Kickstart is awesome for automating the building CentOS/RedHat servers. There are a number of ways that you can do it, such as PXE booting of the network etc, but the way I choose to do it requires a simple boot CD.
1. Download the latest DVD ISO from your favourite mirror.
2. Either burn the ISO to a DVD or soft mount it on a Linux/Unix server.
3. Make a directory that you want to use as your NFS share
4. Share this directory over NFS.
5. Create a directory to hold the contents of the DVD
6. Copy the contents of the DVD in to this directory
1. Make a directory to hold the Kickstart configuration file on the NFS server
3. Make the kickstart file world readable
1. Download the latest DVD ISO of the distro you wish to use. In this case it's CentOS 5.5 x86_64.
2. Either burn the DVD ISO to DVD media or soft mount it on your machine.
3. Make a directory to hold the boot image data
4. Copy the 'images' and 'isolinux' directories from the DVD into the bootimage folder
5. Go into the 'isolinux' directory and edit the isolinux.cfg file with the following contents:
In this example, the server will use network interface eth0, will get it's IP from DHCP and will get it's kickstart config file, kickstart.ks, from the nfs server 192.168.1.1 in the specified directory.
6. Make a bootable ISO image of this directory:
7. Burn the new ISO, ks.iso, to CD using your favourite burning software.
