apache (apache官網)geoip(maxmind官網)

環境 : CentOS 5.5 x86

安裝 yum repos

wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -Uvh epel-release-5-4.noarch.rpm

安裝 geoip 相關套件

yum install mod_geoip GeoIP GeoIP-devel GeoIP-data zlib-devel httpd mod_php

在 apache 就有 geoip 設定 (/etc/httpd/conf.d/geoip.conf)

LoadModule geoip_module modules/mod_geoip.so
<IfModule mod_geoip.c>
 GeoIPEnable On
 GeoIPDBFile /usr/share/GeoIP/GeoIP.dat
</IfModule>

啟動 apache

service httpd start

寫一個 PHP

<html>
<head>
<title>What is my IP address and Country</title>
</head>
<body>
<?php
 if (getenv(HTTP_X_FORWARDED_FOR)) {
 $pipaddress = getenv(HTTP_X_FORWARDED_FOR);
 $ipaddress = getenv(REMOTE_ADDR);
 echo "Your Proxy IP address is : ".$pipaddress. " (via $ipaddress) " ;
 } else {
 $ipaddress = getenv(REMOTE_ADDR);
 echo "My IP address is : $ipaddress";
 }
 $country = getenv(GEOIP_COUNTRY_NAME);
 echo "<br />My Country : $country";
?>
</body>
</html>

呈現如下

My IP address is : 124.xx.xx.92
My Country : Taiwan

如果要更新 GeoIP.dat 可到 http://dev.maxmind.com/geoip/geolite 下載 Free 的

還可搭配 mod_rewrite 重導那些來源區域到特定地方

# Redirect one country
RewriteEngine on
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^AS$
RewriteRule ^(.*)$ http://www.tecmint.com$1 [R,L]

或阻擋或開放

SetEnvIf GEOIP_COUNTRY_CODE AS BlockCountry
SetEnvIf GEOIP_COUNTRY_CODE US AllowCountry
# ... place more countries here
Deny from all
Deny from env=BlockCountry
Allow from env=AllowCountry
