A bit of exercising with python flask (based on http://flask.pocoo.org/docs/0.12/quickstart/)
We are using pipenv which seem to be the nicest thing for python in a while...
sudo apt install python3-pip python3-dev
pip install pipenv
Install virtual environment in the folder (if you do not create .venv the development setup will work but uwsgi/nginx setup won't):
mkdir .venv
pipenv install
pipenv shell
python mixflask/run.py
Make sure you have nginx, and python3 tools installed. The following instructions are for an debian-like system
Clone the files into a convenient location:
mkdir /www
sudo chown user www
git clone https://github.com/mixmixmix/funwithflask.git
Create place for uwsgi logs:
sudo mkdir /var/log/uwsgi
Make sure correct ownership is setup if running from a user account:
sudo chown -R user:user /var/log/uwsgi
(note: I assume that you clone this repo in /www/funwithflask as the services (/setup/mixflask.service) requires absolute paths.)
One change you might need to do is to change server_name in nginx config file /setup/mixflask. Then following:
sudo cp setup/mixflask.service /etc/systemd/system/
sudo systemctl start mixflask.service
sudo systemctl enable mixflask.service
sudo systemctl status mixflask.service
sudo cp setup/mixflask /etc/nginx/sites-available/mixflask
sudo rm /etc/nginx/sites-enabled/mixflask
sudo ln -s /etc/nginx/sites-available/mixflask /etc/nginx/sites-enabled/
sudo systemctl restart nginx.service
To apply changes in flask:
sudo systemctl restart mixflask.service
However to get logs of the system process (if it fails before starting uwsgi for instance) run
journalctl -u mixflask.service and if it fails later in nginx sudo cat /var/log/nginx/error.log)
