    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.

    REVISION

    I moved my blog to a new website.
