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.

Supported version

SME Server


See Includes known issues updating from SME10.0


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 or URL

When you select the URL option the required URL is provided as a mirrorlist. A mirrorlist of smeupdates is also provided so you do not have to do updates right after install.

Next step will be to select the packages to install, i.e. minimal environment to get a fully functional SME 10. Failure to do this step, will leave you with a CentOS 7 minimal.

Unless you know what you are doing do not enter in the partitioning tool, doing so will erase SME preconfigured partitions, and using the auto partitioning option in this tool will give you CentOS default, in other word full use of all disks with LVM without any raid.

Final step will be to start installation.

If you have special needs, or need to fully automatized the installer, you can create your own kickstart script and use it when loading the iso.
