GeoIP介绍:
什么是GepIP ?
所谓GeoIP,就是通过来访者的IP, 定位他的经纬度,国家/地区,省市,甚至街道等位置信息。这里面的技术不算难题,关键在于有个精准 的数据库。有了准确的数据源就奇货可居赚点小钱,可是发扬合作精神,集体贡献众人享用是我们追求的。
GeoIP如何使用?
首先我们需要数据信息,所以先获取一个免费的数据库:GeoIP.dat.gz ,接着解压得到:GeoIP.dat, 然后就是对数据文件的按需操作,这边范例使用的是PHP。
GeoIP + PHP的使用
方法一:
下载 GeoIP 的 PHP 文件geoip.inc。打包下载
复制代码 代码如下:

include("geoip.inc.php");
// 打开数据文件
$gi = geoip_open("GeoIP.dat",GEOIP_STANDARD);
// 获取国家代码
$country_code = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']);
echo "Your country code is: $country_code ";
// 获取国家名称
$country_name = geoip_country_name_by_addr($gi, $_SERVER['REMOTE_ADDR']);
echo "Your country name is: $country_name ";
// 关闭文件
geoip_close($gi);

注:在本地测试的话因 为$_SERVER['REMOTE_ADDR']和$_SERVER['REMOTE_ADDR']可能是127.0.0.1,所 以输出的内容为空。可以自己带入IP测试

方法二:
把 GeoIP 安装成 PHP 扩展
yum install GeoIP GeoIP-data GeoIP-devel

下载 GeoIP 数据库
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gzip -d GeoLiteCity.dat.gz
mv GeoLiteCity.dat /var/lib/GeoIP/GeoIPCity.dat

下载 GeoIP 的 PECL 扩展
下载地址 http://pecl.php.net/package/geoip
wget -c http://pecl.php.net/get/geoip-1.0.7.tgz
tar -zxvf geoip-1.0.7.tgz

安 装 GeoIP 的 PECL 扩展
cd geoip-1.0.7
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-geoip
make
make install

在 php.ini 里加上
extension=geoip.so
接着重启一下 php 就行了
现在,你可以使用 php 手册里的 GeoIP 部份函数了
