You have to change the IP address entry in /etc/sysconfig/network-scripts/ifcfg-eth0
save and run: service network restart

Another way is with DHCP reservations. What is acting as your DHCP server?

You would also need to change it in /etc/hosts, and /etc/sysconfig/network would need a hostname change if that too is changing (in addition to /etc/sysconfig/network-scripts/ifcfg-eth0)

However, if you're not comfortable using Unix text editors, just run the command "setup", and highlight the entry for "Network Configuration", and tab down to "Run Tool", and then go into "Device Configuration".

Once you "Save & Exit", the changes should take place right away but if not, run "service network restart"

/etc/sysconfig/network-scripts/ifcfg-eth0
You have to make changes in above file, according to the device ifcfg-eth0 , ifcfg-eth1 ...
