Easisest way of changing Linux (CentOS, Fedora, RedHat) Hostname

February 19, 2011

Use the echo command to replace the contents of /proc/sys/kernel/hostname with your new host name. 

# echo hostname.com > /proc/sys/kernel/hostname

Then restart the network interfaces: 

# /etc/init.d/network restart Shutting down interface venet0:  [  OK  ] Shutting down loopback interface:  [  OK  ] Bringing up loopback interface:  [  OK  ] Bringing up interface venet0: RTNETLINK answers: File exists RTNETLINK answers: File exists [  OK  ]

Now you can use the hostname command to verify that it has changed.

 Be it known that it will not touch or changed any thing in /etc/hosts use it at your own Descretion =)
