I just recently grabbed a hosting setup on VPSLink.com and wanted to get Django up and running. I'd heard good things about nginx, but had never set it up or configured it before, so I figured I'd give it a try. There were a few little bumps I ran into, but in the end the setup worked pretty well so I wanted to share my setup and configuration experience with everyone here.

This setup is running Ubuntu Hardy 8.04 as a xen instance on VPSLink, this walks through starting everything up from scratch, but assumes you are running as root (type `su` to switch to the root user)

The first thing I had to do was install python:
{{{
aptitude install python
}}}

Next, I needed Django, which I got the latest SVN release (due to a ManyToMany bug I saw in the past, I'm sticking to a release I didn't have trouble with):
{{{
aptitude install subversion
cd /
mkdir django
cd django
svn co http://code.djangoproject.com/svn/django/trunk/
cd trunk
python setup.py install
}}}

Next, to run Django through fastcgi, we need python-flup:
{{{
aptitude install python-flup
}}}

Let's start a sample project just to make things easy:
(Note: for some reason, the PYTHONPATH and PATH variables, although they included the django bin directory, still couldn't find django-admin.py, so I included the full path)
{{{
cd /
mkdir projects
cd projects/
python /usr/lib/python2.5/site-packages/django/bin/django-admin.py startproject sample_project
}}}

Also, create a media directory:
{{{
cd /
mkdir media
}}}

Let's start up the fastcgi setup:
(Note: I didn't need any extra stuff on my pythonpath, but if you do, just add --pythonpath=/path/to/add)
(Note: Nothing should print here)
{{{
cd /projects/sample_project/
python manage.py runfcgi host=127.0.0.1 port=8080 --settings=settings
}}}


Now let's setup Nginx:

First, create a user for nginx to run as, and then remove a password from it so no one can log in as the user:
{{{
useradd nginx
passwd -d nginx
}}}

Let's install nginx from aptitude:
{{{
aptitude install nginx
}}}

Next, we need to change the configuration (and back up the default one just in case):
{{{
cd /etc/nginx/
mv nginx.conf nginx-backup.conf
touch nginx.conf
}}}

Now we need to put some new stuff into the default nginx configuration, here is the template I used:
{{{
user  nginx nginx;

worker_processes  2;

error_log /var/log/nginx/error_log info;

events {
	worker_connections  1024;
	use epoll;
}

http {
	include		/etc/nginx/mime.types;
	default_type	application/octet-stream;

	log_format main
		'$remote_addr - $remote_user [$time_local] '
        	'"$request" $status $bytes_sent '
		'"$http_referer" "$http_user_agent" '
		'"$gzip_ratio"';

	client_header_timeout	10m;
	client_body_timeout	10m;
	send_timeout		10m;

	connection_pool_size		256;
	client_header_buffer_size	1k;
	large_client_header_buffers	4 2k;
	request_pool_size		4k;

	gzip on;
	gzip_min_length	1100;
	gzip_buffers	4 8k;
	gzip_types	text/plain;

	output_buffers	1 32k;
	postpone_output	1460;

	sendfile	on;
	tcp_nopush	on;
	tcp_nodelay	on;

	keepalive_timeout	75 20;

	ignore_invalid_headers	on;
	index index.html;

	server {
		listen 80;
		server_name localhost;
		location /site_media  {
			root /media/; # Notice this is the /media folder that we create above
		}
		location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|mov) {
			access_log   off;
			expires      30d; 
		}
		location / {
			# host and port to fastcgi server
			fastcgi_pass 127.0.0.1:8080;
			fastcgi_param PATH_INFO $fastcgi_script_name;
			fastcgi_param REQUEST_METHOD $request_method;
			fastcgi_param QUERY_STRING $query_string;
			fastcgi_param CONTENT_TYPE $content_type;
			fastcgi_param CONTENT_LENGTH $content_length;
			fastcgi_pass_header Authorization;
			fastcgi_intercept_errors off;
			fastcgi_param REMOTE_ADDR $remote_addr;
			}
		access_log	/var/log/nginx/localhost.access_log main;
		error_log	/var/log/nginx/localhost.error_log;
	}
}
}}}

Now all we need to do is start up nginx:
{{{
/etc/init.d/nginx start
}}}
