After you have installed CentOS 6.2 linux server, the network configuration will be like this.
DEVICE="eth0" HWADDR="xx:xx:xx:xx:xx:xx" NM_CONTROLLED="yes" ONBOOT="no"
The system will no get the ip automatically and the network interface will not auto start even after the server rebooted. Follow this steps to set static ip and set it auto start once rebooted in CentOS 6.2 :
1. Configure eth0:
[root@centos6 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0" HWADDR="00:0C:29:67:51:B1" NM_CONTROLLED="yes" ONBOOT="yes" IPADDR=192.168.1.44 BOOTPRO=static NETMASK=255.255.255.0
2. Configure Default gateway:
[root@centos6 ~]# vi /etc/sysconfig/network
NETWORKING=yes HOSTNAME=centos6.2 GATEWAY=192.168.1.1
3. Restart Network interface:
[root@centos6 ~]# /etc/init.d/network restart
or
[root@centos6 ~]# Service network restart
4. Configure DNS server:
[root@centos6 ~]# vi /etc/resolv.conf
nameserver 8.8.8.8 nameserver 192.168.1.1

Exellent!!! Thanks alot )
Thank you for the useful guide. Much appreciated! However, if I may make a suggestion. Usually I use nano, but it seems it is not built in to CentOS6.X so I was not familiar with Vim and assumed CTRL+X would work. May I suggest a quick mention of using ESC then typing :X and hit enter?
