Hi. <br><br>I am trying to create a cluster of three RabbitMQ nodes.<br>I am having trouble setting the ".erlang.cookie" file correctly.<br><br>Node1 - x.y.z.28 - Ubuntu 12.04 - RabbitMQ installed from repositories.<br>
Node2 - x.y.z.38 - Ubuntu 12.04 - RabbitMQ installed from repositories. <br>Node3 - x.y.z.39 - Ubuntu 12.04 - RabbitMQ installed from repositories. <br><br>Individually all the three nodes are working fine.<br clear="all">
<br>Step 1 : copy the erlang magic cookie between the nodes<br><ul><li>I replace the /var/lib/rabbitmq/.erlang.cookie file in Node 2 with that of Node 1</li><li>ls -al shows the file is owned by "rabbitmq" user</li>
</ul>step 2 : I try to add Node2 to a cluster with Node1<br><ul><li>Every rabbitmqctl command fails like below</li></ul><font style="color:rgb(51,0,0)" size="2"><span style="font-family:courier new,monospace">root@rabbit3:/home/aravindh# rabbitmqctl cluster <a href="mailto:rabbit@130.127.39.28">rabbit@130.127.39.28</a></span><br style="font-family:courier new,monospace">
