Centos 6.6 minimal install to Desktop

I am going with Centos 6.6 instead of 7.1 because I have Michael Jhang's book which covers version 6

Burn the minimal install CD

At the root prompt


Enable Networking
Edit /etc/sysconfig/network-scripts/ifcfg-eth0 and change 
onboot=yes
bootproto=dhcp  

#chkconfig network on
#service network restart

# yum -y groupinstall "Internet Browser"

# yum -y groupinstall "General Purpose Desktop"
