How to Install cPanel & WHM on AlmaLinux 9 or Ubuntu 24.04 LTS (2026 Guide)

#linux #sysadmin #devops #tutorial

Hey DEV community! 👋

If you are provisioning a bare-metal dedicated server for web hosting in 2026, you already know that CentOS is officially out of the picture. Getting cPanel & WHM running smoothly on modern OS options like AlmaLinux 9 or Ubuntu 24.04 LTS requires an updated set of pre-flight checks.

Relying on outdated tutorials will often result in conflicting package managers, broken dependencies, and failed installations. Since cPanel cannot be cleanly uninstalled without a complete OS wipe, you have to get it right on the first try.

We just published an in-depth, verified tutorial over at FitServers that cuts through the noise. No fluff—just the exact terminal commands and WHM GUI steps you need to get production-ready.

🛠️ What You Will Learn

Our comprehensive guide covers the entire deployment lifecycle:

  # Example: Starting a persistent session and running the installer
