In this CentOS 5.5 tutorial we will be showing you how to change the hostname. The assumption is that you are running as root and have a basic understanding of the software required but if you follow this tutorial you should be able to complete the task successfully.
To find the machine’s fully qualifier domain name (FQDN) see for yourself how the machine identifies itself:
# uname -n
centos01.how2centos.com
# dnsdomainname
how2centos.com
