Question

我正在使用ubuntu 16和systemd来运行celery作为daemon.i也创建了单元文件，但我无法将celery作为服务运行。为什么会出现这个错误？

/etc/systemd/system/celery.service

[Unit]
Description=Celery Service
After=network.target

[Service]
Type=forking
User=celery
Group=celery
EnvironmentFile=-/etc/default/celery
WorkingDirectory=/srv/weaver/src
ExecStart=/bin/sh -c '${CELERY_BIN} multi start ${CELERYD_NODES} \
  -A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE} \
  --logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'
ExecStop=/bin/sh -c '${CELERY_BIN} multi stopwait ${CELERYD_NODES} \
  --pidfile=${CELERYD_PID_FILE}'
ExecReload=/bin/sh -c '${CELERY_BIN} multi restart ${CELERYD_NODES} \
  -A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE} \
  --logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'

Answer 1

我刚刚遇到了这个问题。我的问题是配置问题。特别是，我没有设定 CELERYD_LOG_LEVEL 在我的环境文件中。（在你的情况下是/ etc / default / celeryd）。看起来你犯了同样的错误。

（我还有一些我需要解决的其他配置问题。我通过在命令行上运行celery来发现这些问题。）

Answer 2

我有同样的症状，原来是权限。

在我的情况下，类似：

chmod o+x /srv/weaver/src

对它进行了排序。

请注意：这不是不是启用所需权限的最佳方法，但这与此答案无关。

celery守护进程使用systemd没有运行
