延长Nginx的反向代理超时时间即可。

server {
     listen 80;
     server_name xxx.com;
     proxy_connect_timeout 600;
     proxy_send_timeout 600;
     proxy_read_timeout 600;
     location / {
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header Host $http_host;
          proxy_pass http://127.0.0.1:8000;
         }
     }
