h1. IP Based Geographic Lookups
{{>toc}}
Module: mod_geoip
h2. Requirements
Packages: GeoIP C API & Library (http://www.maxmind.com/download/geoip/api/c/)
h2. 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.

h1. Installation
*NOTE:* As of 1.4.14 the lighttpd distribution does not include the compile file required to perform a automake in the source directory. Use "automake -a" instead.
# Download the source file (https://redmine.lighttpd.net/attachments/download/1689/mod_geoip_for_1.4.39.c) (http://redmine.lighttpd.net/attachments/716/mod_geoip_for_1.4.c)
- (for lighttpd 1.5 use http://redmine.lighttpd.net/attachments/717/mod_geoip_for_1.5.c)
and rename it to "mod_geoip.c"
# Copy mod_geoip.c into lighttpd src directory.
# Apply https://redmine.lighttpd.net/attachments/download/1688/mod_geoip-for-1.4.39.patch to compile in lighttpd 1.4.39
# (optional) see https://redmine.lighttpd.net/issues/2025 for additional suggested patch
# Edit your src/Makefile.am and add this after the last module:
<pre>
lib_LTLIBRARIES += mod_geoip.la
mod_geoip_la_SOURCES = mod_geoip.c
mod_geoip_la_LDFLAGS = -module -export-dynamic -avoid-version -no-undefined
mod_geoip_la_LIBADD = $(common_libadd) -lGeoIP
</pre>
# Go back to lighttpd root directory and first do: aclocal && automake -a && autoconf, after that do: make clean; ./configure --enable-maintainer-mode; make; make install
*NOTE:* the command of 'make clean' gives error on Fedora 4 and may not be necessary to compile properly. [j lightstone//GlobalAdSales.company]
# Make sure /usr/local/lib is in your ld.so.conf file and rebuld the ld database (using: ldconfig).
# Add to the config file server.modules = ("mod_geoip") [j lightstone//GlobalAdSales.company]
*NOTE:* If using mod_proxy, add mod_geoip BEFORE mod_proxy.
FYI: https://redmine.lighttpd.net/attachments/download/1689/mod_geoip_for_1.4.39.c includes patches from
https://redmine.lighttpd.net/issues/1962
https://redmine.lighttpd.net/issues/2025
h2. Configuration Options
*NOTE:* in lighttpd 1.5.x add the config vars only to the global config - adding into a vhost crashes lighty!
mod_geoip uses two 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.
*NOTE:* mod_geoip will determine the database type automatically so if you enter GeoCity database path it will load GeoCity Env.
h2. Environment
Every database sets it's own ENV:
GeoIP (Country):
<pre>
GEOIP_COUNTRY_CODE
GEOIP_COUNTRY_CODE3
GEOIP_COUNTRY_NAME
</pre>
GeoCity:
<pre>
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
</pre>
h2. Examples
mod_geoip + php
*NOTE:* in lighttpd 1.5.x add the config vars only to the global config - adding into a vhost crashes lighty!
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.

+country based redirect+
Config-file
<pre>
$HTTP["host"] =~ "www.domain.com" {
url.rewrite = ( "" => "/redirect.php")
}
</pre>
redirect.php
<pre>
<?php
$country_code = ( !empty( $_SERVER['GEOIP_COUNTRY_CODE'] ) ) ? $_SERVER['GEOIP_COUNTRY_CODE'] : 'US';
header( 'Location: http://'.strtolower( $country_code ).'.domain.com/' );
exit;
?>
</pre>
Currently redirecting based on mod_geoip through the lighttpd config file is possible with some patches: http://trac.lighttpd.net/trac/ticket/1546. An alternative would be to use mod_magnet.
