nginx之geoip模块的安装和使用

OS：CentOS Linux release 7.5.1804 (Core)

http_geoip_module模块,需要geoip库支持：

yum -y install geoip-devel

编译的参数：

[root@host conf]# nginx -V
nginx version: nginx/1.15.2
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) 
built with OpenSSL 1.0.2j 26 Sep 2016
TLS SNI support enabled
configure arguments: --prefix=/application/nginx-1.15.2 --with-http_stub_status_module --with-openssl=/root/openssl --add-module=/root/nginx-ct-1.3.1 --with-http_v2_module --with-http_ssl_module --with-http_gzip_static_module --with-threads --with-http_realip_module --with-stream --with-http_geoip_module

下载两个ip数据包直接放在nginx的conf目录并解压：

wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
wget http://www.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz

在nginx.conf的http字段加载ip库：

geoip_country GeoIP.dat;
geoip_city GeoLiteCity.dat;

配置文件如下

geoip_country GeoIP.dat;
geoip_city GeoLiteCity.dat;


server {
listen 80;
server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root html;
index index.html index.htm;
}

#Fujian 
if ($geoip_region = 07) {
rewrite ^/index.html http://172.96.218.243/cn permanent;
}

#japan
if ($geoip_country_code = "JP"){
rewrite ^/index.html http://172.96.218.243/jp permanent;
}

#usa
if ($geoip_country_code = "US"){
rewrite ^/index.html http://172.96.218.243/us permanent;
}

IP信息，具体可以在官网查询：http://www.maxmind.com/en/geoip_demo

相应的省份代码如下：

CN,01,”Anhui”
CN,02,”Zhejiang”
CN,03,”Jiangxi”
CN,04,”Jiangsu”
CN,05,”Jilin”
CN,06,”Qinghai”
CN,07,”Fujian”
CN,08,”Heilongjiang”
CN,09,”Henan”
CN,10,”Hebei”
CN,11,”Hunan”
CN,12,”Hubei”
CN,13,”Xinjiang”
CN,14,”Xizang”
CN,15,”Gansu”
CN,16,”Guangxi”
CN,18,”Guizhou”
CN,19,”Liaoning”
CN,20,”Nei Mongol”
CN,21,”Ningxia”
CN,22,”Beijing”
CN,23,”Shanghai”
CN,24,”Shanxi”
CN,25,”Shandong”
CN,26,”Shaanxi”
CN,28,”Tianjin”
CN,29,”Yunnan”
CN,30,”Guangdong”
CN,31,”Hainan”
CN,32,”Sichuan”
CN,33,”Chongqing”

具体查询http://dev.maxmind.com/static/maxmind-region-codes.csv，也可以通过下载csv版本的ip库手动查询，比如搜索Guanzhou，会出现,”CN”,”30″,”Guangzhou”，这个30就是省份了。
