When installing cPanel to your new server, a check is performed to see if an FQDN (fully-qualified domain name) is set up as the hostname. If this hostname is not valid, the installation will fail at that point.
Your hostname (mycpanel.hostname) is invalid, and must be
set to a fully qualified domain name before installing cPanel.
A fully qualified domain name must contain two dots, and consists of two parts: the hostname and the domain name.
You can update your hostname by running `hostname your-hostname.example.com`, then re-running the installer.
********************* ERROR *********************
You can update the hostname through a couple of different methods through the command line, but the following directions are to use 'hostnamectl,' which is available for the majority of the OSes cPanel Supports.
You can verify your current hostname by running the hostname command:
Step 1: Use set-hostname to Change the Hostname
Type the following command:
hostnamectl set-hostname new-hostname
Be sure to use your own hostname choice instead of
*Make sure the new hostname the requirements for an FQDN.
Step 2: Use hostnamectl to Confirm the Change
When the command is successful, 'hostnamectl set-hostname does not produce any output.
Therefore, use 'hostnamectl' to check the result.
