- cPanel does not support 32-bit Virtual Environments that run on a 64-bit host kernel.

Please keep these facts in mind when you install cPanel & WHM:
- We strongly recommend a system that exceeds the minimum requirements. This is especially true if you plan to host a large number of domains and accounts.
- We strongly recommend using CentOS or Red Hat® Enterprise Linux® if you are not an experienced FreeBSD administrator.
- You should install a minimal version of the operating system. All services that cPanel requires will automatically be installed during the cPanel & WHM installation process. Installing services prior to the installation of cPanel & WHM will cause compatibility problems.
- Because cPanel is designed for commercial hosting, we only license publicly visible, static IP addresses. We do not license dynamic, sticky, or internal IPs.
- cPanel does not support NAT.
To install cPanel & WHM on CentOS:
- Download a free CentOS DVD ISO. To use this ISO, you must burn the image to a DVD. Then, insert the DVD into the server and turn it on.
- Upon its first reboot, the ISO will install cPanel and WHM in the background.
- For more details, read our documentation on Installing cPanel and WHM. If you have questions, please contact our sales team.
