该文详细描述了如何使用Docker创建RabbitMQ集群，包括设置容器连接，通过命令行进行集群配置，如停止应用、重置、加入集群，以及检查集群状态。同时，文中还介绍了如何添加和设置具有管理员权限的用户。

一、创建容器并建立连接

主myrabbit1:

docker run -d --hostname rabbit1 --name myrabbit1 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' -p 15672:15672 -p 5672:5672 rabbitmq:3.11-management

从myrabbit2要连接myrabbit1：

docker run -d --hostname rabbit2 --name myrabbit2 -p 15673:15672 -p 5673:5672 --link myrabbit1:rabbit1 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' rabbitmq:3.11-management

从mytabbit3要连接myrabbit1和myrabbit2：

docker run -d --hostname rabbit3 --name myrabbit3 -p 15674:15672 -p 5674:5672 --link myrabbit1:rabbit1 --link myrabbit2:rabbit2 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' rabbitmq:3.11-management

查看是否部署成功：

二、进入容器配置集群

先进入容器1，将容器重置：

docker exec -it myrabbit1 bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
exit

同样的方式再去配置2和3，但是2和3要加入1的集群，以1为主节点，23为从节点:

docker exec -it myrabbit2 bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rabbit1
rabbitmqctl start_app
exit

参数“–ram”表示设置为内存节点，忽略此参数默认为磁盘节点。

docker exec -it myrabbit3 bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rabbit1
rabbitmqctl start_app
exit

都配置好了以后可以再去rabbit1中看一下是否形成集群：

docker exec -it myrabbit1 bash
rabbitmqctl cluster_status
exit

可以看到结果是：

xzd@xzd-virtual-machine:~$ docker exec -it myrabbit1 bash
root@rabbit1:/# rabbitmqctl cluster_status
Cluster status of node rabbit@rabbit1 ...

说明已经完成了集群部署！

我们也可以进入到RabbitMQ可视化界面查看一下：

找到IP地址：http://192.168.235.132:15672/#/

用户名：guest 密码：guest

进入可以查看已经形成了集群

三、【额外】设置一下管理员账号

设置管理员账号目的是设置一个可以获取全部权限。

如果是完成第二步后，下面任意一个机子部署就好了，所有都能设置上去。

docker exec -it myrabbit1 bash
rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
exit

docker exec -it myrabbit2 bash
rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
exit

docker exec -it myrabbit3 bash
rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
exit
