Prerequisites and Initial Setup This guide assumes a fresh Ubuntu 24.04 LTS installation with root or sudo privileges. We’ll be setting up a robust, isolated multi-tenant environment for PHP applications served by Nginx and managed by PHP-FPM. The core of our isolation strategy will leverage Systemd’s control group (cgroup) capabilities to enforce resource limits per […]
Understanding InnoDB Deadlocks and Lock Wait Timeouts During high-concurrency events like flash sales, enterprise applications leveraging MariaDB 10.11 with the InnoDB storage engine can experience significant performance degradation due to deadlocks and lock wait timeouts. These issues arise when multiple transactions attempt to acquire locks on the same resources (rows, tables) in conflicting orders, leading […]
Understanding Nginx TCP Socket Buffer Tuning for Magento 2 Checkouts High-volume Magento 2 checkouts are a critical performance bottleneck for many e-commerce enterprises. During peak traffic, especially during sales events, the sheer volume of concurrent TCP connections and data transfer can overwhelm default operating system and Nginx configurations. This leads to increased latency, dropped connections, […]

This guide assumes you are running Ubuntu 22.04 LTS (Jammy Jellyfish) with PHP 8.1 and a standard LAMP/LEMP stack. The primary goal is to upgrade to PHP 8.3 […]
Prerequisites and System Preparation This guide assumes a clean Ubuntu 24.04 LTS (Noble Numbat) server instance. Ensure your system is up-to-date. For production environments, it’s highly recommended to use a dedicated server or a VPS with sufficient resources (CPU, RAM) to handle your Laravel application’s expected load. We will be installing PHP 8.3-FPM, which is […]
0. The Root Problem: The Subfolder Hosting Gap The journey didn’t start with a proxy; it started with a limitation. Mintlify is a fantastic documentation platform, but it has a specific constraint: you can only map custom domains to subdomains (e.g., docs.yourdomain.com). Most modern marketing and SEO strategies, however, demand that documentation live in a […]
If you’re running Ollama on your Ubuntu server, you likely know it defaults to 127.0.0.1:11434. While this works for local testing, exposing it securely to external platforms requires a robust reverse proxy. In this guide, we’ll use Apache to bridge that gap and secure your firewall. Step 1: Enable Necessary Apache Modules To act as a […]
If you’re self-hosting a Blynk Server, you might encounter issues where your hardware (like ESP8266 or ESP32) or mobile app cannot connect to the server. This is often caused by the server’s firewall (UFW) blocking the necessary ports. In this guide, we’ll walk through identifying the Blynk ports and how to expose them safely. Step […]
