Module: mod_geoip

|

.. contents:: Table of Contents
|
||
Requirements
|
||
============
|
||
:Packages: GeoIP C API & Library (http://www.maxmind.com/download/geoip/api/c/)
|
||
Overview
|
||
========
|
||
mod_geoip is a module for fast ip/location lookups. It uses MaxMind GeoIP /
|
||
GeoCity databases.
|
||
If the ip was found in the database the module sets the appropriate
|
||
environments variables to the request, thus making other modules/fcgi be
|
||
informed.
|
||
.. note::
|
||
Currently only country/city databases are supported because they have a free
|
||
version that i can test.
|
||
Configuration Options
|
||
========================
|
||
mod_geoip uses two configuration options.
|
||
1) geoip.db-filename = <path to the geoip or geocity database>
|
||
2) geoip.memory-cache = <enable|disable> : default disabled
|
||
if enabled, mod_geoip will load the database binary file to
|
||
memory for very fast lookups. the only penalty is memory usage.
|
||
.. note::
|
||
mod_geoip will determine the database type automatically so if you enter
|
||
GeoCity databse path it will load GeoCity Env.
|
||
Environment
|
||
===========
|
||
Every database sets it's own ENV:
|
||
GeoIP (Country):
|
||
----------------
|
||
::
|
||
GEOIP_COUNTRY_CODE
|
||
GEOIP_COUNTRY_CODE3
|
||
GEOIP_COUNTRY_NAME
|
||
GeoCity:
|
||
--------
|
||
::
|
||
GEOIP_COUNTRY_CODE
|
||
GEOIP_COUNTRY_CODE3
|
||
GEOIP_COUNTRY_NAME
|
||
GEOIP_CITY_NAME
|
||
GEOIP_CITY_POSTAL_CODE
|
||
GEOIP_CITY_LATITUDE
|
||
GEOIP_CITY_LONG_LATITUDE
|
||
GEOIP_CITY_DMA_CODE
|
||
GEOIP_CITY_AREA_CODE
|
||
Examples
|
||
========
|
||
mod_geoip + php
|
||
---------------
|
||
when using fastcgi (not only php) you can access mod_geoip env and do as you
|
||
please. this example just prints all mod_geoip envs to the client, html.
|
||
Config-file ::
|
||
geoip.db-filename = "/your-geoip-db-path/GeoCityLite.dat"
|
||
geoip.memory-cache = "enable"
|
||
index.php ::
|
||
<?php
|
||
$country_code = $_SERVER['GEOIP_COUNTRY_CODE'];
|
||
$country_code3 = $_SERVER['GEOIP_COUNTRY_CODE3'];
|
||
$country_name = $_SERVER['GEOIP_COUNTRY_NAME'];
|
||
$city_region = $_SERVER['GEOIP_CITY_REGION'];
|
||
$city_name = $_SERVER['GEOIP_CITY_NAME'];
|
||
$city_postal_code = $_SERVER['GEOIP_CITY_POSTAL_CODE'];
|
||
$city_latitude = $_SERVER['GEOIP_CITY_LATITUDE'];
|
||
$city_long_latitude = $_SERVER['GEOIP_CITY_LONG_LATITUDE'];
|
||
$city_dma_code = $_SERVER['GEOIP_CITY_DMA_CODE'];
|
||
$city_area_code = $_SERVER['GEOIP_CITY_AREA_CODE'];
|
||
echo "<html>\n<body>\n\t<br>\n";
|
||
echo 'Country Code: ' . $country_code . '<br>';
|
||
echo 'Country Code 3: ' . $country_code3 . '<br>';
|
||
echo 'Country Name: ' . $country_name . '<br>';
|
||
echo '<br>';
|
||
echo 'City Region: ' . $city_region . '<br>';
|
||
echo 'City Name: ' . $city_name . '<br>';
|
||
echo 'City Postal Code: ' . $city_postal_code . '<br>';
|
||
echo 'City Latitude: ' . $city_latitude . '<br>';
|
||
echo 'City Long Latitude: ' . $city_long_latitude . '<br>';
|
||
echo 'City DMA Code: ' . $city_dma_code . '<br>';
|
||
echo 'City Area Code: ' . $city_area_code . '<br>';
|
||
echo "</html>\n</body>";
|
||
?>
|
||
country based redirect
|
||
----------------------
|
||
Config-file ::
|
||
$HTTP["host"] =~ "www.domain.com" {
|
||
url.rewrite = ( "" => "/redirect.php")
|
||
}
|
||
redirect.php ::
|
||
<?php
|
||
$country_code = $_SERVER['GEOIP_COUNTRY_CODE'];
|
||
header ('Location: http://' . $country_code . '.domain.com/');
|
||
?>
|
||
.. note::
|
||
Currently it is not possible to redirect based on mod_geoip directly in
|
||
lighttpd config file. But i believe with the relase of lighttpd mod_magnet
|
||
it would be. (mod_magnet will be available in lighttpd 1.4.12+)

* Name:

* mod_geoip.c
|

|
||
* Description:
|
||
* GeoIP module (plugin) for lighttpd.
|
||
* the module loads a geoip database of type "country" or "city" and
|
||
* sets new ENV vars based on ip record lookups.
|
||
*
|
||
* country db env's:
|
||
* GEOIP_COUNTRY_CODE
|
||
* GEOIP_COUNTRY_CODE3
|
||
* GEOIP_COUNTRY_NAME
|
||
*
|
||
* city db env's:
|
||
* GEOIP_COUNTRY_CODE
|
||
* GEOIP_COUNTRY_CODE3
|
||
* GEOIP_COUNTRY_NAME
|
||
* GEOIP_CITY_NAME
|
||
* GEOIP_CITY_POSTAL_CODE
|
||
* GEOIP_CITY_LATITUDE
|
||
* GEOIP_CITY_LONG_LATITUDE
|
||
* GEOIP_CITY_DMA_CODE
|
||
* GEOIP_CITY_AREA_CODE
|
||
*
|
||
* Usage (configuration options):
|
||
* geoip.db-filename = <path to the geoip or geocity database>
|
||
* geoip.memory-cache = <enable|disable> : default disabled
|
||
* if enabled, mod_geoip will load the database binary file to
|
||
* memory for very fast lookups. the only penalty is memory usage.
