# Run
|
|
|
|
## in Development
|
|
`export FLASK_APP=run.py`
|
|
`export FLASK_ENV=development`
|
|
`flask run`
|
|
|
|
**Using gunicorn:**
|
|
|
|
`gunicorn --env SCRIPT_NAME=/watermark -w 4 -b 127.0.0.1:5000 app:app --log-level debug`
|
|
* `-w` workers
|
|
* `-b` bind to address / unix socker
|
|
|
|
**And gunicorn with using unix sock:** (this how it should run in production)
|
|
` gunicorn --env SCRIPT_NAME=/watermark --workers 4 --bind unix:app.sock -m 007 app:app --log-level debug
|
|
|
|
## in Production with gunicorn and unix sockets
|
|
Based on https://medium.com/faun/deploy-flask-app-with-nginx-using-gunicorn-7fda4f50066a
|
|
|
|
### systemd service file
|
|
|
|
Add to /etc/systemd/system/watermarks.service
|
|
|
|
```
|
|
[Unit]
|
|
After=network.target
|
|
|
|
[Service]
|
|
User=psc
|
|
Group=www-data
|
|
WorkingDirectory=/var/www/TacticalApp
|
|
Environment="PATH=/var/www/TacticalApp/venv/bin"
|
|
ExecStart=/var/www/TacticalApp/venv/bin/gunicorn --env SCRIPT_NAME=/watermarks --workers 4 --bind unix:app.sock -m 007 app:app
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
## enable & start service file
|
|
`systemctl enable watermarks.service`
|
|
|
|
`systemctl start watermarks.service`
|
|
|
|
It is also a good idea to check the status of the service
|
|
`systemctl status watermarks.service`
|
|
|
|
## Nginx config
|
|
|
|
```
|
|
location / {
|
|
# if using gunicorn with app sock, use:
|
|
proxy_pass http://unix:/var/www/TacticalApp/app.sock;
|
|
# if using gunicord with port 5000, use:
|
|
proxy_pass http://127.0.0.1:5000;
|
|
}
|
|
```
|
|
|
|
## debug.
|
|
|
|
It might be helpful to enable gunicorn logging, while in development, to check what is going on,
|
|
by replacing in watermarks.service, the `ExecStart=` value with:
|
|
|
|
`ExecStart=/var/www/TacticalApp/venv/bin/gunicorn --log-level debug --error-logfile /var/www/TacticalApp/app.log --workers 4 --bind unix:app.sock -m 007 app:app`
|
|
|
|
And reloading the services
|
|
`systemctl daemon-reload`
|
|
|
|
`systemctl restart watermarks.service`
|
|
|
|
and the start following app.log:
|
|
`tail -f /var/www/TacticalApp/app.log`
|
|
|
|
But in the long run logging should be disabled
|

09.06.2020 Handling url path /watermarks
|
|
|
|
* gunicorn has to be started with argument `--env SCRIPT_NAME=/watermark` which defines its path:
|
|
`gunicorn --env SCRIPT_NAME=/watermark --workers 4 --bind unix:app.sock -m 007 app:app --log-level debug`
|
|
* allows for the following URLs
|
|
* http://127.0.0.1/watermark
|
|
* http://127.0.0.1/watermark/uploadbook
|
|
* http://127.0.0.1/watermark/about
|
|
|
|
* added page /test `watermark/test` for testing url_for() - correct
|
|
* made urls relative
|
|
* service file with `--env SCRIPT_NAME=/watermark` see above
|
|
*
|
|
gunicorn -w 4 -b :5000 app:app
