Install Centos6.4 in unattended PXE

Install Centos6.4 in unattended PXE

To use pex, kickstart, (ftp, HTTP, nfs), tftp, DHCP, and Centos6.4 are required.

1) ks. cfg file creation

1 [root@wwwshare] #yuminstall-ysystem-config-kickstart

Kickstart creates ks. cfg Based on/root/anaconda-ks.cfg (Disk allocation, time zone, language, rpm package and other parameters configured during system installation)

2) Build an ftp server and prepare the RPM Software Package

3) Prepare the Centos6.4 boot file. This is the key part (TFTP)

Install and start tftp
