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 is set to start automatically after it's installed. I don't think it is configured run with the service command.

To see the status of rabbitmq

sudo rabbitmqctl status

To stop the rabbitmq

sudo rabbitmqctl stop

(Try the status command again to see that it's stopped). To start it again, the recommended method is

sudo invoke-rc.d rabbitmq-server start

These all work with the vanilla ubuntu install using apt-get

Still not working?

If you've tried unsuccessfully to start or restart rabbitmq, check to see how many processes are running.

ps -ef | grep rabbit

There should be 5 processes running as the user rabbitmq. If you have more, particularly if they're running as other users (such as root, or your own user) you should stop these processes.

The cleanest way is probably to reboot your machine.
