This procedure describes how to install Oracle Linux 6.7 or 7.2 OS from a PXE network environment. This procedure assumes that you are booting the installation media from one of the following sources:
Oracle Linux 6.7 or 7.2 ISO DVD image
KickStart is an automated installation tool. It enables a system administrator to create a single image containing the settings for some or all installation and configuration parameters that are normally provided during a typical Oracle Linux installation. Typically, a KickStart image is placed on a single network server and read by multiple systems for installation.
Ensure that the following requirements are met prior to performing the Oracle Linux PXE installation:
If you are using a KickStart image to perform the installation, you must:
Create a KickStart file.
Create the boot media with the KickStart file or make the KickStart file available on the network.
To use PXE to boot the installation media over the network, you must:
Configure the network (NFS, FTP, HTTP) server to export the installation tree.
Configure the files on the TFTP server necessary for PXE booting.
Configure the server's MAC network port address to boot from the PXE configuration.
Configure the Dynamic Host Configuration Protocol (DHCP).
