Script for Automate Ubuntu Installation - SysAdmin - 08-28-2020
The complete solution is:
Remaster a CD, ie, download a non graphical ubuntu installation ISO (server or alternate installation CD), mount it
$ sudo su -
# mkdir -p /mnt/iso
# mount -o loop ubuntu.iso /mnt/iso
Copy the relevant files to a different directory
# mkdir -p /opt/ubuntuiso
# cp -rT /mnt/iso /opt/ubuntuiso
Prevent the language selection menu from appearing
# cd /opt/ubuntuiso
# echo en >isolinux/lang
Use GUI program to add a kickstart file named ks.cfg
# apt-get install system-config-kickstart
# system-config-kickstart # save file to ks.cfg
To add packages for the installation, add a %package section to the ks.cfg kickstart file, append to the end of ks.cfg file something like this.
%packages
@ ubuntu-server
openssh-server
ftp
build-essential
This will install the ubuntu-server "bundle", and will add the openssh-server, ftp and build-essential packages.
Add a preseed file, to suppress other questions
# echo 'd-i partman/confirm_write_new_label boolean true
d-i partman/choose_partition \
select Finish partitioning and write changes to disk
d-i partman/confirm boolean true' > ks.preseed
Set the boot command line to use the kickstart and preseed files
# vi isolinux/txt.cfg
Search for
label install
menu label ^Install Ubuntu Server
kernel /install/vmlinuz
append file=/cdrom/preseed/ubuntu-server.seed vga=788 initrd=/install/initrd.gz quiet --
add ks=cdrom:/ks.cfg and preseed/file=/cdrom/ks.preseed to the append line. You can remove the quiet and vga=788 words. It should look like
append file=/cdrom/preseed/ubuntu-server.seed \
initrd=/install/initrd.gz \
ks=cdrom:/ks.cfg preseed/file=/cdrom/ks.preseed --
Now create a new iso
# mkisofs -D -r -V "ATTENDLESS_UBUNTU" \
-cache-inodes -J -l -b isolinux/isolinux.bin \
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 \
-boot-info-table -o /opt/autoinstall.iso /opt/ubuntuiso
That's it. You'll have a CD that would install an Ubuntu system once you boot from it, without requiring a single keystroke.
