Question

当我启动带有某些队列的气流工作程序时，它会引发以下错误。

我已经在airflow配置中配置了数据库详细信息。但不确定为什么要尝试连接到本地mysql服务器

[2018-10-29 18:59:32,012: ERROR/MainProcess] Pool callback raised exception: OperationalError('(_mysql_exceptions.OperationalError) (2002, "Can\'t connect to local MySQL server through socket \'/var/lib/mysql/mysql.sock\' (2)")',)

OperationalError: (_mysql_exceptions.OperationalError) (2002, "Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)")

为什么Airflow Worker尝试连接到本地MYSQL服务器而不是从airflow配置中获取
