3台服务器Redis高可用哨兵模式实现(2)

redis-sentinel启停脚本示例：

#!/bin/bash
#
# redis-sentinel - this script starts and stops the redis-server sentinel daemon

# config:      /usr/local/redis/etc/sentinel.conf
# config:      /etc/sysconfig/redis
# pidfile:     /usr/local/redis/var/redis-sentinel.pid

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
