Airflow安裝錯誤:sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError)

1 完整的異常信息：

raise errorclass, errorvalue
sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (1292, "Incorrect datetime value: '2019-10-18 13:41:07.937196+00:00' for column 'last_scheduler_run' at row 1") [SQL: u'UPDATE dag SET last_scheduler_run=%s, description=%s, schedule_interval=%s WHERE dag.dag_id = %s'] [parameters: (datetime.datetime(2019, 10, 18, 13, 41, 7, 937196, tzinfo=<Timezone [UTC]>), 'spark ETL ', '"55 00  * * *"', 'sparkEtl’)]

　　

2 安裝Airflow 執行 airflow initdb，遇到上面的錯誤

3 最后解決，Stack Overflow查到一條回答

mysql的模式問題
Just to recap for future users:
Stop the service:
systemctl stop mysql
Get the current state:
mysql> select @@sql_mode;
Add statement to the config without "STRICT_TRANS_TABLES":
sudo nano /etc/mysql/my.cnf
under [mysqld]:
sql_mode="paste "select @@sql_mode;" output **without** STRICT_TRANS_TABLES"
Then start the service again:
systemctl start mysql

4 最后解決，原來是自己的/etc/my.cnf中配置了

sql_mode='STRICT_TRANS_TABLES'

 

刪除上面的STRICT_TRANS_TABLES參數，重啟就ok了。如果這個配置和其他配置沖突，建議airflow安裝獨立的mysql。
