## 完整步骤

Tips： 为了保证编译一次成功，可以将『遇到的问题』部分中须安装的依赖提前安装好。

### 获取代码并编译

```bash
$ cd ~/workspace/git
$ git clone git@github.com:git/git.git
$ cd git
$ git checkout v2.11.0 ; 当前最新版
$ git checkout -b v2.11 ; 创建新分支
$ make prefix=/usr all doc info
$ sudo mv ../git /opt
```
### 卸载旧版 Git

- `yum remove git`

### 将编译好的最新版的目录添加到环境变量

```
file: ~/.bashrc

PATH=/opt/git:$PATH
export PATH
```
- `. ~/.bashrc`  //使环境变量生效

```
[rainstorm@localhost blog]$ git --version
git version 2.11.0
```
### 添加 man-page

```
添加以下代码到 /etc/man_db.conf 最后一行
MANDATORY_MANPATH                       /opt/git/Documentation

$ cd /opt/git/Documentation
$ mkdir man1 man5 man7
$ mv *.1 man1
$ mv *.5 man5
$ mv *.7 man7

$ man git
```

## 后遗症

1. 在运行命令时可能会出现 `no such file...` 这类的问题，只要把 `/opt/git/` 目录下相应的文件复制到错误指定的位置即可

```
/usr/libexec/git-core/git-sh-setup: line 343: cd: .git: No such file or directory

$ sudo mkdir /usr/libexec/git-core
$ sudo cp /opt/git/git-sh-setup /usr/libexec/git-core
```

## 遇到的问题
