Important Facts
Please keep these facts in mind when you install cPanel & WHM software:
- 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.
- You should install a minimal version of the operating system. All services that cPanel requires will automatically be installed during the cPanel & WHM software installation process. Installing services prior to the installation of cPanel & WHM software 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.
Installation Instructions
To install cPanel & WHM software 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.
