Install cPanel manually
This guide shows how to install cPanel & WHM manually on a fresh AlmaLinux server using the official installer. It also explains how to fix incorrect disk quota reporting in cPanel.
Recommended method: The easiest way to get started is using our OS templates. Select cPanel directly in your PowerPanel during the installation.
Manual cPanel Installation
Install cPanel on a freshly installed, minimal OS (e.g., AlmaLinux). Do not run this on a server with existing data or services.
Fixing Disk Quota Issues
Follow these steps as root to repair the quota system if disk usage is displayed incorrectly in cPanel.
Step 1: Run the cPanel quota script
cPanel provides its own script that checks the quota configuration and repairs it – for ext4 as well as for XFS, the default file system on AlmaLinux:
Step 2: Reboot
On XFS, quotas can only be activated when the file system is mounted. If the script adjusted the mount or boot options, reboot the server:
Step 3: Check the result
After the reboot, check that quotas are active and disk usage is reported:
Important: Run the script as root and do not edit /etc/fstab manually on XFS – incorrect mount options can prevent the server from booting. In that case, use the rescue mode.
