cd /opt/
wget http://projects.unbit.it/downloads/uwsgi-0.9.8.2.tar.gz
tar -zxvf uwsgi-0.9.8.2.tar.gz
mv uwsgi-0.9.8.2/ uwsgi/

Install nginx from ppa

Ubuntu PPA
You can get the latest stable version of Nginx from the Nginx PPA on Launchpad:

You will need to have root privileges to perform the following commands.

For Ubuntu 10.04 and newer:

sudo -s
nginx=stable # use nginx=development for latest development version
add-apt-repository ppa:nginx/$nginx
apt-get update 
apt-get install nginx
If you get an error about add-apt-repository not existing, you will want to install python-software-properties.

Configure uWSGI

cd /opt/
wget -O init-deb.sh http://library.linode.com/assets/689-uwsgi-init-deb.sh
mv /opt/init-deb.sh /etc/init.d/uwsgi
chmod +x /etc/init.d/uwsgi

Create an /etc/default/uwsgi.ini file with below,
[uwsgi]
socket = 127.0.0.1:9001
master = true
processes = 4
chdir = /home/apgeorge/code/mangrove/src/datawinners
pythonpath = /home/apgeorge/code/mangrove/src
env = DJANGO_SETTINGS_MODULE=datawinners.settings
module = django.core.handlers.wsgi:WSGIHandler()
pidfile = /tmp/project-master.pid
vacuum = true
max-requests = 5000
daemonize = /var/log/uwsgi.log
home = /home/apgeorge/code/VEs/mangrove

Edit, etc/init.d/uwsgi file, modify below to,
#DAEMON_OPTS="-s 127.0.0.1:9001 -M 4 -t 30 -A 4 -p 4 -d /var/log/uwsgi.log --pythonpath $PYTHONPATH --module $MODULE"
DAEMON_OPTS="--ini /etc/default/uwsgi.ini"

/usr/sbin/update-rc.d -f uwsgi defaults
/etc/init.d/uwsgi start

Configure NGINX

Add the below to the /opt/nginx/conf/nginx.conf file under the server section.
location /media {
        root   /home/apgeorge/code/mangrove/src/datawinners/media/;
        }

        location / {
        include uwsgi_params;            
        uwsgi_pass   127.0.0.1:9001;
            index  index.html index.htm;
        }

/etc/init.d/nginx restart or /etc/init.d/nginx start
