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

by

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.
