gunicorn not starting workers

阅读更多关于 gunicorn not starting workers

When i run this command [jenia@arch app]../bin/gunicorn zones.wsgi:application --bind localht:8000 The gunicorn server runs at localhost:8000. It doesnt return anything to the console as I assume it should. Just runs silently. When I run my script in bin/gunicorn_start the server still runs silently and features odd behaviour. If I input an address that django can't resolve it gives me internal server error and that's it. no stack trace no nothing. This is the bin/gunicorn_start script: #!/bin/bash NAME="hello_app" # Name of the application DJANGODIR=/srv/http/proj05/app # Django project

Using python's Multiprocessing makes response hang on gunicorn

阅读更多关于 Using python's Multiprocessing makes response hang on gunicorn

First I will admit that there are a few to many keywords in that title, but I am indeed really trying to capture the problem in the correct manner. The issue here is that I can not seem to be able to correctly create a sub process using the python multiprocessing module without it causing the webpage response to hang. I have tried a few recent versions of gunicorn and the problem persists. Interestingly, the problem never was an issue on ubuntu server, but now moving the application to rhel6.5 this issue has presented itself. Here is the workflow: -route is hit -form is submitted which hits

Async worker on gunicorn seems blocking

阅读更多关于 Async worker on gunicorn seems blocking

问题 I am using a Flask app with the gunicorn server and the gevent worker class, which according to the gunicorn documentation is an asynchronous worker. However, when I launch gunicorn with a single worker and try to make a long request (I added sleep(10) in the route function, but in reality this also happens when processing large uploads), I can't make any request until the previous one is finished. It behaves as is it is a synchronous worker, one request at a time. Is this the normal behavior

How to use Django logging with gunicorn

阅读更多关于 How to use Django logging with gunicorn

I have a Django 1.6 site running with gunicorn, managed by supervisor. During tests and runserver I have logging on the console, but with gunicorn the statements don't show up anywhere (not even ERROR level logs). They should be in /var/log/supervisor/foo-stderr---supervisor-51QcIl.log but they're not. I have celery running on a different machine using supervisor and its debug statements show up fine in its supervisor error file. Edit: Running gunicorn in the foreground shows that none of my error messages are being logged to stderr like they are when running manage.py. This is definitely a

阅读更多关于 How do I run a flask app in gunicorn if I used the application factory pattern?

问题 I wrote a flask app using the application factory pattern. That means it doesn't create an app instance automatically when you import it. You have to call create_app for that. Now how do I run it in gunicorn? 回答1: Create a file wsgi.py under your project with the following contents, then point Gunicorn at it. from my_project import create_app app = create_app() gunicorn -w 4 my_project.wsgi:app # -w 4 specifies four worker processes Gunicorn allows specifying a function call like my_project

I have followed this tutorial: http://blog.wercker.com/2013/11/25/django-16-part3.html and I am just trying to make it work locally with Vagrant for now. I am not trying to use Wercker. After everything is installed, I try to access the website but I get a Bad Request (400) error every time. I do not know if that is due to a problem in nginx or in gunicorn. They both have a log entry so at least I know that the request goes all the way through gunicorn and is not stopped at the nginx level. Where is the problem located? Gunicorn? nginx? Here are the logs of gunicorn and nginx. I see that the
