Operation and Configuration of the UCS system in VMware or VirtualBox
From Univention Wiki
The article describes operation and first steps in the demo system of Univention Corporate Server (UCS) in VMware. A sufficient latest VMware Player (>= 4.0) is recommended.
The VMware image (Download) includes a complete installed and pre-configured UCS system in the system role domain controller master. The system offers more possibilities than the online demo system. It is a complete UCS system with access restrictions to test functionality and application.
Virtualization with UCS Virtual Machine Manager (UVMM) can not be tested with a virtualized UCS system. The installation of UCS on hardware is required for virtualization.
Starting the VMware image
The UCS VMware image can be downloaded as zip archive from the download area. After extracting zip archive, the VMware image can be used in VMware Player (free download at http://www.vmware.com/download/player/).
After the installation of VMware Player, the UCS VMware image can be started on Linux with the following command:
$ vmplayer path to download/VMwareImageName.vmx
Upon start the boot menu appears. The default chosen entry Univention Corporate Server … will be started either with the return key or automatically after 5 seconds. After the first boot, UCS opens the wizard for the base settings using UCS Appliance mode.
The network access in the VMware image is set to "Bridged mode" in order to enable a network configuration for access to the test system from inside the local network. The wizard guides the user through the following steps of the initial configuration UCS as VMware image.
|Language settings for configuration of the available languages on the system. English and German are already chosen in UTF-8 encoding.||thumb|Language settings|
|Basic settings for configuration of fully qualified domain name (FQDN), LDAP base, Windows domain and Root password.LDAP base and Windows domain are automatically suggested according to the FQDN and can be customized. The Root password has to be filled in.||thumb|Basic settings|
|Network settings for configuration of IPv4 and if necessary IPv6 addresses and the gateway. The test system is configured with the fixed IPv4 address 192.168.0.140. The first entry in the list for the nameservers should be the local IP address of the UCS demo system, because UCS comes with an own name services. The network settings can be changed later in the modul Base settings in the UCS management system.||thumb|Network settings|
|Certificate settings for configuration of the SSL certificate. The settings may be left as is.||thumb|Certificate settings|
|Software settings for installation of additional software components. Depending on the test purpose additional software components may be chosen that will be installed after finishing the configuration. The component Mail server has been chosen as additional component in this example.||thumb|Software settings|
|All necessary settings are made after the software settings and can be applied to the test system by clicking on Apply changes.||thumb|Apply changes|
|Finishing the configuration takes a moment. Hostname, LDAP base, Domain and network settings are configured, if necessary additional software will be installed and the system will join the domain.||thumb|Configuration progress|
|After all the system will be restarted.||thumb|Restart|
First steps in the UCS demo system
The system can be accessed with the already present accounts "root" and "Administrator" after the reboot. Both user accounts use the Root password that has been set during the base settings.
A SSH server is installed on the UCS demo system. The user "root" can login via SSH, if the network settings have been customized accordingly. With the SSH login the user has direct access to the system (e.g. univention-config-registry or view log files in /var/log/…).
UCS management system
The UCS management system can be accessed with a web browser through the configured IP address during the initial configuration. The URL is https://<IP address>. For example, if the suggested IP address 192.168.0.140 has been set, the URL would be https://192.168.0.140.
All settings in the scope of the domain can be configured in the domain management of the UCS management, e.g. management of users, groups, computers, configuration of services etc. The user account "Administrator" can be used for administration tasks. In principle, all users in the group "Domain Admins" are allowed to make changes in the domain management.
KDE is installed as desktop on the UCS demo system. It allows users to have a graphical login to the system. The user "root" is not allow to login to the desktop by default. To test the graphical environment without adding a new user, the user "Administrator" may be used.
Add further systems to the UCS environment
Windows client computers
Univention Corporate Server provides functionality known from Microsoft Windows server systeme to Windows client computers. The demo systems includes an Active Directory compatible domain controller that allows the management of users, printers and shares that can be accessed from Microsoft Windows client computers. This requires the Microsoft Windows clients to be member of the domain. If the UCS demo system can be reached over the network from a Microsoft Windows client computer, the Windows client may join the domain just as if it joins a Windows domain.
The following settings are required:
- domain name: The domain name has been set in the Basic settings during initial configuration.
- User that is allowed to join systems to the domain: Administrator
- Password: The password has been set in the basic settings for Root password during initial configuration.
After the Microsoft Windows client computer has joined the domain, an entry for the joined computer is created in the computer management of the domain management.
If additional UCS systems (servers or desktops) should be operated in the environment, they have to be installed seperately. It is not possible to operate the UCS demo system repeatedly in different system roles. Detailed information about the installation can be found in the UCS Quickstart Guide and in the UCS manual.
Univention Corporate Server differs from other Linux distributions among other things by its sophisticated management system. The UCS management system is well-rooted into several areas of the system. That is the reason why UCS includes concepts and mechanisms like domain management or Univention Configuration Registry for the administration of several UCS systems that are not know from other distributions. Univention Corporate Server - Manual for users and administrators is the available documentation for UCS.
