If you want install cpanel on your VPS server you need order cPanell license and after payments you can run:

wget -N http://httpupdate.cpanel.net/latest

sh latest

Now it starts installing. It will take ~2h to complete installation. It depends on your server’s speed. Make sure you don’t write anything to console while it installs or installation might fail.

So if everything is installed you have to activate your cPanel / WHM license. It goes like that:

/usr/local/cpanel/cpkeyclt

And you are done. If everything went well you can access WHM now. To go to your WHM go to: http://youriphere:2086.

At least 256 MB of RAM (enough to run Yum).

sh ./kloxo-installer.sh –type=master

wget http://download.lxcenter.org/download/kloxo/production/kloxo-installer.sh
sh ./kloxo-installer.sh –type=<master/slave> –db-rootpassword=PASSWORD
