How to configure static IP address on CentOS 

By default CentOS minimal install does not come with pre-configure network. In this small tutorial i will explain how to set static ip address on CentOS 6.5 minimal.
First, need to edit the set up for the ethernet. Let’s start with editing this file:

EDIT Device:
# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
HWADDR=DC:41:A9:52:4E:6D
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
NM_CONTROLLED=yes
PEERDNS=yes
IPADDR=192.168.1.10
NETMASK=255.255.255.0
Now, configure default getaway:

EDIT Network:
# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=centos6
GATEWAY=192.168.1.1
Configure DNS Server

EDIT DNS:
# vi /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

Now restart the network interface:
# /etc/init.d/networking restart
Check eth0:

check configuration:
# ifconfig eth0
eth0 Link encap:Ethernet HWaddr DC:41:A9:52:4E:6D
inet addr:192.168.1.10 Bcast:192.168.0.255 Mask:255.255.255.0
