Install cPanel on fresh installation of DigitalOcean CentOS 6 64-Bit
Make sure your hostname have been set properly. Also set Reverse DNS for your IP. Trust me, this will saves you lots of trouble later on.
yum install wget
This will also install htop, iotop, iftop, nethogs and vnstat utilities
wget https://raw.githubusercontent.com/MdNor/cpanel-install-digitalocean/master/install.sh
sh install.sh
There is no way to uninstall cPanel. You have to reinstall operating system to remove it completely.
