proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

$proxy_add_x_forwarded_for 这个变量会将所有代理的IP都包含其中，而第一个IP就是用户的真实IP，值的格式如下：TTP_X_FORWARDED_FOR => remote_ip,proxy1_ip, proxy2_ip,... ...

proxy_set_header X-Real-IP                  $remote_addr; 
proxy_set_header X-Forwarded-For     $proxy_add_x_forwarded_for; 
set_real_ip_from 118.89.52.242; 
real_ip_header X-Forwarded-For;

set_real_ip_from：指定上游服务器

real_ip_header：指定获取访客IP的位置

两个语句可以放置在http、server和location区块中，放置在http区块中将对所有的虚拟空间生效。
