Error: unable to perform an operation on node 'rabbit@emily2'. Please see diagnostics information and suggestions below.
Most common reasons for this are:
* Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
* CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
* Target node is not running
In addition to the diagnostics info below:
* See the CLI, clustering and networking guides on https://rabbitmq.com/documentation.html to learn more
* Consult server logs on node rabbit@emis2
* If target node is configured to use long node names, don't forget to use --longnames with CLI tools
DIAGNOSTICS

* epmd reports: node 'rabbit' not running at all
no other nodes on emis2
* suggestion: start the node

RabbitMQ报以上错误时是由于当前节点mnesia数据库中记录还在集群之中，但是集群确认为其已经不咋集群中了，解决方案是：
- 删除当前节点/var/lib/rabbit/mnesia数据库记录
- 确保/var/lib/rabbit/.erlang.cookie中的key和集群中的保持一致
- rabbitmq-server start -detached启动erlang和rabbitmq服务器
- rabbitmqctl stop_app停止rabbitmq服务器
- rabbitmqctl join_cluster rabbit@emily2 加入集群
- rabbitmqctl start_app启动当前节点rabbitmq
