Request
This function changes the server's hostname.
Warning:
- Do not select a hostname that begins with
wwwor a number, or a hostname that ends with a hyphen (-) character. - You must use a fully-qualified domain name (FQDN) that contains two periods (for example,
hostname.example.com). - Do not choose a hostname that a cPanel account on your server will use.
- Do not choose a potential service subdomain (proxy subdomain) as a hostname (for example,
cpanel.example.comorwhm.example.com).
Important:
If you update your hostname, the system blocks user access to cPanel's Calendars and Contacts interface (cPanel >> Home >> Email >> Calendars and Contacts).
The system restores access to this interface after the hostname update finishes. For more information, read our Interface Lock Scripts documentation.
Note:
Whenever you change the server's hostname, you must use one of the following methods:
- Use WHM's Change Hostname interface (WHM >> Home >> Networking Setup >> Change Hostname).
- Call WHM API 1's
sethostnamefunction. - Run the
/usr/local/cpanel/bin/set_hostnameutility as therootuser. These methods ensure that all of the necessary system and service changes occur.

Request
This function determines if your system requires a reboot to apply quotas, software package updates, or kernel updates.
Important:
This function cannot detect whether your system needs a reboot if you use cPanel & WHM inside of a Linux Container (LXC).
