#下载免费的geo_coundty数据库
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz

指令

geoip_country

syntax: geoip_country path/to/db.dat;

default: none

context: http

The directive indicates the path to the .dat file used for determining the visitor's country from the IP-address of the client. When set the module makes available the following variables:

dat文件用于判断访问者IP中的国家。当前模块下可用的变量 :

$geoip_country_code; -国家名的前两个字母, 如, "RU", "US".
$geoip_country_code3; - 国家名的前三个字母, 如, "RUS", "USA".
$geoip_country_name; -国家名称, 如, "Russian Federation", "United States".

If you only need the country's name, you can just set the geoip_country database(1.1M), while the geoip_city database is much bigger(43M) and all the databses will be cached in memory.

如果你只需要国家，你只需设置geoip_country数据库(1.1M), 但城市的ip数据库就比较大(43M)并且将加载到内存当缓存。
