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

Have a look what is in the log of the node that you are trying to start. It will be in /var/log/rabbitmq/ It was selinux in my case, rabbit could not bind to its ports.

Answer 2

Seems like the Mnesia database was corrupted. Had to delete it to get sudo service rabbitmq-server start going again !

$ sudo rm -rf /var/lib/rabbitmq/mnesia/

Also make sure that any stray rabbit processes are killed before clearing out

$ ps auxww | grep rabbit | awk '{print $2}' | sudo xargs kill -9

Answer 3

My brew version of rabbitmq refused to start (after working fine for years without modification by me) too.

$ cat /usr/local/etc/rabbitmq/rabbitmq-env.conf
CONFIG_FILE=/usr/local/etc/rabbitmq/rabbitmq
NODE_IP_ADDRESS=127.0.0.1
NODENAME=rabbit@localhost
RABBITMQ_LOG_BASE=/usr/local/var/log/rabbitmq

I edited out rabbit@ on NODENAME and brew services restart rabbitmq started working again.

Answer 4

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.

Answer 5

I had similar problem but these suggestions didn't work for me(restart too). When I run rabbitmq-server command, I get a response like that:

$/ rabbitmq-server


BOOT FAILED
===========

Error description:
   {error,{cannot_log_to_file,"/var/log/rabbitmq/rabbit@haber01.log",
                              {error,eacces}}}
....

When I checked permissions of /var/log/rabbitmq/rabbit@haber01.log file, I saw that group has not write permisson for that file. So I gave permission to group with that command:

/var/log/rabbigmq/$ chmod g+w *

then problem has gone!

Maybe this answer help someone.

Answer 6

If you use celery, your queues could reach max size and rabbit won't start because of that. Maybe you wouldn't even able to use rabbitmqctl, so if you can afford to clean the queues, just remove

/var/lib/rabbitmq/mnesia/rabbit@<host>/queues

on unix (look for mnesia DB path on your system). Be careful: this will remove everything you have in rabbit, so this is a last solution ever.
