Automatically Installing Linux from Bootable CD? 85

Posted by Cliff from the insert-wait-and-go dept.
phorm asks: "While there are newer many distributions of linux that come bootable from CD, I've found that some are a bit difficult to customize and wonder how hard it would be to create my own. Currently we are looking at replacing some of our Windows desktops at work with Linux test-machines - and it would be nice to make the installation process as simple as possible. How hard would it be to create a bootable CD that would automagically install Linux onto the first detected hard-drive? How would you go about 'imaging' an existing machine to use as the base? I suppose that in many cases a tar-gzip of the entire OS would work, provided you could partition the drive correctly, recreate some important handles as in /proc, and run lilo/grub to install a boot loader. Does anyone here have experience with this? I know morphix/knoppix make nice bootable distros but what I really want is a basic Linux bootCD which installs a preconfigured version of the OS of my choice."

    Symantec/Norton Ghost works very well for mirroring drives.

    However, you may have issues when it comes to differing hardare in different machines, and all your boxes will have the same hostname and IP address.
    • I forgot to mention that some versions of Ghost allow you to create a bootable recovery CD of your system at a given state.

      Read the license agreement, you may need to purchase the correct Ghost license for what you aim to do; the off-the-shelf variety typically allows you to only use it on ONE computer system.

      On imaged systems, it's a bad idea for them not to access the network on first boot.... that means legwork after the image process. I would recommend configuring a DHCP client (with DHCP assigned hostname.)

      For me, this is all I need, as each machine can be assigned statically via the DHCP server.

      Still, IMO Kickstart is a much better methodology. Still better is PXE controlled kickstart mini-distros.... (Ala Ghost/Image Blaster Image partitions.) But I have yet to see someone do this.

    Install a system, configure it the way you want it. Don't install too much stuff, because it needs to fit on a CD.

    Once done, boot into single user mode.

    tar everything up to *another* disk (mounted here under /mnt) --

    cd /
    tar --one-file-system --sparse -zcvvvf /mnt/disk.tar.gz /

    If that file doesn't fit on a CD with at least 10 MB to spare, remove some stuff and try again. export GZIP=9 might help a bit too.

    Get a bootable linux floppy disk image. It doesn't really matter which one, but it does need to have a real filesystem on it (not just a kernel.) Your typical rescue disk will probably work well.

    Make a script to install. It'll be something like this --

    #!/bin/sh -e
    # zero the partition table
    dd if=/dev/zero of=/dev/hda bs=1024 count=10
    sync
    sleep 3
    sync
    # create a 1024mb / partition
    printf "n\np\n1\n+1024m\nw\n" | fdisk /dev/hda
    # create the filesystem
    mke2fs -j /dev/hda1
    # mount it
    mkdir /m /n
    mount /dev/scd0 /cd
    mount /dev/hda /m
    # dump your tar.gz file to the new fs
    cd /m
    tar --totals --preserve --sparse -zxvf /cd/disk.tar.gz
    cd /
    # (re)install the bootloader
    echo "/sbin/grub-install /dev/hda" | chroot /m /bin/sh
    # clean up
    umount /m
    umount /cd
    echo "Ok. Time to reboot!"
    and then this script will replace /sbin/init on your boot floppy. Of course, if your floppy starts something other than /sbin/init, you'll need to replace that.

    Then you'll burn a cd that contains that floppy image as the el Torito boot image, and has that file.tar.gz in the root of the file system.

    This is really rough, and will only work properly with rather specific hardware, but it may get you started. Making a proper distribution is a lot more work than this -- I only spent a few minutes typing this out.

    I have not tested any of this. In particular, the command to do the fdisking probably has issues -- for example, most boot floppies don't have printf by default (you'll need to add it, or a script to just print all the fdisk commands), and I probably got the order of some stuff in the printf statement wrong (it's a string of commands for fdisk.) And of course it'll happily trash whatever is on your disk with no warning. (Installing lilo rather than grub can be done with a similar procedure if needed.)

    But if you're looking for a really quick and dirty way to install lots of identical machines, this may get you started. This is NOT a procedure for anybody who doesn't really understand what all this stuff does and the possible problems -- I just provided it as a first stab at a possible solution under some limited conditions. Note that the general idea can apply to other OSs as well -- I even remember once making a setup that installed OS/2 (off a network share) just like this -- long before Ghost was a gleam in Norton's (or whomever's) eye.

    In any event, I'd suggest seeing what Knoppix has to offer -- if, like another poster suggested, they have a script to just install to a disk, that would probably be far better than this hack.

    • Already, one typo --

      mount /dev/hda /m

      That would need to mount /dev/hda1 /m, of course. There's probably more typos.

      No, I don't really expect anybody to actually do this -- there's already much better stuff out there. But several years ago, before all those smart people solved the problem elegantly for you, this was one way that people would solve problems like this -- with a nasty `one off'.

    I've done something like this for work. Created a custom bootable Linux CD (SuSE 8.2-based), with all the necessary drivers for the hardware it'd run on.

    Then, I have an image server elsewhere on the network, full of dd images of various installs. So, when I build a new machine, I simply boot from the CD, and then pipe dd through ssh ("ssh remotehost 'dd if=foo.dd' |dd of=/dev/sda"), and within an hour (they're 18GB images), the new system is built.

    I can use the same process in reverse for imaging an existing system (or simply use the ssh-piped dd on a live system), to create the stored images.

    I spent so much time rewriting bits of systemimager that I got frustrated. Finally, I ran into hardware systemimager wouldn't support out-of-the-box (devices that only had drivers in 2.4, and SI's 2.2-based), and figured since I was going to have to build a new bootable ROMfs anyway, I may as well make a bootable CD and ditch SystemImager altogether.

    I've built a RedHat kickstart CD that loads the kickstart file via HTTP of a web server. You can write a pre-install script to massage the disks (using either python or shell, probably anything you want, but python and shell are the only to utilities I know are there, in shell you are limited to mostly busy box utilities).

    You can use the redhat-config-kickstart to help you build a default install package set (and to build the kickstart file).

    Then you can run a post install script (also specified in the kickstart script). Generally, I always make my pre/post scripts wget the script I really want them to run. This gives me a bit more flexibility. (Actually I've never written a pre-install script, only posts).

    In the post install scripts, I've used wget to download the set of scripts/config files I wanted to replace (I recommend using a tarfile that you unpack from the filesystem, use diff to apply patches to all of the config files, or use sed to edit the config files).

    From there, it's relatively simple matter of deciding what you want changed and how you want it to work. I generally make sure to install AutoRPM, and the autorpm config files that point to my local package repository. Thus anything I can make into an RPM, I can get deployed onto remote machines in mass. I create one extra AutoRPM package pool for each class of machine, so I can put custom packages by machine type onto each machine.

    Either use PXE boot, or boot from CD. The CD image to do a kickstart style install is on the first RedHat CD. Look for the isolinux directory and create your own ISO (if you edit the files to put ks=http://kickstart.server.com/kickstart/file, then it's completely unattended). Or you can use the prebuilt images in /images, but then you have to fiddle with the command line a bit from CD. I've never done a PXE boot for installation of a machine (used it for building X-terminals, but not for this).

  • You mentioned Debian, so how about:

    1. Spend 15 minutes learning how to remaster Knoppix.
    2. Grab one of the Knoppix installer scripts.
    3. Write a post install script if you want to do more.
    4. Combine #1 and #2, add #3 to taste.
    5. Make lots of copies of the resultant CD.
    6. Run around putting it in drives and rebooting.

    Alternately, put enough of a thing on bootable media to run netcat and a small copy script, and place an image on a central machine, dd it on to the drive, and then do post-install stuff.

  • Make your own debian package that contains as dependancies everything you want installed, then do a minimal install from a netinstall cd or a cd that has the bootfloppies stuff on it and then apt-get install your custom package.
  • Does anyone know of a live CD based on Debian that is oriented towards scientists and mathematicians? For example something that has Octave, Yacas, Maxima, gnuplot, R, LaTeX, Emacs with calc, etc?

    I am considering doing this myself from a morphix lite-gui CD but I don't know enough about how to do it yet. The Morphix docs were not exactly straightforward either.

    I think making morphix auto install by wiping the first hard drive would be easy though (per the original question)

  • It sounds like you want to do something almost identical to what we've done at my work. We build out servers on a regular basis, and need to be able to get a full OS installed as quickly as possible. We have the total install time, from the time we turn the machine on with blank hard drives, to when it's finished rebooting with a working operating system, down to 5 minutes. I'm happy with our time, so we aren't pushing to get it any faster.

    Here's what we do.

    I use Slackware, but this will apply to any O
