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

I had the same problem and doing the steps Richard H Fung provided didn't helped me. I also had to uninstall these packages: erlang erlang-epmd rabbitmq-server

zypper remove erlang erlang-epmd rabbitmq-server
rm -rf /var/lib/rabbitmq/*
zypper install erlang erlang-epmd rabbitmq-server
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

If you have another OS than openSUSE just use your package manager to remove these packages (e.g. apt-get)
