--- date: 2022-02-21 --- # 命令请求的过程 Redis 服务器负责与多个客户端建立网络连接，处理客户端发送的命令请求，在数据库中保存客户端执行命令所产生的数据。 Redis 服务器中的 serverCron 函数默认每隔 100 毫秒执行一次，负责管理服务器的资源，并保持服务器自身的良好运转。 整体流程都在下面的两张图里了~ ![](http://yano.oss-cn-beijing.aliyuncs.com/blog/20220224191634.png?x-oss-process=style/yano) ![](http://yano.oss-cn-beijing.aliyuncs.com/blog/20220224191704.png?x-oss-process=style/yano) # 参考链接 -
