Introduction Deploying set up s3fs fuse mount on a Debian 13 Trixie machine is straightforward thanks to Debian’s policy-compliant packaging. Unlike rpm-based distributions, Debian stores configuration helpers in /etc/default/, uses update-rc.d for older init scripts, and provides dpkg-reconfigure for interactive package configuration. This tutorial stays on the systemd path throughout. Prerequisites Ensure Debian 13 Trixie […]

A LEMP stack ā Linux, Nginx, MySQL (or MariaDB), and PHP ā is the standard modern web server stack for hosting PHP applications such as WordPress, Laravel, Drupal, and Magento. Compared to the traditional LAMP stack, Nginx handles concurrent requests more efficiently under high load due to its event-driven non-blocking architecture, making it the preferred […]
OpenLiteSpeed (OLS) is the open-source version of LiteSpeed Web Server ā one of the highest-performance HTTP servers available, purpose-built for serving PHP applications. OpenLiteSpeed uses an event-driven architecture similar to Nginx but includes a built-in PHP engine (LSAPI) that processes PHP requests 3ā5x faster than PHP-FPM behind Nginx, eliminating the socket overhead of the FastCGI […]
HAProxy (High Availability Proxy) is a battle-hardened open-source load balancer and proxy for TCP and HTTP workloads. Where Nginx load balancing is sufficient for simple round-robin HTTP distribution, HAProxy provides a richer feature set: advanced health checks with multiple failure thresholds, ACL-based routing, Layer 4 TCP load balancing for non-HTTP protocols (MySQL, Redis, SMTP), detailed […]

Varnish Cache is a high-performance HTTP reverse proxy designed specifically for caching. Unlike Nginx FastCGI cache which caches PHP output files on disk, Varnish stores cached objects entirely in RAM and can serve tens of thousands of requests per second from memory. Varnish operates in front of your web server: it listens on port 80 […]
Nginx FastCGI caching stores the output of PHP-FPM (or any FastCGI backend) responses as files on disk and serves them directly without hitting PHP for subsequent requests. For a WordPress site or PHP application serving the same page to many users, this can reduce PHP execution from 200ms to under 1ms and cut server load […]
