Windows下RabbitMQ报错:Error: unable to perform an operation on node

问题

运行rabbitmqctl 相关命令(如rabbitmqctl  stop)报错:

Stopping and halting node rabbit@DESKTOP-8VB0JLG ...
Error: unable to perform an operation on node 'rabbit@DESKTOP-8VB0JLG'. 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 http://rabbitmq.com/documentation.html to learn more
 * Consult server logs on node rabbit@DESKTOP-8VB0JLG

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

attempted to contact: ['rabbit@DESKTOP-8VB0JLG']

rabbit@DESKTOP-8VB0JLG:
  * connected to epmd (port 4369) on DESKTOP-8VB0JLG
  * 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: 'rabbitmqcli77@DESKTOP-8VB0JLG'
 * effective user's home directory: C:\Users\rock
 * Erlang cookie hash: 0rVZh7WgaAP8H8hmZPiGLA==

解决方案

  1. 将C:\Users\{用户名}\.erlang.cookie 复制到 C:\Windows\System32\config\systemprofile 目录。
  2. 重启rabbitMQ服务
