回复了 hanssx 创建的主题 › Python › flask 程序使用 websocket，部署使用 gunicorn， gunicorn 导致 websocket 运行有问题
@itertools 确实，老哥，能加您个 QQ 吗？想感谢您一下，gevent+flask-socketio 就会一直发请求并且 pending，eventlet 则不会，怎么会这样我也不明白，我的扣扣 9614 六 2392，期待老哥，哈哈。

@itertools 我晕，我本地不加 gunicorn，socketio.run(app=app, host='0.0.0.0', port=5000, debug=True)，指定 async_mode='gevent'，也会一直 pending，一直请求。。。

@itertools 我 flask 应用程序的启动代码：socketio.run(app=app, host='0.0.0.0', port=5000, debug=True)
其中 socketio 初始化时，指定了 async_mode='gevent'，是这个原因吗？然后 gunicorn 也使用了 gevent。

@itertools 是的，不支持 py3，真是我的锅，第一次部署花了很多时间，使用了 gevent 之后没有 402 错误了，但是会一直 pending，gunicorn 日志显示好像是心跳包，正在找办法关了它。。。

清理了 gunicorn 进程，抛弃了 websocket-gevent，使用了 gevent，gunicorn -b 127.0.0.1:5000 -k gevent -w 1 module:app，不再报 402 错误了，但是程序还是会一直 pending，一直发请求。。。

开启了 flask-socketio 的日志，现在重新启动，ps -ef | grep guni 出现 2 行，其中 1 行是 work，work 数应该没错，日志现在报错，继续搜索解决方案，

@itertools 打扰，我已经重新清理了之后使用 sudo kill -9，确认网站访问不了，然后重新 supervisord -c /etc/supervisord.conf
问题依然还在，日志中是这样，请问这是 work 吗？这和我在 supervior conf 中配置的不一样啊，我用了参数-w 1 呀。

这是 flask-socketio 官网给的例子，说了一大堆英文，反正就是要用 gunicorn 就要那么写，如果搭配 gevent 的话，
https://flask-socketio.readthedocs.io/en/latest/#gunicorn-web-server
最后命令是这么写的，
gunicorn -b 127.0.0.1:5000 -k geventwebsocket.gunicorn.workers.GeventWebSocketWorker -w 1 module:app

但是这是 group 下有几个任务完成了，而不是每个任务的完成进度，不一样吧。
