Airflow 2.8.0中Celery Worker的broker_url配置位置及默认文件咨询

问题1：broker_url 配置项的放置位置 #

Airflow 2.x 版本（含2.8.0）已将Celery相关配置整合到主配置文件**airflow.cfg**中，无需去airflow.providers.celery目录寻找单独配置文件——你看到的旧文档内容已过时。

若你的airflow.cfg中没有[celery]配置段，直接手动添加即可，将broker_url置于该段落下：

[celery]
broker_url = redis://你的Redis地址:6379/0
# 可补充其他Celery相关配置示例：
# result_backend = db+postgresql://airflow_user:密码@localhost:5432/airflow_db
# worker_concurrency = 16

问题2：Celery Worker 默认使用的配置文件 #

Airflow Celery Worker 默认直接读取**airflow.cfg**中的Celery配置段。你启动日志里显示的redis://redis:6379/0是Airflow内置的默认Broker URL值——当未手动配置broker_url时，Worker会自动使用该默认值连接Redis。

你提供的启动日志： #
