[rabbitmq-discuss] unable to connect to node

Wed Nov 28 18:42:56 GMT 2012

Thanks Tim.  There seem to be a couple of problems re: the RPM
install, but the "unable to connect to node" appears to be related to
relocating the SYS_PREFIX outside the install directory.  In other
words:

1) I stopped the server started by the init.d script and killed the
epmd process manually to get a clean start
2) install the rabbitmq-server-generic-unix-3.0.0.tar.gz, modifying
rabbitmq-defaults to set SYS_PREFIX to a directory other than the
install directory.
3) started the server
4) same problem with the status reporting "unable to connect to node".
Also found that I was unable to install a plugin getting the error:
           Error: {cannot_read_enabled_plugins_file,
           "/data/rabbitmq/etc/rabbitmq/enabled_plugins",eisdir}

5) stopped the server with "rabbitmqctl stop"
6) unset the custom SYS_PREFIX in rabbitmq-defaults and restarted the server
7) started the server and not status reports normally

The init.d script packaged in the RPM is removing the
/var/run/rabbitmq directory on stopping and not re-creating it on
startup, but that's a different issue...

So, do you know of any reason why relocating the data (log, mnesia,
enabled_plugins) should be any different that simply changing the
SYS_PREFIX in rabbitmq-defaults?

Anyway, are you sure that the rabbitmq-server process is running? You should see an instance of 'beam.smp' when running `ps` if it is, or alternatively you can run `epmd -names` as any user to see which erlang nodes are up and running.
