我有一个使用 redis 集成 celery 的 django 项目。
我的 celery 工人在本地开发中完美地工作,现在我正在生产中进行部署。在守护进程之前,我想看看 celery 在服务器中的行为。问题是,celery beat 每分钟都正确发送任务(如我计划的那样),但工作人员似乎并非每次都收到它。有时需要 4/5 分钟才能收到并处理任务。这怎么可能?我试过调试,但信息很少。
查看我的设置:settings.py
CELERY_TIMEZONE = 'Europe/Warsaw'
CELERY_BROKER_URL = 'redis://localhost:6379'
CELERY_RESULT_BACKEND = 'redis://localhost:6379'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TASK_SERIALIZER = 'json'
# Other Celery settings
CELERY_BEAT_SCHEDULE = {
'task-number-one': {
'task': 'predict_assistance.alerts.tasks.check_measures',
'schedule': crontab(minute='*/1'),
},
}
任务.py
from __future__ import absolute_import, unicode_literals
from celery import shared_task
@shared_task()
def check_measures():
print('doing something')
芹菜.py
from __future__ import absolute_import, unicode_literals
import os
from celery import Celery
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'config.settings.local')
app = Celery('predict_assistance')
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks()
在此我的生产日志:
