什么是GeoIP ?
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的一个数据库。GeoIP有两个版本,一个免费版,一个收费版本。收费版本的准确率和数据更好一些。
GeoIP如何使用?
GeoIP支持多种语言调用,这里我们以PHP为例。
方法一
apt-get install php5-geoip libgeoip1
wget -N -q http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
wget -N -q http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
gzip -d GeoLiteCity.dat.gz
cp GeoLiteCity.dat /usr/share/GeoIP/GeoIPCity.dat
注:这里的路径和编译GeoIP C API所使用的–with-dbdir参数有关。
测试GeoIP
重启Apache
/etc/init.d/apache2 restart
在Web目录下新建一个测试的PHP文件,这里以geoip.php为例:
vi /var/www/geoip.php
$country = geoip_record_by_name('61.128.128.68'); if ($country) { echo 'This host is located in: '; print_r($country); }
print geoip_db_filename(GEOIP_COUNTRY_EDITION);
?>
访问这个文件,如出现下面类似信息,则表示成功了。
This host is located in: Array ( [continent_code] => AS [country_code] => CN [country_code3] => CHN [country_name] => China [region] => 33 [city] => Chongqing
[postal_code] => [latitude] => 29.562799453735 [longitude] => 106.55280303955 [dma_code] => 0 [area_code] => 0 )
wget http://geolite.maxmind.com/download/geoip/api/c/GeoIP.tar.gz
tar xvzf GeoIP.tar.gz
cd GeoIP-1.4.8
./configure
make
make install
pecl install geoip
vi /etc/php5/conf.d/geoip.ini
extension=geoip.so
cp GeoLiteCity.dat /usr/local/share/GeoIP/GeoIPCity.dat

一些编译中常见的错误
如果你的系统中的libtool中的版本低于2.2.6b,可能会出现以下错误提示:
libtool: Version mismatch error. This is libtool 2.2.6 Debian-2.2.6a-4, but the
libtool: definition of this LT_INIT comes from libtool 2.2.6b.
libtool: You should recreate aclocal.m4 with macros from libtool 2.2.6 Debian-2.2.6a-4
解决方法:先执行以下语句后,再重新编译。
autoreconf --force
./configure
make
make install
