Running multiple PHP-FPM versions (e.g., PHP 8.2 and PHP 8.4) on an Ubuntu server with at least 16 CPUs and 60GB RAM should ideally provide smooth performance. However, if your server is experiencing high load, it’s crucial to identify the root cause and optimize your setup. In this guide, we’ll explore common issues that lead to high server load when running multiple PHP-FPM versions and provide practical solutions to resolve them. Why Is Your Server Under High Load? When running multiple PHP-FPM versions, several factors can contribute to high CPU or memory usage: Let’s dive into each issue and explore…

tmpfs is a temporary in-memory file system used in Linux to store files directly in RAM instead of on disk. It is designed for fast read/write operations, making it an ideal choice for storing runtime data, temporary files, and volatile information that does not need to persist after reboot. In a Linux server environment, understanding how tmpfs works is essential for optimizing performance, reducing I/O load, and improving overall system efficiency. How tmpfs Works When you create a tmpfs mount, Linux allocates storage in RAM (and swap, if available). Unlike traditional disk-based file systems, tmpfs dynamically grows and shrinks based…

Learn how to harden SSH and Access Control Hardening on Ubuntu and openSUSE Linux servers using proven commands, configuration examples, and outputs. Strengthen system security and compliance with best practices for SSH hardening. Key advantages of Access Control Hardening: Comprehensive Access Control Hardening Steps 1. Disable Root Login Root login via SSH is one of the most targeted attack vectors. Disabling root access prevents attackers from brute-forcing the default “root” account. Commands (Ubuntu & openSUSE): Verify: Expected Output: Explanation: This ensures only non-root users can connect. Admins must log in with their personal accounts and use sudo for privileged operations.…
