I was following the tutorials on Openstack docs website for a minimal deployment of the Stein release (I am installing it on Ubuntu 18.04 instances). I installed the nova services and made the required configuration. Then I reached this stage and ran the following command on the controller node.
openstack compute service list --service nova-compute
I was expecting to see a nova-compute service running on a compute host as the result, but I get nothing.
I looked at the nova-compute.log file on my comupte node (/var/log/nova/nova-compute)
and I have this error:

Apparently, it has a problem connecting to the rabbitmq service. I searched a lot but I couldn't find anything of use in my case. I've been stuck on this for quite some time now. I'd be very happy if someone could give me an answer.
