1. 安装依赖GeoIP-devel，GeoIP
GeoIP-devel.x86_64 : Development headers and libraries for GeoIPGeoIP.x86_64 : Library for country/city/organization to IP address or hostname mapping
yum install GeoIP.x86_64 GeoIP-devel.x86_64
2. 配置IP数据库GeoIP.dat，GeoLiteCity.dat
wget -N http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gzgunzip GeoIP.dat.gzmv GeoIP.dat /usr/local/share/GeoIP/
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gzgunzip GeoLiteCity.dat.gzmkdir -v /usr/share/GeoIPmv -v GeoLiteCity.dat /usr/share/GeoIP/GeoIPCity.dat
说明 ：GeoIPRegion.dat是付费服务；

3. 安装扩展
git clone git@github.com:billfeller/geoip.git; phpize./configure --with-php-config=/usr/local/php/bin/php-config --with-geoipmake && make install
4. 测试
[root@~/wade/pecllearning/geoip]# /usr/local/php/bin/php -r 'print geoip_country_code3_by_name("220.181.112.244").PHP_EOL;'CHN[root@~/wade/pecllearning/geoip]# /usr/local/php/bin/php -r 'print_r(geoip_record_by_name("php.net"));'Array( [continent_code] => NA [country_code] => US [country_code3] => USA [country_name] => United States [region] => CA [city] => Fremont [postal_code] => 94539 [latitude] => 37.51549911499 [longitude] => -121.8962020874 [dma_code] => 807 [area_code] => 510) 注意，由于本地无GeoIPRegion.dat，调用 geoip_region_by_name 时会报Warning，如下
[root@~/wade/pecllearning/geoip]# /usr/local/php/bin/php -r 'print geoip_region_by_name("220.181.112.244");'PHP Warning: geoip_region_by_name(): Required database not available at /usr/share/GeoIP/GeoIPRegion.dat. in Command line code on line 1 Warning: geoip_region_by_name(): Required database not available at /usr/share/GeoIP/GeoIPRegion.dat. in Command line code on line 1
