greeting everyone, I am configuring a compute node (nova) with OpenStack. When I try to enable the node I get multiple error with epmd , Erlang port mapper and mcelog. I've searched online and tried some solutions but not luck, plus the info on some of the errors is low. I would appreciate if some one can walk me through this issue so I understand what was done wrong and what to do to fix it. Bellow is the log ext and error I get.

enter image description here

  • Which guide did you follow to install? How does your rabbitmq and epmd config look like? – eblock Dec 22 '21 at 08:39

    You'll need to configure epmd, possibly in `/etc/sysconfig/erlang` and it should map your rabbitmq settings. The guide does not cover that, I've had to figure this out from time to time what exactly the system requires. For example, the file could look like this: `EPMD_ADDRESSES="127.0.0.1" EPMD_PORT="4369"` – eblock Dec 22 '21 at 17:50
