Starting neutron-server

Before the neutron-server service can be started, the Neutron database must be updated based on the options we configured earlier in this chapter. Use the neutron-db-manage command on the controller node to update the database accordingly:

    # su -s /bin/sh -c "neutron-db-manage     --config-file /etc/neutron/neutron.conf     --config-file /etc/neutron/plugins/ml2/ml2_conf.ini     upgrade head" neutron

Restart the Nova compute services on the controller node:

    # systemctl restart nova-api nova-scheduler nova-conductor

Restart the Nova compute service on the compute nodes:

    # systemctl restart nova-compute

Lastly, restart the neutron-server service on the controller node:

    # systemctl restart neutron-server
