worker_concurrency 配置对 celery 无效

Question

环境：Django3.1、celery5.2 姜戈 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()

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

---------------- celery@dev.10.1.1.209 v5.2.3（黎明合唱） --- ***** ----- -- ******* ---- Linux-3.10.0-327.el7.x86_64-x86_64-with-glibc2.17 2022-02-18 14:31:44

*** --- * ---
** ---------- [配置]
** ---------- .> 应用程序：san:0x7f7d31a811c0
** ---------- .> 传输：redis://127.0.0.1:6379/0
** ---------- .> 结果：
*** --- * --- .> 并发数：4 (gevent) -- ******* ---- .> task events: OFF (enable -E to monitor tasks in this worker) --- ***** ----- -------------- [队列] .> celery exchange=celery(直接) key=celery

concurrency: 4,为什么我的配置没有生效？在启动命令中指定'-c'参数有效。

*** --- * --- .> 并发数：2 (gevent)

我该怎么做才能让我的配置生效？

我的其余配置有效，例如 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

worker_concurrency 配置对 celery 无效

worker_concurrency configuration not valid for celery

python

celery

django-celery
