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

When on Windows (sorry about that - I understand the topic is for Ubuntu) just reinstall the RabbitMQ service:

rabbitmq-service.bat remove
rabbitmq-service.bat install

The script is located at C:\Program Files\RabbitMQ Server\rabbitmq_server-\sbin folder.

Or may be just changing the value of HKEY_LOCAL_MACHINE\SOFTWARE\Ericsson\Erlang\ErlSrv\1.1\RabbitMQ\@SName is enough.
