RabbitMQ:Erlang distribution failed解决方案

前言

        系统版本:CentOS Linux release 7.7.1908 (Core)

        通过rabbitmqctl add_user admin 12345指令,给rabbitmq添加用户提示出错:

[[email protected] perl]# rabbitmqctl add_user admin 12345
Error: unable to connect to node [email protected]: nodedown

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

attempted to contact: [[email protected]]

[email protected]:
  * connected to epmd (port 4369) on localhost
  * epmd reports node 'rabbit' running on port 25672
  * TCP connection succeeded but Erlang distribution failed

  * Authentication failed (rejected by the remote node), please check the Erlang cookie


current node details:
- node name: '[email protected]'
- home dir: /root
- cookie hash: BgvEr+lGkDjLTQzT85cpyw==


解决方案

1)搜索.erlang.cookie文件

[[email protected] mnesia]# find / -name *.cookie
/root/.erlang.cookie
/opt/rabbitmq_server-3.6.10/.erlang.cookie

2)覆盖掉/root/.erlang.cookie文件

cp /opt/rabbitmq_server-3.6.10/.erlang.cookie  /root/


原因

RabbitMQ的.erlang.cookie和用户的cookie冲突了,需要用RabbitMQ的cookie去覆盖用户的cookie
