Posted 2021-05-21 西风h

shell脚本安装三哨兵模式集群，一主二从。

脚本如下

#!/bin/bash
echo "本地yum源是否配置完毕，是请忽略，否请按CTRL+C退出！"
sleep 3
echo "自动化安装redis-5.0.9版本,一主二从三哨兵集群："
read -p "请根据实际数据挂载盘输入redis哨兵集群安装的主目录(譬如/wls或是/data)：" maindir
ip addr
echo "redis5哨兵集群配置："
read -p "请输入本地内网IP地址(参考上面输出信息,非127.0.0.1)：" ip
read -p "请输入 master ip : " masterip
read -p "请输入 slave1 ip : " slave1ip
read -p "请输入 slave2 ip : " slave2ip
read -p "请输入加密密码：" password
read -p "请输入当前节点是 master 或者 slave：" kind
