1.非常重要的结论:server_name对应的是http请求头里的Host字段的值
curl.exe -H "Host: aaa" 10.210.65.73

--------------------------------------------------
proxy_set_header Host $host:$server_port; 这段比较关键之前我没加$server_port就老是到下级请求出现真实端口号

2.获取远程的ip
proxy_set_header X-Real-IP $remote_addr; #获取真实ip
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;#获取代理者的真实ip
