Re: Fc3 : installation via pxe boot and network



Vis-a-vis Dirk's note of 01/06/2005 05:23 AM:

i`m trying to setup an install server to boot and install systems via network.


Currently I`m using the initrd from base/pxeboot.

Now: the kernel boots fine, the ramdisk is loaded and /sbin/loader starts.

However after loading the network driver it then hangs forever with:
'trying to mount CD device hda'.

Well, of course there is no cdrom media present....

Question: how can i tell the /sbin/loader to start a network install ?

Works fine for me with precisely that initrd. I think that the kickstart piece of the puzzle is what you are missing.


I do an interactive network install by placing the following ks.cfg in /tftpboot/linux-install/FC3/ on my tftp server, too.

#######################################################################
#use NFS installation media
nfs --server 172.24.4.16 --dir /usr/local/Heidelberg
#######################################################################

where /usr/local/Heidelberg/Fedora/{base,RPMS} on my install server contains the install tree and is NFS exported to the network segment (only) where the installees reside.

I also have a much funkier, sort-of-working, localized kickstart config within /usr/local/Heidelberg/Fedora/ that aims to give me a hands-free install of a heavily customized install for the cluster nodes of my web-app backend. I can't claim to be 100% certain of how/why kickstart works in this situation though. I just experiment with each new RH/FC release until I hit a working combination.

FWIW, I did _not_ use the system-config-netboot generated dhcpd.conf, as I my dhcp server lives on a *BSD box, and the generated dhcpd.conf simply didn't work, while one based on the info from the SYSLINUX site: http://syslinux.zytor.com/pxe.php#special has worked for me for some time now. If FC3 now uses a sufficiently modern version of dhcp, the comments there should apply equally.

The bottom line is that it's still neccessary to do a fair amount of Googling & tweaking to use the system-config-netboot tool for installs, though it did make setting up the tftpboot tree _much_ less painful than the system I've used w/ earlier RH's & FC's.

PS It goes without saying (I hope) that you want all your dhcp/tftp/install servers securely isolated from the open Internet; there be monsters.
