Network Installation Linux (5) – KickStart

KickStart configuration is actually instruction to guide kernel to complete the process of the installation. Normally, we will put ks.cfg to somewhere located on NFS server. The exact path is indicated by PXE default configuration,  /tftpboot/linux-install/pxelinux.cfg/defaul, or special configuration you came up with. The whole process of network installation will be:

  1. The client asks IP address from DHCP server.
  2. The DHCP server distribute one IP to the client, at the same time, indicate PXE parameters to the client, especially pxelinux.0.
  3. The client get pxelinux.0 via TFTP.
  4. After user interact with boot.msg, the client will get vmlinuz and initrd.img followed the instruction of pxelinux.cfg/default.
  5. After kernel and driver installation, the client will follow the instruction of ks.cfg to complete the whole process.

The following is my ks.cfg, just for your reference.
