nginx and django without virtualenv

[Paul Greenberg]

All,

I was running django with Apache and mod_wsgi for a while. Now, I am planning to run django without virtualenv. Although, it seems virtualenv might help.

http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html

Any pointers? Performance issues?

Personally, in my `manage.py and `wsgi.py, I have the line:

import site

site.addsitedir('/path/to/virtenv/lib/python2.7/site-packages')

Actually, truthfully, I've merged wsgi.py and manage.py into one manage.py)

#!/usr/bin/env python
import os
import site
import sys
sys.dont_write_bytecode = True  # don't write .pyc files
sys.path.append(os.path.dirname(__file__))
site.addsitedir('/path/to/virtenv/lib/python2.7/site-packages')
os.environ['DJANGO_SETTINGS_MODULE'] = 'demo.settings'


if __name__ == '__main__':  # command line
    from django.core.management import execute_from_command_line
    execute_from_command_line(sys.argv)
else:  # wsgi
    from django.core.wsgi import get_wsgi_application
    application = get_wsgi_application()

Performance *should* be identical.

All that virtualenv does (from the point of view of the executing python program) is to change how sys.prefix and sys.exec_prefix are set, and thus, how sys.path is calculated.

But with a vanilla sys.path, you need to be sure that django, your other dependencies, and your project are all still found.  (Installing django in a virtualenv does *NOT* also install it in the main python (actually, it's the python that mod_wsgi is linked against that counts).

Collin,

I will be running it with p3.4.

How is the performance of it?

Actually, that's a good point. I always use the same python version that's linked with mod_wsgi. I don't use a virtualenv to use a different python version.

[Paul Greenberg]

Bill,

I see. However, I wanted to try uwsgi instead of mod_wsgi. I will be using nginx, not Apache.

Though if he's moving to nginx, thus not mod_wsgi, I guess it doesn't matter what mod_wsgi is linked against.

Right.  I thought of that later.

But virtualenv or not is still just a different sys.path, and you still have to have your stuff installed in the correct python.
