RabbitMQ is dead - rabbitmq

Question

I don't actually know how to describe my problem in my title well. The issue I'm having is I have a local install of RabbitMQ through Homebrew (Mac), and it suddenly just died. I suddenly became unable to send messages to the queue. Unfortunately I can't post the error message, because I tried a few other steps, including resetting, uninstalling, and reinstalling Rabbit. After the reinstall, I can't start my Rabbit server; it gets stuck after this:
sudo rabbitmq-server start

After this it just hangs forever.
I would like to completely uninstall Rabbit from my computer and reinstall it from fresh; when I first installed it it worked like a charm, but since them somehow something has gone belly-up. Can someone help me with this?
Also, yes, the obvious thing to do is brew rm rabbitmq but that's what got me into this situation. It can't be that simple.

Answer 1

I got it working. Some combination of these steps worked:
Change the permission of the service:
sudo chown -R $(whoami) $(brew --prefix)/*
Reload the launchctl config:
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist
Restart the service:
brew services restart rabbitmq
And then it worked.
