rabbitmq pod正常运行，查看pod日志也没有发现异常报错。
我们进入容器查看插件是否正常启用：
$ kubectl exec -it rabbitmq-hitch-0 -n rabbitmq -- rabbitmq-plugins list
Listing plugins with pattern ".*" ...
Configured: E = explicitly enabled; e = implicitly enabled

可以看到rabbitmq_management 插件未启用，这是导致 RabbitMQ 后台管理界面无法访问的主要原因。rabbitmq_management 是 RabbitMQ 的管理插件，负责提供 HTTP API 和 Web 管理界面。
执行如下命令启动插件：
$ kubectl exec -it rabbitmq-hitch-0 -n rabbitmq -- rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@rabbitmq-hitch-0.rabbitmq-hitch-headless.rabbitmq.svc.cluster.local:
rabbitmq_management
The following plugins have been configured:
rabbitmq_delayed_message_exchange
rabbitmq_management
rabbitmq_management_agent
rabbitmq_web_dispatch
Applying plugin configuration to rabbit@rabbitmq-hitch-0.rabbitmq-hitch-headless.rabbitmq.svc.cluster.local...
The following plugins have been enabled:
rabbitmq_management
rabbitmq_management_agent
rabbitmq_web_dispatch
started 3 plugins.
再次查看是否启动：
$ kubectl exec -it rabbitmq-hitch-0 -n rabbitmq -- rabbitmq-plugins list
Listing plugins with pattern ".*" ...
