虚拟机搭建
1.每个主机修改hostname，node1,node2,node3<br>vi /etc/hostname<br>重启让主机名生效
2.修改每个主机的hosts<br>vi /etc/hosts<br>ip1 node1<br>ip2 node2<br>ip3 node3<br>
3.每个节点的Cookie一致，在node1上通过远程复制方式<br>scp /var/lib/rabbitmq/.erlang.cookie root@node2:/var/lib/rabbitmq/.erlang.cookie<br>scp /var/lib/rabbitmq/.erlang.cookie root@node3:/var/lib/rabbitmq/.erlang.cookie<br>
4.重启每个机器RabbitMQ服务<br>rabbitmq-server -detached
5.node2加入node1<br>rabbitmqctl stop_app<br>rabbitmqctl reset<br>rabbitmqctl join_cluster rabbit@node1<br>rabbitmqctl start_app<br><br>同理node3加入node2
6.查看集群状态<br>rabbitmqctl cluster_status
7.需要重新设置用户<br>rabbitmqctl add_user admin 123<br>rabbitmqctl set_user_tags admin administrators<br>rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"<br>
附：解除集群状态<br>node2上执行：<br>rabbitmqctl stop_app<br>rabbitmqctl reset<br>rabbitmqctl start_app<br>rabbitmqctl cluster_status<br>node1上执行：<br>rabbitmqctl forget）cluster_node rabbit@node2<br>
