cPanel is very particular about making sure that the server you are using has a (Fully Qualified Domain Name). On this basis, one should provide a valid hostname. However, skipping this step will certainly give you the following error.
· (ERROR): Your hostname () is not set properly. Please
· (ERROR): change your hostname to a fully qualified domain name,
· 463 (ERROR): and re-run this installer.
Although, you can fix this error with a very simple solution. If you already have a FQDN (Fully Qualified Domain Name ), you can type it in with the command:
· hostname your FQDN
Or else, if you want to continue with the cPanel installation but do still lack a hostname, what you can do is to insert a temporary one. Once cPanel is installed and configured, you will be able to change it to the right one at one of the very first setup pages.
· hostname host.example.com
Hope that helps you solve this issue.
