location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

The crescendo swells as Nginx is beckoned to embrace these changes.

bash
sudo systemctl restart nginx

The symphony nears its zenith as the server undergoes a reboot, a rite of passage that solidifies the integration of the components into a cohesive whole.

bash
sudo systemctl restart php7.2-fpm

In the quest for a holistic web server experience, one cannot overlook the indispensable role of the firewall, a digital guardian that regulates traffic to the server. Unveil the gates to HTTP and HTTPS traffic with the grace of the UFW (Uncomplicated Firewall) command.

bash
sudo ufw allow 'Nginx Full'

The journey concludes with the triumphant act of enabling the UFW to bear the standard of protection.

bash
sudo ufw enable
