Using PHP-FPM (FastCGI Process Manager) to run web pages and web applications has many advantages, especially when compared to older techniques such as PHP running as an Apache module. One of the most important benefits is that PHP-FPM significantly improves performance and scalability by allowing finer-grained management and optimization of PHP processes. In this way, we can use the server's resources more efficiently, reduce the response time, and our system can remain stable even in the event of heavy traffic. However, over time, the PHP versions of our web applications may become outdated, which the various control panels do not update. In this description, we will see in a few steps how we can easily modify our manual settings so that our websites and web applications also work with the correct PHP version.

In this description, we will install the PHP 8.2 version on a Debian system, set the default PHP versions, set it as an optional PHP version in the ISPConfig control panel, set it in the required storage locations and finally check the PHP operation on a Drupal and a WordPress site.

Another era has come again, when our Debian 10 (Buster) server has also run out of time, and it has become a burning task to do something about this problem. In this tutorial, we will upgrade a perfect Debian 10 (Buster) server to Debian 11 (Bullseye). On this page, we review the necessary tasks before the update, which we use to prepare our system for the new main version.

With the help of the ISPConfig control panel, we can easily manage the websites on our server, as well as other web services. In this description, we will review how to build and provision our ISPConfig3 server, as well as how to set up free SSL certificates issued by Let's Encrypt for the control panel, main services and our websites. On this page, we will install the basic system, the ISPConfig control panel with the necessary components, and then check the existing web interfaces and services.

With the help of LAMP systems, we can run dynamic websites on our server or even on our home computer. In this description, we will create a LAMP server on the Debian 11 (Bullseye) operating system, on which the following components will be installed: Apache 2.4.54, MariaDB 10.5.15, PHP 7.4 and phpMyAdmin 5.0.4, UFW firewall.

When we run websites, our server and the websites and services that run on it are often vulnerable to external attacks, and our MySQL / MariaDB database server is no exception. If the Fail2Ban protection software is also available on your server, this short description will show you how to make your server more secure against attacks on your "Access denied for user root @ ip address (using password: YES / NO)" database server.

The operating system running on our Debian-based web servers will become obsolete over time, so over time it will be necessary to completely upgrade the distribution. In this description, we will perform a complete upgrade of a Debian 9 (Stretch) web server to Debian 10 (Buster). There are many features on the server that will also be updated. On the first page of this description, we will perform the pre-upgrade steps to prepare your system for a secure upgrade.
