问题
I use Celery and Celerybeat in my django powered website. the server OS is Ubuntu 16.04. by using celerybeat, a job is done by a celery worker every 10 minutes. sometimes the worker shuts down without any useful log messages or errors.
So, I want to find a way in order to detect status (On/Off) of celery worker (not Beat), and if it's stopped, restart it automatically.
how can I do that?
thanks
回答1:
In production, you should run Celery, Beat, your APP server etc. as daemons [1] using Supervisor/Upstart/Systemd/.../.... There is a section about this in the Celery documentation. [2]
My favorite tool is Supervisord [3]. Here is Supervisord example configuration for Celery: https://github.com/celery/celery/tree/master/extra/supervisord and here https://github.com/illagrenan/ubuntu-supervisor-configuration is a tutorial about installing Supervisord on Ubuntu.
(...) Supervisord starts processes as its subprocesses, and can be configured to automatically restart them on a crash. (...)
