[rabbitmq-discuss] Unable to get automatic clustering to work

Fri Jan 14 00:29:55 GMT 2011

OK, still can't seem to get this working reliably.

I was able to get a fresh install onto two servers to come up fine
clustered together.  Woot!

Tried to do the same thing with four servers and only the first one
comes up; the others complain about bad cookies in table definition.
If I'm interpreting the log output correctly (big if), each node
thinks it's in a cluster by itself; but they all have the same
rabbitmq_cluster.conf file listing all four nodes.  I purged the
rabbitmq-server install to make sure there wasn't any data lingering
around from a previous config, but it still doesn't work.  Sample
startup log below.  Any help appreciated.

Starting all nodes...
