Redis 快速脚本

需求：

1.可以启动、关闭、重启redis

启动：当redis没有运行的时候直接启动并输出启动成功，运行了就输出已经启动，避免重复进程

关闭：如果进程存在就关闭并输出已经关闭，没有进程则直接输出redis没有启动

重启：当进程存在就先执行关闭再启动，并输出重启成功，如果进程不存在直接执行启动

2.可以查看redis进程

3.可以登录redis

4.可以查看redis日志

5.由于redis是多端口实例，因此需要能够实现指定一个端口就能够启动这个端口的进程**

代码如下：

#!/bin/bash
#redis控制脚本
redis_port=$2
redis_name="redis_${redis_port}"
redis_home=/data/redis_cluster/${redis_name}
redis_conf=${redis_home}/conf/${redis_name}.conf
redis_host=`ifconfig ens33 | awk 'NR==2{print $2}'`
redis_pass=$3
red="\e[031m"
green="\e[032m"
yellow="\e[033m"
black="\e[0m"
