Introduction

  • The Controller is installed on Linux systems without use of an installer by extracting a .tar.gz archive.
    • Technically the Controller can be operated for any Unix environment, however, the JS7 - Platforms include support for Controller operation with Linux.
  • 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.
    • by running the Controller installer in headless mode.

Prerequisites

Download

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

Installation from tarball/zip Archive

Installation

  • Extract the downloaded archive to a directory.
  • The resulting directory structure includes (only files and folders directly relevant):
    • controller
      • bin
        • controller.cmd|sh
          • The Start Script for Windows/Unix platforms
        • controller_watchdog.cmd|sh
          • Restarts the Controller for Windows/Unix platforms
        • environment_variables.cmd|sh
          • Sets environment variables for the JS7 Controller
      • lib
        • The directory for Java libraries
      • service (for operation as a Windows Service)
        • amd64 (directory)
        • manager (directory)
        • x86 (directory)
        • install_controller_windows_service.cmd
        • js7_controller_<Controller ID>.exe
        • js7_controller_<Controller ID>w.exe
        • LICENSE.txt
        • NOTICE.txt
        • RELEASE-NOTES.txt
        • set_java_home_for_jetty_windows_service.cmd
        • uninstall_controller_windows_service.cmd
      • user_bin
      • Uninstaller (Windows only, the empty directory remains in place after uninstall)
        • install.log
        • js7.ico
        • shortcut.vbs
        • uninstall.cmd
        • uninstall_prepare.cmd
        • uninstaller.jar
      • var
        • logs
        • config
        • state
    • On Windows Systems:
      • You have to modify the directory permissions for the above .\logs and .\service directories if you extracted the Controller to e.g. 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 e.g.

          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 

Update

Preparation

  • Stop the JS7 Controller instance.
  • Prepare to rollback in case that the update of the JS7 Controller is not successful:
    • Take a backup of the Controller's installation directory and configuration directory, 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 the same location then existing files with the same name will be overwritten. Files added by the user remain in place.
    • This is particularly true for the Controller Start Script ./bin/controller.sh|cmd that should not be modified by users.
  • The tarball/zip archive includes Java libraries in the ./lib directory that ship with unique file names per Controller release.
    • Therefore, before extracting files, rename or remove an existing ./lib directory in order to store libraries from the current Controller release only to this directory.

Installation from Windows Installer in Headless Mode

The installer is available for Windows systems only. 

Installation

Installer Response File

  • The Controller installation makes use the controller_install.xml response file that 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_install.xml file is explained with the code listing below. The comments included are intended to be self-explanatory.  

    Configuration of the controller_install.xml file 
    <?xml version="1.0" encoding="UTF-8" standalone="no"?>

Running the Installer

  • Running the installer of JS7 Controller on Windows systems:

    Running the installer of JS7 Controller on Windows systems
    C:\temp\controller.[release]> setup.cmd controller_install.xml

Installation Log

The installer creates a log file in the directory that is pointed to by the environment variable JS7_CONTROLLER_LOGS or in the logs sub-directory 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.

Update

Preparation

  • Stop the JS7 Controller instance.
  • Prepare to rollback in case that the update of the JS7 Controller is not successful.
    • Take 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 is
          • C:\Program Files\sos-berlin.com\js7\controller\<controller-id>
      • Configuration Directory
        • The default configuration directory for the Controller 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 explained for a fresh installation.

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

Rollback

Rollback from tarball/zip Archive Installation

  • To rollback the installation of a JS7 Controller instance remove the newly created installation directory and configuration directory 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 directory and configuration directory.

Rollback from Installation with Headless Installer for Windows

  • 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 below command that will install the Controller's Windows Service. 

      controller.cmd install-service [--http-port=<number>] [--ip-address=<hostname or ip address>]

Automated Start-up and Shutdown

For Unix systems, the start-up and shutdown configurations apply that are executed by root, e.g. in /etc/init.d or corresponding locations and by use of systemd.

  • Consider use of the JS7_CONTROLLER_USER environment variable 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 file.

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 start-up and shutdown.
