在 django celery 節拍中收到任務，但未執行

Question

我正在使用 django 和 celery、celery 節拍和 Z86A1B907D54BF7010394BF316E183 運行周期性任務。

我遇到的問題是在 celery 中注冊的任務已收到但未執行。

此外，即使我沒有指定停止設置，任務也會在中間停止。

環境如下。

windows10
python = 3.7.9
PostgreSQL 13.3
Redis server v=3.0.504 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=a4f7a6e86f2d60b3
[requirements]
celery==5.0.5
Django==3.2.4
django-celery-beat==2.2.0
django-celery-results==2.0.1
django-redis==5.0.0
redis==3.5.3

我通過參考以下站點構建了環境。

https://docs.celeryproject.org/en/stable/django/first-steps-with-django.html

project

+-app
|   +-__init__.py
|   +-tasks.py
|
+-project
|   +-__init__.py
|   +-celery.py
|   +-settings.py
|
+-.env
+-manage.py
+-requirements.txt

設置配置如下。

設置.py

INSTALLED_APPS = [ 
    # Add your apps here to enable them 
.

    'django_celery_beat',

# Database

load_dotenv(find_dotenv()) 
DATABASES = { 
    'default': dj_database_url.config(conn_max_age=600), 
}

CELERY_BROKER_URL = "redis://127.0.0.1:6379/1" 
CELERY_RESULT_BACKEND = "django-db" 
#CELERY_RESULT_BACKEND = "redis://127.0.0.1:6379/" 
DEFAULT_AUTO_FIELD = 'django.db.models.AutoField' 
CELERY_BEAT_SCHEDULER = 'django_celery_beat.schedulers:DatabaseScheduler'

.env

DATABASE_URL=postgres://postgres:pass@localhost/project

celery.py

import os 
from celery import Celery 
# set the default Django settings module for the 'celery' program. 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 
                      'Project.settings') 
app = Celery('Project') 
# 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') 
# Load task modules from all registere 
app.autodiscover_tasks() 
@app.task(bind=True) 
def debug_task(self): 
    print(f'Request: {self.request!r}')

項目/項目/初始化.py

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from celery import app as celery_app


__all__ = ('celery_app',)

項目/應用程序/tasks.py

from celery import shared_task


@shared_task 
def hello(): 
    print("hello")

project/app/ init .py 這是空的

(1) 我們做了什么

在瀏覽器的管理設置中，將 hello() 任務設置為每 5 秒永久運行一次。

(2) 我做了什么

在命令提示符下運行 redis 服務器：redis-server

在此環境下，使用 PowerShell 在項目根目錄下運行以下命令運行 celery worker

celery -A StreamerMonitoringWebsite worker -l info

另外，在另一個 Powershell 中運行以下命令來運行 celery beat

celery -A StreamerMonitoringWebsite beat --scheduler django_celery_beat.schedulers:DatabaseScheduler

（結果）

redis 和 celery 節拍仍在運行，並且沒有 output 任何日志。

管理站點的結果中也沒有留下任何日志。

celery worker output 以下日志。

我在哪里以及如何重寫它，以便它可以作為重復任務運行？

如果您需要比這些更多的信息來解決我的問題，請告訴我您想要哪些信息。

【附錄】

當我敢在beat中注冊一個拼寫錯誤的任務時，我在管理屏幕上得到了一個失敗的結果。

此外，如果您使用“--loglevel=INFO”運行 beat，您將看到任務正在以指定的頻率發送。

另一方面，工作人員接收已刪除的任務，就好像它已被緩存一樣。

1OK：我檢查了說它是從beat發送的日志。

2OK：錯誤的任務注冊了結果。

?1：redis 是否正確接收數據？

?2&3：redis 是否正確分配數據？

?4：為什么worker沒有執行任務？

Answer 1

celery -A 項目工作者 --loglevel=INFO --without-gossip --without-mingle --without-heartbeat -Ofair --pool=solo

Answer 2

在代碼后添加 --pool=solo 以啟動 celery 工作服務器

celery -A 任務工作者 --loglevel=INFO --pool=solo
