osx - RabbitMmq on Mac can't start -

I have established a rabbit on Mac OS X through homebrew, just a simple command:

$ Brew Rabbitmq Install

But, when I start the server via rabbitmq-server, then it happens:

Error: Distribution port in use on localhost 25672 (Through non-Arling process)

I have to get some process that uses port 25672, but I do not really feel strange

Anyone know the reason for this, too much thx :)

to use sudo Lsof -i: 25672 pseudo can be required depending on user permissions or not.
