This is a quick heads-up to all who want to set-up a network install platform for ubuntu server 14.04 using a PXE environment with a local package-repository (an http/ftp server with copied contents from the iso image). You will need the knowledge to set up a PXE boot server and configure your DHCP server to point to it. This post has no attention of beeing a complete how-to. Though it does have some vital information on how to set things straight on 14.04. In the pxelinux.cfg/default file you will need a segment similar to the one below: label <X> kernel boo/linux append vga=788 initrd=boot/initrd.gz -- quiet locale=en_US console-setup/layoutcode=sl keymap=sl debian-installer/keymap=sl auto url=http://<your_local_server>/preseed.seed Brief description of the parameters used:
In the preseed.seed file there are many options - you can find many samples on the Internet. The crucial line is the one shown in red. There's been a change to how the installation process works in 12.10 - the setup now copies initial system files from an image instead of installing packages. Here's the example that I use: d-i clock-setup/utc boolean true d-i time/zone string Europe/Ljubljana d-i console-setup/ask_detect boolean false d-i console-setup/layoutcode string sl d-i debian-installer/language string English d-i debian-installer/country string SI d-i debian-installer/locale string en_US.UTF-8 d-i keyboard-configuration/layout select Slovenian d-i keyboard-configuration/variant select Slovenian d-i keyboard-configuration/layoutcode string sl d-i keyboard-configuration/xkb-keymap select sl d-i mirror/country string manual d-i mirror/http/hostname string netboot.abakus.si d-i mirror/http/directory string /iso/ubuntus1404_64 d-i mirror/http/proxy string d-i apt-setup/restricted boolean true d-i apt-setup/universe boolean true d-i apt-setup/backports boolean true d-i apt-setup/services-select multiselect security d-i apt-setup/security_host string netboot.abakus.si d-i apt-setup/security_path string /iso/ubuntus1404_64/ d-i live-installer/net-image string http://<your_local_server>/iso/install/filesystem.squashfs #d-i debian-installer/allow_unauthenticated boolean true d-i preseed/late_command string wget http://<your_local_server>/boot/sources.list -O /target/etc/apt/sources.list The last line helps me set the correct sources.list file to get updates from the Internet. I'ts based on the slovenian mirror site. The reason behind this is the fact that I do not sync the updates mirror to my local server. I therefore get no access to updates unless I use the ones on the Internet. Install process will set apt sources to what you provide within preceed.seed file. So you have to somehow override this at the end of the install process. |
