nginx-gridfs howto

As the nightly build will fail with nginx-gridfs, we have to compile mongodb 
from scratch and use the fresh libmongoclient.a version.

1) Install neccessary dependencies for Ubuntu

apt-get -y install tcsh git-core scons g++
apt-get -y install libpcre++-dev libboost-dev libreadline-dev libmozjs-dev

2) Get the source from github and compile it (Note we do not need to run scons 
install, because we only need the libmongoclient.a)

cd /home/user
git clone git://github.com/mongodb/mongo.git
cd mongo
scons all

3) Next set the required environment variables for the nginx-gridfs module

export MONGO_INCLUDE_PATH=/home/user/mongo/
export LIBMONGOCLIENT=/home/user/mongo/libmongoclient.a
export BOOST_INCLUDE_PATH=/usr/include/boost/
export LIBBOOST_THREAD=/usr/lib/libboost_thread-gcc42-mt-1_34_1.so.1.34.1
export LIBBOOST_FILESYSTEM=/usr/lib/libboost_filesystem-gcc42-mt-1_34_1.so.1.34.1

4) Get Nginx and nginx-gridfs running

wget http://sysoev.ru/nginx/nginx-0.8.8.tar.gz
tar -xzf nginx*.tar.gz
cd nginx*
./configure --add-module=/home/users/nginx-gridfs --prefix=/usr/local/nginx
make
make install

5) Enjoy the performance
