shell一键脚本docker部署分布式rabbitmq集群

首先次脚本执行的前提条件是各服务器之间打通免密登录 (注意 这里不考虑安全只实现功能 各服务器最好同在一个内网)
1.在其中一台服务器创建文件 ip.txt IP配置文件
备注: IP 用户名 密码 端口 (注意空格)
内容如下:
192.168.1.90 root 123456 22
192.168.1.92 root 123456 22
192.168.1.91 root 123456 22
192.168.1.93 root 123456 22
192.168.1.97 root 123456 22
192.168.1.98 root 123456 22
2.只需要在其中一台服务器执行这个脚本即可 此脚本须与 ip.txt IP配置文件同目录
rabbitmq-install.sh 脚本内容如下:
#!/bin/bash
ip=’’
user=’’
pwd=’’
j=1
logth=install.log
iso=‘rabbitmq:3-management’
cookie=‘rabbitcookie’
hport=15672
port1=5672
port2=4369
port3=25672
name1=rabbit1
rabbitmq=/home/web/rabbitmq
host=/root/hosts
#获取脚本参数
if [ ! -f ip.txt ];then
echo ‘请在脚本install.sh当前目录创建ip.txt文件内容一个IP对应一个用户名一个密码一个端口 格式为 IP username password port 中间空格隔开’
exit
fi
iparr=(cat ip.txt)
count=${#iparr[*]}
if [ $(($count%4)) -ne 0 ];then
echo ‘请确保ip.txt文件内容一个IP对应一个用户名一个密码一个端口 格式为 IP username password port 中间空格隔开’
exit
fi
