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:

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"
|
||
|
|
|

|
||

$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'];

echo 'Country Code: ' . $country_code . '<br>';

echo 'Country Code 3: ' . $country_code3 . '<br>';
|

echo 'Country Name: ' . $country_name . '<br>';

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+)
