}
[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 enable --now openstack-trove-api openstack-trove-taskmanager openstack-trove-conductor

[root@network ~]#
systemctl restart nginx
[5] Firewalld を有効にしている場合は、サービスポートの許可が必要です。
[root@network ~]#
firewall-cmd --add-port=8779/tcp

success
[root@network ~]#
firewall-cmd --runtime-to-permanent

success
[6] 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。
