How to start RabbitMQ cluster with IP addresses and no DNS entry?

Question

I am trying to create a RabbitMQ cluster using nodes that have no entries in DNS. Even though I have added the respective entries in /etc/hosts, the cluster always fails with this error: ``` $ rabbitmqctl join_cluster rabbit@pcomdvsns1 Clustering node rabbit@pcomdvsns2 with rabbit@pcomdvsns1 ... Error: {cannot_discover_cluster,"The nodes provided are either offline or not running"} ``` Is DNS entry a must for getting this started?

Accepted Answer

Make sure that in your `/etc/hosts` there is an entry for `pcomdvsns1` pointing to the correct IP, then verify if you can reach your node using:

```
rabbitmqctl status -n rabbit@pcomdvsns1
```

Then check if you have the same erlang cookies on both servers.
