How to change hostname in Redhat & Oracle Linux

As user “root”

“vi /etc/sysconfig/network”, change HOSTNAME value to the new hostname

“hostname NEW_HOST_NAME” to change it for the current sessions

“vi /etc/hosts”, change the old value to point to the new hostname

“service network restart” to restart the networking service and apply all the new changes
