[4] データベースにデータを追加して Trove サービスを起動します。
root@network:~#
su -s /bin/bash trove -c "trove-manage db_sync"

root@network:~#
systemctl restart trove-api trove-taskmanager trove-conductor nginx

root@network:~#
systemctl enable trove-api trove-taskmanager trove-conductor
[5] Control ノードでステータスを確認します。エラーが表示されなければ OK です。
root@dlp ~(keystone)#
apt -y install python3-troveclient
root@dlp ~(keystone)#
