获取Cloudfront回源IP列表
在以下链接获取 ip-ranges.json
https://docs.aws.amazon.com/zh_cn/AmazonCloudFront/latest/DeveloperGuide/LocationsOfEdgeServers.html
筛选出含有 "service": "CLOUDFRONT" 的IP段
配置Nginx
在Nginx的配置文件夹下创建一个 cloudfront_ip.conf 文件，填入以下内容
# 回源IP列表获取到的结果 (2020.4.1) set_real_ip_from 144.220.0.0/16; set_real_ip_from 52.124.128.0/17; set_real_ip_from 54.230.0.0/16; set_real_ip_from 54.239.128.0/18; set_real_ip_from 52.82.128.0/19; set_real_ip_from 99.84.0.0/16; set_real_ip_from 204.246.172.0/24; set_real_ip_from 54.239.192.0/19; set_real_ip_from 70.132.0.0/18; set_real_ip_from 13.32.0.0/15; set_real_ip_from 205.251.208.0/20; set_real_ip_from 13.224.0.0/14; set_real_ip_from 13.35.0.0/16; set_real_ip_from 204.246.164.0/22; set_real_ip_from 204.246.168.0/22; set_real_ip_from 71.152.0.0/17; set_real_ip_from 216.137.32.0/19; set_real_ip_from 205.251.249.0/24; set_real_ip_from 99.86.0.0/16; set_real_ip_from 52.46.0.0/18; set_real_ip_from 52.84.0.0/15; set_real_ip_from 204.246.173.0/24; set_real_ip_from 130.176.0.0/16; set_real_ip_from 205.251.200.0/21; set_real_ip_from 204.246.174.0/23; set_real_ip_from 64.252.128.0/18; set_real_ip_from 205.251.254.0/24; set_real_ip_from 143.204.0.0/16; set_real_ip_from 205.251.252.0/23; set_real_ip_from 204.246.176.0/20; set_real_ip_from 13.249.0.0/16; set_real_ip_from 54.240.128.0/18; set_real_ip_from 205.251.250.0/23; set_real_ip_from 52.222.128.0/17; set_real_ip_from 54.182.0.0/16; set_real_ip_from 54.192.0.0/16; set_real_ip_from 13.124.199.0/24; set_real_ip_from 34.226.14.0/24; set_real_ip_from 52.15.127.128/26; set_real_ip_from 35.158.136.0/24; set_real_ip_from 52.57.254.0/24; set_real_ip_from 18.216.170.128/25; set_real_ip_from 13.52.204.0/23; set_real_ip_from 13.54.63.128/26; set_real_ip_from 13.59.250.0/26; set_real_ip_from 13.210.67.128/26; set_real_ip_from 35.167.191.128/26; set_real_ip_from 52.47.139.0/24; set_real_ip_from 52.199.127.192/26; set_real_ip_from 52.212.248.0/26; set_real_ip_from 52.66.194.128/26; set_real_ip_from 13.113.203.0/24; set_real_ip_from 99.79.168.0/23; set_real_ip_from 34.195.252.0/24; set_real_ip_from 35.162.63.192/26; set_real_ip_from 34.223.12.224/27; set_real_ip_from 52.56.127.0/25; set_real_ip_from 34.223.80.192/26; set_real_ip_from 13.228.69.0/24; set_real_ip_from 34.216.51.0/25; set_real_ip_from 3.231.2.0/25; set_real_ip_from 54.233.255.128/26; set_real_ip_from 18.200.212.0/23; set_real_ip_from 64.252.64.0/18; set_real_ip_from 52.52.191.128/26; set_real_ip_from 3.234.232.224/27; set_real_ip_from 52.78.247.128/26; set_real_ip_from 52.220.191.0/26; set_real_ip_from 34.232.163.208/29; set_real_ip_from 2600:9000:eee::/48; set_real_ip_from 2600:9000:4000::/36; set_real_ip_from 2600:9000:3000::/36; set_real_ip_from 2600:9000:f000::/36; set_real_ip_from 2600:9000:fff::/48; set_real_ip_from 2600:9000:2000::/36; set_real_ip_from 2600:9000:1000::/36; set_real_ip_from 2600:9000:ddd::/48; set_real_ip_from 2600:9000:5300::/40; # 根据请求头获取用户真实IP real_ip_header X-Forwarded-For; real_ip_recursive on;
在对应vhost下新增一行引用上述配置即可，以下仅为示例，目录可能因环境部署差异而不同
include /usr/local/nginx/conf/cloudfront_ip.conf;
重启 Nginx 后生效
