rabbitmq refusing to start

Question

I have installed rabbitmq on ubuntu and trying to start it using rabbitmq-server start, however, I\'m getting this error:

Activating Ra         


        

Answer 1

rabbitmq-server refuses to start if the hostname -s value has changed.

The solution suggested here is only for test/development environments.

I had to delete the database to fix it locally. i.e empty folder /var/lib/rabbitmq (ubuntu) or /usr/local/var/lib/rabbitmq/(mac)
