1、安装RabbitMQ-server
[iyunv@controller1 ~]# yum install -y erlang rabbitmq-server
[iyunv@controller1 ~]# systemctl start rabbitmq-server.service
[iyunv@controller1 ~]# systemctl enable rabbitmq-server.service
[iyunv@controller1 ~]# systemctl status rabbitmq-server.service
[iyunv@controller1 ~]# systemctl list-unit-files | grep rabbitmq
rabbitmq-server.service                       enabled
以上三个节点同时进行

[iyunv@controller1 ~]# rabbitmqctl add_user openstack zoomtech
Creating user "openstack" ...
[iyunv@controller1 ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/" ...

[iyunv@controller1 ~]# /usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent
The following plugins have been enabled:
  webmachine
  rabbitmq_web_dispatch
  rabbitmq_management_agent
  rabbitmq_management
  mochiweb
  amqp_client
Applying plugin configuration to rabbit@controller1... failed.
* Could not contact node rabbit@controller1.
   Changes will take effect at broker restart.
* Options: --online  - fail if broker cannot be contacted.
            --offline - do not try to contact broker.
[iyunv@controller1 ~]# systemctl restart rabbitmq-server.service
[iyunv@controller1 ~]# systemctl status rabbitmq-server.service

新增一个用户，在三个节点中操作
[iyunv@controller1 ~]# rabbitmqctl add_user mqadmin mqadmin
Creating user "mqadmin" ...
[iyunv@controller1 ~]# rabbitmqctl set_permissions -p / mqadmin ".*" ".*" ".*"
Setting permissions for user "mqadmin" in vhost "/" ...
[iyunv@controller1 ~]# rabbitmqctl status

复制.erlang.coolie到controller2和controller3
[iyunv@controller1 ~]# scp /var/lib/rabbitmq/.erlang.cookie controller2:/var/lib/rabbitmq/.erlang.cookie
[iyunv@controller1 ~]#
[iyunv@controller1 ~]# scp /var/lib/rabbitmq/.erlang.cookie controller3:/var/lib/rabbitmq/.erlang.cookie

将controller2加入到controller1集群中
[iyunv@controller2 ~]# systemctl restart rabbitmq-server.service

[iyunv@controller2 ~]# rabbitmqctl stop_app
Stopping node rabbit@controller2 ...

[iyunv@controller2 ~]# rabbitmqctl join_cluster --ram rabbit@controller1
Clustering node rabbit@controller2 with rabbit@controller1 ...

[iyunv@controller2 ~]# rabbitmqctl start_app
Starting node rabbit@controller2 ...

将controller3加入到controller1集群中
[iyunv@controller3 ~]# systemctl restart rabbitmq-server.service

[iyunv@controller3 ~]# rabbitmqctl stop_app
Stopping node rabbit@controller3 ...

[iyunv@controller3 ~]# rabbitmqctl join_cluster --ram rabbit@controller1
Clustering node rabbit@controller3 with rabbit@controller1 ...

在Controller1上查看集群状态
[iyunv@controller1 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@controller1 ...
[{nodes,[{disc,[rabbit@controller1]},
         {ram,[rabbit@controller3,rabbit@controller2]}]},
{running_nodes,[rabbit@controller3,rabbit@controller2,rabbit@controller1]},
{cluster_name,<<"rabbit@controller1">>},
{partitions,[]},
{alarms,[{rabbit@controller3,[]},
          {rabbit@controller2,[]},
          {rabbit@controller1,[]}]}]

[iyunv@controller2 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@controller2 ...
[{nodes,[{disc,[rabbit@controller1]},
         {ram,[rabbit@controller3,rabbit@controller2]}]},
{running_nodes,[rabbit@controller3,rabbit@controller1,rabbit@controller2]},
{cluster_name,<<"rabbit@controller1">>},
{partitions,[]},
{alarms,[{rabbit@controller3,[]},
          {rabbit@controller1,[]},
          {rabbit@controller2,[]}]}]
