How to Install cPanel and WHM in CentOS
Installation Requirements
A clean fresh minimal installation of CentOS server.
- Minimum of 1 GB RAM (but 2 GB recommended).
- At least 20GB of free disk space (but 40 GB recommended).
- A valid cPanel license.
- Standard hostname (FQDN or Fully Qualified Domain Name)
- 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.
