Kolab Groupware is a free and open source web-based groupware application. Its features consist of email communications, events, appointments, tasks, file cloud, contacts, and more. In this tutorial, you will learn how to install the latest version of Kolab Groupware on Debian 8.
A Vultr Debian 8 server instance.
A sudo user.
Before installing any packages on the Debian server instance, it is recommended to update the system. Log into the system using the sudo user, then run the following commands to update the system.
sudo apt-get update sudo apt-get -y upgrade
It is important that your system has an FQDN (full qualified domain name) for a hostname that resolves back to the server through DNS.
sudo hostname kolab.example.com
/etc/hosts file using your favorite editor.
sudo nano /etc/hosts
Enter the IP address and full FQDN of your server at the end of the file. For example:
We can now add the Kolab Groupware repository to the system. Run the following command to create a new repository file.
sudo nano /etc/apt/sources.list.d/kolab.list
Add the following lines into the file.
deb http://obs.kolabsys.com/repositories/Kolab:/16/Debian_8.0/ ./ deb-src http://obs.kolabsys.com/repositories/Kolab:/16/Debian_8.0/ ./
Add the GPG key.
wget -q -O- https://ssl.kolabsys.com/community.asc | sudo apt-key add -
You will need to give the Kolab repository higher priority over the default Debian repository. Create a new preferences file.
sudo nano /etc/apt/preferences.d/kolab
Populate the file contents.
Package: * Pin: origin obs.kolabsys.com Pin-Priority: 501
Update the repository metadata using the following command.
sudo apt-get update
Install Kolab Groupware.
sudo apt-get -y install kolab
During installation, you will be asked for a new MySQL password. The installer will also ask for Postfix configuration, choose
Internet Site and provide your FQDN for the hostname.
Run the following command to configure the Kolab for first time. You will need to set a few administrator passwords for LDAP, Cyrus, and Kolab during this step. You will also need to set the domain name and MySQL database being used.
The following questions will be asked during setup, please follow the instructions provided along with them.
