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' * effective user's home directory: C:\Users\rock

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
