 ip based geographic lookups... 

 Module: mod_geoip 

 .. contents:: Table of Contents 


 :Packages: GeoIP C API & Library ( 


 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.  

 ( - GeoIP.dat.gz for Countries, GeoLiteCity.dat.gz for Countries & Cities) 


 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.  

 1) Download mod_geoip.c ( 
    - (for lighttpd 1.5 use and rename it to mod_geoip.c 
 2) Copy mod_geoip.c into lighttpd src directory. 
 3) Edit your src/ and add this after the last module:  


         lib_LTLIBRARIES += 
         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 

 4) 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//] 

 5) Make sure /usr/local/lib is in your file and rebuld the ld database (using: ldconfig).  

 6) Add to the config file      server.modules    = ("mod_geoip")          [j lightstone//] 

 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. 

 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. 


 Every database sets it's own ENV: 

 GeoIP (Country): 







 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. 

 Config-file :: 

  geoip.db-filename = "/your-geoip-db-path/GeoLiteCity.dat" 
  geoip.memory-cache = "enable" 

 index.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 "</body>\n</html>"; 

 country based redirect 

 Config-file :: 

  $HTTP["host"] =~ "" { 
      url.rewrite = ( "" => "/redirect.php") 

 redirect.php :: 

         $country_code = $_SERVER['GEOIP_COUNTRY_CODE']; 
         header ('Location: http://' . $country_code . ''); 

 .. 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+) 

 Patches are available to implement redirects based on mod_geoip: 

 mod_geoip.c ( 

 mod_geoip.c for lighttpd 1.5.x (
