redis 启动脚本

在Linux系统中可以通过初始化脚本启动Redis，使得Redis能随系统自动运行，在生产环境中推荐使用此方法运行Redis

redis 启动脚本 

#!/bin/sh
#chkconfig: 2345 10 90
#description: Startup and stop script for Redis

#$1：执行命令的第一个参数，例如/etc/init.d/redis start，start就是第一个参数
#${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
#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
# 使用说明 service redis stop/start/restart
PATH=/usr/local/bin:/sbin:/usr/bin:/bin

# 支持多个port
