我有一个需要像这样执行的python程序;
$ sudo python my_awesome_program.py
现在我想用celery运行这个程序的数千个实例,当然还有不同的参数。问题是当芹菜试图执行我的程序时它失败了,原因是它没有sudo
访问权。
我怎样才能让我的芹菜工人有sudo
的权力来运行这个程序?
我已经尝试过sudo访问我的用户了。改变了芹菜服务所有者等。
可能是一个愚蠢的问题,但我迷路了。
P.S
的 task.py

答案 0 :(得分:1)
您需要在设置中设置CELERYD_USER参数。
看看这里:http://celery.readthedocs.org/en/latest/tutorials/daemonizing.html
如果您正在使用主管,那么在您的芹菜主管中,您需要这样做:
user=<user-you-want>
此外,在Example Configuration部分下,明确表示不会将您的员工作为特权用户运行。
