1，修改redis.conf

设置redis后台启动

daemonize yes

2，编写脚本

vi /etc/init.d/redis

#!/bin/sh
#chkconfig: 2345 10 90

1，$1：执行命令的第一个参数，例如/etc/init.d/redis start，start就是第一个参数
2，${0}：文件所在路径，例如文件所在路径为/etc/init.d/redis，那么${0}的值就是该路径
3，脚本要放在 /etc/init.d/ 下，不然执行server redis ... 的命令会提示找不到redis

3，添加执行权限

chmod +x /etc/init.d/redis

service redis start
service redis stop<pre name="code" class="plain">service redis restart

4，设置开机启动

chkconfig redis on

chkconfig --add redis
