RabbitMQ on Ubuntu 10.04 Server

Question

Trying to run RabbitMQ on VPS with Ubuntu 10.04. Doing everything like usual:

• added RabbitMQ deb repo
• updated with apt-get update
• installed with apt-get install rabbitmq-server

On my local machine with Ubuntu 11.10 and another VPS with same 10.04 everything works just fine. But on this one i getting error like this (from /var/log/rabbitmq/startup_log):

    Activating RabbitMQ plugins ...

********************************************************************************
********************************************************************************

0 plugins activated:

ERROR: epmd error for host "67714": badarg (unknown POSIX error)

What i'm doing wrong and wtf is this?

Answer 1

This worked for me on CentOS 5.8 when I was unable to use the /etc/hosts file to fix it:

1. Create a rabbitmq environment variables config file at /etc/rabbitmq/rabbitmq-env.conf
2. Add NODENAME=rabbit@localhost to it (note that just localhost didn't work)
3. sudo service rabbitmq-server start
