Install CentOS 6.x using Net-Install method

Purpose: The purpose of this document is to outline the basic step to installing CentOS 6.x using the Net-Install method. It is not meant to be comprehensive but rather enough information to complete the basic tasks, some previous Linux knowledge is recommended.

Step 1.) Downloaded Centos netinstall file and burned to CD and verified.

Step 2.) Rebooted blank system with newly created CD in it answered a few basic questions and told it to use DHCP and it began the install.

Step 3.) Pointed to URL (note 32 or 64 bit system):
Http://mirror.centos.org/centos/6/os/i386

Step 4.) Acquire OS updates for the system (from a system command prompt once install complete):
yum update

Note (additional commands):
To update a specific package:
yum update packagename (e.g. yum update httpd)

List updates with:
yum list updates

Listing whats installed:
yum list installed or yum list installed httpd, ect. Or
rpm -qa | less (works better)

To remove a package:
yum remove httpd

Step 5.) To install an X-windows (I preferred KDE to GNOME):
yum groupinstall "X Window System"
yum groupinstall “KDE Desktop”

If you prefer GNOME then:
yum groupinstall "GNOME Desktop Environment"

Note: Only install a single desktop environment (either KDE or GNOME) otherwise additional re-configurations will be required.

Step 6.) To make changes to your network configurations (edit file):
/etc/sysconfig/network-scripts/ifcfg-eth0

Other network related file (where hostname and gateway can be defined):
/etc/sysconfig/network

with syntax:
NETWORKING=yes
HOSTNAME=your.hostname.com
GATEWAY=xxx.xxx.xxx.xxx
