[Nginx] Help installing kerberos.io

Hi so I have worked before with Nginx but I cannot figure out why this keeps happening. I am trying to install kerberos.io which is a DIY camera streaming program that uses PHP and Nginx for the webserver. The documentation is listed here: https://doc.kerberos.io/2.0/installation/Raspbian

The main problem is that when I get up to the Nginx configuration I am lost it looks like this:

server
{
    listen 80 default_server;
    listen [::]:80 default_server;


    root /var/www/web/public;
    index index.html index.htm index.nginx-debian.html;


    server_name kerberos.rpi kerberos.rpi;
    index index.php index.html index.htm;


    location /
    {
            autoindex on;
            try_files $uri $uri/ /index.php?$query_string;
    }


    location ~ \.php$
    {
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
    }
}

For some reason Nginx doesn't start even though I modify it to use port 82 since I am running Pydio on port 81. If anyone here can tell me if OMV uses a custom Nginx and help me out I would appreciate it. I am using a Raspberry Pi 3 Model B with OMV Erasmus (sourceforge pre-made image)
