Before Installing cPanel/WHM, You must ensure that your VPS OS is CentOS.
We recommend CentOS 6 x64 (64 Bit) Base OS.
Once your VPS is ready, login to VPS Shell via putty (or similar tools) and issue these commands as root user :
yum -y install screen nano zip unzip
screen -S cpanel_install
yum -y update
yum -y groupinstall “Base”
It will start cPanel/WHM installation on your VPS. It may take 50-60 minutes to get installed depending upon your VPS configuration.
If your SSH Session disconnects while install cPanel, installation will still be running in background.
to reconnect to see progress of your cPanel Installation, Just reconnct to your VPS via SSH and run this command :
screen -dr cpanel_install
