[rabbitmq-discuss] Can't cluster nodes on a single machine

Sun May 20 01:53:45 BST 2012

Ishwor, thanks for the quick response. The fab file you suggested helps 
setting up a cluster on different machines where each node is named 
"rabbit". My question is about a cluster running two RabbitMQ nodes on 
the same machine with custom node names. I'm following the same sequence 
of commands (stop_app, reset, cluster, start_app), but the cluster step 
fails to find the other node.
