Flask redirect(url_for) error with gunricorn + nginx

阅读更多关于 Flask redirect(url_for) error with gunricorn + nginx

问题 I am having a problem with the redirect(url_for) function in my flask app. Any redirect(url_for("index")) line redirects the application from domain.com/app to ip-addr/app , where the ip-addr is my own client machines ip, not the server's. This has gotten me very confused, and I don't know where exactly the issue occurs, as it only happens on the server and not on any local testing. Details: I am using the reverse proxy setup found here http://flask.pocoo.org/snippets/35/. My nginx config is

Flask app logger not working when running within gunicorn

问题 I'm trying to save application log messages from a very simple flask app in a log file. While this works flawlessly when I'm running the app with the embedded Flask server, it is not working at all when running within gUnicorn, basically, no application output is redirected neither the log file (the one specified in my Flask app) or to the STDOUT when running gunicorn. That said, this is my Flask app: @app.route('/') def index(): app.logger.debug('Into /!!!!') print 'Will this print?' return

How to get coverage data from a django app when running in gunicorn

阅读更多关于 How to get coverage data from a django app when running in gunicorn

问题 How do I get code coverage out of a Django project's view code (and code called by view code)? coverage gunicorn <params> does not show any lines being hit. 回答1: coverage gunicorn <params> does not work, because gunicorn creates worker processes, and the coverage module can't work across forks (basically, creation of new processes). You can use the coverage API, though, for example in the python module that contains your WSGI application: # wsgi_with_coverage.py import atexit import sys

Gunicorn logging from multiple workers

阅读更多关于 Gunicorn logging from multiple workers

问题 I have a flask app that runs in multiple gunicorn sync processes on a server and uses TimedRotatingFileHandler to log to a file from within the flask application in each worker. In retrospect this seems unsafe. Is there a standard way to accomplish this in python (at high volume) without writing my own socket based logging server or similar? How do other people accomplish this? We do use syslog to aggregate across servers to a logging server already but I'd ideally like to persist the log on

gunicorn slower than flask development server

阅读更多关于 gunicorn slower than flask development server

问题 My Flask application has a simple feature with a textarea where you input HTML and clicking on a button will strip all the HTML tags and return the text inside the HTML into another textarea, say Text. When I run my application with: app.run(debug=True, host='0.0.0.0', port='8000') it works very fast and smooth. But when I run it with gunicorn like this: gunicorn -w 3 -b 0.0.0.0:8000 --log-file=- myapp.app:app after I click the button 'HtmlToText' it takes too much time to return the text

To serve static files I am running nginx as a reverse proxy. /etc/nginx/nginx.conf is configured to forward requests as follows: server { location /static/ { alias /data/www/; } # Proxying the connections location / { proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_redirect off; proxy_pass http://0.0.0.0:8000; } } and my docker
