Hi,

I'm installing OpenStack on two nodes. One as controller, network and compute, the other just as compute node. According to the document of Rocky, I installed all modules on the controller node and all became verified. At the next step, I configure the compute node and set the configurations according to the document, but when I start the service openstack-nova-compute it just logs:

compute.pps.wams systemd[1]: Starting OpenStack Nova Compute Server...

and it never start!

In the logs of nova-compute it just writes one line:

2018-11-25 15:53:56.730 1246 INFO os_vif [-] Loaded VIF plugins: ovs, linux_bridge, noop

I should tell that I don't config and install Neutron, yet because the documentation suggested installing components according to the list order. What could be the problem?

Can you verify that no other nova-compute process is running? try ps alx | grep nova and kill respective process(es) if necessary. Try running the command manually /usr/bin/python /usr/bin/nova-compute and watch log files (nova-compute.log, syslog) for issues.

In my case, it was because of faulty Rabbitmq. Check the Rabbitmq logs and ensure it works properly.

I am also seeing the same issue. The last line in nova-compute.log is the same as reported. I've tried adding the compute node by following the https://docs.openstack.org/nova/rocky/install/compute-install-rdo.html (Rocky OpenStack instructions) and by trying to apply PackStack answer file with the exact same result. There isn't an error in the controller node's RabbitMQ logs and there are no discernable errors in any of the compute node's logs.

When running /usr/bin/nova-compute --debug the same behavior is observed.

Hi,

I got the same problem. I checked the rabbitmq log and did not find errors. Is there alternative troubleshooting or solutions? Thanks.

I have exactly the same problem and I can not find a solution anywhere. I hope someone shares useful information about it.

Thanks.

Disable firewalld on the controller node

I have the same behavior following the deployment process for Rocky. It's a 4 node (controller + 3 compute) running Centos 7.
