我正在尝试使用systemd将celery 4.3.0作为守护进程运行，但是出现了以下错误：
它启动了工作进程，但很快停止了它们。然而，我可以通过键入命令来手动运行worker：
celery -A bin.proj.celery_app worker1
用户是“ssc”，该用户不属于root组，我已经为“ssc”用户在项目上赋予了所需的所有权限。 任何帮助都将不胜感激，我已经花费了太多时间，谢谢。

这里是 celery.service 的内容：
[Unit]

这是相关的配置文件：
# Name of nodes to start
# here we have a single node
#CELERYD_NODES="w1"
# or we could have three nodes:
CELERYD_NODES="worker1 worker2 worker3"
# Absolute or relative path to the 'celery' command:
CELERY_BIN="/usr/local/bin/celery"
#CELERY_BIN="/virtualenvs/def/bin/celery"
# App instance to use
# comment out this line if you don't use an app
CELERY_APP="bin.proj.celery_app"
# or fully qualified:
#CELERY_APP="proj.tasks:app"
# How to call manage.py
CELERYD_MULTI="multi"
# Extra command-line arguments to the worker
CELERYD_OPTS="--loglevel=INFO --time-limit=300 --concurrency=3"
# - %n will be replaced with the first part of the nodename.
# - %I will be replaced with the current child process index
# and is important when using the prefork pool to avoid race conditions.
CELERYD_PID_FILE="/var/run/celery/%n.pid"
CELERYD_LOG_FILE="/var/log/celery/%n%I.log"

# you may wish to add these options for Celery Beat
CELERYBEAT_PID_FILE="/var/run/celery/beat.pid"

还有应用程序文件：

sys.path.append(os.getcwd())

global logger
logger = create_rotating_log('./log/activity.log')

#logger.info('Celery session OK')
except Exception as e:
logger.error('Celery session KO')
logger.error(e)
if __name__ == '__main__':
