1.Nginx默认上传文件大小1M,超过无法上传，进行如下设置
client_max_body_size 100m;  #上传文件100M

2.$server_port ：nigix监听的端口
$proxy_port ： 服务器真正访问的端口

#设置请求头"Host"值（为入口域名和端口）
proxy_set_header Host  $http_host;

#设置为upstream对应服务器（IP和端口）
proxy_set_header Host  $proxy_host;

#设置为入口Host和当前nginx监听端口
proxy_set_header Host $host:$server_port;
