The Open-Xchange Server Edition for Univention Corporate Server (OXSE4UCS) includes the groupware Open-Xchange and the integration packages for Univention Corporate Server (UCS).
  
 +
OXSE4UCS is tailored to professional users looking for a tried-and-tested solution for the management of their entire IT infrastructure including groupware or companies which already employ UCS and wish to expand their infrastructure with innovative groupware functions.

More detailed information on UCS can be found on the Univention GmbH website: [http://www.univention.de/dokumentation.html].
−
===Planing a scenario===
 
−
Before the installation you must decide which scenario for the OXSEforUCS-integration will be used. You can find the supported scenarios in the specifications of OXSEforUCS in chapter 7. For simplification the installation only varies between 3 cases

====UCS Master installation====
+
As OXSE4UCS is an expansion pack for the Univention Corporate Server, one or more UCS server(s) must be installed firstly.  
−
A UCS Master is required for every scenario. It is possible to use an existing UCS Master, if so, exactly '''UCS version 2.2-3 must''' be installed.
 
  
−
'''Please Note: For installation, please only this mentioned path with UCS 2.2-3. UCS 2.3 is currently not supported for the OXSE for UCS and there is no possibility to downgrade UCS 2.3 to 2.2-3.'''
+
There are several possible different installation scenarios. In principle, OXSE4UCS can be installed on all UCS domain controller server roles: DC master, DC backup or DC slave. Installation on the server roles member server or base system is not currently possible.
  
−
The UCS ISO images are available at http://apt.univention.de/download/ucs-cds/ucs2.2-0/
+
To start, the UCS systems are installed as usual with UCS 2.3. If several systems are in the UCS domain, a check must be performed that the join procedure has been run on all servers. This is usually done at the end of the installation procedure. Further information on the installation of UCS can be found in the UCS manual: [http://www.univention.de/dokumentation.html].

−
* In the next step you have to partition the medium, that you're going to install to. This is left up to your needs. You're welcome to use the auto partitioner that will create swap-space and apply the LVM onto the partitions.
+
apt-get update
−
After that, press F12 and install the bootloader, again with F12.
 
−
* After that, your are requested to enter the Data for your networking interface. Press F12.
 
−
 
 
−
The nameserver field should contain the nameserver, that handles the previously configured domain. As UCS brings its own nameserver '''bind''', this could also be 127.0.01 or the IP address of the networking interface, configured previously. Please enter the DNS-server of your ISP into the DNS Forwarder field. This will be automatically entered into bind. An optional proxy server can be entered in the HTTP proxy field. F12

2.1  Installation on a DC master
−
Mail/Groupware: Kolab 2 for UCS, Kolab 2 Webservices</p><p>
+
When installing OXSE4UCS on a DC master, only the univention-ox-meta-singleserver package requires installing. This can be performed via the Univention Management Console or on the command line:
−
Systemservices: Thinclient Environment</p><p>
 
−
Graphical UI: all</p>
 
−
* In the following step, you can choose to mirror the univention-repository locally. This and the decision to export home directories via NFS/SMB is left up to you. If you export home directories, without further configuration, all users will get a share, that they can access on the OXSEforUCS server.
 
−
* In the next step you can start the installation with F12
 
  
−
After the installer has finished, you will be requested to reboot. Following steps remain:
+
DEBIAN_FRONTEND=noninteractive apt-get \                                       
 +
-o DPkg::Options::=--force-confold -y --force-yes \                           
 +
install univention-ox-meta-singleserver                                   
  
−
====Update to 2.2-3 (prerequisite)====
+
The univention-ox-meta-singleserver package automatically installs packages for the filtering of spam and viruses at the same time. If this is not required, the univention-ox and univention-mail-cyrus-ox packages can be installed instead of the univention-ox-meta-singleserver package.
 +
2.2 Installation on a dedicated DC slave
 +
In this installation scenario, the DC slave system acts as a standalone Open-Xchange groupware server. To start, the univention-ox-directory-integration package must be installed on the DC master in order to initiate integration in the UCS management system.
  
−
The update might take long, and the progress won't be shown on the shell.
+
DEBIAN_FRONTEND=noninteractive apt-get \                                       
 +
-o DPkg::Options::=--force-confold -y --force-yes \                           
 +
install univention-ox-directory-integration                                     
 +
   
 +
The univention-ox-meta-singleserver package is installed on the DC slave which is to be used as the groupware server. In addition, the join scripts must also be run following the installation:                                                     
  
−
You can observe the progress by:
+
DEBIAN_FRONTEND=noninteractive apt-get \                                       
−
<pre>tail -f /var/log/univention/updater.log</pre>
+
-o DPkg::Options::=--force-confold -y --force-yes \                           
 +
install univention-ox-meta-singleserver                                   
  
−
CTRL-C exits the output.
+
univention-run-join-scripts
  
−
If you are logged in via ssh, the system will refuse to update at first. You can circumvent this by typing:
+
The univention-ox-meta-singleserver package automatically installs packages for the filtering of spam and viruses. If this is not required, the univention-ox and univention-mail-cyrus-ox packages can be specified instead of the univention-ox-meta-singleserver package.
−
<pre>ucr set update22/ignoressh=yes</pre>
+
2.3  Installation in a distributed environment
 +
When installing a distributed environment, integration in the UCS management system must be performed firstly by installing univention-ox-directory-integration.
  
−
A safer solution to this is to install '''screen''' beforehand, and run the update in screen. screen is a console-window-manager, that detaches from the user-terminal, so that the update can continue, even if the controlling terminal of the user exits (e.g. triggered by the update). Installation and running screen is done by:
+
DEBIAN_FRONTEND=noninteractive apt-get \                                       
 +
-o DPkg::Options::=--force-confold -y --force-yes \                           
 +
install univention-ox-directory-integration                                     
  
−
<pre>apt-get install screen
+
The following services can then be distributed on the other UCS systems: 
−
screen</pre>
+
• IMAP server and optionally spam and virus filtering (univention-mail-cyrus-ox and optionally univention-mail-antispam-ox and univention-antivir-mail)
 +
• MySQL server (mysql-server)
 +
• OX instance (univention-ox)
 +
2.3.1  MySQL server
 +
The MySQL server is installed by installing the mysql-server package.                                                   
  
−
=====Update in shell/screen=====
+
apt-get install mysql-server                                               
−
The actual update ist performed with
 
−
<pre>
 
−
univention-updater net --updateto 2.2-3
 
−
univention-security-update net
 
−
</pre>
 
−
After the update, you can exit screen by typing '''exit''' or pressing CTRL-D.
 
  
−
It's recommended to perform the update in screen or the local console.
+
The configuration of the MySQL server should be set so that the MySQL service can be accessed via the external network interfaces. To do this, for example, the bind-address option can be set to 0.0.0.0 in the MySQL configuration file /etc/mysql/my.cnf.
  
−
=====Update via UMC=====
+
bind-address 0.0.0.0                                                           
−
Login into UMC and click on the Online-Updates module.
 
−
Under "UCS release" click on "Check for updates". Perform the Update.
 
−
Under "Security Updates" click on "Check for updates". Perform the Update.
 
  
−
Restart the machine, when the systems asks you to.
+
After the change, the MySQL service needs to be restarted:               
  
−
====One-Server-Solution comparable with OXAE====
+
/etc/init.d/mysql restart
−
After the Master installation there are no further preparations needed for the One-Server-Solution
 
  
−
====Dedicated Slave-/Backup server for OXSE====
+
In addition, the OX instances must be authorized to access the database. The following gives an example, which must be adapted to the environment at hand.                                                                 
  
−
* One UCS Master 2.2-0 installation (as describe above)
+
$ mysql                                                                           
−
* '''update to 2.2-3'''
+
mysql> GRANT ALL PRIVILEGES ON *.* TO \                                         
−
* One or more UCS Backup or Slave 2.2-0 installations (as described above)
+
'openexchange'@'ox-instance1.ucs.local' \                                     
−
* the LDAP base must be the same as for the master
+
IDENTIFIED BY 'secret';                                                       
−
* during installation, you will be asked to join the master: ensure, that DNS is running and the enter the hostname of the master and the credentials at this point.
+
mysql> GRANT ALL PRIVILEGES ON *.* TO \                                         
−
* '''update to 2.2-3'''
+
'openexchange'@'ox-instance2.ucs.local' \                                     
 +
IDENTIFIED BY 'secret';                                                       
 +
mysql> GRANT ...                                                               
 +
mysql> FLUSH PRIVILEGES;                                                       
 +
mysql> exit                         
 +
$
 +
                                         
 +
2.3.2 Active OX instance
 +
The univention-ox package must be installed on the active OX instance.     
  
−
====Installing a distributed environment====
+
DEBIAN_FRONTEND=noninteractive apt-get \                                       
 +
-o DPkg::Options::=--force-confold -y --force-yes \                           
 +
install univention-ox                                                         
  
−
For the installation of a distributed environment you must define, how the several services should be distributed on your system. In a distributed environment the following services can be installed and used on any system role (Master/Backup/Slave)
+
Then certain environment variables must be set to ensure that the join scripts run later receive the corresponding permissions. The following gives an example, which must be adapted to the environment at hand. The variable OXDB defines the MySQL server to be used by the OX instance. The corresponding password should be saved in the variable OXDBPW. The standard IMAP server must be specified in the variable OXIMAPSERVER. Hostnames need to be specified as fully qualified domain names (FQDN). It is not possible to use IP addresses.
  
−
===== Open-Xchange Server =====
+
export HISTIGNORE="export*"                                                     
−
More than one instance of Open-Xchange Server can be installed, in that case first one Open-Xchange Server instance must be installed and then bound to the UCS-domain with a join. This Open-Xchange Server instance uses a listener to synchronize with the UCS-directory service. Additional Open-Xchange Server instances can now be created easily out of existing Open-Xchange Server instances. The first instance, which takes care of the synchronization, is called 'Active-OX' (in the following example it is called ox-instance1), all additional Open-Xchange Server instances, which just access to the OX-DB, are called 'Passive-OX' (in the following example it is called ox-instance2)
+
export OXDB=oxdbserver.ucs.local                                               
 +
export OXDBPW="secret"                                                         
 +
export OXIMAPSERVER=oximapserver.ucs.local                                     
  
−
===== IMAP Server =====
+
Then the join scripts need to run:                                     
−
It is possible to install a dedicated IMAP server for every mail-domain (in the following example it is called oximapserver), but of course one IMAP server can be responsible for multiple mail-domains too. Every mail-domain has to be dedicated exactly to one IMAP server.
 
  
−
===== MySQL Server =====
+
univention-run-join-scripts
−
For a distributed environment exactly one MySQL server (in the following example it is called oxdbserver) is used, which can be located on one of the UCS-systems. MySQL replication can be established manually afterwards over the known MySQL replication mechanisms. The Open-Xchange instances must be customized therefore.
 
  
−
===Installation on all hosts===
+
Finally, the environment variable OXDBPW with the password can be unset using the following command:
−
====Register Apt-Sources====
+
unset OXDBPW
−
Please enter your Open-Xchange LDB (License database) credentials. Replace {LDB-USERNAME} by the user name and {LDB-PASSWORD} by the corresponding password.
+
2.3.3  IMAP server
 +
The IMAP server is installed by installing the univention-mail-cyrus-ox package.
  
−
ucr set repository/online/component/ox/server=software.open-xchange.com \
+
DEBIAN_FRONTEND=noninteractive apt-get \                                        
−

−
  repository/online/component/oxseforucs/password='{LDB-PASSWORD}' \
 
−
  repository/online/component/oxseforucs=enabled
 
  
−
Update the repository data afterwards
+
The spam check via spamassassin can be installed and activated by installing the univention-mail-antispam-ox package:           
−
apt-get update
 
  
−
====Assuring, that all systems are joined====
+
apt-get install univention-mail-antispam-ox                                         
−
If it is not sure that all systems are joined the join should be executed again.
+
The virus check via amavis and clamav can be installed and activated by installing the univention-antivir-mail package.                                                           
−
univention-join
 
  
−
== Installation of the component OXSEforUCS ==

−
=== One-Server solution comparable with OXAE ===
 
−
* DC Master Single Server: Installation univention-ox
 
  
−
DEBIAN_FRONTEND=noninteractive apt-get \
+
A check should then be performed to see whether all join scripts have been run successfully:                                                          
−
  -o DPkg::Options::=--force-confold -y --force-yes \
 
−
  install univention-ox-directory-integration univention-ox \

−
* DC Master: Installation univention-ox-directory-integration
 
−
apt-get install univention-ox-directory-integration
 
  
−
* Slave: Installation univention-ox
+
2.3.4 Additional passive OX instances
−
  DEBIAN_FRONTEND=noninteractive apt-get \
+
Firstly, the univention-ox package must also be installed on the additional passive OX instances.
−
  -o DPkg::Options::=--force-confold -y --force-yes \
 
−
  install univention-ox univention-mail-cyrus-ox \
 
−
  univention-ox-framework
 
  
−
If it is not sure that all systems are joined the join should be executed again.
+
DEBIAN_FRONTEND=noninteractive apt-get \                                       
−
univention-join
+
-o DPkg::Options::=--force-confold -y --force-yes \                           
 +
install univention-ox                                                         
  
−
====Installation of additional passive Open-Xchange Server instances ====
+
Then the settings can be copied from the active OX instance. This can be done, for example, using the following command:
−
Please notice that the installation described here,  '''does not support''' the future installation of further '''passive Open-Xchange Server instances'''. If this is required, please follow the Installation procedure "Installation of a distributed environment" described below and set both variables, OXDB and OXIMAPSERVER to the FQDN of the slave server.
 
  
−
===Installation of a distributed environment===
+
rsync -essh -a root@ox-instance1.ox-experten.de:/opt/open-xchange/. /opt/open-xchange/
−
====DC Master Installation====
 
−
apt-get install univention-ox-directory-integration
 
  
−
====Installation of additional Servers====
+
The FQDN of the current computer must be entered in the /opt/open-xchange/etc/groupware/usm.properties file:
−
On the other servers all dedicated packages can be installed (univention-mail-cyrus-ox, mysql-server, univention-ox-instance, univention-mail-antispam-ox)
 
  
−
* Installation of the IMAP server:
+
com.openexchange.usm.ox.url=ox-instance2.ucs.local
−
apt-get install univention-mail-cyrus-ox
 
  
−
* Installation of the MySQL server
+
The FQDN of the current computer must also be entered in the /opt/open-xchange/etc/authplugin.properties file:
  
−
apt-get install mysql-server
+
LDAP_HOST=ox-instance2.ucs.local
  
−
Set up MySQL to listen to an external interface. The among others Bind-Address of “0.0.0.0” can be replaced through the IP-addresses of the network interface:
+
Finally, the groupware must be restarted on the passive OX instance:
  
−
/etc/mysql/my.cnf
+
/etc/init.d/open-xchange-admin restart
−
bind-address 0.0.0.0
+
/etc/init.d/open-xchange-groupware restart
−
or
 
−
sed -i 's/^bind-address.*$/bind-address = 0.0.0.0/' /etc/mysql/my.cnf
 
  
−
Restart MySQL
+
2.4  OXtender for business mobility
−
/etc/init.d/mysql restart
+
The Open-Xchange OXtender for Business Mobility is an optionally available component for OXSE4UCS which enables the connection of mobile devices. The repository must be activated for it to be possible to install the corresponding packages:

Revision as of 13:39, 12 April 2010

Introduction

The Open-Xchange Server Edition for Univention Corporate Server (OXSE4UCS) includes the groupware Open-Xchange and the integration packages for Univention Corporate Server (UCS).

OXSE4UCS is tailored to professional users looking for a tried-and-tested solution for the management of their entire IT infrastructure including groupware or companies which already employ UCS and wish to expand their infrastructure with innovative groupware functions.

More detailed information on UCS can be found on the Univention GmbH website: [1].

Installation

As OXSE4UCS is an expansion pack for the Univention Corporate Server, one or more UCS server(s) must be installed firstly.

There are several possible different installation scenarios. In principle, OXSE4UCS can be installed on all UCS domain controller server roles: DC master, DC backup or DC slave. Installation on the server roles member server or base system is not currently possible.

To start, the UCS systems are installed as usual with UCS 2.3. If several systems are in the UCS domain, a check must be performed that the join procedure has been run on all servers. This is usually done at the end of the installation procedure. Further information on the installation of UCS can be found in the UCS manual: [2].

The password-protected Open-Xchange repository must be integrated on all the systems where OXSE4UCS packages are to be installed. The following Univention Configuration Registry variables (UCR variables) can be used to do this: 

export LDBUSER=myusername LDBPASS=secret
ucr set repository/online/component/ox/server=software.open-xchange.com \

repository/online/component/ox/prefix=OX6/OXSEforUCS \ repository/online/component/ox/username=$LDBUSER \ repository/online/component/ox/password=$LDBPASS \ repository/online/component/ox/version=2.2,2.3 \ repository/online/component/ox=enabled \ repository/online/component/oxseforucs/server=software.open-xchange.com \ repository/online/component/oxseforucs/prefix=OX6/OXSEforUCS \ repository/online/component/oxseforucs/username=$LDBUSER \ repository/online/component/oxseforucs/password=$LDBPASS \ repository/online/component/oxseforucs/version=2.2,2.3 \ repository/online/component/oxseforucs=enabled 

apt-get update

The access data (myusername and secret) are created when the Open-Xchange licence is activated and must be adapted here accordingly. 2.1 Installation on a DC master When installing OXSE4UCS on a DC master, only the univention-ox-meta-singleserver package requires installing. This can be performed via the Univention Management Console or on the command line:

DEBIAN_FRONTEND=noninteractive apt-get \ -o DPkg::Options::=--force-confold -y --force-yes \ install univention-ox-meta-singleserver

The univention-ox-meta-singleserver package automatically installs packages for the filtering of spam and viruses at the same time. If this is not required, the univention-ox and univention-mail-cyrus-ox packages can be installed instead of the univention-ox-meta-singleserver package. 2.2 Installation on a dedicated DC slave In this installation scenario, the DC slave system acts as a standalone Open-Xchange groupware server. To start, the univention-ox-directory-integration package must be installed on the DC master in order to initiate integration in the UCS management system.

DEBIAN_FRONTEND=noninteractive apt-get \ -o DPkg::Options::=--force-confold -y --force-yes \ install univention-ox-directory-integration

The univention-ox-meta-singleserver package is installed on the DC slave which is to be used as the groupware server. In addition, the join scripts must also be run following the installation:

DEBIAN_FRONTEND=noninteractive apt-get \ -o DPkg::Options::=--force-confold -y --force-yes \ install univention-ox-meta-singleserver

univention-run-join-scripts

The univention-ox-meta-singleserver package automatically installs packages for the filtering of spam and viruses. If this is not required, the univention-ox and univention-mail-cyrus-ox packages can be specified instead of the univention-ox-meta-singleserver package. 2.3 Installation in a distributed environment When installing a distributed environment, integration in the UCS management system must be performed firstly by installing univention-ox-directory-integration.

DEBIAN_FRONTEND=noninteractive apt-get \ -o DPkg::Options::=--force-confold -y --force-yes \ install univention-ox-directory-integration

The following services can then be distributed on the other UCS systems: • IMAP server and optionally spam and virus filtering (univention-mail-cyrus-ox and optionally univention-mail-antispam-ox and univention-antivir-mail) • MySQL server (mysql-server) • OX instance (univention-ox) 2.3.1 MySQL server The MySQL server is installed by installing the mysql-server package.

apt-get install mysql-server

The configuration of the MySQL server should be set so that the MySQL service can be accessed via the external network interfaces. To do this, for example, the bind-address option can be set to 0.0.0.0 in the MySQL configuration file /etc/mysql/my.cnf.

bind-address 0.0.0.0

After the change, the MySQL service needs to be restarted:

/etc/init.d/mysql restart

In addition, the OX instances must be authorized to access the database. The following gives an example, which must be adapted to the environment at hand.

$ mysql mysql> GRANT ALL PRIVILEGES ON *.* TO \ 

'openexchange'@'ox-instance1.ucs.local' \                                       
IDENTIFIED BY 'secret';

mysql> GRANT ALL PRIVILEGES ON *.* TO \ 

'openexchange'@'ox-instance2.ucs.local' \                                       
IDENTIFIED BY 'secret';

mysql> GRANT ... mysql> FLUSH PRIVILEGES; mysql> exit $

2.3.2 Active OX instance The univention-ox package must be installed on the active OX instance.

DEBIAN_FRONTEND=noninteractive apt-get \ -o DPkg::Options::=--force-confold -y --force-yes \ install univention-ox

Then certain environment variables must be set to ensure that the join scripts run later receive the corresponding permissions. The following gives an example, which must be adapted to the environment at hand. The variable OXDB defines the MySQL server to be used by the OX instance. The corresponding password should be saved in the variable OXDBPW. The standard IMAP server must be specified in the variable OXIMAPSERVER. Hostnames need to be specified as fully qualified domain names (FQDN). It is not possible to use IP addresses.

export HISTIGNORE="export*" export OXDB=oxdbserver.ucs.local export OXDBPW="secret" export OXIMAPSERVER=oximapserver.ucs.local

Then the join scripts need to run:

univention-run-join-scripts

Finally, the environment variable OXDBPW with the password can be unset using the following command: unset OXDBPW 2.3.3 IMAP server The IMAP server is installed by installing the univention-mail-cyrus-ox package.

DEBIAN_FRONTEND=noninteractive apt-get \ -o DPkg::Options::=--force-confold -y --force-yes \ install univention-mail-cyrus-ox

The spam check via spamassassin can be installed and activated by installing the univention-mail-antispam-ox package:

apt-get install univention-mail-antispam-ox The virus check via amavis and clamav can be installed and activated by installing the univention-antivir-mail package.

apt-get install univention-antivir-mail

A check should then be performed to see whether all join scripts have been run successfully:

univention-run-join-scripts

2.3.4 Additional passive OX instances Firstly, the univention-ox package must also be installed on the additional passive OX instances.

DEBIAN_FRONTEND=noninteractive apt-get \ -o DPkg::Options::=--force-confold -y --force-yes \ install univention-ox

Then the settings can be copied from the active OX instance. This can be done, for example, using the following command:

rsync -essh -a root@ox-instance1.ox-experten.de:/opt/open-xchange/. /opt/open-xchange/

The FQDN of the current computer must be entered in the /opt/open-xchange/etc/groupware/usm.properties file:

com.openexchange.usm.ox.url=ox-instance2.ucs.local

The FQDN of the current computer must also be entered in the /opt/open-xchange/etc/authplugin.properties file:

LDAP_HOST=ox-instance2.ucs.local

Finally, the groupware must be restarted on the passive OX instance:

/etc/init.d/open-xchange-admin restart /etc/init.d/open-xchange-groupware restart

2.4 OXtender for business mobility The Open-Xchange OXtender for Business Mobility is an optionally available component for OXSE4UCS which enables the connection of mobile devices. The repository must be activated for it to be possible to install the corresponding packages:

export LDBUSER=ldbuser LDBPASS=lsbpass ucr set repository/online/component/oxmobility/server=software.open-xchange.com \ repository/online/component/oxmobility/prefix=OX6/OXSEforUCS \ repository/online/component/oxmobility/username=$LDBUSER \ repository/online/component/oxmobility/password=$LDBPASS \ repository/online/component/oxmobility/version=2.2,2.3 \ repository/online/component/oxmobility=enabled

apt-get update

Installing the univention-ox-usm-ox package installs the Oxtender for Business Mobility on the OXSE4UCS system.

apt-get install univention-ox-usm-ox

If the target system is neither a DC master nor a DC backup system, the univention-ox-usm-udm package should also be installed on the DC master.

apt-get install univention-ox-usm-udm

3 Updating To update a UCS 2.2 system with OXSE4UCS 6.12 or 6.14 to UCS 2.3, the following variables must be set before the update.

ucr set repository/online/component/ox/version=2.2,2.3 \ 

       repository/online/component/oxseforucs/version=2.2,2.3

The system can then be updated as usual for UCS using the univention-updater net command or the UMC module Online Update. 4 Administration 4.1 User and group management New users and groups can be created using the Univention Directory Manager (UDM). The UDM can be accessed on the DC master via a web browser at https://<IP-Adresse des DC Master>/udm/. It is possible to log in as the Administrator user using the password specified during the installation. When creating a user, the open-xchange groupware account user template should be selected. This preselects all Open-Xchange specific settings. 4.2 System messages The mail/alias/root UCS variable must be set so that system messages can be delivered. To do this, either a new account can be created or, alternatively, oxadmin@DOMAIN is provided for this purpose:

ucr set mail/alias/root=oxadmin@ucs.local newaliases /etc/init.d/postfix reload

It is possible to log in as the oxadmin user in the Open-Xchange web interface using the password from the /etc/ox-secrets/context10.secret file.
