Introduction

• The Controller can be installed on Linux systems without use of an installer by extracting a .tar.gz archive.
• The Controller can be installed on Windows systems
  • without use of an installer by extracting a .zip archive. This allows a portable installation that requires no administrative privileges or
  • by running the Controller installer in headless mode or
  • by running the graphical installer see JS7 - Controller - Using the Windows Graphical Installer.

Prerequisites

• A Java Runtime Environment starting from version 1.8 is required. For details see Which Java versions is JobScheduler available for?
• Technically the Controller can be operated in any Unix environment. However, the JS7 - Platforms include support for Controller operation with Linux.

Download

• Download the Controller archive for the target system from the JS7 - Download page.
  
  • For Unix systems:
    • A .tar.gz archive is available that is extracted to create the Controller's directory structure (see below).
      
      • js7_controller_unix.<release>.tar.gz
  • For Windows systems:
    • A .zip archive is available that will create the Controller's directory structure when it is extracted (see below).
      • js7_controller_windows.<release>.zip
    • A .zip archive including the installer is available that can be used to run the installer in headless mode.
      • js7_controller_windows_installer.<release>.zip

        • controller.conf (general Controller configuration)
        • lib (optional directory for JDBC Drivers and licensed binary code)
        • license (optional directory for license certificate files)
        • private (directory for security related configuration files)
          • private.conf-example (security related configuration)
            • For setting up HTTPS connections - see JS7 - Controller Configuration Items
            • For setting up authentication and digital signature checks
      • logs (directory for log files)
      • state (directory for journal files)
• On Windows Systems:
  • You have to modify the directory permissions for the above .\logs and .\service directories if you extract the Controller to, forexample: C:\Program Files.
    • This step is not required if you extract the Controller e.g. to C:\ProgamData.

    • Start a command prompt with elevated administrative rights and execute, for example:

      Allow full acces for "Users" on .\service and .\logs directories

      cd "path\to\installation-directory"
      icacls "service" /L /grant *S-1-5-32-545:(OI)(CI)F
      icacls "logs" /L /grant *S-1-5-32-545:(OI)(CI)F

• To start the Controller you can use the commands explained with the JS7 - Controller - Command Line Operation article or your can automate startup from the instructions provided by the below chapter "Automated Startup and Shutdown".

Update

Preparation

• Stop the JS7 Controller instance.
• Prepare to rollback in case the update of the JS7 Controller is not successful:
  • Make a backup of the Controller's installation and configuration directories, e.g. by creating a .tar.gz/.zip archive.
    
    • Installation Directory:
      • The default installation directory for the Controller is:

        • /opt/sos-berlin.com/js7/controller/<controller-id> for Unix systems,

        • C:\Program Files\sos-berlin.com\js7\controller\<controller-id> for Windows systems.
    • Configuration Directory
      • The default configuration directory for the Controller is:
        • /home/sos/sos-berlin.com/js7/controller/<controller-id> for Unix systems,
        • C:\ProgramData\sos-berlin.com\js7\controller\<controller-id> for Windows systems.

Running the Update

The update of the JS7 Controller is performed from the same download archive as used for any fresh installation.

• When extracting files to a location that has already been used then existing files with the same name will be overwritten. Files added by the user will remain in place
  
  • This is particularly true for the Controller Start Script ./bin/controller.sh|cmd which should not be modified by users.
• The .tar.gz/.zip archive includes Java libraries in the ./lib directory that ships with file names that are unique to every Controller release.
  • Therefore, before extracting files, rename or remove an existing ./lib directory in order to store libraries from the current Controller release only in this directory.

Installation by Windows Installer in Headless Mode

The Controller installer is available for Windows systems only. 

• To run the Windows installer in graphical mode see JS7 - Controller - Installation Using the Windows Graphical Installer.
• To run the Windows installer in headless mode consider the information below.

Installation

After extraction of the installer .zip archive the directory structure will include:

• controller_install.xml (installer response file)
• install_controller.txt (installation notes)
• js7_controller_windows.<release>.jar (installer library for a given release)
• license.txt, license.html (copy of JS7 JobScheduler Commercial License Agreement)
• setup.cmd (installer script)

Installer Response File

• The Controller installation uses the controller_install.xml response file, which includes parameters such as the installation path, ports, etc.
  • For a fresh installation the installer response file is included with the downloaded archive.
  • The default location of the controller_install.xml file from a previous installation is:
    
    • C:\Program Files\sos-berlin.com\js7\controller\<controller-id>
  • The <controller-id> is a unique identifier for a Controller which you specify from the installer response file:
    • You are free to choose an identifier, e.g. controller-test, controller-prod if you intend to run a separate Controller for each environment. Upper case and lower case characters are considered, the characters a-z, A-Z, 0-9, underscore and hyphen are allowed. Spaces are not allowed in a Controller ID.
    • If you intend to operate a Controller cluster then both Controller instances have to use the same Controller ID.

• Customers with a commercial license should choose the relevant license option and specify the location of the license key with the installer response file.

• The controller_install.xml file is explained with the code listing below. The comments included are intended to be self-explanatory.
  Download: controller_install.xml

Running the Installer

• Running the installer of the JS7 Controller on Windows systems:

  Running the installer of JS7 Controller on Windows systems

  C:\temp\controller.[release]> setup.cmd controller_install.xml

Directory Structure

After installation the resulting directory structure will be similar to that described in the Installation from .tar.gz/.zip Archive chapter above.

Directories for installation and configuration of the Controller might differ.

Update

Preparation

• Stop the JS7 Controller instance.
• Prepare to rollback in case the update of the JS7 Controller is not successful.
  • Make a backup of the Controller's installation directory and configuration directory, e.g. by creating a .zip archive.
    • Installation Directory:
      • The default installation directory for the Controller instance is
        
        • C:\Program Files\sos-berlin.com\js7\controller\<controller-id>
    • Configuration Directory
      • The default configuration directory for the Controller instance is
        
        • C:\ProgramData\sos-berlin.com\js7\controller\<controller-id>

Running the Update

The update procedure makes use of the same installer response file as described for a fresh installation.

Steps to run the installer are the same as described for a fresh installation.

Installation Log

The installer creates a log file in the directory specified in the JS7_CONTROLLER_LOGS environment variable or in the logs sub-folder of the Controller configuration directory.

• The default location of the logs directory for the Controller is
  
  • C:\ProgramData\sos-berlin.com\js7\controller\<controller-id>
• Installation log files are named according to the pattern Install_V<release>_<date-time>_....log where <release> is the release number and <date-time> refers to the point in time of  installation.
• For further information about logging see JS7 - Logging

Rollback

Rollback Installation from .tar.gz/.zip Archive

• To rollback the installation of a JS7 Controller instance, remove the newly created installation and configuration directories of the JS7 Controller.
• Restore the directories from a previous backup, e.g. by extracting the respective .tar.gz/.zip backup archives to the installation and configuration directories.

Rollback Installation by Windows Installer in Headless Mode

• To perform the rollback of the JS7 Controller instance run the uninstaller from the command line.
  • The default location of the uninstall.cmd file is:
    
    • C:\Program Files\sos-berlin.com\js7\controller\<controller-id>\Uninstaller
• Restore from a previous backup, e.g. by extracting the .tar.gz/.zip archive to the installation directory and configuration directory.
• Re-install the Windows Service from the command line:
  • Switch to the .\bin directory for the Controller from the command line
    • The default location of the .\bin directory is:
      

      • C:\Program Files\sos-berlin.com\js7\controller\<controller-id>\bin

  • Run the following command to install the Controller's Windows Service. 

    controller.cmd install-service

Automated Startup and Shutdown

For Unix systems startup and shutdown configurations apply that are executed by the root account e.g. from /etc/init.d scripts and by use of systemd.

• 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 / 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.

• Consider to assign a service account to the JS7 Controller service with the Windows Service Panel.
• Consider to allow the JS7 Controller service to be automatically started on server startup.
