.

-----

Country Name (2 letter code) [XX]:CN

State or Province Name (full name) []:Guangdong

Locality Name (eg, city) [Default City]:Shenzhen

Organization Name (eg, company) [Default Company Ltd]:CF

Organizational Unit Name (eg, section) []:CF

Common Name (eg, your name or your server's hostname) []:api.netkiller.cn

Email Address []:netkiller@msn.com

注意: Common Name (eg, your name or your server's hostname) []:api.netkiller.cn 要跟你的 nginx server_name api.netkiller.cn 一样。

You are about to be asked to enter information that will be incorporated

into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN.

There are quite a few fields but you can leave some blank

For some fields there will be a default value,

If you enter '.', the field will be left blank.

Getting CA Private Key

Nginx 配置

mkdir /etc/nginx/ssl

cp server.crt server.key ca.crt /etc/nginx/ssl

cd /etc/nginx/ssl

/etc/nginx/conf.d/api.netkiller.cn.conf

server {

listen       443 ssl;

server_name  api.netkiller.cn;

access_log off;

ssl on;

ssl_certificate /etc/nginx/ssl/server.crt;

ssl_certificate_key /etc/nginx/ssl/server.key;

ssl_client_certificate /etc/nginx/ssl/ca.crt;

ssl_verify_client on;

location / {

proxy_pass http://localhost:8443;

}

}

重启 nginx 服务器

root@VM_7_221_centos /etc/nginx % systemctl restart nginx

测试双向认证

首先直接请求

root@VM_7_221_centos /etc/nginx % curl -k https://api.netkiller.cn/

<html>

<head><title>400 No required SSL certificate was sent</title></head>

<body bgcolor="white">

<center><h1>400 Bad Request</h1></center>

<center>No required SSL certificate was sent</center>

<hr><center>nginx</center>

</body>

</html>

使用证书请求

curl --insecure --key client.key --cert ./client.crt:123456  https://api.netkiller.cn

注意： --cert 参数需要写入路径和密码

server_name 配置

匹配所有域名

server_name _;

泛解析主机

server {

listen       80;

server_name  example.org  www.example.org;

...

}

server {

listen       80;

server_name  *.example.org;

...

}

server {

listen       80;

server_name  mail.*;

...

}

server {

listen       80;

server_name  ~^(?<user>.+)\.example\.net$;

...

}

location

location / {

root /www;

index index.html index.htm;

}

禁止访问特定目录

location 匹配到特定的 path 将拒绝用户访问。

location ~ /\.ht {

deny  all;

}

location ~ ^/(config|include)/ {

deny all;

break;

}

引用document_root之外的资源

引用document_root之外的资源需要 root 绝对路径指向目标文件夹

location / {

root /www/example.com/m.example.com;

try_files $uri $uri/ @proxy;

}

location ^~ /module/ {

root /www/example.com/www.example.com;

}

# 下面的写法是错误的，通过error_log 我们可以看到被定为到/www/example.com/m.example.com/module

location /module/ {

root /www/example.com/www.example.com;

}

处理扩展名

location ~ \.php$ {

root           /opt/netkiller.cn/cms.netkiller.cn;

fastcgi_pass   127.0.0.1:9000;

fastcgi_index  index.php;

fastcgi_param  SCRIPT_FILENAME  /opt/netkiller.cn/cms.netkiller.cn$fastcgi_script_name;

include        fastcgi_params;

}

location 中关闭日志

location = /favicon.ico {

log_not_found off;

access_log off;

}

location = /robots.txt {

allow all;

log_not_found off;

access_log off;

}

匹配多个目录

location ~ /(dev|stage|prod) {

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header REMOTE-HOST $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_pass http://api.netkiller.cn:8080;

}

root 通过$host智能匹配目录

为每个host创建一个目录太麻烦，

server {

listen 80;

server_name www.netkiller.cn news.netkiller.cn bbs.netkiller.cn;

charset utf-8;

access_log /var/log/nginx/test.access.log main;

location / {

root /www/netkiller.cn/$host;

index index.html index.htm;

}

}

处理主机名中的域

server {

listen 80;

server_name *.example.com example.com;

if ($host = 'example.com' ) {

rewrite ^/(.*)$ http://www.example.com/$1 permanent;

}

if ( $host ~* (.*)\.(.*)\.(.*)) {

set $subdomain $1;

set $domain $2.$3;

}

root /www/$domain/$subdomain;

index index.html index.php;

location ~ .*\.(php|shtml)?$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

include fcgi.conf;

}

}

或者采用这种格式 /www/example.com/www.example.com

root /www/$domain/$host;

更简洁的方法，只需在 /www/下面创建 域名目录即可例如/www/www.example.com

server {

listen 80;

server_name *.example.com example.com;

if ($host = 'example.com' ) {

rewrite ^/(.*)$ http://www.example.com/$1 permanent;

}

root /www/$host;

index index.html index.php;

location ~ .*\.(php|shtml)?$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

include fcgi.conf;

}

}

expires

expires 格式

例 1.2. Expires Examples

expires 1 January, 1970, 00:00:01 GMT;

expires 60s;

expires 30m;

expires 24h;

expires 1d;

expires max;

expires off;

expires 24h;

expires modified +24h;

expires @15h30m;

expires 0;

expires -1;

expires epoch;

add_header Cache-Control private;

注意：expires仅仅适用于200, 204, 301, 302,304

单个文件匹配

location ~* \.css$ {

expires 30d;

}

扩展名匹配

#图片类资源缓存5天，并且不记录请求日志

location ~ .*\.(ico|gif|jpg|jpeg|png|bmp|swf)$

{

expires 5d;

access_log off;

}

#css/js 缓存一天，不记录请求日志

location ~ .*\.(js|css)$

{

access_log off;

expires 1d;

add_header Pragma public;

add_header Cache-Control "public";

}

location ~ .*\.(htm|html|gif|jpg|jpeg|png|bmp|swf|ioc|rar|zip|txt|flv|mid|doc|ppt|pdf|xls|mp3|wma)$

{

expires 30d;

}

location ~ .*\.(js|css)$

{

expires 1h;

}

location ~* \.(js|css|jpg|jpeg|gif|png|swf)$ {

if (-f $request_filename) {

expires 1h;

break;

}

}

location ~* \.(jpg|jpeg|gif|css|png|js|ico)$ {

expires max;

}

#cache control: all statics are cacheable for 24 hours

location / {

if ($request_uri ~* \.(ico|css|js|gif|jpe?g|png)$) {

expires 72h;

break;

}

}

例 1.3. nginx expires

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$ {

expires 1d;

access_log off;

}

location ~ .*\.(js|css)$ {

expires 1d;

access_log off;

}

location ~ .*\.(html|htm)$

{

expires 1d;

access_log off;

}

通过 add_header / more_set_headers 设置缓存

add_header 实例

location ~* \.(?:ico|css|js|gif|jpe?g|png)$ {

expires 30d;

add_header Pragma public;

add_header Cache-Control "public";

}

more_set_headers 实例

location ~ \.(ico|pdf|flv|jp?g|png|gif|js|css|webp|swf)(\.gz)?(\?.*)?$ {

more_set_headers 'Cache-Control: max-age=86400';

...

proxy_cache_valid 200 2592000;

...

}

s-maxage 作用于 Proxy

location ~ \.(ico|pdf|flv|jp?g|png|gif|js|css|webp|swf)(\.gz)?(\?.*)?$ {

more_set_headers 'Cache-Control: s-maxage=86400';

}

$request_uri

if ($request_uri ~* "\.(ico|css|js|gif|jpe?g|png)\?[0-9]+$") {

expires max;

break;

}

下面例子是缓存 /detail/html/5/4/321035.html， 但排除 /detail/html/5/4/0.html

if ($request_uri ~ ^/detail/html/[0-9]+/[0-9]/[^0][0-9]+\.html ) {

expires 1d;

}

$request_filename

if (-f $request_filename) {

expires 1d;

}

access

#防止access文件被下载

location ~ /\.ht {

deny all;

}

location ~ ^/upload/.*\.php$

{

deny all;

}

location ~ ^/static/images/.*\.php$

{

deny all;

}

location ~ /\.ht {

deny all;

}

location ~ .*\.(sqlite|sq3)$ {

deny all;

}

IP 地址

location / {

allow 192.168.1.0/24;

allow 10.1.1.0/16;

allow 2001:0db8::/32;

deny all;

}

限制IP访问*.php文件

location ~ ^/private/.*\.php$

{

allow 222.222.22.35;

allow 192.168.1.0/249;

deny all;

}

autoindex

开启目录浏览

# vim /etc/nginx/sites-enabled/default

location / {

autoindex on;

}

# /etc/init.d/nginx reload

Reloading nginx configuration: nginx.

另外Nginx的目录流量有两个比较有用的参数，可以根据自己的需求添加：

autoindex_exact_size off;

默认为on，显示出文件的确切大小，单位是bytes。

改为off后，显示出文件的大概大小，单位是kB或者MB或者GB

autoindex_localtime on;

默认为off，显示的文件时间为GMT时间。

改为on后，显示的文件时间为文件的服务器时间

try_files

server {

listen 80;

server_name www.example.com example.com;

location / {

try_files $uri $uri/ /index.php?/$request_uri;

}

location /example {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /www/example$fastcgi_script_name;

include fastcgi_params;

}

location ~ /\.ht {

deny all;

}

}

add_header

Cache

# 相关页面设置Cache-Control头信息

if ($request_uri ~* "^/$|^/news/.+/|^/info/.+/") {

add_header Cache-Control max-age=3600;

}

if ($request_uri ~* "^/suggest/|^/categories/") {

add_header Cache-Control max-age=86400;

}

add_header     Nginx-Cache     "HIT  from  www.example.com";

or

add_header     Nginx-Cache     "$upstream_cache_status  from  www.example.com";

Access-Control-Allow

location ~* \.(eot|ttf|woff)$ {

add_header Access-Control-Allow-Origin *;

}

location /js/ {

add_header Access-Control-Allow-Origin https://www.mydomain.com/;

3.6. rewrite

Rewrite Flags

last - 基本上都用这个Flag。

break - 中止Rewirte，不在继续匹配

redirect - 返回临时重定向的HTTP状态302

permanent - 返回永久重定向的HTTP状态301

文件及目录匹配，其中：

-f和!-f用来判断是否存在文件

-d和!-d用来判断是否存在目录

-e和!-e用来判断是否存在文件或目录

-x和!-x用来判断文件是否可执行

正则表达式全部符号解释

~ 为区分大小写匹配

~* 为不区分大小写匹配

!~和!~* 分别为区分大小写不匹配及不区分大小写不匹配

(pattern) 匹配 pattern 并获取这一匹配。所获取的匹配可以从产生的 Matches 集合得到，在VBScript 中使用 SubMatches 集合，在JScript 中则使用 $0…$9 属性。要匹配圆括号字符，请使用 ‘\(’ 或 ‘\)’。

^ 匹配输入字符串的开始位置。

$ 匹配输入字符串的结束位置。

server {

listen 80;

server_name www.example.com example.com ;

if ($host = "example.com" )

{

rewrite ^/(.*)$ http://www.example.com/$1 permanent;

}

if ($host != "www.example.com" )

{

rewrite ^/(.*)$ http://www.example.com/$1 permanent;

}

}

处理泛解析

if ($host ~ '(.*)\.example\.com' ) {

set $subdomain $1;

rewrite "^/(.*)$" /$subdomain/$1;

}

处理扩展名

location ~* \.(js|css|jpg|jpeg|gif|png|swf)$ {

if (!-f $request_filename){

rewrite /(.*) http://images.example.com/$1;

}

}

http get 参数处理

需求如下

原理地址：

http://www.netkiller.cn/redirect/index.html?skuid=133

目的地址：

http://www.netkiller.cn/to/133.html

注意：nginx rewrite 并不支持http get 参数处理，也就是说“?”之后的内容rewrite根部获取不到。

下面的例子是行不通的

rewrite ^/redirect/index\.html\?skuid=(\d+)$ /to/$1.html permanent ;

我们需要通过正在查出参数，然后赋值一个变量，再将变量传递给rewrite。具体做法是：

server {

listen       80;

server_name www.netkiller.cn;

#charset koi8-r;

access_log  /var/log/nginx/test.access.log  main;

location / {

root   /www/test;

index  index.html;

if ($request_uri ~* "^/redirect/index\.html\?skuid=([0-9]+)$") {

set $argv1 $1;

rewrite .* /to/$argv1.html? permanent;

}

}

}

测试结果

[neo@netkiller conf.d]$ curl -I http://www.netkiller.cn/redirect/index.html?skuid=133

HTTP/1.1 301 Moved Permanently

Server: nginx

Date: Tue, 12 Apr 2016 06:59:33 GMT

Content-Type: text/html

Content-Length: 178

Location: http://www.netkiller.cn/to/133.html

Connection: keep-alive

正则取非

需求如下，除了2015年保留，其他所有页面重定向到新页面

rewrite ^/promotion/(?!2015\/)(.*) https://www.netkiller.cn/promotion.html permanent;

去掉扩展名

需求

http://www.example.com/article/10 => http://www.example.com/article/10.html

location / {

if (!-e $request_filename){

rewrite ^(.*)$ /$1.html last;

break;

}

}

rewrite + proxy_pass

需求如下

http://www.example.com/images/logo.jpg => http://images.example.com/logo.jpg

如果直接 proxy_pass http://images.example.com; 的后果是http://images.example.com/images/logo.jpg，我们需要去掉images目录，这里使用rewrite /images/(.+)$ /$1 break;实现

location ^~ /images/ {

rewrite /images/(.+)$ /$1 break;

proxy_pass http://images.example.com;

break;

}

request_filename + proxy_pass

如果文件不存在，那么去指定的节点上寻找

location / {

root  /www;

proxy_intercept_errors  on;

if (!-f $request_filename) {

proxy_pass http://172.16.1.1;

break;

}

}

location / {

root  /www/images;

proxy_intercept_errors  on;

if (!-f $request_filename) {

proxy_pass http://172.16.1.2;

break;

}

}

$request_uri 与 proxy_pass 联合使用

server {

try_files 与 proxy_pass 共用

需求，在web目录下索引静态，如果不存在便进入proxy处理，通常proxy后面是tomcat等应用服务器。

我们可以使用 try_files 与 proxy_pass 实现我们的需求

server {

listen       80;

server_name  m.netkiller.cn;

charset utf-8;

access_log  /var/log/nginx/m.netkiller.cn.access.log;

location / {

try_files $uri $uri/ @proxy;

}

location @proxy {

proxy_pass http://127.0.0.1:8000;

proxy_set_header    Host    $host;

proxy_set_header    X-Real-IP   $remote_addr;

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

}

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html

#

error_page   500 502 503 504  /50x.html;

location = /50x.html {

}

# deny access to .htaccess files, if Apache's document root

Proxy 与 SSI

背景：nginx + tomcat 模式，nginx 开启 SSI , Tomcat 动态页面中输出 SSI 标签

# cat  /etc/nginx/conf.d/www.netkiller.cn.conf

server {

listen       80;

server_name  www.netkiller.cn;

charset utf-8;

access_log  /var/log/nginx/www.netkiller.cn.access.log;

location / {

#index  index.html index.htm;

proxy_pass http://127.0.0.1:8080;

proxy_set_header    Host    $host;

proxy_set_header    X-Real-IP   $remote_addr;

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

}

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html

#

error_page   500 502 503 504  /50x.html;

location = /50x.html {

}

}

test.jsp 文件

%>

<center>

<h1><%=lgtime%></h1>

</center>

<!--# set var="test" value="Hello netkiller!" -->

<!--# echo var="test" -->

</body>

测试并查看源码，你会看到SSI标签

<!--# set var="test" value="Hello netkiller!" -->

<!--# echo var="test" -->

解决方案

location / {

ssi on;

proxy_set_header Accept-Encoding "";

proxy_pass http://127.0.0.1:8080;

proxy_set_header    Host    $host;

proxy_set_header    X-Real-IP   $remote_addr;

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

}

再次测试，你将看不到SSI标签，只能看到文本输出Hello netkiller!

Host

Proxy 通过IP地址访问目的主机，如果目的主机是虚拟主机，你就需要告诉目的主机是那个域名。

proxy_set_header Host www.example.com;

proxy_set_header Host $server_name;

server_name  www.example.com;

charset utf-8;

access_log  /var/log/nginx/www.example.com.access.log  main;

隐藏头部信息

例如响应头：

Content-Encoding: gzip

Content-Type: text/html; charset=UTF-8

Date: Thu, 04 Feb 2018 02:20:36 GMT

Transfer-Encoding: chunked

Vary: Accept-Encoding

X-Powered-By: PHP/7.2.0

隐藏 PHP 版本信息

proxy_hide_header X-Powered-By;

忽略头

location /images/ {

proxy_cache my_cache;

proxy_ignore_headers Cache-Control;

proxy_cache_valid any 30m;

...

}

proxy_pass_request_headers 透传 Header

有时用户会设置自定义的 HTTP 头信息，这些不符合 HTTP 的头信息如果需要会被 proxy_pass 过滤并丢弃。

proxy_pass_request_headers off;

默认系统是开启的

proxy_pass_request_headers on;

timeout 超时时间

proxy_connect_timeout: 链接超时设置，后端服务器连接的超时时间，发起握手等候响应超时时间。

proxy_read_timeout: 连接成功后，等候后端服务器响应时间，其实已经进入后端的排队之中等候处理，也可以说是后端服务器处理请求的时间。

proxy_send_timeout: 后端服务器数据回传时间，就是在规定时间之内后端服务器必须传完所有的数据。

上面的jsessionid处理方式

Nginx -> Nginx -> Tomcat

背景各种原因需要再Nginx前面再增加一层Nginx虽然需求很变态，本着学习的目的试了试。

这里还使用了 http2 加速 nginx ssl http2 -> nginx ssl http2 -> Tomcat 8080

server {

listen       443 ssl http2;

server_name  www.netkiller.cn;

ssl_certificate      ssl/netkiller.cn.crt;

ssl_certificate_key  ssl/netkiller.cn.key;

#    ssl_session_cache    shared:SSL:1m;

#    ssl_session_timeout  5m;

#    ssl_ciphers  HIGH:!aNULL:!MD5;

#    ssl_prefer_server_ciphers  on;

location / {

proxy_buffers 16 4k;

proxy_buffer_size 2k;

proxy_pass https://www.netkiller.cn;

proxy_pass_header   Set-Cookie;

add_header From     www.netkiller.cn;

proxy_set_header    Cookie $http_cookie;

proxy_set_header    Host    $host;

proxy_set_header    X-Real-IP   $remote_addr;

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_cookie_domain www.netkiller.cn netkiller.cn;

#proxy_cookie_path / "/; secure; HttpOnly";

proxy_set_header Accept-Encoding "";

proxy_ignore_client_abort  on;

}

}

有几点需要注意：

如果是443你需要挂在证书，需要透传cookie给目的主机，否则你将无法支持Session，应用程序需要从 X-Forwarded-For 获取IP地址。

Proxy 处理 Cookie

下面是一个通过 proxy_pass 代理live800的案例，我们需要处理几个地方：

Host头处理，Cookie传递，替换原因页面中的域名，替换文件有html,css,xml,css,js

location ~ ^/k800 {

#rewrite              ^/live800/(.*)  /$1 break;

proxy_pass           http://118.23.24.15;

proxy_pass_header   Set-Cookie;

proxy_set_header    Accept-Encoding "";

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header    Host www.example.com;

proxy_set_header    Cookie $http_cookie;

sub_filter_types text/html text/css text/xml text/css text/javascript;

sub_filter 'www.example.com'  '$host';

sub_filter_once off;

}

Proxy 添加 CORS 头

server {

listen       80;

listen 443 ssl http2;

server_name api.netkiller.cn;

ssl_certificate ssl/netkiller.cn.crt;

ssl_certificate_key ssl/netkiller.cn.key;

ssl_session_cache shared:SSL:20m;

ssl_session_timeout 60m;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

charset utf-8;

access_log  /var/log/nginx/api.netkiller.cn.access.log  main;

location / {

proxy_pass      http://127.0.0.1:7000;

}

location ^~ /api {

add_header Access-Control-Allow-Origin *;

add_header Access-Control-Allow-Headers Content-Type,Origin;

add_header Access-Control-Allow-Methods GET,OPTIONS;

proxy_pass http://other.example.com/api/;

}

}

通过 Proxy 汉化 restful 接口

通过 proxy 汉化 restful 接口返回的 json 字符串。

背景，有这样一个需求，前端HTML5通过ajax与restful交互，ajax会显示接口返回json数据，由于js做了混淆无法修改与restful交互的逻辑，但是json反馈结果需要汉化。

汉化前接口如下，返回message为 "message":"Full authentication is required to access this resource"

neo@netkiller ~/workspace/Developer/Python % curl http://api.netkiller.cn/restful/member/get/1.json

{"timestamp":1505206067543,"status":401,"error":"Unauthorized","message":"Full authentication is required to access this resource","path":"/restful/member/get/1.json"}

建立一个代理服务器，代理介于用户和接口之间，ajax 访问接口需要经过这个代理服务器中转。

增加 /etc/nginx/conf.d/api.netkiller.cn.conf 配置文件

server {

listen 80;

server_name api.netkiller.cn;

charset utf-8;

location / {

proxy_pass http://localhost:8443;

proxy_http_version 1.1;

proxy_set_header    Host    $host;

sub_filter_types application/json;

sub_filter 'Full authentication is required to access this resource'  '用户验证错误';

sub_filter_once off;

}

}

所谓汉化就是字符串替换，使用nginx sub_filter 模块。

重新启动 nginx 然后测试汉化效果

neo@netkiller ~/workspace/Developer/Python % curl http://api.netkiller.cn/restful/member/get/1.json

{"timestamp":1505208931927,"status":401,"error":"Unauthorized","message":"用户验证错误","path":"/restful/member/get/1.json"}

现在我们看到效果是 "message":"用户验证错误"

HTTP Auth 认证冲突

nginx 代理 springboot，Springboot 使用了 JWT 认证，HTTP头为 Authorization: Bearer {BASE64}

admin.netkiller.cn 后台需要限制登陆，公司没有固定IP地址，尝试了 VPN 方案，被封。最终决定使用 HTTP Auth，HTTP Auth 使用 HTTP Authorization: Basic {BASE64}。

问题来了，由于HTTP的 key 都是 Authorization，Authorization: Basic 会覆盖掉 Authorization: Bearer 导致 Springboot 无法认证返回 401.

使用下面👇配置解决，注意⚠️调试的时候需要每次关闭浏览器，否则会保留状态，不生效。

auth_basic off;

proxy_pass_request_headers on;

完成的例子

server {

listen       80;

listen       443 ssl http2;

Spawn-fcgi

We still need a script to start our fast cgi processes. We will extract one from Lighttpd. and then disable start script of lighttpd

$ sudo apt-get install lighttpd

$ sudo chmod -x /etc/init.d/lighttpd

$ sudo touch /usr/bin/php-fastcgi

$ sudo vim /usr/bin/php-fastcgi

#!/bin/sh

fastcgi daemon

$ sudo touch /etc/init.d/nginx-fastcgi

$ sudo chmod +x /usr/bin/php-fastcgi

$ sudo vim /etc/init.d/nginx-fastcgi

This is also a new empty file, add the following and save:

#!/bin/bash

PHP_SCRIPT=/usr/bin/php-fastcgi

RETVAL=0

case "$1" in

start)

$PHP_SCRIPT

RETVAL=$?

;;

stop)

killall -9 php

RETVAL=$?

;;

restart)

killall -9 php

$PHP_SCRIPT

RETVAL=$?

;;

*)

echo "Usage: nginx-fastcgi {start|stop|restart}"

exit 1

;;

esac

exit $RETVAL

We need to change some permissions to make this all work.

$ sudo chmod +x /etc/init.d/nginx-fastcgi

limit_zone   one  $binary_remote_addr  10m;

server {

location /download/ {

limit_conn   one  1;

}

4.8. image_filter

image_filter 配置项:

image_filter off;　　　　在所在location关闭模块处理。

image_filter test;　　确保应答是JPEG，GIF或PNG格式的图像。否则错误 415 (Unsupported Media Type) 将被返回。

image_filter size;　　以JSON格式返回图像信息。

image_filter rotate 90 | 180 | 270;　　将图像逆时针旋转指定角度。 参数的值可以包含变量。 可以单独使用，或与 resize 和 crop 变换同时使用.

image_filter resize width height;　　按比例缩小图像至指定大小。 如果想只指定其中一维，另一维可以指定为： “-”。 如果有错误发生，服务器会返回 415 (Unsupported Media Type). 参数的值可以包含变量。 当与 rotate 参数同时使用时, 旋转发生在缩放 之后。

image_filter crop width height;　　按比例以图像的最短边为准对图像大小进行缩小，然后裁剪另一边多出来的部分。 如果想只指定其中一维，另一维可以指定为： “-”。 如果有错误发生，服务器会返回 415 (Unsupported Media Type). 参数的值可以包含变量。 当与 rotate 参数同时使用时, 旋转发生在裁剪 之前。

image_filter_buffer 配置项：

image_filter_buffer size; 例如 image_filter_buffer 1M;　设置用来读图像的缓冲区的最大值。 若图像超过这个大小，服务器会返回 415 (Unsupported Media Type).

image_filter_jpeg_quality quality; 例如 image_filter_jpeg_quality 75;设置变换后的JPEG图像的 质量 。 可配置值： 1 ~ 100 。 更小的值意味着更差的图像质量以及更少需要传输的数据。 推荐的最大值是95. 参数的值可以包含变量。

image_filter_sharpen percent; image_filter_sharpen 0;　　增加最终图像的锐度。 锐度百分比可以超过100. 0为关闭锐化。 参数的值可以包含变量。

image_filter_transparency on|off; image_filter_transparency on;定义当对PNG，或者GIF图像进行颜色变换时是否需要保留透明度。 损失透明度有可能可以获得更高的图像质量。 PNG图像中的alpha通道的透明度默认会一直被保留。

比如所有的图片并修改尺寸为 800x600

location ~* \.(jpg|gif|png)$ {

image_filter resize 800 600;

}

匹配images目录所有图片并修改尺寸为1920x1080

location ~* /images/.*\.(jpg|gif|png)$ {

image_filter resize 1920 1080;

}

再比如用url来指定

location ~* (.*\.(jpg|gif|png))!(.*)x(.*)$ {

set $width      $3;

set $height     $4;

rewrite "(.*\.(jpg|gif|png))(.*)$" $1;

}

location ~* .*\.(jpg|gif|png)$ {

image_filter resize $width $height;

}

location ~* /images/(.+)_(d+)x(d+).(jpg|gif|png)$ {

set $height $2;

set $width $3;

if ($height = "0") {

rewrite /images/(.+)_(d+)x(d+).(jpg|gif|png)$ /images/$1.$4 last;

}

if ($width = "0") {

rewrite /images/(.+)_(d+)x(d+).(jpg|gif|png)$ /images/$1.$4 last;

}

#根据给定的长宽生成缩略图

image_filter resize $height $width;

#原图最大2M，要裁剪的图片超过2M返回415错误，根据你的需求调节参数image_filter_buffer

image_filter_buffer 2M;

#error_page  415      /images/404.jpg;

try_files /images/$1.$4  /images/404.jpg;

}

location ~* /images {

}

location ~* ^/images/resize/([\d\-]+)_([\d\-]+)/(.+) {

alias /www/example.com/img.example.com/$3;

image_filter test;

image_filter resize $1 $2;

image_filter_buffer 2M;

image_filter_jpeg_quality 95;

image_filter_sharpen 90;

expires 60d;

}

4.9. ngx_stream_proxy_module

ngx_stream_proxy_module 用法与 ngx_http_proxy_module 及其相似, 前者用于tcp代理或负载均衡。后者只能用于 http 的代理

注意模块的proxy_pass指令只能在server段使用, 提供域名或ip地址和端口转发，协议可以是tcp，也可以是udp。

server {

listen 127.0.0.1:80;

proxy_pass 127.0.0.1:8080;

}

server {

listen 25;

proxy_connect_timeout 1s;

proxy_timeout 1m;

proxy_pass mail.example.com:25;

}

server {

listen 53 udp;

proxy_responses 1;

proxy_timeout 20s;

proxy_pass dns.example.com:53;

}

server {

listen [::1]:8000;

proxy_pass unix:/tmp/stream.socket;

}

5.3. Session 的 Cookie 域处理

环境

User -> Http2 CDN -> Http2 Nginx -> proxy_pass 1.1 -> Tomcat

背景，默认情况下 tomcat 不会主动推送 Cookie 域，例如下面的HTTP头

Set-Cookie: JSESSIONID=8542E9F58C71937B3ABC97F002CE039F;path=/;HttpOnly

这样带来一个问题，在浏览器中默认Cookie域等于 HTTP_HOST 头（www.example.com），如果网站只有一个域名没有问题，如果想共享Cookie给子域名下所有域名 *.example.com 无法显示。

通过配置Tomcat sessionCookieDomain="example.com" 可以实现推送 Cookie 域

<Context path="" docBase="/www/netkiller.cn/www.netkiller.cn"  reloadable="false" sessionCookieName="PHPSESSID" sessionCookieDomain="netkiller.cn" sessionCookiePath="/" />

这样的配置一般用户的需求都可以满足。我的需求中还有一项，在服务器绑定多个域名（二级域名）。问题来了 Tomcat 将始终推送 netkiller.cn 这个域。其他域名无法正确设置Cookie

$ curl -s -I -H https://www.netkiller.cn/index.jsp | grep Set-Cookie

Set-Cookie: PHPSESSID=4DBAF36AA7B79CE1ACBA8DD67702B945;domain=netkiller.cn;path=/;HttpOnly

$ curl -s -I -H 'Host: www.test.com' https://www.test.com/index.jsp | grep Set-Cookie

Set-Cookie: PHPSESSID=4DBAF36AA7B79CE1ACBA8DD67702B945;domain=netkiller.cn;path=/;HttpOnly

$ curl -s -I -H 'Host: www.example.com' https://www.example.com/index.jsp | grep Set-Cookie

Set-Cookie: PHPSESSID=4DBAF36AA7B79CE1ACBA8DD67702B945;domain=netkiller.cn;path=/;HttpOnly

怎样处理需求呢，我想了两个方案，一个方案是在Nginx中配置，另一个方案是在代码中解决。其中Nginx处理起来比较灵活无需开发测试介入，最终选择nginx方案

server {

listen       443 ssl http2 default_server;

server_name _;

location ~ \.(do|jsp|action)$ {

ssi on;

proxy_set_header Accept-Encoding "";

proxy_pass http://127.0.0.1:8080;

proxy_set_header    Host    $host;

proxy_set_header    X-Real-IP   $remote_addr;

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

set $domain $host;

if ($host ~* ^([^\.]+)\.([^\.]+)\.([^\.]+)$) {

set $domain $2.$3;

}

proxy_cookie_domain netkiller.cn $domain;

}

}

server_name _; 接受任何域名绑定，default_server 将vhost 设置为默认主机。最终测试结果：

$ curl -s -I -H https://www.netkiller.cn/index.jsp | grep Set-Cookie

Set-Cookie: PHPSESSID=4DBAF36AA7B79CE1ACBA8DD67702B945;domain=netkiller.cn;path=/;HttpOnly

$ curl -s -I -H https://www.example.com/index.jsp | grep Set-Cookie

Set-Cookie: PHPSESSID=4DBAF36AA7B79CE1ACBA8DD67702B945;domain=example.com;path=/;HttpOnly

$ curl -s -I -H https://www.domain.com/index.jsp | grep Set-Cookie

Set-Cookie: PHPSESSID=4DBAF36AA7B79CE1ACBA8DD67702B945;domain=domain.com;path=/;HttpOnly

配置 proxy_ignore_client_abort on;

location / {

ssi on;

proxy_set_header Accept-Encoding "";

proxy_pass http://127.0.0.1:8080;

proxy_set_header    Host    $host;

proxy_set_header    X-Real-IP   $remote_addr;

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_ignore_client_abort  on;

}

6.4. 502 Bad Gateway?

6.4.1.

502 Bad Gateway

error.log 提示：

upstream sent too big header while reading response header from upstream?

修改fastcgi配置

location ~ \.php$ {

fastcgi_buffers 8 16k;

fastcgi_buffer_size 32k;

。。。

。。。

}

6.5. 504 Gateway Time-out

6.5.1.

504 Gateway Time-out

问题一般出现在 nginx 通过 proxy_pass 代理其他服务的场景

由于代理的后端服务处理时间较长，超过了timeout阀值，就会报出 504 错误

修改fastcgi配置

client_max_body_size     50m; //文件大小限制，默认1m

client_header_timeout    1m;

client_body_timeout      1m;

proxy_connect_timeout     60s;

proxy_read_timeout      1m;

proxy_send_timeout      1m;

每个参数的意思：

client_max_body_size 限制上传数据的的大小，若超过所设定的大小，返回413错误。

client_header_timeout 读取请求头的超时时间，若超过所设定的大小，返回408错误。

client_body_timeout 读取请求实体的超时时间，若超过所设定的大小，返回413错误。

proxy_connect_timeout 此参数为等待的最长时间，默认为60秒，官方推荐最长不要超过75秒。

proxy_read_timeout http请求代理后，nginx会等待处理结果。此参数即为服务器响应时间，默认60秒。

proxy_send_timeout http请求被服务器处理完后，把数据传返回给Nginx的用时，默认60秒。

6.6. proxy_pass

nginx: [emerg] "proxy_pass" cannot have URI part in location given by regular expression, or inside named location, or inside "if" statement, or inside "limit_except" block in /etc/nginx/conf.d/www.mydomain.com.conf:25

nginx: configuration file /etc/nginx/nginx.conf test failed

在location,if中使用证则匹配proxy_pass末尾不能写/

if ($request_uri ~* "^/info/{cn|tw}/{news|info}/\d\.html") {

proxy_pass http://info.example.com/;

break;

}

location ~ ^/info/ {

proxy_pass http://info.example.com/;

break;

}

proxy_pass http://info.example.com/; 改为 proxy_pass http://info.example.com; 可以解决

6.7. proxy_pass SESSION 丢失问题

如果用户Cookie信息没有经过 proxy_pass 传递给最终服务器，SESSION信息将丢失，解决方案

proxy_set_header   Cookie $http_cookie;

6.8. [alert] 55785#0: *11449 socket() failed (24: Too many open files) while connecting to upstream

配置 worker_rlimit_nofile 参数即可

user  nginx;

worker_processes  8;

worker_rlimit_nofile 65530;

配置 ulimit 也能达到同样效果，但我更喜欢 worker_rlimit_nofile 因为它仅仅作用于nginx,而不是全局配置。

6.9. server_name 与 SSI 注意事项

server_name www.example.com www.example.net www.example.org;

下来SSI标签无论你使用那个域名访问，输出永远是server_name的第一域名www.example.com

<!--#echo var="SERVER_NAME"-->

需要通过SERVER_NAME判定展示不同结果时需要注意。

6.10. location 跨 document_root 引用，引用 document_root 之外的资源

下面的例子是 Document root 是 /www/netkiller.com/m.netkiller.com， 我们需要 /www/netkiller.com/www.netkiller.com 中的资源。

server {

listen       80;

server_name  m.netkiller.com;

charset utf-8;

access_log  /var/log/nginx/m.netkiller.com.access.log;

error_log  /var/log/nginx/m.netkiller.com.error.log;

location / {

root /www/netkiller.com/m.netkiller.com;

index.html

}

location /module {

root /www/netkiller.com/www.netkiller.com;

}

}

server {

listen       80;

server_name  m.netkiller.com;

charset utf-8;

access_log  /var/log/nginx/m.netkiller.com.access.log;

error_log  /var/log/nginx/m.netkiller.com.error.log;

location / {

root /www/netkiller.com/m.netkiller.com;

index.html

}

location ^~ /module/ {

root /www/netkiller.com/www.netkiller.com;

}

}

上面的例子location /module 是指 /www/netkiller.com/www.netkiller.com + /module，如果 /www/netkiller.com/www.netkiller.com 目录下面没有 module 目录是出现404， error.log显示 "/www/netkiller.cn/www.netkiller.cn/module/index.html" failed (2: No such file or directory)

6.11. nginx: [warn] duplicate MIME type "text/html" in /etc/nginx/nginx.conf

text/html 是 gzip_types 默认值，所以不要将text/html加入到gzip_types列表内

6.12. 127.0.0.1:8080 failed

链接本地端口失败，已经关闭防火墙，同时使用 curl http://127.0.0.1:8080 一切正常

第 2 章 Caddy

Caddy is a powerful, enterprise-ready, open source web server with automatic HTTPS written in Go.

1. 安装 Caddy

2. 启动 Caddy

前台运行

caddy run --config /etc/caddy/Caddyfile --adapter caddyfile

2.1. 开启 QUIC

caddy run --config /etc/caddy/Caddyfile --adapter caddyfile --quic

3. 命令行

3.1. 文件服务器

将当前目录作为文件服务器的根目录

$ caddy file-server

指定端口

$ caddy file-server --listen :8080

不打开 index.html，显示文件目录

$ caddy file-server --browse

指定文件服务器根目录

$ caddy file-server --root ~/public_html

4. /etc/caddy/Caddyfile

https://caddyserver.com/docs/caddyfile

4.1. 监听地址

localhost

example.com

:443

http://example.com

localhost:8080

127.0.0.1

[::1]:2015

example.com/foo/*

*.example.com

http://

localhost:8080, example.com, www.example.com

泛解析

*.example.com

4.2. 反向代理

http://api.netkiller.cn {

reverse_proxy /* http://192.168.30.10:8080

tls netkiller@msn.com

}

推送 X-Forwarded-For 头

http://www.netkiller.cn {

root * /opt/netkiller.cn/www.netkiller.cn

file_server

reverse_proxy /api/* 192.168.30.10:8080 {

header_up X-Real-IP {http.request.remote.host}

header_up X-Forwarded-For {http.request.remote.host}

}

}

反向代理自签名证书，添加 tls_insecure_skip_verify 配置项

netkiller.cn {

reverse_proxy * {

to https://192.168.0.10

transport http {

tls_insecure_skip_verify

}

}

}

api.netkiller.cn {

reverse_proxy * {

to 192.168.10.10:443

transport http {

tls

tls_insecure_skip_verify

}

}

}

反向代理URL前缀问题

举例：

www.netkiller.cn {

reverse_proxy /api/* http://api.netkiller.cn:8080

}

访问URL:

http://www.netkiller.cn/api/adduser

实际访问的URL是:

http://api.netkiller.cn:8080/api/adduser

我们需要的URL是：

http://api.netkiller.cn:8080/adduser

解决方案

www.netkiller.cn {

route /api* {

uri strip_prefix /api

reverse_proxy api.netkiller.cn:8088

}

}

1.6. 同时运行多实例

创建工作目录

mkdir /srv/apache-tomcat

每个端口一个目录

tar zxvf apache-tomcat-7.0.x.tar.gz

mv  apache-tomcat-7.0.x /srv/apache-tomcat/8080

tar zxvf apache-tomcat-7.0.x.tar.gz

mv  apache-tomcat-7.0.x /srv/apache-tomcat/9090

修改 Server port="8006" 与 Connector port="9090"端口，不要出现重复。

<Server port="8006" shutdown="SHUTDOWN">

<Connector port="9090" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" />

<!--

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

-->

启动tomcat然后观察catalina.log日志文件，确认每个进程都正确启动。

1.7. Testing file

创建测试文件

vim webapps/ROOT/index.jsp

<%@ page contentType="text/html;charset=utf-8"%>

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<title>helloworld!</title>

</head>

<body>

<h1>

<%="It works!"%>

</h1>

<%

out.println("<h3>Hello World!</h3>");

%>

<hr />

<%=new java.util.Date()%>

</body>

</html>

使用curl命令测试，测试结果类似下面结果。

$ curl http://192.168.6.9/index.jsp

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<title>helloworld!</title>

</head>

<body>

<h1>

分别测试apache,tomcat

1.9. mod_proxy_ajp

包含虚拟主机配置文件

# vi conf/httpd.conf

# Virtual hosts

Include conf/extra/httpd-vhosts.conf

虚拟主机中配置ProxyPass,ProxyPassReverse

# vi conf/extra/httpd-vhosts.conf

<VirtualHost *:80>

ServerName netkiller.8800.org

ProxyPass /images !

ProxyPass /css !

ProxyPass /js !

ProxyPass /ajp ajp://localhost:8009/ajp

ProxyPassReverse /ajp ajp://localhost:8009/ajp

</VirtualHost>

反向代理和均衡负载模块

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

ProxyPass /admin balancer://tomcatcluster/admin lbmethod=byrequests stickysession=JSESSIONID nofailover=Off timeout=5 maxattempts=3

ProxyPassReverse /admin balancer://tomcatcluster/admin

<Proxy balancer://tomcatcluster>

BalancerMember ajp://localhost:8009 route=web1

BalancerMember ajp://localhost:10009 smax=10 route=web2

BalancerMember ajp://localhost:11009 route=web3

BalancerMember ajp://localhost:12009 smax=10 route=web4

</Proxy>

1.10. RewriteEngine 连接 Tomcat

RewriteEngine On

RewriteRule ^/(.*) ajp://localhost:8009/ajp/$1 [P]

RewriteRule ^/(.*\.(jsp|do|sevlet)) ajp://localhost:8009/ajp/$1 [P]

1.11. SSL 双向认证

首先我并不建议使用 tomcat 实现SSL双向验证，这个工作可以交给 Web 服务器完成。但有些场景可能需要，可以参考下面例子。

服务器端证书

keytool -genkey -v -alias serverKey -dname "CN=localhost" -keyalg RSA -keypass xxxxxx -keystore server.ks -storepass xxxxxx

客户端证书

keytool -genkey -v -alias clientKey -dname "CN=SomeOne" -keyalg RSA -keypass xxxxxx -keystore client.p12 -storepass xxxxxx -storetype PKCS12

keytool -export -alias clientKey -file clientKey.cer -keystore client.p12 -storepass xxxxxx -storetype PKCS12

导入客户端证书

keytool -import -v -alias clientKey -file clientKey.cer -keystore server.ks -storepass xxxxxx

如果希望在 Windows 浏览器中访问，下导入证书方式，双击 client.p12 文件，安装提示导入

配置 Tomcat ，编辑 server.xml 文件

<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"

maxThreads="1024" scheme="https" secure="true"

clientAuth="true" sslProtocol="TLS"

keystoreFile="server.ks" keystorePass="xxxxxx"

truststoreFile="server.ks " truststorePass="xxxxxx" />

2. 配置 Tomcat 服务器

2.1. server.xml

Connector

tomcat 端口默认为8080, 可以通过修改下面port项改为80端口，但不建议你这样使用80端口,tomcat 会继承root权限，这是非常危险的做法。

<Connector port="80" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" />

性能调整

<Connector port="8080" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443"

maxThreads="2048" />

<Connector port="8080" protocol="HTTP/1.1"

maxThreads="2048"

minSpareThreads="64"

maxSpareThreads="256"

acceptCount="128"

enableLookups="false"

redirectPort="8443"

debug="0"

connectionTimeout="20000"

disableUploadTimeout="true"

URIEncoding="UTF-8" />

maxThreads="4096" 最大连接数

minSpareThreads="50" 最小空闲线程

maxSpareThreads="100" 最大空闲线程

enableLookups="false" 禁止域名解析

acceptCount="15000"

connectionTimeout="30000" 超时时间

redirectPort="8443"

disableUploadTimeout="true"

URIEncoding="UTF-8" UTF-8编码

protocol="AJP/1.3" AJP协议版本

HTTPS

<Connector port="443" maxHttpHeaderSize="8192"

maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

enableLookups="false" disableUploadTimeout="true"

acceptCount="100" scheme="https" secure="true"

SSLEngine="on"

SSLCertificateFile="${catalina.base}/conf/localhost.crt"

SSLCertificateKeyFile="${catalina.base}/conf/localhost.key" />

compression

压缩传送数据

compression="on"

compressionMinSize="2048"

noCompressionUserAgents="gozilla, traviata"

compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css"

useBodyEncodingForURI

如果你的站点编码非UTF-8,去掉URIEncoding="UTF-8"使用下面选项.

useBodyEncodingForURI="true"

隐藏Tomcat版本信息

在Connector中加入server="Neo App Srv 1.0"

vim $CATALINA_HOME/conf/server.xml

<Connector port="80" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443"

maxThreads="8192"

minSpareThreads="64"

maxSpareThreads="128"

acceptCount="128"

enableLookups="false"

server="Neo App Srv 1.0"/>

# curl -I http://localhost:8080/

HTTP/1.1 400 Bad Request

Transfer-Encoding: chunked

Date: Thu, 20 Oct 2011 09:51:55 GMT

Connection: close

Server: Neo App Srv 1.0

Context

配置虚拟目录

例如我们需要这样的配置

http://www.netkiller.cn/news

http://www.netkiller.cn/member

http://www.netkiller.cn/product

实现方法

<Host name="localhost"  appBase="/www/example.com" unpackWARs="true" autoDeploy="true">

<Alias>www.example.com</Alias>

<Context path="news" docBase="www.example.com/news" reloadable="false"></Context>

<Context path="member" docBase="www.example.com/member" reloadable="false"></Context>

<Context path="product" docBase="www.example.com/product" reloadable="false"></Context>

</Host>

应用程序安全

关闭war自动部署 unpackWARs="false" autoDeploy="false"。防止被植入木马等恶意程序

关闭 reloadable="false" 也用于防止被植入木马

JSESSIONID

修改 Cookie 变量 JSESSIONID， 这个cookie 是用于维持Session关系。建议你改为PHPSESSID。

<Context path="" docBase="path/to/your" reloadable="false" sessionCookieDomain=".example.com" sessionCookiePath="/" sessionCookieName="PHPSESSID" />

2.2. tomcat-users.xml

<?xml version='1.0' encoding='utf-8'?>

<tomcat-users>

<role rolename="manager"/>

<user username="tomcat" password="QI0Ajp7" roles="manager"/>

</tomcat-users>

状态监控 http://localhost/manager/status

服务管理 http://localhost/manager/html/list

<tomcat-users>

<!--

NOTE:  By default, no user is included in the "manager-gui" role required

to operate the "/manager/html" web application.  If you wish to use this app,

you must define such a user - the username and password are arbitrary.

-->

<!--

NOTE:  The sample user and role entries below are wrapped in a comment

and thus are ignored when reading this file. Do not forget to remove

<!.. ..> that surrounds them.

-->

<!--

<role rolename="tomcat"/>

<role rolename="role1"/>

<user username="tomcat" password="tomcat" roles="tomcat"/>

<user username="both" password="tomcat" roles="tomcat,role1"/>

<user username="role1" password="tomcat" roles="role1"/>

-->

<role rolename="manager-gui"/>

<role rolename="manager-script"/>

<role rolename="manager-jmx"/>

<role rolename="manager-status"/>

<user username="tomcat" password="tomcat" roles="manager-gui,manager-script,manager-jmx,manager-status"/>

<role rolename="admin-gui"/>

<role rolename="admin-script"/>

<user username="admin" password="admin" roles="admin-gui,admin-script"/>

</tomcat-users>

2.3. context.xml

context.xml 主要用于配置 数据库连接池

开启热部署，生产环境不建议使用

<Context reloadable="true">

Resources

org.apache.catalina.webresources.Cache.getResource Unable to add the resource at [/WEB-INF/lib/netkiller.jar] to the cache because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

<Resources cachingAllowed="true" cacheMaxSize="100000" />

session cookie

<Context sessionCookieName="PHPSESSID" sessionCookieDomain=".example.com" sessionCookiePath="/">

<!-- ... -->

</Context>

2.4. logging.properties

修改日志目录

1catalina.org.apache.juli.FileHandler.level = FINE

#1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs

1catalina.org.apache.juli.FileHandler.directory = /www/logs/tomcat

1catalina.org.apache.juli.FileHandler.prefix = catalina.

2.5. catalina.properties

配置跳过扫描*.jar

tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\*.jar

context.xml

<JarScanner scanClassPath="false"/>

3. 虚拟主机配置

注意

Tomcat 8 取消了 xmlValidation="false" xmlNamespaceAware="false" 两个配置项。

appBase 是防止 war 文件的扫描目录。

3.1. 方案一

将配置写入server.xml文件

<Host name="www.example.com"  appBase="webapps"

unpackWARs="true" autoDeploy="true"

xmlValidation="false" xmlNamespaceAware="false">

<Context path="" docBase="/www/example.com/www.example.comm" debug="0" reloadable="false"/>

</Host>

<Host name="news.example.com"  appBase="webapps"

unpackWARs="true" autoDeploy="true"

xmlValidation="false" xmlNamespaceAware="false">

<Context path="" docBase="/www/example/news.example.com" debug="0" reloadable="false"/>

</Host>

3.2. 方案二

在 $CATALINA_HOME/conf/Catalina/ 下创建配置文件

vim server.xml

<Engine name="Catalina" defaultHost="neo">

<Host name="neo"    appBase="webapps"/>

<Host name="other" appBase="webapps"/>

</Engine>

Webapps Directory

mkdir $CATALINA_HOME/conf/Catalina/neo

Configuring Your Contexts

mkdir $CATALINA_HOME/conf/Catalina/neo

cp $CATALINA_HOME/conf/Catalina/localhost/manager.xml $CATALINA_HOME/conf/Catalina/neo/ROOT.xml

or

cp $CATALINA_HOME/conf/Catalina/localhost/manager.xml $CATALINA_HOME/conf/Catalina/neo

3.3. Alias 别名

别名的功能是为虚拟主机绑定多个域名

<Host name="www.example.com" debug="9" appBase="webapps"

unpackWARs="false" autoDeploy="false"

xmlValidation="false" xmlNamespaceAware="false">

<Alias>www.example.net</Alias>

<Alias>exmaple.com</Alias>

<Alias>224.25.22.70</Alias>

</Host>

3.4. access_log

<Host name="localhost" ...>

...

<Valve className="org.apache.catalina.valves.AccessLogValve"

prefix="localhost_access_log." suffix=".txt"

pattern="common"/>

...

</Host>

<Valve className"org.apache.catalina.valves.AccessLogValve"

directory="logs/access"

prefix="www.netkiller.cn.access"

suffix=".log"

pattern="%{X-Forwarded-FOR}i %a %v %U %t %m %s  %{User-Agent}i" resolveHosts="false"/>

3.5. Context 配置

<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log" suffix=".txt"/>

<Context docBase="Struts" path="/Struts" reloadable="true" source="org.eclipse.jst.jee.server:Struts"/>

</Host>

docBase如果是绝对路径就会忽略appBase="webapps"的设置。

<Context path="" docBase="/www/example.com/www.example.com/WebContent"  reloadable="false">

appBase + docBase 方案

<Host name="localhost"  appBase="/www/example.com" unpackWARs="true" autoDeploy="true">

<Alias>www.example.com</Alias>

<Context path="" docBase="www.example.com"  reloadable="false"></Context>

</Host>

3.6. 主机绑定IP地址

<Host name="223.225.22.72"  appBase="/www/netkiller.cn" unpackWARs="true" autoDeploy="true">

<Alias>www.netkiller.cn</Alias>

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

prefix="www.netkiller.cn_access_log." suffix=".log"

pattern="%h %l %u %t &quot;%r&quot; %s %b" />

<Logger className="org.apache.catalina.logger.FileLogger"

directory="logs"  prefix="web_log." suffix=".txt"  timestamp="true"/>

<Context path="" docBase="www.netkiller.cn"  reloadable="true"></Context>

</Host>

<Host name="223.225.22.73"  appBase="/www/netkiller.cn" unpackWARs="true" autoDeploy="true">

<Alias>admin.netkiller.cn</Alias>

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

prefix="admin.netkiller.cn_access_log." suffix=".log"

pattern="%h %l %u %t &quot;%r&quot; %s %b" />

<Context path="" docBase="admin.netkiller.cn"  reloadable="true" />

</Host>

4. SSI

编辑 context.xml 文件，增加 privileged="true 属性

# vim /srv/apache-tomcat/conf/context.xml

<Context privileged="true">

<!-- Default set of monitored resources -->

<WatchedResource>WEB-INF/web.xml</WatchedResource>

<!-- Uncomment this to disable session persistence across Tomcat restarts -->

<!--

<Manager pathname="" />

-->

<!-- Uncomment this to enable Comet connection tacking (provides events

on session expiration as well as webapp lifecycle) -->

<!--

<Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />

-->

</Context>

编辑 web.xml 文件，取消下面的注释

# vim /srv/apache-tomcat/conf/web.xml

<servlet>

<servlet-name>ssi</servlet-name>

<servlet-class>

org.apache.catalina.ssi.SSIServlet

</servlet-class>

<init-param>

<param-name>buffered</param-name>

<param-value>1</param-value>

</init-param>

<init-param>

<param-name>debug</param-name>

<param-value>0</param-value>

</init-param>

<init-param>

<param-name>expires</param-name>

<param-value>666</param-value>

</init-param>

<init-param>

<param-name>isVirtualWebappRelative</param-name>

<param-value>false</param-value>

</init-param>

<load-on-startup>4</load-on-startup>

</servlet>

配置需要SSI处理的文件

# vim  /srv/apache-tomcat/webapps/ROOT/WEB-INF/web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

version="3.0"

metadata-complete="true">

<display-name>Welcome to Tomcat</display-name>

<description>

Welcome to Tomcat

</description>

<servlet-mapping>

<servlet-name>ssi</servlet-name>

<url-pattern>*.shtml</url-pattern>

<url-pattern>*.html</url-pattern>

</servlet-mapping>

</web-app>

重新启动Tomcat

创建测试文件

# vim webapps/ROOT/index.html

<!--#echo var="DATE_LOCAL" -->

验证测试结果

# curl http://224.25.22.70:8080/

Tuesday, 03-Nov-2015 09:32:30 HKT

5. Logging 日志

5.1. 开启 debug 模式

又是我们需要开启debug来排查故障，只需在项目目录下创建文件 WEB-INF/classes/log4j.properties 内容如下

log4j.rootLogger=debug,console,file

重新启动tomcat将进入Debug模式，你将看到大量的调试信息。

5.2. 切割 catalina.out 日志

1) log4j.properties: Add the console to the root logger

log4j.rootLogger = INFO, CATALINA, CONSOLE

2) log4j.properties: Change the DailyRollingFileAppender to:

log4j.appender.CATALINA=org.apache.log4j.rolling.RollingFileAppender

log4j.appender.CATALINA.RollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy

log4j.appender.CATALINA.RollingPolicy.FileNamePattern=${catalina.base}/logs/catalina.%d{yyyy-MM-dd}.log

PHP

过程 4.1. 安装PHP

1. 第一步

cd /usr/local/src

wget http://cn2.php.net/get/php-5.3.0.tar.bz2/from/cn.php.net/mirror

tar jxvf php-5.3.0.tar.bz2

cd php-5.3.0

2. 第二步

./configure --prefix=/usr/local/php-5.3.0 \

--with-config-file-path=/usr/local/php-5.3.0/etc \

--with-apxs2=/usr/local/apache/bin/apxs \

--with-curl \

--with-gd \

--with-ldap \

--with-snmp \

--enable-zip \

--enable-exif \

--with-libxml-dir \

--with-mysql \

--with-mysqli \

--with-pdo-mysql \

--with-pdo-pgsql

make

make test

make install

1. 建立符号连接

ln -s /usr/local/php-5.3.0 /usr/local/php

2. php.ini

cp php.ini-dist /usr/local/php/etc/php.ini

3. conf/httpd.conf

AddType application/x-httpd-php .php .phtml

AddType application/x-httpd-php-source .phps

reload apache

3. 最后一步

phpinfo() 测试文件复杂到apache目录

例 4.1. index.php

<?php phpinfo(); ?>

--with-snmp

redhat as4 启用 --with-snmp 需要安装下面包

rpm -i elfutils-libelf-devel-0.97.1-3.i386.rpm

rpm -i elfutils-devel-0.97.1-3.i386.rpm

ServerLimit 默认是16，它决定系统最多启动几个httpd进程。

ThreadLimit 默认是64，

ThreadsPerChild* ServerLimit=系统支持的最大并发。

MaxClients<ThreadsPerChild* ServerLimit，MaxClients如果大于400将被限制在400.

400只是理论最大并发，实际并发就是MaxClients的值。

理论并发有什么用我不知道。

指令说明：

StartServers：设置服务器启动时建立的子进程数量。因为子进程数量动态的取决于负载的轻重,所有一般没有必要调整这个参数。

ServerLimit：服务器允许配置的进程数上限。只有在你需要将MaxClients和ThreadsPerChild设置成需要超过默认值16个子进程的时候才需要使用这个指令。不要将该指令的值设置的比MaxClients 和ThreadsPerChild需要的子进程数量高。修改此指令的值必须完全停止服务后再启动才能生效，以restart方式重启动将不会生效。

ThreadLimit：设置每个子进程可配置的线程数ThreadsPerChild上限,该指令的值应当和ThreadsPerChild可能达到的最大值保持一致。修改此指令的值必须完全停止服务后再启动才能生效，以restart方式重启动将不会生效。

MaxClients：用于伺服客户端请求的最大接入请求数量（最大线程数）。任何超过MaxClients限制的请求都将进入等候队列。默认值是"400"，16 (ServerLimit)乘以25(ThreadsPerChild)的结果。因此要增加MaxClients的时候，你必须同时增加 ServerLimit的值。笔者建议将初始值设为(以Mb为单位的最大物理内存/2),然后根据负载情况进行动态调整。比如一台4G内存的机器，那么初始值就是4000/2=2000。

MinSpareThreads：最小空闲线程数,默认值是"75"。这个MPM将基于整个服务器监视空闲线程数。如果服务器中总的空闲线程数太少，子进程将产生新的空闲线程。

MaxSpareThreads：设置最大空闲线程数。默认值是"250"。这个MPM将基于整个服务器监视空闲线程数。如果服务器中总的空闲线程数太多，子进程将杀死多余的空闲线程。MaxSpareThreads的取值范围是有限制的。Apache将按照如下限制自动修正你设置的值：worker要求其大于等于 MinSpareThreads加上ThreadsPerChild的和。

ThreadsPerChild：每个子进程建立的线程数。默认值是25。子进程在启动时建立这些线程后就不再建立新的线程了。每个子进程所拥有的所有线程的总数要足够大，以便可以处理可能的请求高峰。

MaxRequestsPerChild：设置每个子进程在其生存期内允许伺服的最大请求数量。到达MaxRequestsPerChild的限制后，子进程将会结束。如果MaxRequestsPerChild为"0"，子进程将永远不会结束。将MaxRequestsPerChild设置成非零值有两个好处：可以防止(偶然的)内存泄漏无限进行而耗尽内存；

给进程一个有限寿命，从而有助于当服务器负载减轻的时候减少活动进程的数量。

如果设置为非零值，笔者建议设为10000-30000之间的一个值。

公式：

ThreadLimit >= ThreadsPerChild

MaxClients <= ServerLimit * ThreadsPerChild 必须是ThreadsPerChild的倍数

MaxSpareThreads >= MinSpareThreads+ThreadsPerChild

rotatelogs - Piped logging program to rotate Apache logs

rotatelogs是一个配合Apache管道日志功能使用的简单程序。举例：

rotatelogs logfile [ rotationtime [ offset ]] | [ filesizeM ]

选项

logfile

它加上基准名就是日志文件名。如果logfile中包含’%'，则它会被视为用于的strftime(3)的格式字串；否则，它会被自动加上以秒为单位的.nnnnnnnnnn后缀。这两种格式都表示新的日志开始使用的时间。

rotationtime

日志文件回卷的以秒为单位的间隔时间

offset

相对于UTC的时差的分钟数。如果省略，则假定为0，并使用UTC时间。比如，要指定UTC时差为-5小时的地区的当地时间，则此参数应为-300。

filesizeM

指定回卷时以兆字节为单位的后缀字母M的文件大小，而不是指定回卷时间或时差。

下列日志文件格式字串可以为所有的strftime(3)实现所支持，见各种扩展库对应的strftime(3)的手册。

%A 星期名全称(本地的)

%a 3个字符的星期名(本地的)

%B 月份名的全称(本地的)

%b 3个字符的月份名(本地的)

%c 日期和时间(本地的)

%d 2位数的一个月中的日期数

%H 2位数的小时数(24小时制)

%I 2位数的小时数(12小时制)

%j 3位数的一年中的日期数

%M 2位数的分钟数

%m 2位数的月份数

%p am/pm 12小时制的上下午(本地的)

%S 2位数的秒数

%U 2位数的一年中的星期数(星期天为一周的第一天)

%W 2位数的一年中的星期数(星期一为一周的第一天)

%w 1位数的星期几(星期天为一周的第一天)

%X 时间 (本地的)

%x 日期 (本地的)

%Y 4位数的年份

CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common

此配置会建立文件"/var/logs/logfile.nnnn"，其中的nnnn是名义上的日志启动时的系统时间(此时间总是滚动时间的倍数，可以用于cron脚本的同步)。在滚动时间到达时(在此例中是24小时以后)，会产生一个新的日志。

CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common

此配置会在日志文件大小增长到5兆字节时滚动该日志。

ErrorLog "|bin/rotatelogs /var/logs/errorlog.%Y-%m-%d-%H_%M_%S 5M"

此配置会在错误日志大小增长到5兆字节时滚动该日志，日志文件名后缀会按照如下格式创建：errorlog.YYYY-mm-dd-HH_MM_SS

https://www.sit.auckland.ac.nz/Logging_to_syslog_with_Apache

Logging to syslog with Apache

First you will need to install syslog-ng. This is the logging server that will send the log data to the syslog box.

apt-get update && apt-get install syslog-ng

syslog-ng uses a socket device to accept data from apache or whatever program is creating the logs.

Use the configuration here: Syslog-ng default config.

The first part indicates what the socket will be called and where it will live. The second part tells syslog-ng where to send the collected data. The restart syslog-ng (/etc/init.d/syslog-ng restart)l.

Configure apache's logging

Add these directives to send apache's logs via a socket to syslog

CustomLog "|/usr/bin/logger -s -t 'monitor.cs.auckland.ac.nz' -p info -u /var/log/apache_log.socket" Combined

ErrorLog "|/usr/bin/logger -s -t 'monitor.cs.auckland.ac.nz' -p err -u /var/log/apache_log.socket"

Apache will then use the logger program to send data to syslog. /var/log/apache_log.socket refers to the device that syslog-ng has created. Data sent to this device is sent over the network to the main syslog box.

Troubleshooting

It seems that apache 2.0.54-5 does not like logging to a file and to a process at the same time. In this case log entries will become re-ordered or missed out. You can use the test scripts below to check if this is happening.

Testing

Here are some useful scripts that can help with testing to make sure the logging is working as expected.

You can simulate http accesses using lynx with this command:

watch lynx -source http://monitor.cs.auckland.ac.nz/

Which will make a http request every two seconds. Or, for a better test:

for i in `seq 1 100`; do lynx -source http://monitor.cs.auckland.ac.nz/$i;sleep 3;done

The result of this test is a sequence of log entires from 1 to 100. If entries are missing or in the wrong order, you know there is a problem.

找到 server.modules

删除 mod_fastcgi 前的注释

跟据你的需求修改下面定义

server.document-root = "/usr/local/lighttpd/htdocs/"

server.errorlog = "/usr/local/lighttpd/logs/lighttpd.error.log"

accesslog.filename = "/usr/local/lighttpd/logs/access.log"

注释 $HTTP["url"]

#$HTTP["url"] =~ "\.pdf$" {

#  server.range-requests = "disable"

#}

5. 运行lighttpd

"/images" => "/home/neo/workspace/Development/photography/application/photography/images",

"/stylesheet" => "/home/neo/workspace/Development/photography/application/photography/stylesheet"

)

}

3.6. auth

enable auth

$ sudo lighttpd-enable-mod auth

/etc/lighttpd/conf-enabled/05-auth.conf

$ sudo vim  conf-enabled/05-auth.conf

auth.backend = "plain"

auth.backend.plain.userfile = "/etc/lighttpd/.secret"

auth.require = ( "/tmp/" =>

(

"method" => "basic",

"realm" => "Password protected area",

"require" => "user=neo"

)

)

create a passwd file

$ sudo vim .secret

neo:chen

$ sudo chmod 400 .secret

$ sudo chown www-data /etc/lighttpd/.secret

$ sudo /etc/init.d/lighttpd reload

3.7. compress

创建cache目录

mkdir -p /var/cache/lighttpd/compress

配置lighttpd.conf文件

找到server.modules列表,去掉"mod_compress"注释,再打开compress module的注释

#### compress module

compress.cache-dir         = "/var/lighttpd/cache/compress/"

compress.filetype          = ("text/plain", "text/html")

Compressing Dynamic Content

php.ini

zlib.output_compression = On

zlib.output_handler = On

最后使用telnet测试

telnet www.bg7nyt.cn 80

GET /index.html HTTP/1.0

Host: 10.10.100.183

Accept-Encoding: gzip,deflate

看到乱码输出,而非HTML,表示配置成功.

例 5.2. lighttpd compress

$HTTP["host"] =~ "www\.example\.com$" {

compress.cache-dir = "/www/compress/"

compress.filetype = ("text/plain", "text/html", "application/x-javascript", "text/css", "application/javascript", "text/javascript")

$HTTP["url"] =~ "(\.png|\.css|\.js|\.jpg|\.gif)$" {

expire.url = (""=>"access 30 seconds")

}

}

3.8. expire

<access|modification> <number> <years|months|days|hours|minutes|seconds>

expire.url = ( "/images/" => "access 1 hours" )

Example to include all sub-directories:

$HTTP["url"] =~ "^/images/" {

expire.url = ( "" => "access 1 hours" )

}

例 5.3. lighttpd expire

$HTTP["host"] =~ "www\.example\.com$" {

$HTTP["url"] =~ "(\.png|\.css|\.js|\.jpg|\.gif)$" {

expire.url = (""=>"access 30 seconds")

}

}

3.9. status

$ sudo lighty-enable-mod status

$ sudo /etc/init.d/lighttpd force-reload

3.10. setenv

$HTTP["url"] =~ "^/(.*)" {

setenv.add-response-header = ( "Cache-Control" => "no-store, no-cache, must-revalidate, post-check=0, pre-check=0, max-age=-1" )

}

$HTTP["url"] =~ ".swf" {

setenv.add-response-header  = ("Pragma" =>"no-cache","Expires" => "-1")

}

$HTTP["url"] =~ ".swf" {

setenv.add-response-header  = ("Cache-Control" =>"max-age=0")

}

$HTTP["url"] =~ ".html" {

setenv.add-response-header  = ("Cache-Control" =>"s-maxage=3600")

}

$HTTP["url"] =~ ".css" {

setenv.add-response-header = (

"Content-Encoding" => "gzip"

)

}

Automatic Decompression

$HTTP["url"] =~ "(README|ChangeLog|\.txt)\.gz$" {

setenv.add-response-header  = ( "Content-Encoding" => "gzip")

mimetype.assign = ("" => "text/plain" )

}

3. resin.conf

3.1. Maximum number of threads

Maximum number of threads.

<thread-max>4096</thread-max>

thread-max数值需要使用ab命令做压力测试，逐步调整。

3.2. Configures the keepalive

<!-- Configures the keepalive -->

<keepalive-max>128</keepalive-max>

<keepalive-timeout>15s</keepalive-timeout>

3.3. ssl

<http address="*" port="443">

<openssl>

<certificate-file>/srv/keys/example.com/star.example.com.crt</certificate-file>

<certificate-key-file>/srv/keys/example.com/star.example.com.key</certificate-key-file>

<password>4fff74da-aea4-a9fc-4b5f-e6d497588726</password>

</openssl>

</http>

自颁发证书，首先是使用keytool工具安装证书

生成证书：

keytool –genkeypair –keyalg RSA –keysize 2048 SHA1withRSA –validity 3650  -alias neo –keystore server.keystore –storepass password –dname "CN=www.example.com, OU=test, O=example.com, L=SZ, ST=GD, C=CN"

导出证书

-keytool –exportcert –alias neo –keystore server.keystore –storepass password  –file server.cer –rfc

打印证书

Keytool -printcert –file server.cer

导出证书签发申请

Keytool –certreg –aias neo –keystore server.keystore –storepass password –file ins.csr –v

导入证书

Keytool –importcert –trustcacerts –alias neo –file server.cer –keystore server.keystore –storepass password

查看数字证书

Keytool -list

当成功的导入了证书以后就要容器中进行配置才可以使用

首先是要把证书中的那个 server.keystore 和 server.cer这两个文件放入到Resin服务器的keys这个文件夹中 如果没有的话 就手动的建立这个文件夹

然后去 config 文件夹下配置你的配置文件

我在resin 这个容器中的配置如下

<http address="*" port="443">

<jsse-ssl>

<key-store-file>keys/server.keystore</key-store-file>

<password>password</password>

</jsse-ssl>

</http>

1.1. open files

对于linux系统，所有设备都以映射为设备文件的方式存在，包括硬件（键盘，鼠标，打印机，显示器，串口，并口，USB，硬盘，内存，网卡，声卡，显卡，等等....），还有软件(管道，socket)，访问这些资源，就相当与打开一个文件，

所以"open files"文件数限制很重要，默认值根本不能满足我们。

查看文件打开数

$ cat /proc/sys/fs/file-nr

4. Varnish Configuration Language - VCL

Varnish配置文件VCL中的函数详解

内置的例程

vcl_recv

有请求到达后成功接收并分析时被调用，一般以以下几个关键字结束。

error code [reason] 返回code给客户端，并放弃处理该请求

pass 进入pass模式，把控制权交给vcl_pass

pipe 进入pipe模式，把控制权交给vcl_pipe

lookup 在缓存里查找被请求的对象，根据查找结果把控制权交给vcl_hit或vcl_miss

vcl_pipe

进入pipe模式时被调用。请求被直接发送到backend，后端和客户端之间的后继数据不进行处理，只是简单传递，直到一方关闭连接。一般以以下几个关键字结束。

error code [reason]

pipe

vcl_pass

进入pass模式时被调用。请求被送到后端，后端应答数据送给客户端，但不进入缓存。同一连接的后继请求正常处理。一般以以下几个关键字结束。

error code [reason]

pass

vcl_hash

目前不使用

vcl_hit

在lookup以后如果在cache中找到请求的内容事调用。一般以以下几个关键字结束。

error code [reason]

pass

deliver 将找到的内容发送给客户端，把控制权交给vcl_deliver.

vcl_miss

lookup后但没有找到缓存内容时调用，可以用于判断是否需要从后端服务器取内容。一般以以下几个关键字结束。

error code [reason]

pass

fetch 从后端取得请求的内容，把控制权交给vcl_fetch.

vcl_fetch

从后端取得内容后调用。一般以以下几个关键字结束。

error code [reason]

pass

insert 将取到的内容插入缓存，然后发送给客户端，把控制权交给vcl_deliver

vcl_deliver

缓存内容发动给客户端前调用。一般以以下几个关键字结束。

error code [reason]

deliver 内容发送给客户端

vcl_timeout

在缓存内容到期前调用。一般以以下几个关键字结束。

fetch 从后端取得该内容

discard 丢弃该内容

vcl_discard

由于到期或者空间不足而丢弃缓存内容时调用。一般以以下几个关键字结束。

discard 丢弃

keep 继续保留在缓存里

如果这些内置例程没有被定义，则执行缺省动作

一些内置的变量

now 当前时间，标准时间点（1970？）到现在的秒数

backend.host 后端的IP或主机名

backend.port 后端的服务名或端口

请求到达后有效的变量

client.ip 客户端IP

server.ip 服务端IP

req.request 请求类型，比如GET或者HEAD或者POST

req.url 请求的URL

req.proto 请求的HTTP版本号

req.backend 请求对应的后端

req.http.header 对应的HTTP头

往后段的请求时有效的变量

bereq.request 比如GET或HEAD

bereq.url URL

bereq.proto 协议版本

bereq.http.header HTTP头

从cache或后端取到内容后有效的变量

obj.proto HTTP协议版本

obj.status HTTP状态代码

obj.response HTTP状态信息

obj.valid 是否有效的HTTP应答

obj.cacheable 是否可以缓存的内容，也就是说如果HTTP返回是200、203、300、301、302、404、410并且有非0的生存期，则为可缓存

obj.ttl 生存期，秒

obj.lastuse 上一次请求到现在间隔秒数

对客户端应答时有效的变量

resp.proto response的HTTP版本

resp.status 回给客户端的HTTP状态代码

resp.response 回给客户端的HTTP状态信息

resp.http.header HTTP头

4.1. unset / set

sub vcl_deliver {

##### Remove some headers

unset resp.http.Server;

unset resp.http.X-Powered-By;

unset resp.http.X-Varnish;

unset resp.http.Via;

###

if (obj.hits > 0){

set resp.http.X-Cache = "cdn cache server v2.0";

}else{

set resp.http.X-Cache = "MISS ";

}

return (deliver);
