\"Mascote<\/p>\n

Note (2026):<\/strong> the four videos are from 2016\u20132017 and use Debian 8, openSUSE, Ubuntu 16.04, and CentOS 7 \u2014 all out of support today. The videos remain online and are useful for their method<\/em>: partitioning, package selection, networking, and initial access have changed very little. What has changed is which version to install, and that is covered just below.<\/div>\n

This series walks through installing four distributions in server mode, intended as the foundation of a web hosting environment \u2014 the base on which you later install ISPConfig<\/a>.<\/p>\n

<\/p>\n

What to install in 2026<\/h2>\n

If you are setting up a server today, start here instead of repeating the versions in the videos:<\/p>\n\n\n\n\n\n\n\n\n
Family<\/th>\nCurrent version<\/th>\nSupported until<\/th>\n<\/tr>\n<\/thead>\n
Debian<\/td>\n13 (Trixie)<\/strong><\/td>\nJune 2030<\/td>\n<\/tr>\n
Ubuntu Server<\/td>\n26.04 LTS<\/strong><\/td>\nMay 2031<\/td>\n<\/tr>\n
AlmaLinux \/ Rocky Linux<\/td>\n10<\/strong><\/td>\nMay 2035<\/td>\n<\/tr>\n
openSUSE Leap<\/td>\n16.0<\/strong><\/td>\nOctober 2027<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Two changes in direction since the recordings deserve an explanation:<\/p>\n

The CentOS in the video no longer exists.<\/strong> CentOS 7 ended on June 30, 2024, and CentOS 8 died earlier, in December 2021 \u2014 Red Hat shortened its lifecycle and turned the project into CentOS Stream, which is upstream<\/em> of RHEL rather than a stable copy of it. Anyone who wants what CentOS used to be \u2014 a free, binary-compatible rebuild of RHEL \u2014 now installs AlmaLinux<\/strong> or Rocky Linux<\/strong>. The commands in the video still apply to both: it is the same family, with dnf<\/code> in place of yum<\/code>.<\/p>\n

The Debian installer changed its appearance, not its logic.<\/strong> The screens in the video show the classic debian-installer<\/code> . It is still there, and the decisions are the same: partitioning, root password, task selection. In Debian 13, the new feature is the alternative graphical installer (Calamares) on the live image \u2014 netinst, which is what matters for servers, remains the same.<\/p>\n

When installing a server<\/h2>\n

Regardless of the distribution, four decisions determine whether you will struggle later:<\/p>\n

    \n
  • Do not install a desktop environment.<\/strong> In task selection, check only the SSH server and system tools. A server with a desktop consumes RAM that should belong to the database and increases the attack surface.<\/li>\n
  • Plan partitioning beforehand.<\/strong> For hosting, separate \/var<\/code> \u2014 that is where sites, databases, and logs live. A log that fills the root partition brings down the entire system; a log that fills a separate partition only brings down logging.<\/li>\n
  • Static IP and FQDN hostname.<\/strong> Hosting and email servers need a fully qualified name (servidor.seudominio.com.br<\/code>) that resolves correctly, with a reverse DNS record. That is the subject of the post Getting to Know DNS<\/a>.<\/li>\n
  • SSH key before closing the door.<\/strong> Configure key-based access and test it in a second session before disabling passwords \u2014 the walkthrough is in SSH authentication keys<\/a>.<\/li>\n<\/ul>\n

    Once installation is complete, the panel goes on top: the ISPConfig autoinstaller<\/a> sets up Apache or Nginx, MariaDB, Postfix, Dovecot, and the rest of the hosting stack.<\/p>\n

    The videos in the series<\/h2>\n

    Debian Server<\/h3>\n

    First video in the series: a walkthrough of installing Debian 8.5 64-bit, intended as the foundation of a web hosting server capable of hosting systems in Java, PHP, Perl, Python, and Go. Debian 8 images were removed from cdimage.debian.org<\/code> \u2014 to follow along today, download the netinst image for current Debian<\/a>.<\/p>\n
