nginx中X-Forwarded-For和X-Real-IP设置

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_pass http://ip:port;

引用X-Forwarded-For和X-Real-IP

$http_x_forwarded_for

$http_x_real_ip

　　

X-Forwarded-For 是个可叠加变量,后面的代理会把前面代理的IP加入X-Forwarded-For变量中
