redis自定义使用start|stop|restart来停止和启动redis服务，redisrestart

我的redis的目录是在/usr/local/redis/redis

启动要在 /usr/local/redis/redis目录操作start  停止:stop 重启：restart

下面是需要在/etc/init.d 目录下面创建一个redis文件，touch redis ，然后修改redis的对外权限访问，chmod a+x /etc/init.d/redis

下面是提供start|stop|restart 服务的脚本，拷贝到redis文件里面

 #!/src/bash
#chkconfig: 2345 55 25
#description: Starts,stops and restart the redis-server
#Ver:1.1
