<span>OK, I realize this is probably a very basic thing, but I've been</span><br><span>googling and screwing around with this for hours and getting nowhere.</span><br><br><span>I'm trying to set up my first rabbitmq cluster. I have it installed</span><br>
<span>fine on two ec2 hosts, and I'm trying to get one to cluster with the</span><br><span>other. I've tried the instructions at</span><br><br><a href="http://www.rabbitmq.com/clustering.html" target="_blank">http://www.rabbitmq.com/clustering.html</a><br>
<br><span>and I keep getting</span><br><br><span>Error: unable to connect to node 'rabbit@rabbitmq-small02-dev':</span><br><span>nodedown</span><br><span>diagnostics:</span><br>
<span>- nodes and their ports on rabbitmq-small02-dev: [{rabbit,57641},</span><br><br><span>{rabbitmqctl12928,46801}]</span><br><span>- current node: 'rabbitmqctl12928@rabbitmq-</span><span>small02-dev'</span><br>
<span>- current node home dir: /var/lib/rabbitmq</span><br><span>- current node cookie hash: 4IHR1JMCSCh55g/tisBydg==</span><br><br><span>So I found more detailed instructions on�</span><a href="http://skaag.net/" target="_blank">skaag.net</a><span>,</span><span>�at</span><br>

<span>the second machine, according to the instructions for ec2.</span><br>
<br><span>Then I go through the instructions.</span><br><br><span>I stop the server:</span><br><span>[jstoner@rabbitmq-small02-dev]</span><span>> service rabbitmq-server stop</span><br>
<span>Stopping rabbitmq-server: RabbitMQ is not running</span><br><span>rabbitmq-server.</span><br><br><span>I change the cookie to the same as the other one:</span><br><span>[jstoner@rabbitmq-small02-dev]</span><span>> sudo su</span><br>
<span>root@rabbitmq-small02-dev:/</span><span>home/jstoner/rclient# echo -n [cookie-text]</span><br><span>> /var/lib/rabbitmq/.erlang.</span><span>cookie</span><br><span>root@rabbitmq-small02-dev:/</span><span>home/jstoner/rclient# exit</span><br>
<span>exit</span><br><br><span>I try to restart:</span><br><span>[jstoner@rabbitmq-small02-dev]</span><span>> sudo service rabbitmq-server start</span><br><span>Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/</span><br>
<span>startup_{log, _err}</span><br><span>rabbitmq-server.</span><br><br><span>I look at the logs they mention:</span><br><span>[jstoner@rabbitmq-small02-dev]</span><span>> more /var/log/rabbitmq/startup_log</span><br>

<br><span>That tells me nothing I can make sense of. So I see what happens if I</span><br><span>try the next step:</span><br><span>[jstoner@rabbitmq-small02-dev]</span><span>> sudo rabbitmqctl stop_app</span><br>
