[1] Install Magnum services on Network Node. For questions during the installation, it's OK with [No] to All.
root@network:~#
apt -y install magnum-api magnum-conductor python3-magnumclient
[2] Configure Magnum.
root@network:~#
mv /etc/magnum/magnum.conf /etc/magnum/magnum.conf.org

root@network:~#
vi /etc/magnum/magnum.conf
# create new

root@network:~#
chmod 640 /etc/magnum/magnum.conf

root@network:~#
chgrp magnum /etc/magnum/magnum.conf

root@network:~#
mkdir /var/lib/magnum/{tmp,certificates}

root@network:~#
chown magnum. /var/lib/magnum/{tmp,certificates}

[3] Configure Nginx for proxy settings.
root@network:~#
vi /etc/nginx/nginx.conf
# add into the [stream] section

stream {
    upstream neutron-api {
        server 127.0.0.1:9696;
    }
    server {
        listen 10.0.0.50:9696 ssl;
        proxy_pass neutron-api;
    }
    upstream magnum-api {
        server 127.0.0.1:9511;
    }
    server {
        listen 10.0.0.50:9511 ssl;

    }
    ssl_certificate "/etc/letsencrypt/live/network.srv.world/fullchain.pem";
    ssl_certificate_key "/etc/letsencrypt/live/network.srv.world/privkey.pem";
}
[4] Add Data into Database and start Magnum services.
root@network:~#
su -s /bin/bash magnum -c "magnum-db-manage upgrade"

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

[5] Verify Magnum status on Control Node. It's OK if state is [up].
Also Create a Cinder volume type configured in [magnum.conf].
