Before you install cPanel & WHM or cPanel DNSONLY, make certain that your system meets all of our minimum requirements for new installations.
We only develop and test cPanel & WHM on file systems that support flock. Some network file systems (for example, NFS) may require additional configuration in order to function properly.
Make certain that you complete the following tasks before you install your operating system or any cPanel product:
Register your fully qualified hostname — This hostname cannot match any of your server's domains (for example, if
example.com is a domain on your server, register
hostname.example.com as your fully qualified hostname).
During the installation process, you must also configure your Ethernet device with a static IP address and fully qualified hostname.
You cannot use an IP address that a DHCP service dynamically assigns to your server.
