This is the openSUSE package for GNUHealth. Starting with openSUSE Leap 42.2, it is shipped with the standard distribution. It was build to simplify the installation and maintenance of a system, to make it useable for 'end-users' as well.
It has shown that this can cause a lot of trouble with dependencies (other software packages that are required to run GNUHealth and the Tryton Server), as they may be named slightly different in your Linux-distribution, or are just not listed.
To avoid hassle for each and every end user, openSUSE uses the Open Build Service [1] to create a package where all dependencies are resolved for you.
As a consequence, you install the package 'gnuhealth' with the openSUSE package manager, and the system does the rest for you. See [2] for installation advise.
In GNU Health installation from source, the program gnuhealth_control is used to perform updates, maintenance etc. The openSUSE packages come with a modified gnuhealth_control to distinguish between activities performed by system tools (zypper) and those that safely can be handled by gnuhealth_control. Try it, its save!
Tryton [3] is the technical backend for GNUHealth. Tryton can run as ERP-System on its own. For the reasons explained under 1) , Tryton is build as well as package for openSUSE, following the same philosophy. See [4]for details.
Nevertheless, you can use gnuhealth-control to create database backups, install languages and updates. Make sure the version of gnuhealth-control ends on -openSUSE. gnuhealth-control should run as root, if in doubt.
Starting with GNU Health 3.2, GNU Health comes with its own WebDAV-Server that can be used for shared calendars. In order to enable the WebDAV server, it comes with a systemd-service. As input parameter for the service the database-name on which to operate must be passed. Say your database is called mydb, invoke the service with
In order to make use of GNUHealth's capabilities to digitally sign documents, you need to create a PGP-key for the user logged in to the operating system.
From the start menu, start the program Kgpg and follow the instructions, it will guide you through the process of key generation. Choose the maximal key length (4096).
Use a passphrase with Capital letters, small letters, numbers and special characters (like %$§ etc) and have at least 12 digits for the passphrase - the more, the better.
Keep the passphrase in a secure location, and take a backup of the PGP keys (located in ~/gnupg - in the live CD this is /home/gnuhealth/.gnupg ).
