当我执行命令时
netstat -atun | awk '{print $5}' | cut -d: -f1 | sed -e '/^$/d' |sort | uniq -c | sort -n
我看到分配给服务器 IP 的连接数很高
我想查看我的服务器 ip 背后的真实 ip 地址
这是我的 nginx 配置

据我所知，您可以使用其他负载均衡器来执行此操作，但不能使用 nginx。
在 LVS 中，这称为 DR 模式：

在 F5 中，这被称为 npath：
这是 nginx 邮件列表上的一个讨论，其中声称这种行为在 nginx 中是不可能的。

您提到了 realip，这是我能找到的最接近的：
