在uwsgi或gunicorn无法正常工作的Nginx上部署Django应用

Question

I am trying to deploy a django application on ubuntu with nginx server. I try to use both methods by gunicorn and uwsgi but still not workong. I go through a lot of tutorial. Main issue may be that my django app is not on virtual env. It is directly on my server. Please help me in figuring out.

Django app is working stand alone on 8000 port. and ngnix is also running. Gunicorn and uwsgi is also installed properly. uwsgi gives this error while running:

uwsgi --ini uwsgi.ini

Nginx is giving 404 error. Please help me in deployment.

I also follow this question from [1]: Django app deployment on nGINX

Answer 1

Well also the error might be very clearly stated at the end of the error log

Check that you don't make non-lazy gettext calls at import time

If you have translation calls in your code make sure they are lazy calls , lazy calls are not evaluated until they're needed, and that's usually on the front end or when writing the values to some output or a log. In some rare cases you will have to use non-lazy calls, but make sure they're not being executed before all the apps are ready and Django is ready, so especially in your settings.py file.

Also I second @dizballanze, DO NOT RUN uWSGI AS ROOT.

Answer 2

I think the problem is described in following line of uwsgi output:

!!! no internal routing support, rebuild with pcre support !!!

Try to install pcre:

sudo apt-get install libpcre3 libpcre3-dev

and when reinstall uwsgi:

pip uninstall uwsgi
pip install uwsgi

PS You are really should not run the application as root user.

Answer 3

I think this project can help you alot. it deploys to EC2 but you can read the source code to help you with your deployment. Its easy and does everything you ask for.
