​1.安装​

#1.
yum install rabbitmq-server -y

#2.
装完以后，暂时不启动
做高可用，要解析出每个主机的主机名，修改hosts文件进行解析
[root@mariadb ~]# cat /etc/hosts
192.168.47.28 mariadb
192.168.47.29 mariadb2

#3.
#端口5672 客户端使用；集群通讯使用端口：25672
[root@mariadb ~]# systemctl start rabbitmq-server

#4.打开rabbitMQ的web插件：可从浏览器查看当前主机的状态 端口15672  
[root@mariadb ~]# rabbitmq-plugins enable rabbitmq_management 
--------------------------------------------------------
The following plugins have been enabled:
  mochiweb
  webmachine
  rabbitmq_web_dispatch
  amqp_client
  rabbitmq_management_agent
  rabbitmq_management
Plugin configuration has changed. Restart RabbitMQ for changes to take effect.

#5.打开插件后必须重新启动一次
[root@mariadb ~]# systemctl restart rabbitmq-server
[root@mariadb ~]# systemctl status   rabbitmq-server
[root@mariadb ~]# systemctl enable   rabbitmq-server

#6.
[root@mariadb ~]# rabbitmq-plugins list #查看插件

#7.访问
192.168.47.28:15672  #账户/密码：默认guest

​2.​高可用​​

#1.查看集群状态
[root@mariadb ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@mariadb ...
[{nodes,[{disc,[rabbit@mariadb]}]},
 {running_nodes,[rabbit@mariadb]},
 {cluster_name,<<"rabbit@mariadb">>},
 {partitions,[]}]
...done.
#2.加入集群条件
2.1.cookie是否一致
scp /var/lib/rabbitmq/.erlang.cookie 192.168.47.29:/var/lib/rabbitmq/.erlang.cookie 
systemctl restart rabbitmq-server 
[root@mariadb ~]# cat  /var/lib/rabbitmq/.erlang.cookie
UAUYPUZHUTXUVTAFLGZN
[root@mariadb2 ~]# cat  /var/lib/rabbitmq/.erlang.cookie
UAUYPUZHUTXUVTAFLGZN
2.2.能不能解析对方的主机名,修改/etc/hosts文件
vim /etc/hosts
------------------------
192.168.1.148 mariadb1
192.168.1.149 mariadb2

#3.加入到集群中
要把哪个节点加入到集群，先要把该节点清空，先停止
[root@mariadb2 ~]# rabbitmqctl  stop_app   #停止应用程序
[root@mariadb2 ~]# rabbitmqctl  reset      #清空数据
#将mariadb2添加到集群当中，并成为内存节点，不加--ram默认是磁盘节点 ；执行要成功，需要满足[加入集群条件]
[root@mariadb2 ~]# rabbitmqctl  join_cluster rabbit@mariadb --ram
--------------------------------------------------------------
Clustering node rabbit@mariadb2 with rabbit@mariadb ...
...done.
[root@mariadb2 ~]# rabbitmqctl start_app
--------------------------------------------------------------
Starting node rabbit@mariadb2 ...
...done.
[root@mariadb2 ~]# rabbitmqctl cluster_status
--------------------------------------------------------------
Cluster status of node rabbit@mariadb2 ...
[{nodes,[{disc,[rabbit@mariadb]},{ram,[rabbit@mariadb2]}]},
 {running_nodes,[rabbit@mariadb,rabbit@mariadb2]},
 {cluster_name,<<"rabbit@mariadb">>},
 {partitions,[]}]
...done.
#4.改成镜像模式
[root@mariadb2 ~]# rabbitmqctl set_policy  ha-all "#"  '{"ha-mode":"all"}'
------------------------------------------------------------------------------------------
Setting policy "ha-all" for pattern "#" to "{\"ha-mode\":\"all\"}" with priority "0" ...
...done.  
"#"为任意0个或多个即为所有，也可以使用"^test"匹配开头，还可以使用其他正则匹配

#5.创建用户及配置权限
[root@mariadb2 ~]# rabbitmqctl add_user openstack openstack123            #任何一个节点创建
Creating user "openstack" ...
...done.
[root@mariadb2 ~]# rabbitmqctl set_permissions  openstack ".*" ".*" ".*"  #配置权限
Setting permissions for user "openstack" in vhost "/" ...
...done.
