How to Install cPanel and WHM in CentOS 

Installation Requirements

A clean fresh minimal installation of CentOS server.

1. Minimum of 1 GB RAM (but 2 GB recommended).
2. At least 20GB of free disk space (but 40 GB recommended).
3. A valid cPanel license.
4. Standard hostname (FQDN or Fully Qualified Domain Name)
5. Perl

Ensure that your server has a standard hostname (FQDN or Fully Qualified Domain Name), otherwise set it as follows (in this example, cpanel is the hostname and example.com is the domain name):

    # hostnamectl set-hostname cPanel.example.com

cPanel is written in Perl, ensure that you have Perl installed on your server, other wise run the command below to install it on your system.

    # yum install perl

You do not have to run any commands to install it, need to install curl. It will run auto installer script. 

    # yum install curl

Then download the latest installer script to home directory.

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

 Now, run the auto-installer script.

Note that if you have logged in to the server using SSH, we strongly recommend running the cPanel auto installer script in screen mode, because it takes 40-60 mins to complete the installation depending on your server resources and Internet connection speeds.

    # sh latest

Sample Output

Verifying archive integrity... All good.
