安装 GeoIP
FreeBSD 7.0-RELEASE-i386 + PHP5 + Apache2.2
# cd /usr/ports/net/pecl-geoip && make install clean
# apachectl restart
# cd ~
# fetch http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz
# gunzip GeoIP.dat.gz
# mv GeoIP.dat /usr/local/share/GeoIP/GeoIP.dat
# fetch http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
# gunzip GeoLiteCity.dat.gz
# mv GeoLiteCity.dat /usr/local/share/GeoIP/GeoIPCity.dat
<?php
echo geoip_database_info(GEOIP_COUNTRY_EDITION);
$country = geoip_record_by_name('wangblog.org');
if($country){
echo "\nThis host is located in: \n";
print_r($country);
}
?>
可以写个定时更新IP地址库的程序：
cd ~ /usr/bin/fetch http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz /usr/bin/gunzip GeoIP.dat.gz mv GeoIP.dat /usr/local/share/GeoIP/GeoIP.dat /usr/bin/fetch http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz /usr/bin/gunzip GeoLiteCity.dat.gz mv GeoLiteCity.dat /usr/local/share/GeoIP/GeoIPCity.dat 以上保存为：update-ipdata-cron.sh crontab -e 添加以下一行，每月5日0点10分运行： 10 0 5 * * /bin/csh /path/to/update-ipdata-cron.sh
