RabbitMQ 错误解决

1. 安装好mq后，查看状态，错误

S D:\RabbitMQ Server\rabbitmq_server-3.7.0\sbin> .\rabbitmqctl status  
Status of node rabbit@DESKTOP-ECFDCQB ...  
Error: unable to perform an operation on node 'rabbit@DESKTOP-ECFDCQB'. 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-ECFDCQB

  * epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic  
  * TCP connection succeeded but Erlang distribution failed

解决方法：

将C:\Users\ *** \ .erlang.cookie 文件

拷贝到C:\Windows\System32\config\systemprofile替换掉.erlang.cookie文件
