Groupware servers are meant to operate on a server platform. You must install the server version of Ubuntu/Ubuntu first. Read Servers.
Kolab is the most comprehensive open-source groupware solution available and is distributed as a multi-platform solution. (It integrates easily with both Ubuntu (including Evolution) and KDE/Kubuntu (including Kontact).) It is free and open source with a GPL license (unlike other groupware solutions), yet enterprise support is also available. It is scalable to large organizations and is Outlook (MS-Exchange) and Mozilla compatible. This is a German package, however, and documentation in English can occasionally be limited. The Kolab website provides its own instructions for installation from source (currently v. 2.2). Version 2.2 includes the Horde web interface.
- Note: Kolab uses its own server components, and it is best to run Kolab on a dedicated server. However, it is possible to run other servers on the same machine, as long as you choose alternate ports if the server modules conflict.
- Install the compiler and other necessary stuff:
sudo apt-get install build-essential
Kolab Ubuntu package
- There is an Ubuntu/Kubuntu package for the new version of Kolab (v. 2.2), but no documentation support for it yet exists. Install:
sudo apt-get install kolabd
Manual Kolab installation
- Make a directory for the Kolab installation and make it universally accessible:
sudo cd / sudo mkdir /kolab sudo chmod 777 /kolab
- Optional: If you wish to mount kolab in its own partition, then create a new partition (using Gparted, for example). Figure out the device name of your extra partition:
sudo fdisk -l
- It should be something like /dev/sda3.
- Mount /dev/sda3 (or whatever your partition is) as /kolab by editing /etc/fstab:
sudo nano /etc/fstab
- and adding the line:
/dev/sda3 /kolab ext3 defaults,rw 0 0
- then reboot and make sure there are no errors.
- Make a directory into which to download kolab:
cd /tmp mkdir /kolabtmp
- Download all the current Kolab files:
cd /tmp/kolabtmp wget -r -l1 -nd --no-parent http://files.kolab.org/server/release/kolab-server-2.2.2/sources/
- Install Kolab (as root using sudo -s):
sudo -s sh install-kolab.sh 2>&1 | tee kolab-install.log
- Reboot your system.
- Stop Kolab services and run the configuration utility:
sudo /kolab/bin/openpkg rc all stop sudo /kolab/sbin/kolab_bootstrap -b
- Obviously, you should know all your details, such as your fully qualified host name (which you can determine from hostname -f), domain details, etc., before doing this step. If you are not familiar with OpenLDAPand LDAP basics, you should learn about it, as Kolab uses the slapd OpenLDAP server daemon.
- Restart all Kolab services:
sudo /kolab/bin/openpkg rc all start
- Login to the web administrator interface using "manager" and the password you set at bootstrap configuration:
Citadel is a turn-key fully open source groupware solution (that is also Kolab compliant) with a structure rooted in bulletin-board systems, and is therefore user friendly. Installation instructions are found at the website.
eGroupware is a robust and stable free open source groupware solution (with GPL license) based on the LAMP stack (the default server stack included with Ubuntu Server) and the Postfix mail server (both of which should be installed first). There is a new version recently available, with a new corporate sponsor in Germany and a commercial enterprise version. Compatibility with many clients has been improved. Egroupware provides the easiest installation and quickest setup time of all groupware solutions. Much of the documentation for the current version, unfortunately, is not in English.
