记得nginx编译时一定要加载geoip这个模块

https://blog.csdn.net/beyond__devil/article/details/52838422   地区代码表

主配置文件geoip模块的配置如下：

geoip_country /usr/local/nginx/conf/GeoIP/GeoIP.dat;
geoip_city /usr/local/nginx/conf/GeoIP/GeoLiteCity.dat;
geo $remote_addr $ip_whitelist {
default 0;
include ip.conf;
}
map $geoip_city $allow_city {
default no;
Jinhua yes;
#Beijing yes;
Shanghai yes;
Guangzhou yes;
Chongqing yes;
Shandong yes;
}

我的vhost目录下的a.conf配置如下

server {
listen 80;
server_name jiaji.com;
access_log /home/nginx/beijing.log;

location / {
root /var/www/web/ABBEIJING/xiqing;
index index.html index.htm index.php;

if ( $geoip_region = "22" ) {       ##这里的22是北京地区
root /var/www/web/ABBEIJING/laohushenhe;
}

if ($allow_city = yes) {
root /var/www/web/ABBEIJING/xiqing;
}

}
}

另一个运用geoip的站点，需求：默认访问/var/www/web/hongb目录，北上广深重庆访问/var/www/web/zhi目录，在允许城市列表（nginx.conf文件里指定的允许城市列表）的城市也是访问/var/www/web/hongb目录

server {
listen 80;
server_name hongb.com;

location / {
root /var/www/web/hongb;
index index.html index.htm index.php;

if ( $geoip_region = "22" ) { ##这里的22是北京地区
root /var/www/web/zhi;
}

if ( $geoip_region = "23" ) { ##这里的23是上海地区
root /var/www/web/jzhi;
}

if ( $geoip_region = "30" ) { ##这里的30是广东地区
root /var/www/web/jzhi;
}

if ( $geoip_region = "32" ) { ##这里的32是四川地区
root /var/www/web/jzhi;
}

if ($allow_city = yes) {
root /var/www/web/hongb;
}
}
}
