The cPanel/WHM installation requires a clean Operating System for installation, or else problems may occur.
The installation of cPanel/WHM is simple but does take 60-90 minutes to complete. Once you have purchased a full license through our Sales department or a VPS license through our control panel, you can do the following to install:

iptables -F
/etc/init.d/iptables save
cd /home
wget http://layer1.cpanel.net/latest
chmod +x latest
screen
./latest

The above commands do the following:

• Clear all IP Tables (firewall) rules and save the changes
• Download the cPanel install script
• CHMOD the script so it can be ran
• Go into a “screen” so that you can perform your normal work while installing
• Run the install script

We have you run the screen command because this install can take 60-90 minutes. To close out of it, without disrupting it, simply press CTRL+A+D. You can revisit the install at any time by typing screen -r.
