Set fixed ip address to different servers - rodrigo.lima - 2017-05-06 15:07

Hi all,

I`m using ipxe to deploy kickstart files on my infrastructure. But, I would like to improve it.
I have dozens of servers in different datacenters, and these datacenters do not offer a dhcp service, then I need to set a fixed ip for each server. I would like to know if is possible to create only one iso image and only one menu.ipxe in this case.
Currently, I need to create various menu.ipxe for each server with a fixed address.

Thanks,

I feel your pain.

I use a generic menu script for the Menu UI, then I wrote a script to write an ${uuid)-network.ipxe script on the server from a MasterUUID.csv file.

The Output is something like this (this is for booting into the installer with the intention of installing in an NFS Roots environment via Serial TUI):

Code:

#ipxe

echo ${cls}

#GENERATED BY Build_UUID_network_iPXE.sh or Build_UUID_network_iPXE.cmd

#Filename output is ${uuid}-network.ipxe

#87891122-abab-cdcd-efef-1234abcd5678-network.ipxe

set hostname yourserver

set nfs_nic_one 1

set nfs_nic_two 6

set nfs_nic_order 1-2

set nfs_ip 10.100.1.100

set nfs_netmask 255.255.255.128

set nfs_server 10.100.1.10

set def_gateway 10.100.1.1

set def_menu_opt 2_OpenSuSE-nfs-bond

set dist_opt "OpenSuSE"

chain ${17}/NetBoot/iPXE/ipxelinux.cfg/OEM/SuSE/OpenSuSE_menu.ipxe || echo

chain ${17}/NetBoot/iPXE/ipxelinux.cfg/default/default-efi.ipxe || echo

#END

This could also be put into a PHP script which parses a read-only CSV file or queries a MySQL Database.

The OpenSuSE_menu.ipxe puts the variables set in the above script into parameters for booting the installer... e.g.:

Code:

#!ipxe

echo Booting OpenSuse Installer (AutoYast,ttyS0)...

initrd ${17}/Media-Depot/linux/OpenSuSE/x86_64/loader/initrd || echo
