用nginx做了一下反向代理，得到的ip地址都是127.0.0.1

nginx反向代理配置时，一般会添加下面的配置：

      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header REMOTE-HOST $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

location / {

　　　proxy_pass http://127.0.0.1:10678;

　　　proxy_set_header Host $host;

        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header REMOTE-HOST $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
