python django celery systemd

Question

我正在尝试为多个服务构建一个NGINX/Gunicorn/Celery/RabbitMQ/Django服务器。我未能为芹菜做废钞。

我的项目目录下面，其中芹菜安装在 virtualenv 中：

home/ubuntu/fanvault/bin/fanVault

我在下面的配置文件在/etc/conf.d/celery

CELERYD_NODES="w1 w2 w3"
CELERY_BIN="home/ubuntu/fanvault/bin/celery"
CELERY_APP="fanvault"
CELERYD_MULTI="multi"
CELERYD_OPTS="--time-limit=300 --concurrency=8"
CELERYD_PID_FILE="/var/run/celery/%n.pid"
CELERYD_LOG_FILE="/var/log/celery/%n%I.log"
CELERYD_LOG_LEVEL="INFO"

我的芹菜服务在 etc/systemd/system/

[unit]
Description=Celery Service
After=network.target
[Service]
Type=forking
User=ubuntu
Group=ubuntu
EnvironmentFile=-/etc/conf.d/celery
WorkingDirectory=/home/ubuntu/fanvault/bin/fanvault/fanvault/
ExecStart=/home/ubuntu/fanvault/bin/python3.5 -c '${CELERY_BIN} multi start ${CELERYD_NODES}  -A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE}  --logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'
ExecStop=/home/ubuntu/fanvault/bin/python3.5 -c '${CELERY_BIN} multi stopwait ${CELERYD_NODES}  --pidfile=${CELERYD_PID_FILE}'
ExecReload=/home/ubuntu/fanvault/bin/python3.5 -c '${CELERY_BIN} multi restart ${CELERYD_NODES}  -A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE}  --logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'
[Install]
WantedBy=multi-user.target

我在 home/ubuntu/fanvault/bin/fanvault/fanvault 中的 celery.py 文件

from __future__ import absolute_import, unicode_literals
import os
from celery import Celery
from datetime import timedelta
from fanvault.settings import DEBUG
if DEBUG is True:
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "fanvault.local_settings")
else:
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "fanvault.aws_settings")
app = Celery('fanvault')
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks()
app.conf.beat_schedule = {
    'pull_movie_home': {
        'task': 'movies.tasks.pull_movie_explore',
        'schedule': timedelta(minutes=3)
    }
}
app.conf.timezone = 'UTC'

当我执行"sudo 服务芹菜启动"时收到以下错误：

芹菜服务作业失败，因为控制进程退出并显示错误代码。有关详细信息，请参阅 "systemctl status celery.service" 和 "journalctl -xe"。

当我做"sudo journalctl -xe"时，得到以下信息：

Answer 1

我不确定为什么要将 Celery 启动命令传递给服务文件中的 Python3。这些是 shell 命令，要直接执行。
