Installing cPanel on AlmaLinux 9 (2025)

cPanel & WHM is one of the most widely used control panels in the web hosting industry. Following CentOS, cPanel officially supports RHEL-based systems such as AlmaLinux. The following steps detail how to install cPanel on a clean AlmaLinux 9 system.

System Requirements

• AlmaLinux 9 x86_64 (clean installation recommended)

• SSH access with root privileges

• Minimum 2 GB RAM (4 GB or more recommended)

• At least 20 GB of free disk space

• Static IP address

1. Update the System

dnf update -y

2. Set the Hostname

hostnamectl set-hostname server.domain.com

The hostname must be in Fully Qualified Domain Name (FQDN) format.

3. Install Required Packages

dnf install perl -y

The cPanel installation script is written in Perl, making this package mandatory.

4. Remove NetworkManager and firewalld Services

cPanel recommends avoiding NetworkManager for network configuration.

systemctl stop NetworkManager
systemctl disable NetworkManager
dnf remove NetworkManager firewalld -y

5. Reboot the System (Optional)

reboot

6. Download the cPanel Installation Script

cd /home
curl -o latest -L https://securedownloads.cpanel.net/latest

7. Start the cPanel Installation

sh latest

This process may take approximately 30–40 minutes depending on the server’s internet speed and hardware performance.

8. Access the WHM Panel

Once the installation is complete, WHM can be accessed via:

https://your-server-ip:2087

Login credentials:

Username: root
Password: your server's root password

Additional Notes

• After installation, a 15-day trial license is automatically activated.

• A permanent license can be purchased through cPanel’s official sales channels or authorized partners.

• Upon first login, WHM presents a setup wizard to guide through initial configurations.
