On the control node (ct), do the following

Confirm that there is a computing host in the database

. Admin-openrc

Openstack compute service list-service nova-compute

Discover compute node hosts

Su-s / bin/sh-c "nova-manage cell_v2 discover_hosts-verbose" nova

When you add new compute nodes later, you must run "su-s / bin/sh-c" nova-manage cell_v2 discover_hosts-- verbose "nova" on the controller node to register these new compute nodes.

Set the appropriate discovery interval (optional)

Vim / etc/nova/nova.conf

[scheduler]

Discover_hosts_in_cells_interval = 300

Systemctl restart openstack-nova-api.service

Verify the entire computing service nova

. Admin-openrc

Openstack compute service list

Openstack catalog list

Openstack image list

Nova-status upgrade check

The last screen appears. Congratulations, the installation of OpenStack is half complete. There are many potholes in the following neutron, horizon and startup instances. O (∩ _ ∩) o
