1.修改3台的主机名称,也可以不改

vi /etc/hostname

2.配置各个节点的host文件,让各节点都能识别对方

vi /etc/hosts

192.168.3.132 host-rabbitmq

192.168.3.133 host-rabbitmq2

192.168.3.134 host-rabbitmq3

3.以确保各个节点的cookie文件使用的同一个值

  在node1上执行远程命令

scp /var/lib/rabbitmq/.erlang.cookie root@host-rabbitmq2:/var/lib/rabbitmq/.erlang.cookie

scp /var/lib/rabbitmq/.erlang.cookie root@host-rabbitmq3:/var/lib/rabbitmq/.erlang.cookie

 4.重启RabbitMQ服务，顺带启动Erlang虚拟机和RabbitMQ应用服务(在三个节点上执行)

rabbitmq-server -detached

5.在2节点上执行

rabbitmqctl stop_app #只关闭Rabbitmq服务

rabbitmqctl reset

rabbitmqctl join_cluster rabbit@host-rabbitmq

rabbitmqctl start_app #只启动应用服务

6.在3节点执行

rabbitmqctl stop_app #只关闭Rabbitmq服务

rabbitmqctl reset

rabbitmqctl join_cluster rabbit@host-rabbitmq2

rabbitmqctl start_app #只启动应用服务

7.集群状态

rabbitmqctl cluster_status

8.解除集群节点(node2和node3机器分别执行)

rabbitmqctl stop_app

rabbitmqctl reset

rabbitmqctl start_app

rabbitmqctl cluster_status

rabbitmqctl forget_cluster_node_rabbit@host-rabbitmq2(node1机器上执行)
