Windows

  1. Download the KA Lite Windows installer.
  2. Double-click the downloaded .exe file, and the wizard window will appear to guide you through the process of installing KA Lite on your server.

Upgrading KA Lite over an existing installation is easy – just run the installer and follow the prompts! You don’t need to uninstall your old KA Lite installation first.

Mac/OSX

  1. Download the KA Lite OSX installer.

  2. After the download is complete, double click the .dmg file.

  3. On the .dmg window, drag the “KA-Lite Monitor” app into the “Applications” folder.

    Note

    To upgrade an existing KA Lite installation, download the new installer and then drag it over to the “Applications” folder to replace the existing “KA-Lite-Monitor” application. Give confirmation to overwrite the existing app. Then proceed from this step as usual.

  4. Launch “KA-Lite Monitor” from your ‘Applications’ folder.

  5. On first load, it will check your current environment and show the Preferences dialog.

  6. Input your preferred admin username and password.

  7. Click on the Apply button.

  8. You will be prompted that initial setup will take a few minutes, click the “OK” button and wait for the notification that KA-Lite has been setup and can now be started.

  9. Click on the KA-Lite logo icon on the Status Menu Bar and select the “Start KA-Lite” menu option.

  10. When prompted that KA-Lite has been started, click on the logo icon again and select “Open in Browser” menu option - this should launch KA-Lite on your preferred web browser.

  11. Login using the administrator account you have specified during setup.

Linux

Main method: Ubuntu/Debian .deb

Download the latest .deb manually from our server. After that, you can install the .deb file like this:

sudo dpkg -i FILENAME.deb

FILENAME should be replaced with the name of the file you downloaded. The file may be named as if it was intended for Ubuntu but works just as well for any other Debian-based systems like Debian, Raspberry Pi, Linux Mint etc.

You will be prompted to enter some configuration information. You should read the on-screen instructions carefully, but some explanation is included here:

1. You will asked to choose to run KA Lite on boot or not. We recommend choosing yes, as it simplifies data management. If you choose no, you must manually start KA lite every time. Note that running KA Lite as different users creates different sets of data files, so it’s recommended that you run KA Lite as the same user every time.

2. If you chose to start on boot in the previous step, you will be prompted to choose the owner for the KA Lite server process. Generally the default value is ok.

  1. You will be asked to review your choices, and finally KA Lite will start automatically when installation is complete.

Tip

If you want to receive automatic updates from online sources, you can also use Debian/Ubuntu: Subscribe to updates through a PPA.

Raspberry Pi

For a Raspberry Pi running a Debian system, you can install the special Debian package ka-lite-raspberry-pi.

It can be installed by downloading the latest .deb on the Pi and installing it:

# Install dependencies
sudo apt-get install python-m2crypto python-pkg-resources nginx python-psutil
# Fetch the latest .deb
sudo wget https://learningequality.org/r/deb-pi-installer-0-15
# Install the .deb
sudo dpkg -i ka-lite-raspberry-pi*.deb

You can also add the PPA, see Debian/Ubuntu: Subscribe to updates through a PPA, and then run sudo apt-get install ka-lite-raspberry-pi.

After installing, you can setup a Wifi hotspot using this guide: Raspberry Pi Wi-Fi

Other options

KA Lite is available for all platforms (e.g. non-Debian compatible platforms) through PyPi. See Generic installation (pip install).

Configuration after installation or update

Every time you install or update KA Lite, you must run kalite manage setup command again to setup the database and download assessment items (video descriptions, exercises etc.).

Uninstalling

Windows

  1. Uninstall KA Lite from the Control Panel.
  2. In Windows XP, double-click the “Add or Remove Programs” icon, then choose KA Lite.
  3. In later version of Windows, click the “Programs and Features” icon, then choose KA Lite.

Mac OSX

  1. Launch KA-Lite Monitor from your Applications folder.
  2. Click on Preferences in the menu option.
  3. Click the Reset App from The Advanced
  4. You will be prompted that “this will reset app. Are you sure?”, just click on OK button.
  5. Another dialog will appear asking your Password just click on Cancel button.
  6. Quit the KA-Lite Monitor app.
  7. Move KA-Lite Monitor app to Trash.

Linux: Debian/Ubuntu

Option 1: Open up Ubuntu Software Center and locate the KA Lite package. Press Remove.

Option 2: Use apt-get remove <name of package>. You have to know which package you installed, typically this is ka-lite or ka-lite-bundle.

Installed with pip

You can remove KA Lite (when installed from pip or source distribution) with pip uninstall ka-lite or pip uninstall ka-lite-static (static version).

Removing user data

Some data (like videos and language packs) are downloaded into a location that depends on the user running the KA Lite server. Removing that directory can potentially reclaim lots of hard drive space.

On Windows, the HOME and USERPROFILE registry values will be used if set, otherwise the combination %HOMEDRIVE%%HOMEPATH% will be used. You can check these values from the command prompt using the commands echo %HOME%, echo $USERPROFILE%, etc. Within that directory, the data is stored in the .kalite subdirectory. On most versions of Windows, this is C:\Users\YourUsername\.kalite\.

On Linux, OSX, and other Unix-like systems, downloaded videos and database files are in ~/.kalite.
