I’ve been setting up a Debian 6 server with RabbitMQ installed. RabbitMQ is used with Celery to enable asynchronous tasks in Python Django projects. After installing RabbitMQ in one of my servers, I wanted to rename my server’s hostname. That broke RabbitMQ. RabbitMQ failed to start because its database is tied to the hostname. Removing the old installation of RabbitMQ will fix this problem.
Here are steps to reinstall RabbitMQ. These commands are run as the root user:
Step 1. Stop RabbitMQ:
Step 2. Change
Step 3. Change
Step 4. Uninstall old RabbitMQ:
dpkg -P rabbitmq-server
Step 5. Remove RabbitMQ’s database:
rm -rf /var/lib/rabbitmq
Step 6. Find erlang’s process that is running rabbit:
ps ax | grep rabbit
Step 7. Kill the listed process
Step 8. Reinstall RabbitMQ:
apt-get install rabbitmq-server
For further reading, I referenced several articles to get a handle on reinstalling RabbitMQ.
