Changing Linux IP address when you have GUI mode installation is easy. But, when you do not have GUI access, it becomes hard to change IP address.
On a Linux minimal install, you can assign new IP address by editing /etc/sysconfig/network-scripts/ifcfg-eth3 file
As root user ============ vi /etc/sysconfig/network-scripts/ifcfg-eth3 --> replace old ip and gateway --> save and close
Restart the network
service network restart
