rabbitMQ，MQ全稱為Message Queue，訊息列隊是一種應用程式對應#用程式的通訊方法。應用程式通過讀寫出入的訊息（針對應喲程式的資料）來通訊，而無需專用連線來連結它們。

在centos7上構建rabbitmq單節點叢集

centos7+網路環境

安裝rabbitmq-server：

新增任意一個openstack的映象源（yum -y install centos-release-openstack-pike.x86_64）
[root@centos7 ~]# yum -y install rabbitmq-server

啟動：

[root@centos7 ~]# systemctl start rabbitmq-server
[root@centos7 ~]# systemctl status rabbitmq-server
● rabbitmq-server.service - RabbitMQ broker
Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; disabled; vendor preset: disabled)
Active: active (running) since Sat 2019-05-11 08:07:50 EDT; 1s ago
 Main PID: 10915 (beam)
Status: "Initialized"
CGroup: /system.slice/rabbitmq-server.service
├─10915 /usr/lib64/erlang/erts-7.3.1.2/bin/beam -W w -A 64 -P 1048576 -t 5000000 -stbt db -K true ...
├─11096 inet_gethost 4
└─11097 inet_gethost 4

配置管理員使用者：

[root@centos7 ~]# rabbitmqctl add_user admin admin
Creating user "admin" ...
[root@centos7 ~]# rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
[root@centos7 ~]# rabbitmqctl set_permissions admin ".*" ".*" ".*"
Setting permissions for user "admin" in vhost "/" ...

新增rabbit-2節點：

[root@centos7 ~]# RABBITMQ_NODE_PORT=5673 RABBITMQ_NODENAME=rabbit-2 rabbitmq-server -detached（rabbitm預設埠號為5672）
Warning: PID file not written; -detached was passed.（警告好像沒什麼用）
[root@centos7 ~]# rabbitmqctl -n rabbit-2 stop_app
Stopping node 'rabbit-2@centos7' ...
[root@centos7 ~]# rabbitmqctl -n rabbit-2 join_cluster rabbit@`hostname -s`
Clustering node 'rabbit-2@centos7' with rabbit@centos7 ...
[root@centos7 ~]# rabbitmqctl -n rabbit-2 start_app
Starting node 'rabbit-2@centos7' ...

查詢叢集狀態：

[root@centos7 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@centos7 ...
[{nodes,[{disc,['rabbit-2@centos7',rabbit@centos7]}]},
 {running_nodes,['rabbit-2@centos7',rabbit@centos7]},
 {cluster_name,<<"rabbit@centos7">>},
 {partitions,[]},
 {alarms,[{'rabbit-2@centos7',[]},{rabbit@centos7,[]}]}]

附：

啟動rabbitmqWeb介面：

[root@centos7 ~]# rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management

Applying plugin configuration to rabbit@centos7... started 6 plugins.
預設埠號為15672
