Installing cPanel on VPS
Installing cPanel: this can be done in many ways.Let’s see the most popular one first – via SSH, then other ways.
CentOS with Perl and screen (programming languages).
Via SSH.

1. Make sure Perl is installed:
   yum install -y perl
2. Create a fully qualified domain name:
   hostname server.example.com
3. Create the necessary packages and screen:
   yum install wget screen -y
4. Open a new screen session:
   screen -S cPanel_Installation
5. Download and install the installation script:
   wget -N http://httpupdate.cPanel.net/latest
   sh latest
6. For DNS-only version:
   wget -N http://httpupdate.cPanel.net/latest-dnsonly
   sh latest
7. Useful commands for working with screen:
   Stop: control-a-d #combination disconnects from the screen session
   Continue: screen -r. #combination connects to a previously created screen session

Via the web interface of the hosting provider
If your hosting provider provides the means to install a leased or virtual domain, you can take this chance and install cPanel through your VPS provider’s web interface.
As a general example:

1. Open your VPS provider’s website and log in to your profile;
2. Find the “Server Management” or similar section and select cPanel from the list of available panels.
3. Next, follow the automatic installation instructions.

Through an automatic installation script.
Some hosting providers create special scripts for their customers to run pages. This can be a convenient alternative to automatic installation through the panel.

1. Uploading:
   Log in to your hosting provider’s website and download the cPanel auto-install script.
2. Running it on the server:
   sh install_cpanel.sh

Note: unfortunately, cPanel does not support Ubuntu. You need to use other panels for this system, such as Plesk or Webmin.
