rabbitmq主备模式部署

192.168.15.240 主机名rabbitmq240
192.168.15.241 主机名rabbitmq241
vip: 192.168.15.1
vip: 192.168.15.2

1.两台机器安装
yum -y install erlang.x86_64
ln -s /usr/local/erlang/bin/erl /usr/bin/erl
ln -s /usr/local/erlang/bin/epmd /usr/bin/epmd
yum -y install rabbitmq.x86_64
2.配置主机名，
echo "192.168.15.240 rabbitmq240" >> /etc/hosts
echo "192.168.15.241 rabbitmq241" >> /etc/hosts
3.master 192.168.15.240操作
/usr/local/rabbitmq/sbin/rabbitmq-server -detached
生成文件：~/.erlang.cookie
        cat ~/.erlang.cookie
在master上启动代理：python -m SimpleHTTPServer 7890，备机上执行：wget http://192.168.15.240:7890/.erlang.cookie获取文件
确保master和slave该文件一致，否则加不进集群。
权限也要一致
chmod 400 .erlang.cookie
4.在slave上 192.168.15.241
/usr/local/rabbitmq/sbin/rabbitmq-server -detached
/usr/local/rabbitmq/sbin/rabbitmqctl stop_app
/usr/local/rabbitmq/sbin/rabbitmqctl join_cluster rabbit@rabbitmq240
/usr/local/rabbitmq/sbin/rabbitmqctl start_app

常用命令：
关闭启动mq
/etc/init.d/rabbitmq-server stop
/etc/init.d/rabbitmq-server start
检测集群状态
/usr/local/rabbitmq/sbin/rabbitmqctl cluster_status
删除节点
/usr/local/rabbitmq/sbin/rabbitmqctl forget_cluster_node  rabbit@rabbitmq241

vip配置如下：
/etc/rc.d/init.d/realserver

#!/bin/bash # chkconfig: - 95 50 # description: Config realserver lo and apply noarp  VIPS="192.168.15.1 192.168.15.1" OLD_VIPS=`/sbin/ip a show dev lo |grep 'global'|awk '{print $4}'` . /etc/rc.d/init.d/functions start() {       for VIP in $VIPS        do       ifconfig lo:`echo $VIP|awk -F.

执行sh checkvip.sh

realserver_num=$(/sbin/ip a |grep inet |grep lo: |grep brd |wc -l) if [ ! -f /etc/init.d/realserver ];then         exit fi if [ ${realserver_num} -lt 3 ];then         /etc/init.d/realserver restart fi

设置定时任务
