I installed the rabbitmq on the VM1(controller1), VM2(controller2), VM2(controller3), and I all did the cluster for the three nodes for rabbitmq:

I can not access the rabbitmq website :xxx.xxx.xxx.xxx:15672 in the google, and I also test the rabbitmq cluster_status by below:

[root@controller1 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@controller1 ...
Error: unable to connect to node rabbit@controller1: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@controller1]

rabbit@controller1:
  * connected to epmd (port 4369) on controller1
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on controller1
  * suggestion: start the node

current node details:
- node name: 'rabbitmq-cli-72@controller1'
- home dir: /var/lib/rabbitmq
- cookie hash: ddoRf9c8dnoMOEr3jgrxqQ==

And I list the rabbitmq-plugins:

[root@controller1 ~]#  /usr/lib/rabbitmq/bin/rabbitmq-plugins list
