In the final part of our Debian 11 to 12 upgrade process, we focus on resolving the deepest technical challenges and reviving services. We take a detailed look at how to fix a stubborn Grub/OpenSSL issue that was blocking package management using a unique "Dummy Script" trick. Next comes fine-tuning the server environment: setting the system's default PHP versions, then running the ISPConfig upgrade script to restore website and control panel availability, correcting Apache configuration changes. Finally, we verify phpMyAdmin functionality and fix the Roundcube webmail 404 error, completing the system's operation in the new Debian 12 environment.

Encyclopedia - Nginx HTTP Server | Linuxportal
Nginx is an open source, high-performance web server that goes far beyond its traditional role. It also functions as a reverse proxy, load balancer, and HTTP cache, making it a cornerstone of modern web infrastructure. Its popularity is due to its unique, event-driven, and asynchronous architecture, which allows it to handle tens of thousands of simultaneous connections with minimal resource consumption. The software was developed by Igor Sysoev to solve the C10k problem, and has received key improvements over its history, such as support for HTTP/2 and dynamic modules. This encyclopedia entry provides a detailed introduction to Nginx's master-worker process model, hierarchical configuration system, and key uses. Finally, we compare it with Apache HTTP Server, highlighting key differences in performance, configuration, and flexibility.

How to manually change the PHP version of a website or web application running in a PHP-FPM pool? | Linux portal
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 However, over time, the PHP versions of our web applications may become outdated, which the various control panels do not update.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.
