Question

我可以使用命令airflow webserver正常启动Web服务器。但是当我使用airflow webserver -D时，它显示：

/data/software/miniconda3/lib/python3.7/site-packages/airflow/config_templates/airflow_local_settings.py:65: DeprecationWarning: The elasticsearch_host option in [elasticsearch] has been renamed to host - the old setting has been used, but please update your config.

然后，以后没有任何进程在后台运行。我用命令ps -ef|grep airflow检查。

Airflow的版本为1.10.6。

在以前的版本中，-D可以正常工作

如果您可以正常运行airflow webserver。 airflow webserver -D没有错误，并且您找不到作为气流Web服务器运行的进程。

一定是您杀死了airflow webserver -D的后台进程，并且您没有删除气流Web服务器的pid文件。

您可以转到$AIRFLOW_HOME/airflow目录，检查pid文件。如果存在但不为空，请将其删除并重试：

cd $AIRFLOW_HOME/airflow
rm airflow-webserver*.pid
airflow webserver -D

气流-D不起作用，不在后台运行
