在RedHat 7.6上安装新的RabbitMQ之后，我遇到了一些问题 RabbitMQ版本是3.7.7.6。 Erlang版本是21.2.5-这两个兼容。
安装后，我启动RabbitMQ服务器。没问题。
一旦我要添加用户或配置任何内容，它将失败。例如：
[root@blabla ~]# rabbitmqctl status
(.....)
Only webadmin or rabbitmq can run rabbitmqctl
我尝试了一个，但现在我遇到了有关Erlang cookie的新问题：
[root@blabla ~]# sudo -u webadmin rabbitmqctl status
Status of node rabbit@blabla ...
Error: unable to perform an operation on node 'rabbit@blabla'. 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@blabla
DIAGNOSTICS
===========
attempted to contact: ['rabbit@blabla']
rabbit@blabla:
* connected to epmd (port 4369) on blabla
* 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
我已经检查过Can't access rabbitmq mgmt，但所有答案都必须能够使用Rabbitmq-plugins或Rabbitmqtl，而我不能。
服务器已启动并且正在工作（systemctl启动rabbitmq），我可以在端口15672上远程访问它。显然，我无法使用来宾/来宾进行连接，但这是目前的预期行为。同样，这里没有群集设置，只是“简单”安装。
