C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.4\sbin>rabbitmqctl status
Status of node rabbit@DESKTOP-7IAJK37 ...                                                                               Error: unable to perform an operation on node 'rabbit@DESKTOP-7IAJK37'. 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-7IAJK37

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

attempted to contact: ['rabbit@DESKTOP-7IAJK37']

rabbit@DESKTOP-7IAJK37:
  * connected to epmd (port 4369) on DESKTOP-7IAJK37
  * 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: 'rabbitmqcli38@DESKTOP-7IAJK37'
* effective user's home directory: C:\Users\itsvse_pc
* Erlang cookie hash: RmzKErjVZUcsMU8wSgBGbA==

rabbitMQ使用的cookie为：C:\Users\itsvse_pc\.erlang.cookie  这里面的应该和上面cookie部分相同
问题原因：

我本机管理员名称为itsvse_pc，我是用itsvse_pc账号登录服务器并安装rabbitmq的，rabbitmq也自动在C：\user\itsvse_pc下创建了一个.erlang.cookie文件，但是RabbitMQ服务启动的时候，执行者是local system account，如下图所示：



解决办法：

使用本机安装的账户来启动服务，拿本机为例，也就是用itsvse_pc账户来启动服务，如下图：



设置完成后，点击应用和保存，然后重启服务！！！！！重启服务！！

再次执行rabbitmqctl status，成功！

查看所有队列信息   rabbitmqctl list_queues
查看服务状态信息   rabbitmqctl -q status
