This article explains how to change the hostname of a Linux machine.

Content / Solution:

The default hostname is deployed based on the IP address of the machine. 

Changing the hostname requires the modification of a single file, /etc/sysconfig/network and an examination of the system-wide hosts file, /etc/hosts is also recommended.  After changing the hostname, a reboot of the system will be required to commit the change.
