&gt; I&#39;m trying to set up clustering on AWS EC2 but I&#39;m running into problems just getting the basic setup.<br>
&gt;<br>
&gt; Setup:<br>
&gt; -I have the appropriate ports open, and I can connect to them via. telnet<br>
<br>
Which ports have you opened? It&#39;s not just 5672 that is needed for clustering.<br>
<br>
&gt;<br>
&gt; When I telnet to rabbit1:5672 there is an entry in rabbit1s log files, but when I join_cluster, nothing shows up.<br>
&gt;<br>
<br>
That doesn&#39;t make any sense. Presumably you mean &quot;when I ssh to rabbit1&quot; instead? Do both rabbit recognise one another&#39;s host names (via /etc/hosts or whatever)?<br>
<br>
Running `rabbitmqctl status` on both nodes (locally) can you confirm that the cookie hashes are indeed the same?<br>
<br>
Cheers,<br>
Tim<br>
