Aim

To enable unattended installation and configuration of Ubuntu on nodes, so that their configuration matches the master machine. This is achieved with PXE boot and configuration with Kickstart.

PXE

Install tftp server 

apt-get install tftpd-hpa

Netinstaller

Download and install pxelinux to tftp root: 

cd /var/lib/tftpboot/
wget http://archive.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64/current/images/netboot/netboot.tar.gz
tar -xvzf netboot.tar.gz

Note: trusty = ubuntu 14.04, precise = ubuntu 12.04

Set the kickstartfile as default, and the timer to 5 sec

Enter the txt.cfg file 

sudo nano /var/lib/tftpboot/ubuntu-installer/amd64/boot-screens/txt.cfg

Rename the "default install" line to "default unattended" so the the unattended kickstart file will be executed by default

Insert the "label unattended" section in the bottom ofthe file 

label unattended
        menu label ^Unattended install
        kernel ubuntu-installer/amd64/linux
        append vga=768 initrd=ubuntu-installer/amd64/initrd.gz ks=http://10.0.0.1/kickstart/ks.cfg

Change the timeout value to 50 in the default file. 

sudo nano /var/lib/tftpboot/pxelinux.cfg/default

Kickstart

Install the http server lighttpd 

sudo apt-get install lighttpd

Create the ks.cfg file 

nano /var/www/kickstart/ks.cfg

The kickstart file

Copy/paste the following text to the ks.cfg file. (Make your own changes like ip addresses and domain name, so it will fit your setup.)

Note: When choosing a password, be sure to make it more than eight symbols, with letters, numbers and special symbols. "unattended" install will stop, waiting for confirmation of a weak password, if this advice is not followed... ;-)
