　　使用变量查找用户地理位置geoip模块;默认未启用此功能；--with-http_geoip_module 编译进去

安装模块依赖的库

yum -y install GeoIP GeoIP-devel GeoIP-data

编译安装依赖库

wget https://github.com/maxmind/geoip-api-c/releases/download/v1.6.12/GeoIP-1.6.12.tar.gz

tar xf GeoIP-1.6.12.tar.gz

cd GeoIP-1.6.12/

./configure

make && make install

重新编译nginx

[root@python nginx-1.15.9]# ./configure --prefix=/data/web --sbin-path=/usr/bin --user=nginx --group=nginx --with-http_stub_status_module --with-http_auth_request_module --with-http_sub_module --add-module=/root/nginx-http-concat --with-http_addition_module --with-http_

secure_link_module --with-http_geoip_module

[root@python nginx-1.15.9]# make

[root@python nginx-1.15.9]# mv /usr/bin/nginx{,.07.13.16.31}

Context: http

　　变量介绍

geoip_city 提供的变量

配置在http字段配置

server {

	server_name split_clients.com;
