geoip

Note, this documentation is also available in docstrings in the geo module.

Additional changes have been made in univ_drill to ensure that user_country is stored in Logs, if that setting is available in the session. This module handles getting the country code data into the session, and requires the use of a C library, GeoIP, and its relevant data files. Compilation is easy.

Installation

Table alterations for univ_drill.log

See geo/sql_changes.sql but be careful on production servers.

Install geoip C library

The C library is required for the geodjango GeoIP object to be able to perform lookups, and what we need out of this is the path of libGeoIP.so

    wget http://www.maxmind.com/download/geoip/api/c/GeoIP.tar.gz
    tar zxvf GeoIP.dat.gz
    cd into directory
    mkdir /home/univ_oahpa/univ_oahpa/geo/geoip
    ./configure --prefix=/home/univ_oahpa/univ_oahpa/geo/geoip
    make
    make install

Then find the path to that file, which should be:

	/home/univ_oahpa/univ_oahpa/geo/geoip/lib/libGeoIP.so

fetch data files

Here we need two .dat files.

    wget http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
    wget http://www.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
    
    gzip -d GeoLiteCity.dat.gz
    gzip -d GeoIP.dat.gz
    
    cp *.dat /home/univ_oahpa/univ_oahpa/geo/data/

settings.py

Include the following settings in settings.py, change the directories if you have installed them to another path.

	GEOIP_PATH = '/home/univ_oahpa/univ_oahpa/geo/data/'
	GEOIP_LIBRARY_PATH = '/home/univ_oahpa/univ_oahpa/geo/geoip/lib/libGeoIP.so'
	GEOIP_COUNTRY = 'GeoIP.dat'
	GEOIP_CITY = 'GeoLiteCity.dat'

Add the context processor to add country to user session info

	"univ_oahpa.geo.resolver.session_country"

Potential problems

Check that nginx is passing this in the fastcgi configuration, if not, add

	fastcgi_param REMOTE_ADDR $remote_addr;

Nginx proxy definitions need to have the following:

	proxy_set_header   X-Real-IP        $remote_addr;
	proxy_set_header   X-Forwarded-For  $remote_addr;

Make sure to use a separate header
