Django, Virtualenv, nginx + uwsgi import module wsgi error

Question

I am trying to set up a django project on an intermediate server with nginx, virtualenv and uwsgi, but I keep getting the import module wsgi error.

If theres a community, I can find the answer here ... Thank you all in advance.

These are my configuration files:

uwsgi.py in my django project:

import os import sys import site site.addsitedir(os.path.join(os.environ['WORKON_HOME'],'project/lib/python2.6/site-packages')) sys.path.append(os.path.abspath(os.path.dirname(__file__))) sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../../')) sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../')) os.environ['DJANGO_SETTINGS_MODULE'] = 'project.configs.staging.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() 

Nginx configuration

 # nginx configuration for project.maumercado.com server { server_name project.maumercado.com; access_log /home/ubuntu/logs/project/nginx/access.log; error_log /home/ubuntu/logs/project/nginx/error.log; location / { uwsgi_pass unix:/tmp/uwsgi.sock; include /etc/nginx/uwsgi_params; } location /static { root /home/ubuntu/django-projects/project/project/media; } location /media { root /home/ubuntu/django-projects/project/project/media; } } 

and, my uwsgi.conf

 # file: /etc/init/uwsgi.conf description "uWSGI starter" start on (local-filesystems and runlevel [2345]) stop on runlevel [016] respawn # home - is the path to our virtualenv directory # pythonpath - the path to our django application # module - the wsgi handler python script exec /home/ubuntu/ve/project/bin/uwsgi \ --uid www-data \ --pythonpath /home/ubuntu/django-projects/project/project/configs/staging/ \ --socket /tmp/uwsgi.sock \ --chmod-socket \ --module wsgi \ --logdate \ --optimize 2 \ --processes 2 \ --master \ --logto /home/ubuntu/logs/project/uwsgi.log 

Nginx logs contain nothing but 500 in access.log, therefore herw uwsgi.log:

I don’t know if anything related to my project has anything to do with it, but in any case the control file is used, which I use to redirect django utilities:

manage.sh

 #!/bin/bash python ./project/configs/${DEPLOYMENT_TARGET:="common"}/manage.py $* 

and just in case, as I created the django project:

 project |-manage.sh -> this fellow is redirected to settings.py (production, common or staging) |-requirements.txt |-README |-dashbard.py |-project.sqlite |- project/ |- apps |- accounts |-other internal apps |- configs |- common -> for local development |-settings.py |-manage.py |-urls |-staging |-manage.py |-settings.py |-wsgi.py |-logging.conf |-production |-manage.py |-settings.py |-wsgi.py |-logging.conf |-media |-templates

I updated wsgi.py to look like this:

 import os import sys import site site.addsitedir(os.path.join('/home/ubuntu/ve','project/lib/python2.6/site-packages')) sys.path.append(os.path.abspath(os.path.dirname(__file__))) sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../../')) sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../')) os.environ['DJANGO_SETTINGS_MODULE'] = 'project.configs.staging.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() 

Now the uwsgi.conf file looks like this:

 # file: /etc/init/uwsgi.conf description "uWSGI starter" start on (local-filesystems and runlevel [2345]) stop on runlevel [016] respawn # home - is the path to our virtualenv directory # pythonpath - the path to our django application # module - the wsgi handler python script exec /home/ubuntu/ve/project/bin/uwsgi \ --uid ubuntu \ --pythonpath /home/ubuntu/django-projects/project/project/configs/staging \ -H /home/ubuntu/ve/project \ --socket /tmp/uwsgi.sock \ --chmod-socket 644 \ --module wsgi \ --logdate \ --optimize 2 \ --processes 2 \ --master \ --logto /home/ubuntu/logs/project/uwsgi.log 

And my available nginx file looks like this:

 # file: /etc/nginx/sites-available/yourdomain.com # nginx configuration for project.maumercado.com server { listen 80; charset utf-8; server_name project.maumercado.com; access_log /home/ubuntu/logs/project/nginx/access.log; error_log /home/ubuntu/logs/project/nginx/error.log; location ^~ /cache/ { root /home/ubuntu/django-projects/project/project/media; expires max; } location / { uwsgi_pass unix:/tmp/uwsgi.sock; include /etc/nginx/uwsgi_params; } } 

And now it works fine, I had some style problems due to the fact that some strange characters were used in the css files.

Now I would like to know what should I do when I need to run more projects on one server using uwsgi?

be sure to add the directory containing the wsgi.py file in pythonpath (you can specify an unlimited sequence of pythonpath directives)
