参考文档:https://blog.csdn.net/belonghuang157405/article/details/83540148
一、拉取rabbitmq镜像
在centos窗口中,执行如下命令:

docker pull rabbitmq:3.7-management

二、创建映射数据卷目录,启动rabbitmq容器
在centos窗口中,执行如下命令创建文件夹:

mkdir rabbitmqcluster
cd rabbitmqcluster/
mkdir rabbitmq01 rabbitmq02 rabbitmq03

操作日志如下:

[root@localhost rabbitmqcluster]# pwd
/home/soft/
[root@localhost soft]# mkdir rabbitmqcluster
[root@localhost soft]# cd rabbitmqcluster/
[root@localhost rabbitmqcluster]# mkdir rabbitmq01 rabbitmq02 rabbitmq03

注:请读者自行找寻创建数据映射目录。
创建完成映射目录后,在centos窗口中,执行如下命令创建容器:

docker run -d --hostname rabbitmq01 --name rabbitmqCluster01 -v /home/soft/rabbitmqcluster/rabbitmq01:/var/lib/rabbitmq -p 15672:15672 -p 5672:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie' rabbitmq:3.7-management

docker run -d --hostname rabbitmq02 --name rabbitmqCluster02 -v /home/soft/rabbitmqcluster/rabbitmq02:/var/lib/rabbitmq -p 15673:15672 -p 5673:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie'  --link rabbitmqCluster01:rabbitmq01 rabbitmq:3.7-management

docker run -d --hostname rabbitmq03 --name rabbitmqCluster03 -v /home/soft/rabbitmqcluster/rabbitmq03:/var/lib/rabbitmq -p 15674:15672 -p 5674:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie'  --link rabbitmqCluster01:rabbitmq01 --link rabbitmqCluster02:rabbitmq02  rabbitmq:3.7-management

注: –hostname 设置容器的主机名
RABBITMQ_ERLANG_COOKIE 节点认证作用,部署集成时 需要同步该值

启动容器成功后,读者可以访问

查看是否正常启动成功。账号/密码:guest / guest。
读者登陆后,查看overview Tab页,可看到节点信息。

三、容器节点加入集群
首先在centos窗口中,执行如下命令,进入第一个rabbitmq节点容器:

docker exec -it rabbitmqCluster01 bash

进入容器后,操作rabbitmq,执行如下命令:

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
exit

操作日志信息如下:

[root@localhost rabbitmq01]# docker exec -it rabbitmqCluster01 bash
root@rabbitmq01:/# rabbitmqctl stop_app
Stopping rabbit application on node rabbit@rabbitmq01 ...
root@rabbitmq01:/# rabbitmqctl reset
Resetting node rabbit@rabbitmq01 ...
root@rabbitmq01:/# rabbitmqctl start_app
Starting node rabbit@rabbitmq01 ...
 completed with 3 plugins.
root@rabbitmq01:/# exit
exit

接下来,进入第二个rabbitmq节点容器,执行如下命令:

docker exec -it rabbitmqCluster02 bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rabbitmq01
rabbitmqctl start_app
exit

操作日志信息如下:

[root@localhost rabbitmq01]# docker exec -it rabbitmqCluster02 bash
root@rabbitmq02:/# rabbitmqctl stop_app
Stopping rabbit application on node rabbit@rabbitmq02 ...
root@rabbitmq02:/# rabbitmqctl reset
Resetting node rabbit@rabbitmq02 ...
root@rabbitmq02:/# rabbitmqctl join_cluster --ram rabbit@rabbitmq01
Clustering node rabbit@rabbitmq02 with rabbit@rabbitmq01
root@rabbitmq02:/# rabbitmqctl start_app
Starting node rabbit@rabbitmq02 ...
 completed with 3 plugins.
root@rabbitmq02:/# exit
exit

最后,进入第三个rabbitmq节点容器,执行如下命令:

docker exec -it rabbitmqCluster03 bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rabbitmq01
rabbitmqctl start_app
exit

操作日志信息如下:

[root@localhost rabbitmq01]# docker exec -it rabbitmqCluster03 bash
root@rabbitmq03:/#  rabbitmqctl stop_app
Stopping rabbit application on node rabbit@rabbitmq03 ...
root@rabbitmq03:/# rabbitmqctl reset
Resetting node rabbit@rabbitmq03 ...
root@rabbitmq03:/# rabbitmqctl join_cluster --ram rabbit@rabbitmq01
Clustering node rabbit@rabbitmq03 with rabbit@rabbitmq01
root@rabbitmq03:/# rabbitmqctl start_app
Starting node rabbit@rabbitmq03 ...
 completed with 3 plugins.
root@rabbitmq03:/# exit
exit

执行上述操作,这时候 再查看 http://192.168.9.219:15672/#/ 的overview面板中的Nodes信息,可查看到节点信息。
