A description of how to make Cobbler, PXE, and UEFI behave for Red Hat Enterprise Linux 6 installations

UEFI PXE Installation of RHEL6.4

For some reason, starting a PXE boot installation of RHEL6.4 on UEFI systems is poorly documented. Simultaneously, the process is not terribly verbose when it fails. Here's what I had to do to get this to work.

We going to use Cobbler to take care of a lot of the gruntwork (TFTP, DHCP, etc). It's entirely possible to do it without Cobbler, but even accounting for its warts it will make you more

Convert .crt & .key files into .pem file for HTTParty

Two ways to do it, but only worked for me so I'll put it first and the second for reference:

$ openssl pkcs12 -export -in hostname.crt -inkey hostname.key -out hostname.p12
$ openssl pkcs12 -in hostname.p12 -nodes -out hostname.pem

Other options for this method in comments below:

# Note, the -certfile root.crt appends all CA certs to the export, I've never needed these so it's optional for my personal steps
$ openssl pkcs12 -export -in hostname.crt -inkey hostname.key -certfile root.crt -out hostname.p12

Note, I've always had my hostname.crt as part of my .pem, so I keep my certs but apparently you may not have to, hence the nocerts flag being an extra option in this sample
