[rabbitmq-discuss] possible bug starting rabbit with NODENAME set?

Thu May 15 17:41:56 BST 2008

rabbitmq-server 1.3.0, Debian Etch, erlang version doesn't seem to matter (R12B-2 and R11B-5)

When NODENAME is set to something other than "rabbit" in /etc/default/rabbitmq, 
`/etc/init.d/rabbitmq start` always fails (while broker is actually started)




My temporary fix is this (startup will take some time to allow the original start to time 
out):

Also, note rabbitmqctl behavior looked erroneous to me (but my expectation might be wrong 
here - I thought when NODENAME was set in /etc/default/rabbitmq, I didn't need to 
explicitly set -n):

# rabbitmqctl status
Status of node rabbit at host1 ...
{badrpc,nodedown}
done.

# rabbitmqctl -n wabbit status
Status of node wabbit at host1 ...
