This article describes how to create an appliance based on UCS 3. It is recommended to use the latest UCS 3 version. The appliance mode can only configured on a Domaincontroller Master. Later in the configuration wizard it is possible to change the server role.

= Installation =
 
 
 
While selecting the system role in UCS 3 Domaincontroller Master installation, F3 must be pressed. This will disable the join scripts. After the installation the system should be upgraded to the latest version, for example by running the following command as user root:
 
<source lang= bash>
 
univention-upgrade
 
</source>
 
 
 
After that the package univention-system-setup-boot should be installed. There are three ways to configure the UCS system: local, remote or automatic.
 
 
 
== Local configuration ==
 
 
 
The local configuration will start a firefox session at the next boot. For this setup the access to the graphical console of the system is essential. In this session all requirements for the configuration will be asked and the system will be configured. To activate this mode univention-system-setup-boot can be installed by the following command:
 
<source lang= bash>
 
univention-install univention-system-setup-boot xinit firefox-en
 
</source>
 
 
 
== Remote configuration ==
 
 
 
The remote configuration is necessary, when the access to the local console is not given. The configuration takes place in a remote web browser session. Therefore, the network address of the booting system must be known. Usually the X window system will be installed when univention-system-setup-boot is installed, this can be prevented by adding ''--no-install-recommends'' to the command. Additionally, the start of firefox should be prevented by disabling the UCR variable ''system/setup/boot/start'':
 
<source lang= bash>
 
univention-install univention-system-setup-boot --no-install-recommends
 
ucr set system/setup/boot/start="false"
 
</source>
 
 
 
== Automatic configuration ==
 
 
 
An automatic configuration is possible by creating a profile file (''/var/cache/univention-system-setup/profile''). Here is an easy example for creating such a file and running setup-join.sh:
 
 
 
<source lang= bash>
 
cat > /var/cache/univention-system-setup/profile <<__HERE__
 
hostname="ucs"
 
domainname="testdom.local"

= Preparing Amazon EC2 Images =
 
 
 
The following section describes, how the images at Amazon EC2 are prepared. How to use the prepared image is described in the [[Amazon EC2 Quickstart| Amazon EC2 Quickstart Guide]].
 
 
 
== Installation ==
 
 
 
* The easiest way is to install UCS into KVM with the raw image format for the harddisks, one for root and one for swap. The root partion should be configured without LVM. AMD64 is recommended as the architecture of choice. Amazon EC2 images must be configured with remote or automatic mode, because the local console can not be accessed.
 
* The disk size should be set to 3 GB
 
* The following values should be set during the installation:
 
** System language: ''English'' (default)
 
** Time zone: ''America/New_York'' (default)
 
** Keyboard layout: ''US american'' (default)''
 
** System role: ''Master domain controller'' + Disable join scripts by pressing F3
 
** Fully qualified domain name: ''ucsmaster.ucs.local''
 
** LDAP base: ''dc=ucs,dc=local'' (autofilled)
 
** Windows domain name: ''UCS'' (autofilled)
 
** Root password: univention
 
** Partitioning: ''Auto-Partitioning''
 
** Network: ''Dynamic (DHCP)''
 
** Software: ''Deselect all''
 
** Overview: Select ''Update system after installation'' (default)
 
 
 
== Configuration ==
 
 
 
Amazon EC2 uses Xen, therefore the following changes are required after the installation, upgrade and configuration:
 
<source lang= bash>
 
# change from sda to xvda and re-configure grub
 
ucr set grub/root=/dev/xvda1
 
sed -i 's|/dev/sda1|/dev/xvda1|;s|/dev/sdb1|/dev/xvda3|' /etc/fstab
 
append="$(ucr get grub/append)"
 
ucr set grub/append="$(echo "$append" | sed -e 's|/dev/sda|/dev/xvda|g;s|splash|nosplash|')"
 
ucr set grub/grub1root="(hd0)"
 
univention-grub-generate-menu-lst
 
 
# generate all UMC languages
 
ucr set locale/default="en_US.UTF-8:UTF-8" locale="en_US.UTF-8:UTF-8 de_DE.UTF-8:UTF-8"; locale-gen
 
 
 
# Remove persistent net rule
 
rm -f /etc/udev/rules.d/70-persistent-net.rules
 
 
# overwrite old update/available flag
 
ucr set update/available=false
 
 
 
# install univention-system-setup-boot
 
univention-install univention-system-setup-boot
 
ucr set system/setup/boot/start=false
 
 
 
# SSH with authentication key will be used in EC2, so remove the root password
 
usermod -p \* root
 
 
 
# Activate EC2 mode
 
ucr set server/amazon=true
 
 
 
# Activate DHCP
 
ucr set interfaces/eth0/type=dhcp dhclient/options/timeout=12
 
ucr unset gateway
 
 
# Set a default nameserver and remove all local configured nameserver
 
ucr set nameserver1=208.67.222.222 dns/forwarder1=208.67.222.222
 
ucr unset nameserver2 nameserver3
 
ucr unset dns/forwarder2 dns/forwarder3
 
 
 
# Remove persistent net rule
 
rm /etc/udev/rules.d/70-persistent-net.rules
 
</source>

== Configuration ==
 
 
 
The following changes are required after the installation and upgrade:
 
<source lang= bash>
 
# allow X11 login as normal user
 
ucr set 'auth/gdm/group/Domain Users=yes'
 
 
# Disable xorg autodetection and set resolution to 1024x768
 
ucr set xorg/autodetect=no \
 
    xorg/device/driver=vmware \
 
    xorg/resolution=1024x768
 
 
# Disable kernel mode set

# Ensure dbus will be restated after the configuration
 
cat >/usr/lib/univention-system-setup/appliance-hooks.d/dbus <<__EOF__
 
#!/bin/sh
 
test -x /etc/init.d/dbus && /etc/init.d/dbus restart
 
__EOF__
 
chmod +x /usr/lib/univention-system-setup/appliance-hooks.d/dbus
 
 
 
# Ensure s4connector will be restated after the configuration
 
cat >/usr/lib/univention-system-setup/appliance-hooks.d/s4connector <<__EOF__
 
#!/bin/sh
 
test -x /etc/init.d/univention-s4-connector &&

</source>
 
 
 
* The ISO image should be removed from the VMware hardware settings.
 
* After that, the permissions of the files should be set to 755 and the vmware log files can be removed, for example:
 
<source lang= bash>
 
chmod -R 755 <directory of virtual machine>
 
rm <directory of virtual machine>/vmware*.log>
 
</source>
 
 
 
*  Finally a ZIP archive should be created
 
<source lang= bash>
 
zip -r ucs-<version>-demo-image.zip <directory of virtual machine>
 
md5sum ucs-<version>-demo-image.zip > ucs-<version>-demo-image.zip.md5
 
</source>
 
 
 
== Later customization ==
 
 
 
A VMware image of UCS that has been created by following the above outlined steps can be further customized later. For example, 3rd party software may be added to the image.
 
 
 
The VMware image starts UCS into the system wizard. The system configuration follows the same steps as outlined in the article [[Operation and Configuration of the UCS system in VMware]]. The following steps abort the system setup wizard for customized configuration and re-activates the system setup wizard for the next system reboot:
 
 
 
* Start the VMware image until the system setup wizard shows up.
 
* Press ''Ctrl + q'' to quit the system setup wizard and Mozilla Firefox.
 
* Press ''F8'' two times to enter a console.
 
* Switch to the first console, for example by pressing Ctrl-Alt-F1. If you use  VMware under Linux you have to press Ctrl+Alt+Space, release the space, keep holding down Ctrl+Alt and then press the F1 key.
 
* Login with ''root'' and the password provided during installation. If the [http://www.univention.de/en/download/preinstalled-vmware-images/ UCS VMware image from the Univention Website] is used, the password is ''univention''.
 
* Work through the intended customizations.
 
* ''Optional step'': The pages displayed in the system setup wizard can be customized using the following UCR variables: <tt>system/setup/boot/pages/whiteliste</tt> and <tt>system/setup/boot/pages/blacklist</tt>. Options for the pages are <tt>HelpPage, SystemRolePage, LanguagePage, BasisPage, NetworkPage, CertificatePage, SoftwarePage</tt>. If the <tt>BasisPage</tt> is put on the blacklist, the administrator password needs to be set on the system (described in this [http://forum.univention.de/viewtopic.php?f=48&t=1938#p6812 forum post] (German)):
 
<source lang="bash">
 
mkdir -p /var/lib/univention-ldap
 
echo -n "secret root password" > /var/lib/univention-ldap/root.secret
 
chmod 600 /var/lib/univention-ldap/root.secret
 
</source>
 
* When finished, the system setup wizard has to be activated for the next boot.
 
<source lang=bash>
 
ucr set system/setup/boot/start="true"
 
</source>
