[6]	Nginx にプロキシの設定を追加します。

root@network:~#

vi /etc/nginx/nginx.conf

# [stream] セクション内に追記

stream {
    upstream neutron-api {
        server 127.0.0.1:9696;

    ssl_certificate_key "/etc/letsencrypt/live/network.srv.world/privkey.pem";
}

[7]	データベースにテーブルを作成して Gnocchi サービスを起動します。

root@network:~#

root@network:~#

a2enmod wsgi

root@network:~#

a2enmod ssl

root@network:~#

root@network:~#

systemctl disable --now aodh-api

root@network:~#

systemctl restart aodh-evaluator aodh-notifier aodh-listener apache2

root@network:~#

systemctl restart nginx

[10]	Control ノードで動作確認します。
