python - django celery 击败 DBAccessError

Question

我正在用 celerybeat 运行 django+celery，但出现了这个错误

.../local/lib/python2.7/site-packages/celery/beat.py", line 367, in setup_schedule
    writeback=True)
  File "/usr/lib/python2.7/shelve.py", line 239, in open
    return DbfilenameShelf(filename, flag, protocol, writeback)
  File "/usr/lib/python2.7/shelve.py", line 223, in __init__
    Shelf.__init__(self, anydbm.open(filename, flag), protocol, writeback)
  File "/usr/lib/python2.7/anydbm.py", line 85, in open
    return mod.open(file, flag, mode)
  File "/usr/lib/python2.7/dbhash.py", line 18, in open
    return bsddb.hashopen(file, flag, mode)
  File "/usr/lib/python2.7/bsddb/__init__.py", line 364, in hashopen
    d.open(file, db.DB_HASH, flags, mode)
DBAccessError: (13, 'Permission denied')

我使用 python manage.py celeryd -B 来运行 celery beat。似乎运行 celery worker 不是问题，但是 celerybeat worker 没有初始化。关于在哪里可以找到 celery 试图访问的数据库有什么建议吗？

我正在运行 django=1.5 和 django-celery==3.1.10

我问得太早了!

回答我自己的问题，以防其他人遇到同样的问题。

问题是因为我在我的 django 项目运行的文件夹中没有写权限。

来自文档 ( http://celery.readthedocs.org/en/latest/userguide/periodic-tasks.html#starting-the-scheduler )

Beat needs to store the last run times of the tasks in a local database file (named celerybeat-schedule by default), so it needs access to write in the current directory

通过运行解决了问题

python manage.py celeryd -B -s /path/to/where/i/have/write-access/celerybeat-schedule

希望这对某人有帮助。
