✅ Server Requirements for cPanel Installation
Before installation, make sure you meet these requirements:
- AlmaLinux / Rocky Linux / CloudLinux OS
- 1.6GHz CPU (2+ cores recommended)
- 2GB RAM (4GB recommended)
- 40GB disk minimum

Avoid pre-installed panels like CyberPanel or aaPanel — cPanel needs a clean server.
🚀 Installing cPanel/WHM
Run these commands on a fresh server:
yum update -y cd /home curl -o latest -L https://securedownloads.cpanel.net/latest sh latest
Installation takes 20-60 minutes. After completion, access WHM:
https://your-server-ip:2087
🔧 Common Installation Errors & Fixes
❌ Hostname Invalid Error
Fix:
hostnamectl set-hostname server.yourdomain.com

Upgrade RAM or add swap:
fallocate -l 2G /swapfile chmod 600 /swapfile mkswap /swapfile swapon /swapfile

Set nameservers inside WHM:
ns1.yourdomain.com ns2.yourdomain.com
Register glue records at your domain provider. If you’re testing DNS, free-domain platforms like freedomain.co.in are useful for beginners learning DNS mapping.
