RabbitMQ failed to start, TCP connection succeeded but Erlang distribution failed


I'm a new one just start to learn and install RabbitMQ on Windows System.

I install Erlang VM and RabbitMQ in custom folder, not default folder (Both of them).

Then I have restarted my computer.

By the way,My Computer name is "NULL"


I cd to the RabbitMQ/sbin folder and use command:

rabbitmqctl status

But the return message is:

Status of node rabbit@NULL ...

Error: unable to perform an operation on node 'rabbit@NULL'. 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:

DIAGNOSTICS

attempted to contact: [rabbit@NULL]

rabbit@NULL:

  • connected to epmd (port 4369) on NULL
  • 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: rabbitmqcli70@NULL
  • effective user's home directory: C:\Users\Jerry Song
  • Erlang cookie hash: 51gvGHZpn0gIK86cfiS7vp==

I have try to RESTART RabbitMQ, What I get is:

ERROR: node with name "rabbit" already running on "NULL"


By the way,My Computer name is "NULL" And I have enable all ports in firewall.


Solution

  • I have reinstalled the RabbitMQ in my computer by using default setup folder

    Then checked with the command :

    rabbitmqctl status

    It works now, not the problem of Erlang VM .(Means Er can install at another folder)

    It will cause some problem (like this one) that I couldn't find out now if we don't use the RabbitMQ default setup require folder (C:\Program Files\RabbitMQ Server)

    If anyone finds it out, I hope you can tell me why and how to fix.
