**NOTE**: if you run on Debian, replace `yum` with `apt`.

This document describes how to switch to using the VPN daemon to control 
OpenVPN processes. 

We assume you setup your current VPN server using `deploy_${DIST}.sh` and have 
everything on one machine.

Enabling the daemon is rather simple:

    $ sudo yum -y install vpn-daemon
    $ sudo systemctl enable --now vpn-daemon

Modify `/etc/vpn-server-api/config.php` and add the configuration key 
`useVpnDaemon` and set its value to `true` in the "root", i.e. on the same 
level as `vpnProfiles`, e.g.:

    <?php

    return [

        'useVpnDaemon' => true,

        // List of VPN profiles
        'vpnProfiles' => [
            'internet' => [
                // The number of this profile, every profile per instance has a 
                // unique number
                // REQUIRED
                'profileNumber' => 1,

                // ...

Make sure everything still works, i.e. you can see connected clients when 
visiting the "Connections" tab in the portal, or use `vpn-server-api-status` to
check the "load" of the OpenVPN processes for each profile, for example:

```
$ sudo vpn-server-api-status --json
[
    {
        "profile_id": "amsterdam",
        "active_connection_count": 110,
        "max_connection_count": 488,
        "percentage_in_use": 22,
        "port_client_count": {
            "udp/1194": 17,
            "udp/1195": 20,
            "udp/1196": 29,
            "udp/1197": 23,
            "tcp/443": 9,
            "tcp/1194": 5,
            "tcp/1195": 3,
            "tcp/1196": 4
        }
    }
]
```
