This just uses the development server for testing purposes. For production environments you should probably go with a more robust solution, like [gunicorn](web-server/Running-PowerDNS-Admin-with-Systemd,-Gunicorn--and--Nginx.md) or a WSGI server.
After saving the file, we need to reload the systemd daemon:
> sudo systemctl daemon-reload
We can now try to start the service:
> sudo systemctl start powerdns-admin
If you would like to start PowerDNS-Admin automagically at startup enable the service:
> systemctl enable powerdns-admin
Should the service not be up by now, consult your syslog. Generally this will be a file permission issue, or python not finding it's modules. See the Debian unit example to see how you can use systemd in a python `virtualenv`
