Posted 2020-11-03 秋华

C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.4\sbin>rabbitmqctl list_queues

Error: unable to perform an operation on node ‘[email protected]‘.

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 [email protected]

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

attempted to contact: [[email protected]]

[email protected]:  

* connected to epmd (port 4369) on B62B562G5YL36KA  

* 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: [email protected]  

* effective user‘s home directory: C:\Users\Administrator  

* Erlang cookie hash: D+xLmf+NlPkE9AReiKUnRw==

解决方法，如果服务启动了将C:\Windows\system32\config\systemprofile\.erlang.cookie中的.erlang.cookie拷贝到你的effective user‘s home directoryC:\Users\Administrator  下面。
