如何修复 "Error Removing corrupted schedule file 'celerybeat-schedule': error('Bad magic number',)r"

Question

我可以运行使用终端中的命令正常打芹菜，但是当我在 aws 中转到运行时，出现以下错误：

[2019-07-10 11:30:35,166: ERROR/MainProcess] Removing corrupted schedule file 'celerybeat-schedule': error('Bad magic number',)
    Traceback (most recent call last):
      File "/opt/python/run/venv/local/lib/python3.6/site-packages/kombu/utils/objects.py", line 42, in __get__
        return obj.__dict__[self.__name__]
    KeyError: 'scheduler'

    During handling of the above exception, another exception occurred:

    Traceback (most recent call last):
      File "/opt/python/run/venv/local/lib/python3.6/site-packages/celery/beat.py", line 476, in setup_schedule
        self._store = self._open_schedule()
      File "/opt/python/run/venv/local/lib/python3.6/site-packages/celery/beat.py", line 466, in _open_schedule
        return self.persistence.open(self.schedule_filename, writeback=True)
      File "/usr/lib64/python3.6/shelve.py", line 243, in open
        return DbfilenameShelf(filename, flag, protocol, writeback)
      File "/usr/lib64/python3.6/shelve.py", line 227, in __init__
        Shelf.__init__(self, dbm.open(filename, flag), protocol, writeback)
      File "/usr/lib64/python3.6/dbm/__init__.py", line 94, in open
        return mod.open(file, flag, mode)
    _gdbm.error: Bad magic number

有人可以帮我弄明白哪里出了问题吗？

Answer 1

停止芹菜服务
删除节拍文件，像这样celerybeat-schedule.db
然后重新启动服务

Answer 2

最直接的修复方法很简单：

停止 Celery 节拍进程。
删除 celerybeat-schedule 文件。
启动 Celery 节拍进程。

我运行 Celery 在 AWS 上击败了很多年，到目前为止还没有遇到任何问题。

Answer 3

取自 site.

Beat 需要将任务的最后运行次存储在本地数据库文件中（默认名为 celerybeat-schedule），因此它需要在当前目录中写入，或者您可以指定此文件的自定义位置：

celery -A proj beat -s /home/celery/var/run/celerybeat-schedule
