Are you looking to add a virtual interface to an existing or additional nic card or are you looking to get your network setup initially?

There are couple of methods for assigning IP address
for newbies you should try
#system-config-network (On GUI)

OR


#system-config-network-tui (ON CLI)

By default it takes the IP from the ISP's DHCPas soon as you are connected to a network. if you want to assign an IP manually:

#system-config-network
firing this from command line will give you a GUI interface.

OR

Code:
vi /etc/sysconfig/network-scripts/ifcfg-eth0
and make below changes:

DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=x.x.x.x                        # mention your IP address here
save and quit
restart the network service.

You missed the gateway

GATEWAY=X.X.X.X
