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... ;-)
