Install Kopano on Debian 8

What is Kopano?

Kopano is a fork (a spin-off) of Zarafa. Some components have been adopted, others written from scratch. Kopano is open source, offers a wide range of functions and has a modular structure:

  • core (base for all other components)
  • webapp (fully equipped web GUI a la Outlook Web Access)
  • files (integration of various cloud services, for example: Owncloud / Nextcloud)
  • Web meetings
  • deskapp (Full desktop email client based on a modified Chromium browser! -> Send to … works! -> no Outlook!)
  • mdm (mobile device management)

Operating system platform

As operating system I have (as so often) Debian GNU Linux “Jessie” in use. The base of the installation is basically a LAMP installation. PHP should run as mod_php. Apart from that, there are of course some dependencies that need to be met when installing Kopano.

Sounds complicated, but it is not!

Of course, some other distributions are also supported, such as: OpenSuse, Ubuntu, Fedora, RHEL, SLE ….

If you like working “from scratch”, you can also compile everything yourself. However, this is “not my construction site” ;-).

Where do you get the packages from Kopano?

The community edition packages can be downloaded from the website . Each directory corresponds to a module (core, deskapp, files …).

Community Edition vs. subscription

If Kopano Community Edition is used, the packages are given in the form of a bleeding edge variant. The packages are nightly-builds.

The packages can / must be downloaded via wget . The installation is done by dpkg .

If a subscription is available , it will be more convenient, because then the Kopano repository can be integrated, which means that the entire package management can be done via apt-get .

Mobile phone synchronization Z-Push

Smartphone users are not too short. Per z-push , which is available for free, ActiveSync is implemented.

Installation LAMP

I’m not going to talk about installing Debian GNU Linux “from scratch” here. I assume that we start from a basic installation.

Since it is also necessary to provide a database and to edit various settings, I also install the phpmyadmin package .

apt-get install mysql-server apache2 phpmyadmin

MySQL facility

There is not much to say about that. Apt-get asks during the setup for a password for the MySQL superadmin “root”. You should definitely set a password here.

As a web server Apache2 is used. This should also be selected in the setup dialog.

Finally , the command mysql_secure_installation should be called. (Remove anonymous user (yes), Dissalid root login remotely (yes), remove Testdb (yes), Reload privilege tables now (yes).


For easier management of databases, phpmyadmin will be installed. Again, the setup is completed quickly. After completing the question “Configuring the database for phpmyadmin with dbconfig-common” with YES, entering the MySQL root password and confirming the question for a password for the phpmyadmin user with a return, the installation is complete.

Phpmyadmin should now be accessible via the Internet browser.

Thus, we have created a LAMP basis and can now dedicate ourselves to the Kopanoinstallation.

Install Kopano

Download packages

Kopano’s packages can be downloaded via wget if you do not have a subscription. (Note: subscribers can access the packages directly via apt-get.)

When working with wget, is the address of choice.

On the Linux server itself, you can create a directory to download the packages into, or you can access the / tmp directory.

cd / tmp






wget .0.20_16-Debian_8.0-all.tar.gz

Note: The file names change daily (version number -> da nightlies)

After downloading, the * .tar.gz files will be unpacked. Per unpacked file, a corresponding subdirectory is automatically created.

Unzip and install the Kopano-core

tar xfvz core-8.4.0 ~ 35_19.1-Debian_8.0-amd64.tar.gz

cd core-8.4.0 ~ 35_19.1-Debian_8.0-amd64

dpkg -i * .deb

The installation attempt fails because there are unresolved dependencies. In fact, you get the message: “Errors occurred while editing:”

Clean up unresolved dependencies

Apt would not be apt if there were no easy solution to this circumstance.

apt-get install -f

This command will “trace” all missing packets.

Kopano-core – second attempt

At the Instano of Kopano-Core no unresolved dependencies should be displayed anymore.

Kopano Webapp

When installing the webapp is now the same procedure, as in “Core”. Unpack the tag.gz file, change to the directory where the unpacked .deb files are located + install with dpkg.

tar xvfz webapp-
cd webapp-
dpkg -i * .deb

Again, missing dependencies will lead to problems during installation. Again, apt-get solves the problem.

apt-get -f install

Finally, the installation of the webapp is no longer a problem. (In the directory where the unpacked files of the webapp are):

dpkg -i * .deb

In order to activate the configuration of the Webbapp, the Apache web server must be restarted or the configuration must be read in again.

service apache2 reload


service apache2 restart

Is the webapp available?

This can be tested very easily using a browser.

http: // <FQDN or IP> / webapp

The basic installation of Kopano-Core and the webapp are now complete. But this is so far purely the frontend! The database connection is not yet available.

Set up MySQL database

By phpmyadmin this project is not too big a problem.

First, create a new database.

and a user

The conclusion is the assignment of user authorizations. (Database kopano / user kopano)

Customize the Kopano-Core configuration file

For Kopano to get something from the database, the configuration file has to be adjusted.

vim /etc/kopano/server.cfg

In the MYSQL SETTINGS section   (for database_engine = mysql) , the host, DB, DB user and DB password must be stored.

Start Kopano Server

The start of the server should now cause the previously created database to be filled with the necessary tables / fields.

First we stop a running Kopano server.

service copano-server stop

The start

service copano-server start

and the following status check, should give the following picture.

Kopano user

The Kopanobenutzer come in this configuration from the MySQL database and must be created via the Linux console.

Subsequently, a user “gestl” including mail address is created. The user is an administrator and therefore also receives a parameter along the way (-a1).

 kopano-admin -c gestl -p 12init34 -e -f “Daniel Gestl” -a1

Login to the webapp

In order to check whether the configuration work was successful, the login attempt is finally completed.

http: // <FQDN / IP> / webapp

As you can see, the installation is no magic. However, the integration of Postfix is ​​still missing, so that emails can be sent and received. (… and a little finetuning).

I will deal with that in a second article on “Kopano”.

PS: Kopano can do much more!
