Flask is a lightweight Python web framework well-suited for building APIs and web applications on RHEL 8. Gunicorn acts as the production-grade WSGI server that runs your Flask app, while Nginx sits in front as a reverse proxy handling incoming traffic. This guide walks through deploying a Flask application on RHEL 8 using a Python […]
Django is one of the most popular Python web frameworks, and deploying it in production requires more than the built-in development server. The recommended production stack on RHEL 8 pairs Django with Gunicorn as the WSGI application server and Nginx as a reverse proxy that handles static files, TLS termination, and connection management. This tutorial […]
Redis is an in-memory data structure store used as a database, cache, and message broker, capable of delivering sub-millisecond response times for millions of operations per second. On RHEL 8, Redis is available through the AppStream module system, giving you a straightforward installation path without third-party repositories. This guide covers installing Redis 6 via AppStream […]
Introduction Debian 12 Bookworm is built around the ethos of stability and free software. Setting up set up nginx as a reverse proxy on debian 12 on Bookworm leverages the same proven Debian packaging system that powers millions of servers worldwide, while benefiting from the latest upstream releases included in the Bookworm freeze. Follow each […]
WebSockets provide a persistent, full-duplex communication channel over a single TCP connection, making them essential for real-time applications such as chat systems, live dashboards, and collaborative tools. Nginx can act as a reverse proxy that transparently upgrades incoming HTTP connections to the WebSocket protocol and forwards them to a backend application server. This tutorial walks […]
A LAMP stack — Linux, Apache, MariaDB, and PHP — is one of the most widely deployed web server configurations in enterprise environments. RHEL 8 ships with the tools needed to install and configure each component using dnf and its module system. This tutorial walks you through installing and securing a fully functional LAMP stack […]
A LEMP stack — Linux, Nginx, MySQL (or MariaDB), and PHP — is one of the most common foundations for hosting WordPress, Laravel, and other PHP applications. On RHEL 8, each component is available from the default AppStream repository using module streams, giving you fine-grained control over which PHP version you install without relying on […]
HAProxy is a battle-tested open-source load balancer and proxy server that can distribute HTTP and raw TCP traffic across multiple backend servers with sub-millisecond overhead. On RHEL 8 it is available directly from the AppStream repository and integrates cleanly with firewalld and SELinux. This guide walks through installing HAProxy, writing a configuration that handles both […]
Varnish Cache is a high-performance HTTP accelerator designed to sit in front of web servers and serve cached responses at near-wire speed, offloading PHP and database work from your backend. On RHEL 8, Varnish is packaged in the default AppStream repository, making installation straightforward. This guide shows how to install Varnish, write a VCL configuration […]
Nginx FastCGI caching dramatically reduces PHP processing load by storing rendered responses on disk and serving them directly to subsequent visitors. On RHEL 8, combining Nginx with a PHP-FPM backend and a well-configured cache can cut backend response times by 80–95% for cacheable pages. This tutorial walks through configuring the fastcgi_cache_path directive, defining cache keys, […]
