Next you need to set up the service that runs the Nominatim frontend. This is
easiest done with a systemd job.
+First you need to tell systemd to create a socket file to be used by
+hunicorn. Create the following file `/etc/systemd/system/nominatim.socket`:
+
+``` systemd
+[Unit]
+Description=Gunicorn socket for Nominatim
+
+[Socket]
+ListenStream=/run/nominatim.sock
+SocketUser=www-data
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Now you can add the systemd service for Nominatim itself.
Create the following file `/etc/systemd/system/nominatim.service`:
``` systemd
[`NOMINATIM_API_POOL_SIZE`](../customize/Settings.md#nominatim_api_pool_size)
connections to the database to serve requests in parallel.
-Make the new service known to systemd and start it:
+Make the new services known to systemd and start it:
``` sh
sudo systemctl daemon-reload
-sudo systemctl enable nominatim
-sudo systemctl start nominatim
+sudo systemctl enable nominatim.socket
+sudo systemctl start nominatim.socket
+sudo systemctl enable nominatim.service
+sudo systemctl start nominatim.service
```
This sets the service up, so that Nominatim is automatically started
