[Bug 1585043] Re: rabbitmq-server fails to start when /var/log/rabbitmq does not exist

[Joshua Powers]

Well that was fast as I had a quick back and forth on that bug I linked
above. Feel free to add any more details if you want.

The heart of the issue comes down to the fact that the rabbitmq-server
runs as a non-root user who will not have permissions to create a
directory in /var/log. The result is not being able to create the log
directory and failure to start. To be fair, rabbitmq-server does try to
create the directory as noted in the Github issue above.

One solution to avoid this, the rabbitmq-server packaging would need to
be changed to run the service as a root user or log to somewhere it
would have permissions to going forward. I do not believe we would want
to change this, so I am going to mark this bug as "wont fix". If you
have any further details, questions, or notes feel free to add them here
or to the Github bug above.

Title:
  rabbitmq-server fails to start when /var/log/rabbitmq does not exist

Status in RabbitMQ:
  Unknown
Status in rabbitmq-server package in Ubuntu:
  Won't Fix

Bug description:
  rabbitmq-server fails to start (`sudo service [re]start rabbitmq-
  server`) if the log directory (`/var/log/rabbitmq` by default) does
  not exist.

  It's a frequent use-case for people who mount `/var/log` as `tmpfs`
  (e.g. for SSD optimization).

  The script just hangs forever and does not provide any useful output
  nor (you guessed it) any log.

  Running `sudo mkdir /var/log/rabbitmq && sudo chown rabbitmq:rabbitmq
  /var/log && sudo service rabbitmq-server restart` starts it
  successfully, though.

  Bug noticed on rabbitmq-server 3.6.2-1 but it may affect other
  versions too.

  Feel free to ask more information, I reproduce this bug every single
  morning when starting my computer ;-)
