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

Remove the old installation of RabbitMQ to fix this problem. Here are steps to reinstall RabbitMQ. These commands are run as the root user:

1. Stop RabbitMQ: rabbitmqctl stop

2. Change /etc/hosts

3. Change /etc/hostname

4. Uninstall old RabbitMQ: dpkg -P rabbitmq-server

5. Remove RabbitMQ’s database: rm -rf /var/lib/rabbitmq

6. Find erlang’s process that is running rabbit: ps ax | grep rabbit

7. Kill the listed process

8. Reinstall RabbitMQ: apt-get install rabbitmq-server

I wrote about these steps on my blog.
