Question

我试图将芹菜投入生产。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”。运行此程序时，我被告知celeryd.service失败。我已经运行'journalctl -xe'来查找日志详细信息，我将其复制到下面。

我对celery还是很陌生，所以在解释日志文件以找出问题所在时遇到了困难，因此，我们将不胜感激。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celery用户是在其他路径中创建的，则将上面代码中的/home/celery更改为celery用户的相应“家” ...

更新：如果您使用与Linode页面上相同的配置文件，则可以使用ExecStart=${CELERY_BIN} multi start...
