rabbitmq-server fails to start after hostname has changed for first time

Question

I am using django-celery for my django project. Last day I have changed my computer\'s hostname (I am using Ubuntu 12.04, edited file \'/etc/hostname\'), and after next restart

Answer 1

To solve this problem, I changed my /etc/hostname file with the new hostname then restarted the machine. After that, I ran rm -rf /var/lib/rabbitmq/mnesia/*

Then restarted the service : sudo service rabbitmq-server restart

At this point, it worked for me. If it still don't work, modify the file /etc/rabbitmq/rabbitmq-env.conf by adding those informations :

NODENAME=rabbit@YOUR_NEW_HOSTNAME
NODE_IP_ADDRESS=127.0.0.1
NODE_PORT=5672

Then restart the service : sudo service rabbitmq-server restart

Hope it helps.
