Sommaire

Description

Suite a la configuration du serveur PXE pour réalisé des installations par le réseau, voici la documentation pour que cette installation soit réalisé automatiquement. Ceci vous permettra d'installé un grand nombre de machine sans être obligé de répondre a toutes les questions de l'installation. Ceci permettra aussi d'Avoir un setup uniforme de toutes vos machines.

Pour réalisé ce setup nous utiliserons le système preseed fournie par debian, il est aussi possible d'utilisé le système kickstart développé par Redhat malheureusement plusieurs option ne sont pas disponible pour Ubuntu. Un example la configuration du RAID software. Le fichier preseed sera récupéré sur un serveur web, lors d'une installation réseaux il n'est pas possible de définir un path vers le fichier :(.

Prérequis: - Avoir un serveur PXE - Avoir un serveur WEB.

pour le setup du serveur PXE avec la configuration de l'installation de Ubuntu par le réseaux consulté cette page Installation serveur PXE pour installation


  • Petit problème  :
    • Le setup pour Intrepid pose encore 3 questions a corrigé prochainement.
    • j'utilise kickstart pour le setup du clavier je n'ai pas réussie avec preseed :(.

Réalisation du fichier Preseed

Telle que mentionné plus haut le fichier preseed sera récupéré sur un serveur web, je pars du principe qu'un serveur web est mis en place sur la machine.

### Clock and time zone setup
# Controls whether or not the hardware clock is set to UTC.
#clock-setup     clock-setup/ntp boolean true
d-i clock-setup/utc boolean true

# You may set this to any valid setting for $TZ; see the contents of
# /usr/share/zoneinfo/ for valid values.
d-i time/zone string Canada/Eastern

# Controls whether to use NTP to set the clock during the install
d-i clock-setup/ntp boolean true
# NTP server to use. The default is almost always fine here.
d-i clock-setup/ntp-server ntp.ubuntu.com

### Partitioning
# If the system has free space you can choose to only partition that space.
# Alternatives: custom, some_device, some_device_crypto, some_device_lvm.
#d-i partman-auto/init_automatically_partition select biggest_free

# Alternatively, you can specify a disk to partition. The device name must
# be given in traditional non-devfs format.
# For example, to use the first SCSI/SATA hard disk:
#
#d-i partman-auto/disk string /dev/sda

# Note: If you want to use whatever disk is available, no matter
# what its device name, comment the line above out. This will only work if
# the system only has one disk.
# In addition, you'll need to specify the method to use.
# The presently available methods are: "regular", "lvm" and "crypto"
d-i partman-auto/method string regular

# If one of the disks that are going to be automatically partitioned
# contains an old LVM configuration, the user will normally receive a
# warning. This can be preseeded away...
d-i partman-auto/purge_lvm_from_device boolean true
# And the same goes for the confirmation to write the lvm partitions.
d-i partman-lvm/confirm boolean true

# You can choose from any of the predefined partitioning recipes.
# atomic: All files in one partition (recommended for new users)
# home: Separate /home partition
# multi: Separate /home, /usr, /var, and /tmp partitions
# small_disk (alpha architecture only):
#   Small-disk (< 1GB) partitioning scheme
#
d-i partman-auto/choose_recipe select atomic

#d-i partman-auto/choose_recipe select home
#d-i partman-auto/choose_recipe select multi
#d-i partman-auto/choose_recipe select small_disk

# Or provide a recipe of your own...
# The recipe format is documented in the file devel/partman-auto-recipe.txt.
# If you have a way to get a recipe file into the d-i environment, you can
# just point at it.
#d-i partman-auto/expert_recipe_file string /hd-media/recipe

# If not, you can put an entire recipe into the preconfiguration file in one
# (logical) line. This example creates a small /boot partition, suitable
# swap, and uses the rest of the space for the root partition:
#d-i partman-auto/expert_recipe string                         \
#      boot-root ::                                            \

#                      use_filesystem{ } filesystem{ ext3 }    \
#                      mountpoint{ / }                         \
#              .                                               \

#              .

# This makes partman automatically partition without confirmation, provided
# that you told it what to do using one of the methods above.
d-i partman/confirm_write_new_label boolean true
d-i partman/choose_partition select finish
d-i partman/confirm boolean true

### Base system installation
# Select the initramfs generator used to generate the initrd for 2.6 kernels.
#d-i base-installer/kernel/linux/initramfs-generators string yaird

# The kernel image (meta) package to be installed; "none" can be used if no
# kernel is to be installed.
#d-i base-installer/kernel/image linux-generic

### Account setup
# Skip creation of a root account (normal user account will be able to
# use sudo). The default is false; preseed this to true if you want to set
# a root password.
#d-i passwd/root-login boolean false
# Alternatively, to skip creation of a normal user account.
#d-i passwd/make-user boolean false

# Root password, either in clear text
#d-i passwd/root-password password r00tme
#d-i passwd/root-password-again password r00tme
# or encrypted using an MD5 hash.
#d-i passwd/root-password-crypted password [MD5 hash]

# To create a normal user account.
#d-i passwd/user-fullname string Ubuntu User
#d-i passwd/username string ubuntu
# Normal user's password, either in clear text
#d-i passwd/user-password password insecure
#d-i passwd/user-password-again password insecure
# or encrypted using an MD5 hash.
#d-i passwd/user-password-crypted password [MD5 hash]
# Create the first user with the specified UID instead of the default.
#d-i passwd/user-uid string 1010
#d-i passwd/userfullname string dsheffner
#d-i passwd/user-password password password
#d-i passwd/user-password-again password password
d-i passwd/user-fullname string Ubuntu Server Administrator
d-i passwd/username string ubuntuadmin
d-i passwd/user-password-crypted password $1$oYK1Adewqd3PYXp3IipBR54vrgvrevev0

# The user account will be added to some standard initial groups. To
# override that, use this.
#d-i passwd/user-default-groups string audio cdrom video

### Apt setup
# You can choose to install restricted and universe software, or to install
# software from the backports repository.
d-i apt-setup/restricted boolean true
d-i apt-setup/universe boolean true
#d-i apt-setup/backports boolean true
# Uncomment this if you don't want to use a network mirror.
d-i apt-setup/use_mirror boolean false
# Select which update services to use; define the mirrors to be used.
# Values shown below are the normal defaults.
d-i apt-setup/services-select multiselect security
d-i apt-setup/security_host string security.ubuntu.com
d-i apt-setup/security_path string /ubuntu

# Additional repositories, local[0-9] available
#d-i apt-setup/local0/repository string \
#       http://local.server/ubuntu &releasename; main
#d-i apt-setup/local0/comment string local server
# Enable deb-src lines
#d-i apt-setup/local0/source boolean true
# URL to the public key of the local repository; you must provide a key or
# apt will complain about the unauthenticated repository and so the
# sources.list line will be left commented out
#d-i apt-setup/local0/key string http://local.server/key

# By default the installer requires that repositories be authenticated
# using a known gpg key. This setting can be used to disable that
# authentication. Warning: Insecure, not recommended.
#d-i debian-installer/allow_unauthenticated string true

### Package selection
#@tasksel tasksel/first multiselect standard, ubuntu-desktop
tasksel tasksel/first multiselect standard, ubuntu-desktop
#tasksel tasksel/first multiselect standard, ubuntu-server
#tasksel tasksel/first multiselect standard, lamp-server
#tasksel tasksel/first multiselect standard, kubuntu-desktop

# Individual additional packages to install
d-i pkgsel/include string openssh-server build-essential

# Language pack selection
#d-i pkgsel/language-packs multiselect ca, fr

# Some versions of the installer can report back on what software you have
# installed, and what software you use. The default is not to report back,
# but sending reports helps the project determine what software is most
# popular and include it on CDs.
#popularity-contest popularity-contest/participate boolean false

### Boot loader installation
# Grub is the default boot loader (for x86). If you want lilo installed
# instead, uncomment this:
#d-i grub-installer/skip boolean true
# To also skip installing lilo, and install no bootloader, uncomment this
# too:
#d-i lilo-installer/skip boolean true

# This is fairly safe to set, it makes grub install automatically to the MBR
# if no other operating system is detected on the machine.
d-i grub-installer/only_debian boolean true

# This one makes grub-installer install to the MBR if it also finds some other
# OS, which is less safe as it might not be able to boot that other OS.
d-i grub-installer/with_other_os boolean true

# Alternatively, if you want to install to a location other than the mbr,
# uncomment and edit these lines:
#d-i grub-installer/only_debian boolean false
#d-i grub-installer/with_other_os boolean false
#d-i grub-installer/bootdev  string (hd0,0)
# To install grub to multiple disks:
#d-i grub-installer/bootdev  string (hd0,0) (hd1,0) (hd2,0)

# On systems where unauthorized users have access at boot time, you may want
# to set a GRUB password, either in clear text
#d-i grub-installer/password password insecure
#d-i grub-installer/password-again password insecure
# or encrypted using an MD5 hash.
#d-i grub-installer/password-crypted password [MD5 hash]

### Finishing up the installation
# Avoid that last message about the install being complete.
d-i finish-install/reboot_in_progress note

# This will prevent the installer from ejecting the CD during the reboot,
# which is useful in some situations.
#d-i cdrom-detect/eject boolean false

# This is how to make the installer shutdown when finished, but not
# reboot into the installed system.
#d-i debian-installer/exit/halt boolean true

### X configuration
# X can detect the right driver for some cards, but if you're preseeding,
# you override whatever it chooses. Still, vesa will work most places.
#xserver-xorg xserver-xorg/config/device/driver select vesa

# A caveat with mouse autodetection is that if it fails, X will retry it
# over and over. So if it's preseeded to be done, there is a possibility of
# an infinite loop if the mouse is not autodetected.
#xserver-xorg xserver-xorg/autodetect_mouse boolean true

# Monitor autodetection is recommended.
#xserver-xorg xserver-xorg/autodetect_monitor boolean true
# Uncomment if you have an LCD display.
#xserver-xorg xserver-xorg/config/monitor/lcd boolean true
# X has three configuration paths for the monitor. Here's how to preseed
# the "medium" path, which is always available. The "simple" path may not
# be available, and the "advanced" path asks too many questions.
#xserver-xorg xserver-xorg/config/monitor/selection-method \
#       select medium
#xserver-xorg xserver-xorg/config/monitor/mode-list \
#       select 1024x768 @ 60 Hz

### Preseeding other packages
# Depending on what software you choose to install, or if things go wrong
# during the installation process, it's possible that other questions may
# be asked. You can preseed those too, of course. To get a list of every
# possible question that could be asked during an install, do an
# installation, and then run these commands:
#   debconf-get-selections --installer > file
#   debconf-get-selections >> file


#### Advanced options
### Running custom commands during the installation
# d-i preseeding is inherently not secure. Nothing in the installer checks
# for attempts at buffer overflows or other exploits of the values of a
# preconfiguration file like this one. Only use preconfiguration files from
# trusted locations! To drive that home, and because it's generally useful,
# here's a way to run any shell command you'd like inside the installer,
# automatically.

# This first command is run as early as possible, just after
# preseeding is read.
#d-i preseed/early_command string anna-install some-udeb

# This command is run just before the install finishes, but when there is
# still a usable /target directory. You can chroot to /target and use it
# directly, or use the apt-install and in-target commands to easily install
# packages and run commands in the target system.
#d-i preseed/late_command string apt-install zsh; in-target chsh -s /bin/zsh

Explication du fichier preseed pour le desktop

Je vais rapidement couvrir les points important cependant je vous invite a consulter le site de debian pour une documentation complète:

  • Nous sommes situé au Canada donc le mirroir que j'utilise ainsi que le timezone définie:
d-i mirror/country string CA
d-i     mirror/http/hostname    string  ca.archive.ubuntu.com
d-i     mirror/http/mirror      select  ca.archive.ubuntu.com
d-i     mirror/http/directory   string  /ubuntu/
d-i time/zone string Canada/Eastern

Actuellement j'utilise les mirroirs ubuntu sur internet pour les installations cependant si vous avez beaucoup de serveur ou workstation a installé je vous conseille de réalisé un mirroir ubuntu local.

  • Pour le partitionnement , je laisse le setup par default de ubuntu

# By default the installer requires that repositories be authenticated
# using a known gpg key. This setting can be used to disable that

### Package selection

# Language pack selection
#d-i pkgsel/language-packs multiselect ca, fr

# Some versions of the installer can report back on what software you have
# installed, and what software you use. The default is not to report back,
# but sending reports helps the project determine what software is most
# popular and include it on CDs.
#popularity-contest popularity-contest/participate boolean false

### Boot loader installation
# Grub is the default boot loader (for x86). If you want lilo installed
# instead, uncomment this:
#d-i grub-installer/skip boolean true
# To also skip installing lilo, and install no bootloader, uncomment this
# too:
#d-i lilo-installer/skip boolean true

# This is fairly safe to set, it makes grub install automatically to the MBR
# if no other operating system is detected on the machine.
d-i grub-installer/only_debian boolean true

# This one makes grub-installer install to the MBR if it also finds some other
# OS, which is less safe as it might not be able to boot that other OS.
d-i grub-installer/with_other_os boolean true

# Alternatively, if you want to install to a location other than the mbr,
# uncomment and edit these lines:
#d-i grub-installer/only_debian boolean false
#d-i grub-installer/with_other_os boolean false
#d-i grub-installer/bootdev  string (hd0,0)
# To install grub to multiple disks:
#d-i grub-installer/bootdev  string (hd0,0) (hd1,0) (hd2,0)

# On systems where unauthorized users have access at boot time, you may want
# to set a GRUB password, either in clear text
#d-i grub-installer/password password insecure
#d-i grub-installer/password-again password insecure
# or encrypted using an MD5 hash.
#d-i grub-installer/password-crypted password [MD5 hash]

### Finishing up the installation
# Avoid that last message about the install being complete.
d-i finish-install/reboot_in_progress note

# This will prevent the installer from ejecting the CD during the reboot,
# which is useful in some situations.
#d-i cdrom-detect/eject boolean false

# This is how to make the installer shutdown when finished, but not
# reboot into the installed system.
#d-i debian-installer/exit/halt boolean true

### X configuration
# X can detect the right driver for some cards, but if you're preseeding,
# you override whatever it chooses. Still, vesa will work most places.
#xserver-xorg xserver-xorg/config/device/driver select vesa

# A caveat with mouse autodetection is that if it fails, X will retry it
# over and over. So if it's preseeded to be done, there is a possibility of
# an infinite loop if the mouse is not autodetected.
#xserver-xorg xserver-xorg/autodetect_mouse boolean true

# Monitor autodetection is recommended.
#xserver-xorg xserver-xorg/autodetect_monitor boolean true
# Uncomment if you have an LCD display.
#xserver-xorg xserver-xorg/config/monitor/lcd boolean true
# X has three configuration paths for the monitor. Here's how to preseed
# the "medium" path, which is always available. The "simple" path may not
# be available, and the "advanced" path asks too many questions.
#xserver-xorg xserver-xorg/config/monitor/selection-method \
#       select medium
#xserver-xorg xserver-xorg/config/monitor/mode-list \
#       select 1024x768 @ 60 Hz

### Preseeding other packages
# Depending on what software you choose to install, or if things go wrong
# during the installation process, it's possible that other questions may
# be asked. You can preseed those too, of course. To get a list of every
# possible question that could be asked during an install, do an
# installation, and then run these commands:
#   debconf-get-selections --installer > file
#   debconf-get-selections >> file


#### Advanced options
### Running custom commands during the installation
# d-i preseeding is inherently not secure. Nothing in the installer checks
# for attempts at buffer overflows or other exploits of the values of a
# preconfiguration file like this one. Only use preconfiguration files from
# trusted locations! To drive that home, and because it's generally useful,
# here's a way to run any shell command you'd like inside the installer,
# automatically.

# This first command is run as early as possible, just after
# preseeding is read.
#d-i preseed/early_command string anna-install some-udeb

# This command is run just before the install finishes, but when there is
# still a usable /target directory. You can chroot to /target and use it
# directly, or use the apt-install and in-target commands to easily install
# packages and run commands in the target system.
#d-i preseed/late_command string apt-install zsh; in-target chsh -s /bin/zsh

Bien entendu il pourra être intéraissant d'avoir plusieurs fichier preseed selon la tache du serveur.

Réalisation du fichier Kickstart

Ici J'ai utilisé le fichier kickstart car j'avais un gros PROBLEME, lors des installations mon clavier était mal détecté et malheureusement je n'ai pas encore trouvé la solution a mon problème. Ici c'est une patch que j'espere corriger sous peu :).

  • Création du fichier kickstart:
vi /var/www/ks-ubuntu.txt

FICHIER:

# System language

# System keyboard
