Nginx 真实 IP 日志记录不起作用？

我有以下 nginx 配置：

worker_processes auto;
daemon off;
error_log /dev/stdout warn;
include /etc/nginx/modules/*.conf;

events {

}

http {
  real_ip_header X-Forwarded-For;
  real_ip_recursive on;
  set_real_ip_from 192.168.2.1;

  server_tokens off;
  default_type application/octet-stream;
  log_format json_combined escape=json
  '{'
  '"remote_addr":"$remote_addr",'
  '"request":"$request",'
  '"real_ip": "$realip_remote_addr",'
  '"http_x_real_ip": "$http_x_real_ip"'
  '}';
  access_log /dev/stdout json_combined;

  server {
    location / {
      root /content/;
    }  
  }
include /etc/nginx/conf.d/*.conf;
}

我的期望是realip_remote_addr变量应该在标头中具有最后一个不受信任的地址X-Forwarded-For。但是，当我提出这样的请求时：

$ curl -v --header "X-Forwarded-For:10.1.1.1,192.168.2.1" localhost

日志显示127.0.0.0.1和remote_addr变量realip_remote_addr。

这是我的 nginx 版本：

有什么想法我做错了吗？

该设置set_real_ip_from 192.168.2.1意味着 nginx 将只信任X-Forwarded-For从该 IP 地址发送的标头。在您的测试中，标头来自 127.0.0.1，因此 nginx 会忽略该标头。
