Python on Nginx

The instruction given on http://wiki.nginx.org/PythonFlup is to install
nginx supporting python. But I have a working Nginx with php-fpm
supporting PHP. Now I want to add support of python too. Thus, my config
is slightly different. I successfully installed Python 2.6, Django and
python-flup. Everything went good, but python does not work on web (when
visiting test.py, it downloads the file instead of running the script).

How should modify the nginx config to support python?

nginx doesn’t know (or care) that you are using php or python or
anything
else. All it knows is how you have configured different location{}
blocks.

Each request is handled by one location, so you must make sure that you
have the right configuration in the location that your request matches.

If you are currently using php-fpm, you probably have something like

location [something that matches urls that should be handled by php] {
fastcgi_pass [your php-fastcgi server];
}

So now that you are adding a separate fastcgi server that is associated
with python, you’ll want to add a new location block like

location [something that matches urls that should be handled by python]
{
fastcgi_pass [your python-fastcgi server];
}

The details depend on what you’re trying to do. The documentation on
“location”, or the debug log, should show you which location is being
used for each request – if it’s not the right one, you’ll need to
adjust the config.

Good luck with it,

My server is as
server { server_name .domain.com;
listen 80;
root /home/domain.com;
index index.html index.php;
location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /opt/nginx/conf/fastcgi_params;
}
}

You mean to add another location as
location ~ .py$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.py;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /opt/nginx/conf/fastcgi_params;
}

This is what I’m using with Debian Squeeze & fcgiwrap installed, not
just
for python.

location ~ (.cgi|.py|.sh|.pl|.lua)$ {
gzip off;
root /var/www/$server_name;
autoindex on;
fastcgi_pass unix:/var/run/fcgiwrap.socket;
include /etc/nginx/fastcgi_params;
fastcgi_param DOCUMENT_ROOT /var/www/$server_name;
fastcgi_param SCRIPT_FILENAME
/var/www/$server_name$fastcgi_script_name;
}

Also I chmod +x the python scripts and add
#! /usr/bin/python
to the beginning of the python script.
Change the path if python is located elsewhere.

If all of your python urls end in .py, yes.

Although you probably don’t want 127.0.0.1:9000, since that’s
your php-fastcgi server. You’ll want whatever your python-fastcgi
server address is: probably 127.0.0.1:8080, if you followed
http://wiki.nginx.org/PythonFlup

BTW, I know that some people prefer to use uWSGI server for python.

I prefer frameworks like gunicorn that use plain HTTP.

fcgiwrap is a completely different beast and doesn’t apply one whit to
running Django. You need to follow the directions you linked to at
http://wiki.nginx.org/PythonFlup

  1. Set up a location for your PHP applications
  2. Set up a different location for your Django application and use the
    directions from the wiki for getting it configured.

uWSGI suggests using the uwsgi protocol to improve performance and to
add
some specific feature, but you can run it in http, fastcgi and zeromq
mode.

There’s lots of articles on setting up Django + uwsgi + Nginx out there.

Of course uWSGI suggest using uwsgi :wink:

HTTP is easier to debug and do other “normal things” with it. I just
use the normal nginx proxy.
