RabbitMQ, Erlang: How to “make sure the erlang cookies are the same”

Question

I am using RabbitMQ with Grails, and a problem cropped up this morning. When I run rabbitmqctl status it tells me:

C:\\Users\\BuildnTest2>rab         


        

Answer 1

Make sure the rabbitmq erlang.cookie matches the erlang.cookie in your user directory:

The rabbitmq erlang cookie...

...will be typically located in /var/lib/rabbitmq/.erlang.cookie on Unix systems and C:\Users\Current User.erlang.cookie or C:\Documents and Settings\Current User.erlang.cookie on Windows systems. (http://www.rabbitmq.com/clustering.html#setup)

Make sure that matches with ~/.erlang.cookie.
