The Koozali SME Server project

The Koozali Foundation Inc. is a nonprofit corporation that governs the open source Koozali SME Server project. Koozali SME Server is a stable, secure and easy to use/manage linux server that provides common server functionalities out of the box. Many open source contributions are available that can extend the default server functionality making Koozali SME Server an even more powerful and flexible business server solution. Thousands of Koozali SME Severs have been deployed as real or virtual servers and in the cloud to serve many small to medium enterprises, and this number is growing day by day. The Koozali SME Server is free to use but it takes a lot of effort and money to develop, make, and maintain. We therefore ask you for your considerations.

Recommended version

SME Server 9.0 64-bit.


When installing the netinstall ISO, you will be asked some basic questions (check the media, languages, keyboard layout etc.), followed by the question for the location of installation files. The options are:

  • CD/DVD
  • Hard drive
  • NFS
  • URL

When you select the URL option the required URL is:

The URL must be adapted to the specific SME Server version and architecture. (overview of versions and architecture).


When updates become available you will be able to update a previous version of an iso using zsync, run the command from the same directory as your existing iso. zsync uses a control file to determine whether any blocks in the file are already known to the downloader, and only downloads the new blocks. If you don't have a previous iso zsync is still a good option, it will recover an interrupted download.

To install ZSync you need to ensure you have the Dag repositories enabled. See here: Dag, then issue the following commands:

yum install zsync --enablerepo=dag

Reboot not required

cp smeserver-8.2-i386.iso smeserver-8.2.1-i386.iso [if you have a previous .iso]


To upgrade your existing SME Server to SME Server 9.0, see Upgrading
