本文详细记录了在尝试启动RabbitMQ服务器时遇到的错误：节点名称冲突及停止RabbitMQ时连接失败的问题。通过诊断信息，发现可能是由于主机名不匹配或cookie设置不正确导致的。解决方案为终止相关进程并重新启动。

执行 ./rabbitmq-server start 报错

[root@iZ2ze3269bclc6z4m26wrlZ sbin]# ./rabbitmq-server start
ERROR: node with name "rabbit" already running on "iZ2ze3269bclc6z4m26wrlZ"

执行./rabbitmqctl stop 报错

[root@iZ2ze3269bclc6z4m26wrlZ sbin]# ./rabbitmqctl stop
Stopping and halting node rabbit@iZ2ze3269bclc6z4m26wrlZ ...
Error: unable to connect to node rabbit@iZ2ze3269bclc6z4m26wrlZ: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@iZ2ze3269bclc6z4m26wrlZ]

rabbit@iZ2ze3269bclc6z4m26wrlZ:
  * connected to epmd (port 4369) on iZ2ze3269bclc6z4m26wrlZ
  * epmd reports node 'rabbit' running on port 25672
  * TCP connection succeeded but Erlang distribution failed
  * suggestion: hostname mismatch?
  * suggestion: is the cookie set correctly?

current node details:
- node name: 'rabbitmqctl-27021@iZ2ze3269bclc6z4m26wrlZ'
- home dir: /root
- cookie hash: ADDM6B7MKBxUsNxaFIVqLw==

这种问题杀死线程重启就行了
