• First of all, you don't need to read this article in all its parts. For most situations it is sufficient to check the prerequisites, download the software and run the installer that will guide you.
• In this article you find the details about available installer options, updates and rollback for interested parties.
• The Controller can be installed by use of the graphical installer, for headless installation see JS7 - Controller - Headless Installation on Linux /and Windows.

Prerequisites

• A Java Runtime Environment 1.8 or newer is required. For details see Which Java versions is JobScheduler available for?
• It is necessary that a time service is operated on the server which hosts the Controller. This is to synchronize the system clock's time.
• Technically the Controller can be operated in any Unix environment. Note, however, that the JS7 - Platforms article describes support for Controller operation in more detail.

...

• The installer can be run in graphical mode or in headless mode, see JS7 - Controller - Headless Installation on Linux /and Windows.

• The installer asks for elevated administrative privileges, therefore it is not required to change the permissions in the .\service directory and the installer sets read/write permissions for the .\logs directory.
• After the installation you will find
  
  • a Windows Service "SOS JS7 Controller -id=<controller-id>"
  • an executable file .\service\js7_controller_<controller-id>.exe that is started by the Windows Service.

...

• Consider use of the JS7_CONTROLLER_USER environment variable from the ./bin/controller_instance.sh script to run a Controller that is started by root for a different user account.
• For use with systemd find a sample service file from ./bin/controller.service-example.
• For details see JS7 - systemd Service Files for automated Startup / and Shutdown with Unix Systems

For Windows systems operation of the Controller by a Windows Service is recommended as such services can be configured to start/stop automatically on server startup and shutdown.
