Airflow 气流-D不工作，不在后台运行

我可以正常启动webserver，使用命令

airflow webserver

。但是当我使用

气流Web服务器-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。我使用命令

ps-ef | grep afflow

进行检查

气流的版本为

1.10.6

---

在以前的版本中，

-D

用于正常工作

如果您可以正常运行

airflow Web服务器

。气流Web服务器-D没有错误，并且找不到作为气流Web服务器运行的进程

必须是您杀死了

airflow webserver-D的后台进程，并且没有删除airflow webserver的pid文件

您可以转到
$afflow\u HOME/afflow
目录，检查pid文件。如果存在且不为空，请将其删除并重试：

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

你有没有发现任何错误？没有。如果开始时没有-D，这是正常的。很高兴和你一起深入研究这个问题，你是不是很放松？谢谢你的帮助。是的，我在上班。apache-airflow.slack.com
