how to change hostname in linux
Very often you might want to change the hostname in your linux server. The hostnames are usually written like…
vps.domain.com
server.domain.com
box.domain.com
web.domain.com
and it is a very good idea to follow this hostname format.
To change hostname all you have to do is modify 2 files
1. Open /etc/hosts and change the name of the host
127.0.0.1 vps.domain.com vps localhost localhost.localdomain
2. Open /etc/sysconfig/network and do the change
HOSTNAME="vps.domain.com"
Once this is done, check whether the hostname has been changed using hostname command after restart.
Thats all!

WHM has a tool for this. Much easier. I couldn’t figure it out after taking those steps… Host name still shows my vps#.host.com
