Hi,
I have some very basic questions on this relationship. I have read
through the Cobbler man page and some of the other available
information. I plan to setup a RHEL5 Cobbler server to do a PXE based
network installation of several servers. Here are my questions:
1) What network protocol is used to do the actual network OS
installation? This detail seems to be missing from the docs but from
what I have read it appears to be http…I am wanting to know how the
PXE client accesses the files on the cobbler server.
First there's DHCP
PXE uses TFTP
Kickstarts are served over http:// if using Cobbler templating, but also
can be ftp:// or nfs://
The install by default, if using Cobbler import is http://, which most
people use, but can also be ftp:// or nfs://
2) I am going to Import a loop mounted DVD iso for my RHEL5 distro (so
I do not have to expand the install tree). I plan to use Kickstart
Configurator to generate unique kickstarts…I may use ks templating
later. In the ks file, what do I put for “Installation Method” (CD,
NFS, HTTP, Hard-drive)? If I choose HTTP, what path do I use for the
“HTTP Directory”? It is supposed to be the location of the “Server”
directory from the distro but since I used iso’s I do not have one.
Will Cobbler explode the iso and create an Install Tree in
/var/www/cobbler? If so I can specify that dir…
The easiest way to start out is to just import the mounted DVD
cobbler import --name=foo --mirror=/mnt/dvdlocation
That will create cobbler distros and profiles, as well as assign a base
kickstart (which lives in /etc/cobbler)
If you want to use templating you can, or you can use an existing
kickstart you have available in your web space
cobbler profile edit --name=foo
--kickstart=http://bootserver.example.org/foo.ks
Sorry, I know I could do some experimenting but do not have the setup
for this yet and am in planning stage. Understanding some of these
basics will help me out greatly.
No problem...
You may also be interested in #cobbler on irc.freenode.net which is also
good for quick questions like this.
Thanks!
