[rabbitmq-discuss] Clustering Off LAN isn't working

Wed Apr 15 05:51:12 BST 2009

Hi

I've setup a cluster on my LAN (finally) and got it working by modifying the
startup script for rabbitmq-server (yuk) to set the cookie.  Then setup
/etc/rabbitmq/rabbitmq.conf to set the cookie:

CTL_ERL_ARGS="-setcookie mycookie"

On the lan:

$ sudo rabbitmqctl -n rabbit at ubi status
Status of node rabbit at ubi ...
[{running_applications,[{rabbit,"RabbitMQ","1.5.4"},
                        {mnesia,"MNESIA  CXC 138 12","4.4.3"},
                        {os_mon,"CPO  CXC 138 46","2.1.6"},
                        {sasl,"SASL  CXC 138 11","2.1.5.3"},
                        {stdlib,"ERTS  CXC 138 10","1.15.3"},
                        {kernel,"ERTS  CXC 138 10","2.12.3"}]},
 {nodes,[rabbit at ubi,rabbit at hassox]},
 {running_nodes,[rabbit at ubi]}]
...done.

Over the Interwebs:

$ sudo rabbitmqctl -n rabbit at ubinet status
Status of node rabbit at ubinet ...
{badrpc,nodedown}
...done.

Where ubinet is setup in my hosts file.  If I use a full IP address:

 $ sudo rabbitmqctl -n rabbit at 123.456.789.123 status
Status of node 'rabbit at 123.456.789.123' ...

=ERROR REPORT==== 15-Apr-2009::14:50:00 ===
** System NOT running to use fully qualified hostnames **
** Hostname 123.456.789.123 is illegal **
{badrpc,nodedown}
...done.

IP addy changed...

Any idea on why this would cause an issue?  I can't find any documentation
on it on the rabbit site at all :(

Cheers
