The productive installation has currently been tested under the following Debian-based Linux distributions, which all instructions and provided scripts are based on:
Debian 10 (Buster)
Debian 11 (Bullseye)
Ubuntu 20.04 LTS (Focal Fossa)
Ubuntu 22.04 LTS (Jammy Jellyfish)
It is generally recommended to use the latest version of the respective distribution.
This section describes how to install, update and backup Kadi4Mat in a production environment using a simple, single-machine setup. This type of setup should already be sufficient for most cases to install a Kadi4Mat instance for light to medium use.
The required hardware for this setup may vary for each use case, especially related to storage for the database, the search index and locally stored files. As a general rule of thumb for RAM and CPU, a minimum of 16 GB RAM and a decent CPU with 8 cores should be sufficient for this type of setup.
Keep in mind that, for production deployments, there are other aspects to consider as well, e.g. securing the server the application and services are running on by keeping dependent packages up to date, using a firewall, etc.
There are currently two ways to perform the installation: installation via setup script and manual installation. When using the former, it is still recommended to check out the manual installation instructions, as all the necessary steps are described in much more detail, which is also recommended when planning to deploy a more intricate, multi-machine setup.
After the installation, please make sure to at least check out the configuration reference as well, which explains how to further configure and customize Kadi4Mat, especially with regard to user authentication.
