703136 - Set up kickstart on admin1a.infra.scl1.mozilla.com

Status: RESOLVED FIXED

(Infrastructure & Operations :: RelOps: General, task)

Description

[Dustin J. Mitchell [:dustin] (he/him)]

This machine should be given enough equipment to kickstart new RHEL nodes in vlan6, similar to what we do in mtv1 or sjc1.

Comment 1

[Matthew Larrain[:MaRu]]

I have started reading up on how to push this out but any internal recommendations would be nice. so far I have run;
yum install tftp-server
yum install syslinux
yum install httpd

Comment 2

[Dustin J. Mitchell [:dustin] (he/him)]

This should probably be done with puppet - there appears to be a kickstart module there.  I don't know what it does and doesn't install or set up, though.

Comment 3

[Matthew Larrain[:MaRu]]

that module isn't done yet so it will have to be done by hand.

Comment 4

[Matthew Larrain[:MaRu]]

With justdave's help I was able to get this machine almost all finished. It doesn't have a big enough hdd to take all the images so Dustin will select just the ones needed. Also DHCP needs to be updated to be able to hand out IP's for kickstarting.

So I blew away everything under /var/www/html/kickstart and /var/lib/tftpboot.

I copied in the important stuff from /var/lib/tftpboot on natasha:
 pxelinux.cfg/default (edited to use admin1a's IP address, have the right options)
 pxelinux.0
 msgs/ (edited heavily)
 RHEL-6.0-x86_64/

started xinetd for tftp service.

Applied this patch to dhcp:

and fired up a DL120G7's iLO to see how it works so far (more will be needed in /var/http/www/kickstart, but I want to get this part right first)

Comment 6

[Dustin J. Mitchell [:dustin] (he/him)]

To get the rest working, I needed to start httpd (and set it to start on boot), and copy the appropriate files there from mvadm01.  I've set up CentOS 6.0 so far.

Matt, can you set up and test RHEL-6.0?

RHEL6 successfully added.
