If you're attempting to do this on a headless server you can edit the following files and reboot to get your eth0 networking device to come up enabled and acquire an IP address from a DHCP server. Change these 2 options in the file, /etc/sysconfig/network-scripts/ifcfg-eth0:

ONBOOT="yes"
NM_CONTROLLED="no"
