我正在尝试设置芹菜以在生产中运行。我一直按照这里的说明进行操作：
https://www.linode.com/docs/development/python/task-queue-celery-rabbitmq/#start-the-workers-as-daemons
我目前正在执行步骤#7，即"sudo systemctl start celeryd"。当我运行这个时，我被告知芹菜服务失败了。我已经运行了"journalctl -xe"来查找日志详细信息，我在下面复制了这些详细信息。
我对芹菜很陌生，所以我发现很难解释日志文件以找出出了什么问题，所以任何帮助将不胜感激。如果需要更多信息，请询问，我会尽力提供。

从 ExecStart、ExecStop 和 ExecRestart(在您的 celeryd.service 中(中删除/bin/sh -c。
假设您在 /home/celery/venv 中有一个虚拟环境，并且在此环境中安装了 Celery，那么您的 ExecStart(和其他 Exec* 行(应如下所示：
ExecStart=/home/celery/venv/bin/celery multi start ${CELERYD_NODES}
-A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE}
--logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL}
${CELERYD_OPTS}'
要创建虚拟环境，请执行以下操作： python3 -m venv /home/celery/venv
如果芹菜用户是在不同的路径中创建的，则将上面代码中的/home/celery更改为芹菜用户的相应"家"......
更新：如果您使用了与Linode页面上相同的配置文件，则可以使用ExecStart=${CELERY_BIN} multi start...
