Node failed to boot with ERROR: distribution port 25672 in use by another node

[hongbosen]

I'm trying to start my rabbitmq server using command:systemctl start rabbitmq-server on centos 7.5 docker but it crashes.
I have absolutely no clue whatsoever as to what I should do.
Rabbitmq version: 3.8.9 erlang version: 23

[root@prod /]# rabbitmq-server status

Any help would be great。

ERROR: distribution port 25672 in use by another node: rabbit@prod

is quite specific: another node, named rabbit@prod, uses port 25672. With some very specific exceptions, and certainly in the case of RabbitMQ, two processes cannot use the same port: the OS will not allow for that.

You have to stop that node before this one can start e.g. using

rabbitmqctl shutdown -n rabbit@prod

If you are looking to run several cluster nodes on a single host, see this Clustering guide section. This is definitely not something that we'd recommend in "prod" (production) systems.
