1. Install and configure kickstart

To use the kickstrt installation platform, the complete architecture included is: Kickstart + DHCP+ NFS+TFTP+PXE, as can be seen from the architecture

Services that need to be installed roughly, such as dbcp, tftp, nfs, kickstart/pxe, etc.

Hang in the mirror

Mount / dev/cdrom / mnt

Df-h

1) installation of DHCP and Tftp

Yum install-y dhcp* tftp* syslinux

First configure the tftp service:

Vi / etc/xinetd.d/tftp

Disable = no

Just change disable=yes to disbale=no.

2) TFTP + PXE configuration

To install the system remotely, you first need to specify the relevant PXE kernel modules and related parameters in the TFTpboot directory

The configuration steps are as follows:

# if the system is 5.x, the default tftpboot directory has been automatically created to the / root directory

# if the system is 6.x, the default tftpboot directory is under / var/lib/, so linux 6.x needs to do soft link / root directory.

Check to see if there is a / tftpboot directory under / root, if there is no need to make a soft link

Ln-s / var/lib/tftpboot/ /

Cd / tftpboot/

Find /-name pxelinux.0

Cp / usr/share/syslinux/pxelinux.0. /

Cp / mnt/images/pxeboot/ {initrd.img,vmlinuz}. /

Copy everything to the kernel to the / tftpboot directory

Mkdir-p / tftpboot/pxelinux.cfg

Cd / tftpboot/pxelinux.cfg

Cp / mnt/isolinux/isolinux.cfg default

Chmod 777 / tftpboot/pxelinux.cfg/default

Vi / tftpboot/pxelinux.cfg/default

Add as follows:
