RabbitMQ Cluster Status

[Ashutosh R]

Hi,

I am trying to setup cluster for RabbitMQ. RabbitMQ is up and running. I can use management plugin to browse Management portal. But when I try to run

rabbitmqctl cluster_status

I got the following error. How can I fix this?

Cluster status of node 'rabbit@hostname' ...

Error: unable to connect to node 'rabbit@hostname': nodedown

DIAGNOSTICS

===========

attempted to contact: ['rabbit@hostname']

rabbit@hostname:

  * connected to epmd (port 4369) on hostname

  * epmd reports node 'rabbit' running on port 25672

  * TCP connection succeeded but Erlang distribution failed

  * suggestion: hostname mismatch?

  * suggestion: is the cookie set correctly?

  * suggestion: is the Erlang distribution using TLS?

current node details:

- node name: nonode@nohost

- home dir: /home/username

- cookie hash: 92vmrYD/iLl+OKWxh4sJhQ==

Thanks

The above lines provide a clue and some suggestions.

`rabbitmqctl` cannot authenticate to the node. See the section on the Erlang
cookie on http://www.rabbitmq.com/clustering.html. This is one of the most
frequently asked questions on this list, too.

Hi Michael,

I have cookies in two places. One in /var/lib/rabbitmq/.erlang.cookie and other in /home/username/.erlang.cookie.

I have already made both cookie value same. 

When I try to get the status of rabbitmq using the following command, it gives me that error

sudo ./rabbitmqctl status

But the following command works

sudo /sbin/service rabbitmq-server status

Is it something incorrect?

you use sudo, therefore $HOME is quite possibly  neither /var/lib/rabbitmq ($HOME of user rabbitmq)
nor /home/username ($HOME of username).

[Ashutosh R]

I did not get that part. Do I need to set $HOME? I do not have root access so have to use sudo.

Hi Ashutosh ,

Did you manage to get  a resolution of this issue ?

Can you please share it ?

[Michael Klishin]

There are clues and a doc link right in this thread.

Please put in some effort of your own.
