[rabbitmq-discuss] Clustering and rabbitmqctl hangs

Fri May 4 14:25:32 BST 2012

Oops, right I needed the next set of commands:

RABBITMQ_NODE_PORT=5672 RABBITMQ_NODENAME=rabbit1 
RABBITMQ_SERVER_START_ARGS="-rabbitmq_mochiweb listeners 
[{mgmt,[{port,55672}]}]" rabbitmq-server -detached
RABBITMQ_NODE_PORT=5673 RABBITMQ_NODENAME=rabbit2 
RABBITMQ_SERVER_START_ARGS="-rabbitmq_mochiweb listeners 
[{mgmt,[{port,55673}]}]" rabbitmq-server -detached
RABBITMQ_NODE_PORT=5674 RABBITMQ_NODENAME=rabbit3 
RABBITMQ_SERVER_START_ARGS="-rabbitmq_mochiweb listeners 
[{mgmt,[{port,55674}]}]" rabbitmq-server -detached

To set up the monitoring as well!
