일단 nginx 에 geoip 모듈이 적재되어 컴파일 되어 있어야 합니다.
대부분 패키지 설치하실테니... 이미 적용되어 있으실 겁니다.
안되어 있으면 nginx 컴파일 다시 설치 하셔야 합니다.

nginx -V

root@server1:~# nginx -V
nginx version: nginx/1.10.0 (Ubuntu)

이제 젤루 중요한 geoip 데이터 파일이 있어야 합니다.
아래처럼 수동으로 받아도 좋지만 패키지 설치하시는 게 좋습니다.

자동

yum install geoip

수동

mkdir /etc/nginx/geoip

cd /etc/nginx/geoip
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
gunzip GeoIP.dat.gz
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gunzip GeoLiteCity.dat.gz

대부분 패키지 설치 하시면 /usr/share/GeoIP/GeoIP.dat 여기가 경로일 겁니다.

자 이제 설정을 해 볼까요? 2가지 입니다. 대부분...

1. nginx.conf 파일에 geoip 경로 넣기
2. fastcgi_params 파일에 해당 설정 넣기...

도시 정보는 대부분 잘 안씁니다. 정확성도 떨어지고 하니....
나라코드하고 나라이름 정도만 설정해 두세요... proxy 는 그냥 참고만 하세요.. 거의 사용 안 하실테니...

 

Now we configure nginx. Open /etc/nginx/nginx.conf...

nano /etc/nginx/nginx.conf

... and add the geoip_country and geoip_city directives to the http {} container:

[...]
http {

 ##
 # Basic Settings
 ##

 geoip_country /etc/nginx/geoip/GeoIP.dat; # the country IP database
 geoip_city /etc/nginx/geoip/GeoLiteCity.dat; # the city IP database
[...]

The geoip_country directive makes the following variables available:

• $geoip_country_code - two-letter country code, for example, RU, US.
• $geoip_country_code3 - three-letter country code, for example, RUS, USA.
• $geoip_country_name - the (verbose) name of the country, for example, Russian Federation, United States, etc.

The geoip_city directive provides 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 - if available.
• $geoip_region - the name of region (province, region, state, province, federal land, and the like), for example, Moscow City, DC - if available.
• $geoip_city - the name of the city, for example, Moscow, Washington, Lisbon, etc. - if available.
• $geoip_postal_code - zip code or postal code - if available.
• $geoip_city_continent_code - if available.
• $geoip_latitude - latitude - if available.
• $geoip_longitude - longitude - if available.

In order to make these variables available to your PHP scripts as well, we must set a few fastcgi_param directives. It is best to do this in the file /etc/nginx/fastcgi_params where the other fastcgi_param directives are:

nano /etc/nginx/fastcgi_params

[...]
### SET GEOIP Variables ###
fastcgi_param GEOIP_COUNTRY_CODE $geoip_country_code;
fastcgi_param GEOIP_COUNTRY_CODE3 $geoip_country_code3;
fastcgi_param GEOIP_COUNTRY_NAME $geoip_country_name;

fastcgi_param GEOIP_CITY_COUNTRY_CODE $geoip_city_country_code;
fastcgi_param GEOIP_CITY_COUNTRY_CODE3 $geoip_city_country_code3;
fastcgi_param GEOIP_CITY_COUNTRY_NAME $geoip_city_country_name;
fastcgi_param GEOIP_REGION $geoip_region;
fastcgi_param GEOIP_CITY $geoip_city;
fastcgi_param GEOIP_POSTAL_CODE $geoip_postal_code;
fastcgi_param GEOIP_CITY_CONTINENT_CODE $geoip_city_continent_code;
fastcgi_param GEOIP_LATITUDE $geoip_latitude;
fastcgi_param GEOIP_LONGITUDE $geoip_longitude;

(Make sure you have the line include /etc/nginx/fastcgi_params; in your location ~ .php$ {} container in your vhost configuration, because otherwise, the above configuration is useless for your vhost.)

If you use nginx as a reverse proxy and want to pass the GeoIP variables to the backend, you should create/edit the file /etc/nginx/proxy.conf...

nano /etc/nginx/proxy.conf

... and add the following lines to it:

[...]
### SET GEOIP Variables ###
proxy_set_header GEOIP_COUNTRY_CODE $geoip_country_code;
proxy_set_header GEOIP_COUNTRY_CODE3 $geoip_country_code3;
proxy_set_header GEOIP_COUNTRY_NAME $geoip_country_name;

proxy_set_header GEOIP_CITY_COUNTRY_CODE $geoip_city_country_code;
proxy_set_header GEOIP_CITY_COUNTRY_CODE3 $geoip_city_country_code3;
proxy_set_header GEOIP_CITY_COUNTRY_NAME $geoip_city_country_name;
proxy_set_header GEOIP_REGION $geoip_region;
proxy_set_header GEOIP_CITY $geoip_city;
proxy_set_header GEOIP_POSTAL_CODE $geoip_postal_code;
proxy_set_header GEOIP_CITY_CONTINENT_CODE $geoip_city_continent_code;
proxy_set_header GEOIP_LATITUDE $geoip_latitude;
proxy_set_header GEOIP_LONGITUDE $geoip_longitude;

(Make sure you use the line include /etc/nginx/proxy.conf; in your nginx proxy configuration because otherwise, the backend cannot use the GeoIP variables.)
 

자 이제 설정 다끝났습니다. nginx 하고 php-fpm 다시 시작하시면 됩니다.
예제 파일 하나 만드셔서 아래 입력 하시고 테스트 해 보세요..
 

<html>
<body>
<?php

$geoip_country_code = getenv(GEOIP_COUNTRY_CODE);
/*
$geoip_country_code = $_SERVER['GEOIP_COUNTRY_CODE']; // works as well

$geoip_country_name = getenv(GEOIP_COUNTRY_NAME);

$geoip_city_country_code = getenv(GEOIP_CITY_COUNTRY_CODE);
