[4] Add Data into Database and start Nova services.
It doesn't need to care the messages "deprecated ***" when sync DB.
root@dlp ~(keystone)#
su -s /bin/bash placement -c "placement-manage db sync"
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage api_db sync"
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage cell_v2 map_cell0"
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage db sync"
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage cell_v2 create_cell --name cell1"
root@dlp ~(keystone)#
systemctl restart nova-api nova-conductor nova-scheduler nova-novncproxy

root@dlp ~(keystone)#
systemctl enable nova-api nova-conductor nova-scheduler nova-novncproxy

root@dlp ~(keystone)#
systemctl restart apache2 nginx
# show status

root@dlp ~(keystone)#
