Django-芹菜4.1配Django芹菜节拍/拉比问:没什么

Question

我遵循了http://docs.celeryproject.org/en/latest/我在virtualbox(Xubuntu 16.XX TLS)上，Django 1.11.3，Celery 4.1.rabbitmq3.6.14，Python 2.7.

当我用init脚本启动守护进程时：celeybeat(带有/etc/default/celeryd配置文件)

〔2017-11-19 01:13:00912:INFO/MainProcess〕节拍：正在启动。。。

之后没有其他内容。你知道我做错了什么吗？

我的简历.py:

from __future__ import absolute_import, unicode_literals
import os
from celery import Celery
# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'oscar.settings')
app = Celery('oscar')
# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')
# Broker settings
app.conf.broker_url = 'amqp://oscar:oscar@localhost:5672/oscarRabbit'
# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

我运行的启动命令(及其消息)：

使用配置：/etc/default/celeryd
正在启动celeybeat。。。

sudo /etc/init.d/celerybeat start

感谢您的回答

看起来您已经启动了celerybeat进程和服务器，但还没有启动芹菜worker进程。

python celery -A proj worker -B

(其中proj是项目的名称)。

请注意，您可以使用嵌入的beat进程启动celenicworker，而不需要单独运行celerybeat。
