CentOS 7 Kickstart File & How to build an (auto install) ISO

README.md

CentOS 7 Kickstart File - HOWTO Build ISO

There is so much documentation online from RedHat and CentOS about this topic - it's sad that I am writing this. But the real state of documentation on this topic (CentOS 7 + KS + ISO = Bootable DVD) is almost non-existent.

I found this: http://smorgasbork.com/component/content/article/35-linux/151-building-a-custom-centos-7-kickstart-disc-part-1

Which I greatly appreciate and +1, but the documentation is half-baked and there are numerous errors.

Finally... FINALLY! After four days of banging my head, I got this to work. Hopefully someone else will be able to do this in a few hours, instead of blowing their weekend like me. :(

GOAL

  • CentOS 7 Minimal Installation + Kickstart + ISO = DVD or USB for easy installs.

What you need

  • 2 Hours (If you're a Ninja)
  • CentOS 7 VM installed and updated with the version that you want to clone (Minimal install for Minimal ISO, Everything for Everything ISO, etc.)
  • Deep Breaths / Fine Malted Beverage


**BEGIN**
  1. Download your ISO
  2. Install the ISO to a VM with the options you want
  3. Reboot and re-mount the ISO
  4. Make the following directories:
 ~/kickstart_build
    +-- isolinux
    | +-- images
    | +-- ks
    | +-- LiveOS
    | +-- Packages
    +-- utils

ahhh the irony... Funny enough I was able to do this in roughly 3 hours +- (for tweaking etc) with the link you supplied and said that " the documentation is half-baked and there are numerous errors. " the documentation is actually pretty spot-on with the exception of the perl script which I left out of my implementation and it worked 100%, unless the Doc has been updated since you attempted to use it in which case I apologize :)

I'm new to iso. I'm wondering is there a way that:

  1. install a Minimal CentOS 7
  2. install my own rpms and do whatever customization
  3. based on the contents of this server, create a ISO

You advertise yourself as "NINJA", however you look more like someone who didn't have som #### for weeks, because this is clearly not finished. Better to remove it to make you look more "GANGSTER"...!
