In this tutorial we will install a minimal Debian 9 (Stretch) server, which will serve as a basis for future perfect server tutorials. On this page, we download the Debian 9 (Stretch) installation package, and during the installation, we configure the language and locale, configure the network, create the first user, configure disk partitions and the APT package manager. On the second page of the description, we will continue with the rest of the installation.

In this description, we force our Linux system to play our old midi music with our favorite media player programs, such as Audacious or VLC Player, or we can even launch them from the command line.

In this tutorial we use our SSL certificate issued by Let's Encrypt to provide our ISPConfig control panel on the server, as well as Postfix, Dovec and PureFTPd services. We will also create our auto-renewal script for these.

In this tutorial, we will install Let's Encrypt Certbot on an ISPConfig3 server environment. Once the installation is complete, our system is ready to obtain and automatically configure and renew free SSL certificates for server-managed domain names so that any web site we manage can be operated over the secure HTTPS protocol with a few clicks.
