问题描述

[root@myserver ~]# rabbitmqctl status
rabbit@myserver:
  * connected to epmd (port 4369) on myserver
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on myserver
  * suggestion: start the node

Current node details:
 * node name: rabbitmqcli86@myserver
 * effective user's home directory: /root
 * Erlang cookie hash: 7zt8h2v9j8Q34mFQo518hA==

解决方法

• 思路:根据错误信息显示，判断为端口重启时，未完成停止服务

[root@myserver sbin]# ss -tnlp |grep  15672
[root@myserver sbin]# ss -tnlp |grep  5672
[root@myserver sbin]# ss -tnlp |grep  25672
[root@myserver sbin]# ss -tnlp |grep  4369

问题描述

[root@myserver ~]# rabbitmqctl status
rabbit@myserver:
  * connected to epmd (port 4369) on myserver
  * epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic 
  * TCP connection succeeded but Erlang distribution failed 

  * Authentication failed (rejected by the remote node), please check the Erlang cookie
  
Current node details:
 * node name: rabbitmqcli39@myserver
 * effective user's home directory: /root
 * Erlang cookie hash: 7zt8h2v9j8Q34mFQo518hA==

解决方法

• 思路: cookie不一致

[root@myserver sbin]# find / -name '.erlang.cookie'
[root@myserver sbin]# cp /root/.erlang.cookie /usr/local/rabbitmq_server-3.7.8/.erlang.cookie
