1.安装epel源
wget https://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm rpm -ivh epel-release-6-8.noarch.rpm
2.首先安装 MaxMind 的 GeoIP 库,其官网是： http://www.maxmind.com,MaxMind 提供了免费的 IP 地域数据库（GeoIP.dat），不过这个数据库文件是二进制的
yum install GeoIP GeoIP-update GeoIP-devel -y
3.nginx安装
./configure --prefix=/usr/local/nginx-1.10.1 --user=nginx --group=nginx --with-pcre --with-threads --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_gzip_static_module --with-http_realip_module --with-http_geoip_module --with-google_perftools_module #优化参数，可不选 make make install
4.测试geoip
geoiplookup -f /usr/share/GeoIP/GeoLiteCity.dat 202.96.134.133 #获取不到城市 GeoIP City Edition, Rev 1: CN, N/A, N/A, N/A, N/A, 34.772499, 113.726601, 0, 0 wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz #重新下载新的城市库 cp GeoLiteCity.dat GeoLiteCity.dat.bak gunzip GeoLiteCity.dat geoiplookup -f /usr/share/GeoIP/GeoLiteCity.dat 202.96.134.133 #正常获取城市 GeoIP City Edition, Rev 1: CN, 30, Guangdong, Guangzhou, N/A, 23.116699, 113.250000, 0, 0
5.配置nginx.conf
vim /usr/local/nginx/conf/nginx.conf ...... include vhost/www.conf; ......
6.配置www.conf
# 加载ip库
geoip_country /usr/share/GeoIP/GeoLiteCountry.dat;
geoip_city /usr/share/GeoIP/GeoLiteCity.dat;
# 地址库解析,国家代码2位，国家代码3位，国家名称
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;
# 所在地区，所在城市
fastcgi_param GEOIP_REGION $geoip_region;
fastcgi_param GEOIP_CITY $geoip_city;
# 邮政编码，所在洲，维度，经度
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;
# 灰度版本
upstream huiduserver {
server 183.2.191.195:8202 weight=1;
}
# 稳定版本
upstream server {
server 183.2.191.195:8201 weight=1;
}
server {
listen 80;
server_name huidu.pin.cn project.pin.com;
# 默认
location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# 灰度版本
if ($geoip_city ~* Guangdong) {
proxy_pass http://huiduserver;
}
if ($geoip_region = 30) {
proxy_pass http://huiduserver;
}
# 稳定版本
proxy_pass http://server;
}
7.指定ip灰度发布
location / {
proxy_redirect off;
proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
if ($remote_addr ~ "101.95.155.134") {
proxy_pass http://huiduserver;
}
proxy_pass http://cgiservers;
}
8.指定US和CN国家返回404
server
if ($geoip_country_code ~* (US|CN)) {
#return 404;
}
9. 参数说明
$geoip_country_code #国家代码2位，如CN $geoip_country_code3 #国家代码3位，如CHN $geoip_country_name #国家完整名称，如China $geoip_region #所在地区 $geoip_city #所在城市，如BeiJing $geoip_postal_code #邮政编码 $geoip_city_continent_code #所在洲，如AS $geoip_latitude #纬度 $geoip_longitude #经度
