说下我的环境，我有一台美国linux 服务器，一台美国的windows 2003 ,一台本的XP。机器，其他测试用户都是，QQ群里的朋友，好了开始测试
linux : 75.125.x.x //美国
win2003 : 74.55.x.x // 美国
XP ：localhost // 北京
测试转发，美国用户~转发到 www.google.cn
电信转发到 我的一台 公网的 apache 默认页面
网通转发到 我的一台 公网业务服务器！！
1.下载安装nginx.
shell $> get http://sysoev.ru/nginx/nginx-0.8.13.tar.gz
shell $> tar zxvf nginx-0.8.13.tar.gz
shell $> cd nginx-0.8.13
shell $>apt-get install libgeoip-dev
shell $> ./configure --prefix=/usr/local/nginx --with-http_flv_module --user=www --group=www --with-http_gzip_static_module --with-http_geoip_module
shell $> make
shell $> make install
2.下载GeoLiteCity.dat.gz 数据库~
shell $> wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
shell $> gzip -d GeoLiteCity.dat.gz
shell $> mv GeoLiteCity.dat /usr/local/nginx/conf/GeoLiteCity.dat
3.修改配置文件实现 地区性质负载
shell $> cd /usr/local/nginx/conf
shell $> cat nginx.conf

worker_connections 1024;
}

}
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {

}
}
}
4.测试，用不同地方的机器做测试~
我是北京用户，访问
我是北京用户访问的是默认页面是因为我没有 把 22 数字填加到 配置文件里。我是为了方便测试！大家要是用在生产上要把 22加到
if ($geoip_region ~ "(05|08|09|10|12|17|18|19|20|24|25|26)")
没有匹配到，就访问了默认页面~~
成都朋友帮忙访问：
广州的朋友帮忙访问：
河北朋友帮忙访问：
美国 win2003 访问：
直接访问 电信的 服务器 和 网通服务器
59.151.X.X; 75.125.X.X;
直接访问 网通 59.151.X.X
直接访问 电信服务器 75.125.X.X
下面我来解释一下
if ($geoip_region ~ "(01|02|03|04|06|07|11|13|14|15|16|21|23|29|30|31|32|33)")
这些数字代表的是中国省份地区~~

CN,31,"Hainan"
CN,32,"Sichuan"
CN,33,"Chongqing"
GeoLiteCity.dat 更多变量请看 wiki 我这里只用到两个变量一个是$geoip_region 一个是$geoip_city_country 第一个是 地区，第二个变量是国家只取 两个字母简写！
geoip_city
syntax: geoip_city path/to/db.dat;
default: none
context: http
The directive indicates the path to the .dat file used for determining countries, regions and cities from IP-address of the client. When set the module makes available the following variables:
$geoip_city_country_code; - two-letter country code, for example, "RU", "US". $geoip_city_country_code3; - three-letter country code, for example, "RUS", "USA". $geoip_city_country_name; - the name of the country, for example, "Russian Federation", "United States". $geoip_region; - the name of region (province, region, state, province, federal land, and the like), for example, "Moscow City", "DC". $geoip_city; - the name of the city, for example, "Moscow", "Washington". $geoip_postal_code; - postal code. PS: 我只是根据南方电信，北方网通来区分的~~ 我是北京用户访问的是默认页面是因为我没有 把 22 数字填加到 配置文件里。我是为了方便测试！大家要是用在生产上要把 22加到
if ($geoip_region ~ "(05|08|09|10|12|17|18|19|20|24|25|26)")
网通里~ 不过 开源的 geoip 还是有些不准确的~~~只能给他 75 分~~
