worker_concurrency配置对芹菜无效

Question

环境: Django3.1，celery5.2 Django setting.py

CELERY_RESULT_BACKEND = 'django-db'
CELERY_BROKER_URL = 'redis://127.0.0.1/0'
CELERYD_CONCURRENCY = 2  # 并发worker数
# CELERYD_PREFETCH_MULTIPLIER=1
CELERYD_FORCE_EXECV = True 
CELERYD_MAX_TASKS_PER_CHILD = 50  

celery.py

import os

from celery import Celery

# Set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'san.settings')

app = Celery('san')
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django apps.
app.autodiscover_tasks()

celery -A san worker -l INFO -P gevent：启动命令

-芹菜@dev.10.1.1.209 v5.2.3

- .>结果：

• *- .>并发:4 (gevent) -*- .>任务事件: OFF (使-E能够监视该工人的任务)-*

并发性: 4，为什么我的配置不生效？在启动命令中指定'-c‘参数是有效的。

• **

我能做些什么来使我的配置工作？

我的其他配置可以工作，如CELERY_BROKER_URL、CELERY_RESULT_BACKEND

Answer 1

# 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.

将CELERYD CONCURRENCY更改为CELERY_WORKER_CONCURRENCY
