Step 2: System Requirements for cPanel & WHM 11.30 Installation

note Note: Troubleshooting a Recent Installation — Read this document if you encounter problems installing cPanel & WHM.

Choosing a server

In choosing a server, consider these factors:

  • How many sites you plan to host. For example, if your server will host many websites, each with its own set of email addresses and databases, the server will require more processing power, disk space, and RAM.
  • What kind of web hosting you plan to do. While cPanel and WHM will run on the minimum requirements below, the server will need more processing power, disk space, and RAM if you plan to host videos, music, or high-volume applications like forums.

We offer support for new installations on the operating systems and architectures mentioned below. (Please also read our Important facts to understand before installing document.)
