OpenStack Train version of dual-node installation (8) Discovery of compute nodes and verification of nova installation

Part 8: discovering compute nodes and verifying the installation of nova

Do the following on the control node (ct) to discover the configured compute node (C1)

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
