2017 - brew options changed and its much simpler now:

$ brew info rabbitmq
<snip>

To have launchd start rabbitmq now and restart at login:
  brew services start rabbitmq
Or, if you don't want/need a background service you can just run:
  rabbitmq-server

@Aarpy
thanks for this. I was on the same boat scratching my head where the plist are found

@Aarpy that is very useful thanks. But it does not behave the same as I usually do with sudo (sudo rabbitmq-server). Any idea why?

sudo brew services start rabbitmq doesn't work either.
And performing ps aux | grep rabbit doesn't show any processes when using the brew commands, only when I do sudo rabbitmq-server.

Tracking issue Homebrew/homebrew-core#17446
