django通过celery定时任务

settings.py

# Broker配置，使用Redis作为消息中间件
BROKER_URL = 'redis://127.0.0.1:6379/0'

# BACKEND配置，这里使用redis
CELERY_RESULT_BACKEND = 'redis://127.0.0.1:6379/0'

# 结果序列化方案
CELERY_RESULT_SERIALIZER = 'json'

# 任务结果过期时间，秒
CELERY_TASK_RESULT_EXPIRES = 60 * 60 * 24

# 时区配置
CELERY_TIMEZONE = 'Asia/Shanghai'

# 指定导入的任务模块，可以指定多个
CELERY_IMPORTS = (
   'scriptOperate.tasks'
)

CELERYBEAT_SCHEDULE = {
    'ali_script': {
        # 任务路径
        'task': 'scriptOperate.tasks.get_ali_script_status',
        # 每日七点执行
        # 'schedule': crontab(hour=7, minute=0),
        'schedule': timedelta(seconds=20)
        # 'schedule':5
    },
    'log_file': {
            # 任务路径
            'task': 'scriptOperate.tasks.produce_log',
            # 每日零点执行
            'schedule': crontab(hour=0, minute=0),   # 通过crontab进行定时
        },
    'weather_file':{
            'task': 'scriptOperate.tasks.get_weather_status',
            'schedule': crontab(hour=7, minute=0)
            # 'schedule': timedelta(seconds=20)
    },
    'power_file':{
            'task': 'scriptOperate.tasks.get_power_status',
            'schedule': crontab(hour=5, minute=30),
            # 'schedule': timedelta(seconds=20)
    },
    'overview':{
                'task': 'scriptOperate.tasks.get_overview_status',
                'schedule': crontab(hour=7, minute=10),
                # 'schedule': timedelta(seconds=30)
        }
}

settings.py同级目录下创建celery.py

import os
import django
from celery import Celery
from django.conf import settings
from celery.schedules import crontab
# 设置系统环境变量，安装django，必须设置，否则在启动celery时会报错
# celery_study 是当前项目名
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'code_work2.settings')
# django.setup()

celery_app = Celery('scriptOperate')
celery_app.config_from_object('django.conf:settings')
celery_app.autodiscover_tasks(settings.INSTALLED_APPS)

在app下创建tasks.py

import logging
import json
import datetime
import time
import os.path
import re
import pysftp
from celery import shared_task
from log.log_files import Logger
from code_work2.celery import celery_app
from scriptOperate.task import ali_monitor, weather_monitor, power_monitor, over_view_monitor

# log = Logger('../log/files/data.log', level='debug')
# logger = log.logger

# @shared_task
@celery_app.task
def get_ali_script_status():
    ali_monitor.get_ali_status()

@celery_app.task
def get_weather_status():
    weather_monitor.get_weather_status()

@celery_app.task
def get_power_status():
    power_monitor.get_power_status()

@celery_app.task
def get_overview_status():
    over_view_monitor.get_overview_status()

@shared_task
def produce_log():
    Logger(logfile, level='debug')

启动任务

celery -A code_work2 beat -l info   启动beat
celery -A code_work2 worker -l info -P eventlet 启动celery
