nginx获取真实ip

工作过程中碰到问题，问题原因是后台服务获取不了前台真实ip，需要在nginx配置中添加如下所示:

location / {
		proxy_pass       http://127.0.0.1:8080/;
		}
		proxy_redirect    off;
		proxy_set_header  Host             $host;
		proxy_set_header  X-Real-IP        $remote_addr;
		proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
