Pxe+kickstart Cobbler Unattended Installation

Environment Preparation:

A single server

Pxe+kickstart Automatic Installation principle:

PXE (Preboot Execute environment, pre-boot execution Environment) is the latest technology developed by Intel Corporation, working in the network mode of client/server, enabling workstations to download images from remote servers over the network, This supports booting the operating system over the network, and during the boot process, the terminal requires the server to assign an IP address, then TFTP (trivial File Transfer Protocol) or MTFTP (Multicast trivial file transfer Protocol) protocol to download a boot package to native memory execution, completed by this boot package terminal (customer? Basic software settings to boot the terminal operating system that is pre-installed in the server. PXE can boot a variety of operating systems, such as: Windows95/98/2000/windows2003/windows2008/winxp/win7/win8,linux.
