How to Start GN2 and GN3

This document describes in a short how we run GN2 and GN3 on the current production setup.

Note that we should replace this with a system container.

This details how GN2/GN3 production are currently started. It's probably a good idea to create a shell script for starting GN3 like we have for GN2 at some point, since currently environment variables are set manually.

GN3

GN2 depends on GN3 for REST services and libraries.

Environment

Set PATH/PYTHONPATH/GN2_PROFILE environment variables

Example:

export GN2_PROFILE=/home/zas1024/opt/gn-latest-20221206
export PATH=$GN2_PROFILE/bin:$PATH
export PYTHONPATH="$GN2_PROFILE/lib/python3.9/site-packages"

Start development on port 8081

Start GN3 from the relevant directory

env FLASK_DEBUG=1 FLASK_APP="main.py" CORS_ORIGINS="http://gn2-zach.genenetwork.org:*,https://gn2-zach.genenetwork.org:*,http://genenetwork.org:*,https://genenetwork.org:*" flask run --port=8081

GN3 has a settings.py file now. See the README.

Start production on port 8087

gn2@tux01:
cd ~/gn3_production/genenetwork3
gunicorn --bind 0.0.0.0:8087 --workers 8 --keep-alive  6000 --max-requests 10 --max-requests-jitter 5 --timeout 1200 wsgi:app

Note I had to comment out some oauth stuff on the latest.

GN2

1. Just run /home/gn2/production/run_production.sh
