Hardware details:

Processor: It is advised to use a contemporary multi-core processor with a clock speed of at least 2 GHz. The anticipated workload and the quantity of websites hosted will determine the number of cores.

Operating Systems Supported:

cPanel is mainly meant to operate on Red Hat Enterprise Linux (RHEL), CloudLinux, and CentOS. These operating systems give cPanel’s features a reliable and secure base.
cPanel supports different Linux distributions, such Ubuntu and Debian, however their installation and configuration may call for extra processes.

Dependencies on Software:
