业务服务：gunicorn + flask
后台服务：celery
主业务主文件转换与上传，比较耗时，所以用 celery 跑后台服务
本地(Mac book):
能正常异步跑，自动切换多个 worker,无阻塞，是理想效果:

如上运行日志
本地正常运行，有 3 个 worker：ForkPoolWorker-8 、ForkPoolWorker-1 和 ForkPoolWorker-2 ，并行处理，服务不阻塞
远程服务器只能同步运行，且只有一个固定的 worker: ForkPoolWorker-7,服务阻塞的
是不是远程哪里的配置不对，远程服务器启动信息摘要也跟本地一样：

请各位指教，是不是哪里配置有问题
