Celery守护进程: celery.service:在步骤USER spawning /home/mike/movingcollage/movingcollageenv/bin/celery:失败没有这样的进程

Question

当我在systemctl start celery.service之后执行journalctl -f时，我会得到

Mar 21 19:14:21 ubuntu-2gb-nyc3-01 systemd[1]: Reloading.
Mar 21 19:14:21 ubuntu-2gb-nyc3-01 systemd[1]: Started ACPI event daemon. 
Mar 21 19:14:25 ubuntu-2gb-nyc3-01 systemd[21431]: celery.service: Failed at step USER spawning /home/mike/movingcollage/movingcollageenv/bin/celery: No such process
Mar 21 19:14:25 ubuntu-2gb-nyc3-01 systemd[1]: Starting celery service...
Mar 21 19:14:25 ubuntu-2gb-nyc3-01 systemd[1]: celery.service: Control process exited, code=exited status=217
Mar 21 19:14:25 ubuntu-2gb-nyc3-01 systemd[1]: Failed to start celery service.
Mar 21 19:14:25 ubuntu-2gb-nyc3-01 systemd[1]: celery.service: Unit entered failed state.
Mar 21 19:14:25 ubuntu-2gb-nyc3-01 systemd[1]: celery.service: Failed with result 'exit-code'.

这是我的celery.service配置：

[Unit]
Description=celery service
After=network.target

[Service]
#PIDFile=/run/celery/pid
Type=forking
User=celery
Group=celery
#RuntimeDirectory=celery  
WorkingDirectory=/home/mike/movingcollage
ExecStart=/home/mike/movingcollage/movingcollageenv/bin/celery multi start 3 -A movingcollage "-c 5 -Q celery -l INFO"
ExecReload=/home/mike/movingcollage/movingcollageenv/bin/celery multi restart 3
ExecStop=/home/mike/movingcollage/movingcollageenv/bin/celery multi stopwait 3

[Install]
WantedBy=multi-user.target

有人知道哪里出了问题吗？提前感谢

Answer 1

对于celery multi，我认为最好使用Type=oneshot。芹菜可以启动许多工作进程，每个进程都有自己的PID。

我这样开始我的celery：

celery multi start 2\
-A my_app_name\
--uid=1001 --gid=1001\
-f /var/log/celery/celery.log\
--loglevel="INFO"\
--pidfile:1=/run/celery1.pid\
--pidfile:2=/run/celery2.pid

当然，在您的示例中，uid、gid和所有路径将是不同的。

Answer 2

您需要更改：

User=celery
Group=celery

对于您的用户和组，在我的例子中：

User=ubuntu
Group=ubuntu
