Installing SQLstream StreamLab on Linux

SQLstream StreamLab is a browser-based application that lets you view and create visualizations of streaming data.

If you are running Guavus SQLstream in a Docker container, an Amazon Marketplace AMI, Microsoft Azure MI or other virtual machine >, Guavus StreamLab is installed alongside Guavus s-Server. If you are running Guavus SQLstream on Linux, you need to install StreamLab on its own.

You should install and run StreamLab after Installing SQLstream s-Server.

Installing StreamLab

You can install SQLstream StreamLab using an X-windows wizard. The easiest way to launch the installer is by initiating the installation file from the command line.

The StreamLab installer ships as a binary file - usually named SQLstream-StreamLab-2.3.0 (where X.Y.Z is the version number) that you acquired by downloading it from http://www.sqlstream.com/downloads.

You can also install StreamLab from the command line.

To install StreamLab:

  1. From a terminal prompt enter ./SQLstream-StreamLab-X.Y.Z-linux-x64.run, where X.Y.Z represent the release and version numbers, as in SQLstream-StreamLab-2.3.0.run. If the installer does not launch, make sure the file is executable by running chmod +x . The Welcome page appears, introducing the Setup Wizard.
  2. Click Forward. The License Agreement page of the installation wizard opens.
  3. If you are logged in as root, the default directory is /opt/sqlstream/2.3.0/, otherwise the default directory is /home//sqlstream/SQLstream/<VERSION>/ Confirm the directory, then click Forward. The Repository Directory page opens.
  4. Confirm the directory, then click Forward.
  5. Click Forward. The StreamLab Service/Daemon page opens. This page lets you setup StreamLab as a service that starts automatically at system startup.
  6. Choose whether or not to create the service and click Forward. The Ready to Install page opens.
  7. Click Forward to start the Installation.

Using Google Maps and OpenStreetMaps Tiles with StreamLab

To use maps, you need to obtain and install either a Google Maps or MapBox api key before maps can be used.

If you are using the the Pan and Zoom map visualization, StreamLab and s-Dashboard require a Google Maps API key.

To retrieve an API key, please visit the following link:

https://developers.google.com/maps/documentation/javascript/tutorial# api_key

Once you have a Google Maps API key, you need to restart StreamLab to incorporate it. To do so when launching StreamLab from the command line, use a -m flag, as in:

-m google:AGzaSyrDBVfuWtaa40S1pM8U-0YED3ONjvq6-7mFZ*

To do so when launching StreamLab using the 'Start Streamlab Server' icon, right-click on the desktop 'Start Streamlab Server' icon, select Properties, and add the -m option to the end of the command.

You can now use the Pan and Zoom map visualization with full functionality.

Using StreamLab with OpenStreetMaps

To use OpenStreetMaps tiles, you need a Mapbox id. To design a map, go to  

https://www.mapbox.com/

and sign up and design the map they want.

Each map has a map id. This gets used in the -m option preceded by 'mapbox:', as in:

-m mapbox:myserver.jeo4y40c

All StreamLab maps will use the same tile set. In order to use a different tile set, you need to restart StreamLab with a different Mapbox id.

Setting the Map Service in the Linux Environment

You can also set the map service in /etc/default/streamlabd, by setting STREAMLABMAPSERVICE to 'google:' or 'mapbox:'.

Installing StreamLab on the Command Line

You can also install in text mode, which does not display the graphical installation wizard. To do so, enter

sudo ./StreamLab-X.Y.Z-x64.run --mode text

where X.Y.Z represent the release and version numbers, as in SQLstream-StreamLab-2.3.0.run.

if you are logged in as a super user, you do not need to include "sudo".

The text-mode installer performs the same steps as the graphical one, but displays its prompts and messages in the console window. By default, the installer will run in graphical mode, GTK. If this is not possible, it will run in xwindow mode. If there is no graphical environment available it will fall back to text mode.
