[](#launch)

- `php src/app.php name.json` - where `name.json` argument is any config, placed at `config` folder

### Autostart

[](#autostart)

Launch server as the `systemd` service

You can create as many servers as wanted by providing separated config for each instance!

Following example require `npsapp` installed into the home directory of `npsapp` user (`useradd -m npsapp`)

```
# /etc/systemd/system/npsapp.service

[Unit]
After=network.target

[Service]
Type=simple
User=npsapp
Group=npsapp
ExecStart=/usr/bin/php /home/npsapp/npsapp/src/app.php name.json
StandardOutput=file:/home/npsapp/debug.log
StandardError=file:/home/npsapp/error.log
Restart=on-failure

[Install]
WantedBy=multi-user.target
```

- `sudo systemctl daemon-reload` - reload systemd configuration
- `sudo systemctl enable npsapp` - enable `npsapp` service on system startup
- `sudo systemctl start npsapp` - start `npsapp` server

Proxy
-----

[](#proxy)

Like [NEX Protocol](https://nightfall.city/nex/info/specification.txt), NPS data could be simply forwarded using any proxy server that support TCP streams

### Nginx

[](#nginx)

```
# /etc/nginx/nginx.conf

stream {
        server {
                listen 1915;
                proxy_pass 127.0.0.1:1915;
        }
}

```

- `ncat 127.0.0.1 1915`
- `telnet 127.0.0.1 1915`
