访问
http://192.168.99.100:15672，弹出登陆界面。输入guest/guest
然后就可以添加用户了。
Docker搭建RabbitMQ集群（多机版）
上面我们使用Docker搭建出了一个RabbitMQ单机集群，这种模式只能用来测试玩玩，无法再生产环境中使用。在生产环境中，需要把3个节点的集群分布到各个主机上面去。这个时候docker-compose就需要做调整了，主要是对外端口和link方式，首先我们说一下RabbitMQ开启后的对外端口。
SELinux和类似机制或许会通过绑定端口的方式阻止RabbitMQ。当这种情况发生时，RabbitMQ会启动失败。请确认以下的端口是可以被打开的：
4369 (epmd)
25672 (Erlang distribution)
5672, 5671 (启用了或者未启用TLS的AMQP 0-9-1)
15672 (如果管理插件被启用)
61613, 61614 (如果STOMP被启用)
1883, 8883 (如果MQTT被启用)
说完端口，下面提供一个三节点的docker-compose文件。

然后依序在三个节点上分别开启rabbitmq，然后随意找个节点打开IP:25672，输入guest用户名和guest密码就可以查看集群了。
