[rabbitmq-discuss] rabbitmq nodedown error

[Tim Watson]

Guys,

The erlang.cookie needs to be getting picked up from the same place, so if the account that runs rabbitmqctl is picking up the cookie from a different file (or not at all) then the rabbitmqctl node won't be able to connect to the other node (on which the broker is running).

The cookie is often located in /var/lib/rabbitmq/.erlang.cookie on unix based installs, though that may differ if you've installed via macports which I can see Terry has. Terry I'd suggest looking for the .erlang.cookie file beneath /opt/local - if you look at the broker logs I'm pretty sure you'll see that the home directory is not /Users/terry and erlang will look in $HOME/.erlang.cookie so if you figure out where macports has put this and copy it to your home directory, you should be ok.

Same should go for you pi, though obviously minus the /opt/local prefix.

Cheers,
Tim
