The Matomo (formerly Piwik) web analytics system is a high-quality statistical tool that provides us with a detailed and comprehensive view of our website traffic. I have previously described how to install and deploy Matomo software on your own server, and in this tutorial we will review how to upgrade your web analytics system to the recently released 4.x major version. The web statistics program also contains many new features, but in this description we do not focus on these, but we satisfy the software requirements for the new main version so that the system can continue to operate stably. On this page we will make the necessary settings before the update and update Matomo.

With the help of LAMP systems, we can run dynamic web pages on our server or even on our home computer. I have previously built LAMP servers for Debian 8 (Jessie), Debian 9 (Stretch) and Ubuntu 18.04 LTS (Bionic Beaver), and in this description we will install the LAMP server components for the Ubuntu 20.04 LTS (Focal Fossa) Linux distribution.

ImageMagick is a free and open source, cross-platform software package designed primarily for displaying, creating, converting, modifying, and editing raster images, but can also handle a variety of vector formats such as EPS (Encapsulated PostScript), AI (Adobe Illustrator) , PDF (Portable Document Format), etc. In total, it supports more than 200 image file formats. And Imagick is a native PHP extension that allows you to manage different image formats in a web environment using the ImageMagick API. In this quick troubleshooter, we take a look at how to fix errors from the software security policy with a little intervention.

If you run multiple websites on your server, you may need to run a different version of PHP for each website. When using ISPConfig, this is a very simple task, as the control panel can run multiple versions of PHP at the same time. In this tutorial, we will review how to configure PHP instances installed on a server in FastCGI and PHP-FPM modes.

With the help of LAMP systems, we can run dynamic web pages on our server or even on our home computer. In this description, we create a LAMP server for Debian 10 (Buster) with the following components: MariaDB 10.3.18, Apache 2.4.38, PHP 7.3 and phpMyAdmin 4.9.1. On this page we install the Apache, MariaDB and PHP components.

The official repository for Debian 9 (Stretch) has PHP 7.0.x, which is a bit out of date, and you won't receive any updates. Therefore, we may need newer versions if we run live websites, but we can even expand our test environment. In this description, we will conveniently install several versions of PHP using the deb.sury.org external repository, which can be run side-by-side on our Debian-based servers using the PHP-FPM server API.
