如何在CloudFlare下Nginx实现访客真实IP网站日志?

做英文内容站套上Cloudflare CDN既可以加快访问速度又可以避免被攻击。可是如果需要通过网站日志分析蜘蛛来访,是否被采集、被攻击等情况,但日志上全部都是CDN(cloudflare)节点的 IP。那么在用CDN加速的同时,如何获取访客真实IP并记录到日志上呢?

查看CloudFlare官方文档《Restoring original visitor IPs: Logging visitor IP addresses》,在这种情况下可以通过的realip模块来获取用户的IP,这里以cloudflare和lnmp一键包为例。

1、为nginx添加with-http_realip_module模块

修改lnmp.conf文件,并且升级nginx即可。

cd /root/lnmp1.7
vi lnmp.conf

在lnmp.conf添加–with-http_realip_module,如下。

Nginx_Modules_Options='--with-http_realip_module'

升级nginx

./upgrade.sh nginx

http://nginx.org/en/download.html 查看版本,然后输入合适的版本。
等待升级完成即可。

2、设置nginx配置

修改网站的配置文件

/usr/local/nginx/conf/nginx.conf

在server后面的http{}中添加如下内容

set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 104.16.0.0/12;
set_real_ip_from 108.162.192.0/18;
set_real_ip_from 131.0.72.0/22;
set_real_ip_from 141.101.64.0/18;
set_real_ip_from 162.158.0.0/15;
set_real_ip_from 172.64.0.0/13;
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 188.114.96.0/20;
set_real_ip_from 190.93.240.0/20;
set_real_ip_from 197.234.240.0/22;
set_real_ip_from 198.41.128.0/17;
set_real_ip_from 2400:cb00::/32;
set_real_ip_from 2606:4700::/32;
set_real_ip_from 2803:f800::/32;
set_real_ip_from 2405:b500::/32;
set_real_ip_from 2405:8100::/32;
set_real_ip_from 2c0f:f248::/32;
set_real_ip_from 2a06:98c0::/29;
real_ip_header CF-Connecting-IP;
real_ip_recursive on;

重载nginx配置生效:

/usr/local/nginx/sbin/nginx -s reload

以下是nginx.conf例子文件
