rabbitmq三节点搭建

rabbitmq三节点搭建（p_cluster1 p_cluster2 p_cluster3）

1. 安装erlang（p_cluster1 p_cluster2 p_cluster3）
   curl -s https://packagecloud.io/install/repositories/
   rabbitmq/erlang/script.rpm.sh | sudo bash
   yum install erlang
2. 安装rabbitmq（p_cluster1 p_cluster2 p_cluster3）
   wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.1/rabbitmq-server-3.8.1-1.el7.noarch.rpm
   yum -y install socat
   rpm -ivh rabbitmq-server-3.8.1-1.el7.noarch.rpm
3. 修改主机hosts文件
   vim /etc/hosts
   192.168.2.215 p_cluster1
   192.168.2.216 p_cluster2
   192.168.2.217 p_cluster3
   scp /etc/hosts p_cluster2:/etc/
   scp /etc/hosts p_cluster3:/etc/
   导入rabbitmq的管理界面
   rabbitmq-plugins enable rabbitmq_management
4. 设置erlang

scp /var/lib/rabbitmq/.erlang.cookie p_cluster2:/var/lib/rabbitmq/
scp /var/lib/rabbitmq/.erlang.cookie p_cluster3:/var/lib/rabbitmq/
5. 重启p
