Server installation using kickstart on the network

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux (RHEL) 7

Issue

Our kickstart is not present on the installation media, but on the network in central storage.

How to set the initial network configuration on the kernel command line?

Resolution

Get the iso DVD installation image name:

~]# mount -o loop /rhel/RHEL-7.7-20190723.1-Client-x86_64-dvd1.iso /media/
~]# lsblk -nPo MOUNTPOINT,LABEL
...
MOUNTPOINT="/media" LABEL="RHEL-7.7 Client.x86_64"
...

or

~]# blkid
...
/dev/sr0: UUID="XXXX-XX-XX-XX-XX-XX-XX" LABEL="RHEL-7.7 Server.x86_64" TYPE="iso9660" PTTYPE="dos"

Use the following kernel parameters (Network Interface Configuration Formats) for installation, replace spaces with \x20:

boot: linux append initrd=initrd.img ip=xx.xx.xx.xx::xx.xx.xx.yy:255.255.255.0:machine_name:ens192:none inst.stage2=hd:LABEL=RHEL-7.5\x20Server.x86_64 inst.ks=http://xx.xx.xx.zz/ks08.cfg
