I'm using rabbit 3.0.4 on a centos system.<br>
<br>
Suppose I have a cluster I want to stand up and want to make it easy without having to copy the cookie file to all the nodes.<br>
<br>
If I run as rabbitmq the command: rabbitmq-server -setcookie pigcat &<br>
It appears to start fine however I have noticed a couple of things.<br>
the .erlang_cookie doesn't update.<br>
<br>
If I later run rabbitmqctl cluster_status I can't to communicate with the node because I cannot set the cookie to my desired cookie.<br>
<br>
So the question is, how does one effectively maintain a cluster using the -setcookie option?<br>
<br>
I tried looking at the rabbitmqctl and rabbitmq-server script files but none of them hit the erl application directly. In the docs it briefly mentions one could modify the scripts so that erl is started with a specific cookie.<br>
I'd like to be able to do this but do not see where it would be that I need to augment so I can ensure the cookie is always set to a known value when accessing the node.<br>
<br>
Does anyone have an example of how / what scripts need to be modified?<br>
<br>
Thanks in advance.<br>
<br>
