This code is designed to allow the Raspberry Pi in an OpenSO2 scanner to act as a server, displaying the results for any user on the network.
Install vertualenv if it not already in the base environment:
pip3 install virtualenv
Clone the repository and enter:
git clone https://github.com/benjaminesse/ScanPiServer.git
cd ScanPiServer
Create the virtual environment and activate:
python3 -m venv venv
. venv/bin/activate
Install the dependencies:
pip3 install numpy pandas plotly Flask gunicorn PyYAML
To test the server run:
cd /home/pi/ScanPiServer/
. venv/bin/activate
gunicorn -w 4 -b 0.0.0.0:4000 app:app --log-file=gunicorn.log
Then open [ScanPi IP Address]:4000 in a browser on the same network as the Raspberry Pi, you should see the station landing page. If not, check the gunicorn.log file.
To automatically turn on the server on boot open crontab using:
crontab -e
You may have to select a text editor the first time, I would recommend nano. Then add the following line to the bottom:
@reboot cd /home/pi/ScanPiServer/ && . venv/bin/activate && gunicorn -w 4 -b 0.0.0.0:4000 app:app -D --log-file=gunicorn.log
Then reboot the Raspberry Pi using sudo reboot. When the Pi reboots the server should be available on the network at [ScanPi IP Address]:4000.
