11.2.3 Redis的启动停止

11.2.3  Redis的启动停止

Redis安装配置完成后，启动过程非常简单，执行命令/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf即可。停止Redis的最简单的方法是在启动实例的session中，直接使用Control-C命令。当然还可以通过客户端来停止服务，如可以用shutdown来停止Redis实例，具体命令为src/redis-cli shutdown。

下面是一个Shell脚本（供参考），用于管理Redis（启动、停止、重启）。为其赋予可执行权限，即可像其他服务一样使用。

#!/bin/sh

# redis - this script starts and stops the redis-server daemon
