Celery 服务活动：不活动（死） - Systemd，为什么它没有启动？

我已将 celery 设置为 systemd这里提到。

我的芹菜服务

WantedBy=multi-user.target

我的/etc/conf.d/celery

# Name of nodes to start
# here we have a single node
CELERYD_NODES="w1"
# or we could have three nodes:
#CELERYD_NODES="w1 w2 w3"

# Absolute or relative path to the 'celery' command:
#CELERY_BIN="/usr/local/bin/celery"
CELERY_BIN="/root/venv/bin/celery"

# App instance to use
# comment out this line if you don't use an app
CELERY_APP="project"
# 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="--time-limit=300 --concurrency=8"

# - %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"
CELERYD_LOG_LEVEL="INFO"

现在，当我通过输入启动 celery 时，sudo service celery start我收到以下响应

● celery.service - Celery Service

我哪里错了？

ps：我在安装 celery 时遇到了很多问题，认真考虑不使用它，因为它很复杂而且文档没有帮助。我应该使用其他替代方案吗？
