Service Desk module

The Service Desk module is provided as a ZIP file. It must be unpacked on your existing web server in a directory that is accessible via an URL. The web server must be able to execute PHP code.

Copy the file "config-sample.php" to "config.php" and adjust the URL for the REST interface of your Allegra server. Copy the files "footer-sample.php", "header-sample.php" and "custom-sample.php" into the corresponding files without "-sample" and make adjustments if necessary.

For more documentation please visit our documentation area.

Update the service desk module

To update the module go to the directory where you installed it. Execute the file "update.php" in it.

Installation on Ubuntu 18.04

In just a few minutes you can install a fully functional system on an Ubuntu 18.04 LTS Linux server with a Postgres database system:

  • Download the installation script and execute it with the desired context name as a parameter.
  • Example: sudo ./ allegra
  • Shortly afterwards you can reach your installation at

Please note that port 80 has to be free and that there must not be an Apache Tomcat and Postgres system installed. Thus this script is particularly useful for a cloud installation.

First you need to install a proper environment:

  • Install an Apache Tomcat 9.0 or newer as application server
  • Install a MySQL database (or Oracle, DB2, Postgres, Firebird)
