在控制節點上安裝nova元件完成後，以如下方式啟動時：
[root@controller ~]# systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstaci-nova-novncproxy.service
failed to execute operation: no such file or directory
於是我把它每個單獨啟動：
[root@controller ~]# systemctl enable openstack-nova-api.service
created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-api.service to /usr/lib/systemd/system/openstack-nova-api.service.
[root@controller ~]# systemctl enable openstack-nova-consoleauth.service
failed to execute operation: no such file or directory
[root@controller ~]# systemctl enable openstack-nova-scheduler.service
created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-scheduler.service to /usr/lib/systemd/system/openstack-nova-scheduler.service.
[root@controller ~]# systemctl enable openstack-nova-conductor.service
created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-conductor.service to /usr/lib/systemd/system/openstack-nova-conductor.service.
[root@controller ~]# systemctl enable openstack-nova-novncproxy.service
created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-novncproxy.service to /usr/lib/systemd/system/openstack-nova-novncproxy.service.
經過在網上查詢得知，nova-consoleauth從18.0.0版後就被棄用了。因此，想要啟動nova服務只需要
[root@controller ~]# systemctl start openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
就可以了。
