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

Thanks to Richard H Fung.

His steps helped me to solve this issue.

But I did not have to re-install the rabbitmq.

When I opened my /etc/hosts file I found that IP assigned to my hostname is different than the actual ip(192.168.1.200 [static]).

#/etc/hosts  
127.0.0.1       localhost  
192.168.1.115   HOSTNAME

so I just changed IP address to 192.168.1.200 in my /etc/hosts file and it worked fine.
