nginx安装GeoIP模块，屏蔽特定地区IP

老板出国访问不了公司的系统，想起当时设置了nginx，只允许中国的IP地址访问。注释掉规则后，老板可以访问公司系统。这里写篇博客，记录一下GeoIP模块的使用。我在aws上启用了一个免费的主机，用的centos的镜像。

[root@localhost ~]# vi /etc/yum.repos.d/nginx.repo 
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/6/$basearch/
gpgcheck=0
enabled=1
[root@localhost ~]# yum install nginx -y
[root@localhost ~]# service nginx start

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

报错，通过yum search geoip查找，发现仓库里没有安装包。

安装epel仓库，yum install epel-release -y，再次查找，仓库里有GeoIP安装包

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

解压后，我就放在了nginx目录下。

4.修改配置文件，使用IP筛选

为方便所有站点使用，我直接在/etc/nginx/nginx.conf中写入加载

load_module /usr/lib64/nginx/modules/ngx_http_geoip_module.so;
load_module /usr/lib64/nginx/modules/ngx_stream_geoip_module.so;
...
geoip_country /etc/nginx/GeoIP.dat;

配置单个站点使用规则，打开/etc/nginx/conf.d/default.conf

set $deny 0;
    if ($geoip_country_code != "CN"){
        set $deny 1;
        return 302 $scheme://$host/405.html;
    }
    if ($deny = 1){
        return 302 $scheme://$host/405.html;
    }

这里设置的，非中国IP不能访问。

走代理测试成功。
