Question

尝试从sqlite db过渡到postgresql（基于此处的指南：https://www.ryanmerlin.com/2019/07/apache-airflow-installation-on-ubuntu-18-04-18-10/），并在Web服务器用户界面的初始屏幕上出现蘑菇状云错误。

    response = self.full_dispatch_request()

查看网络服务器日志不会显示太多...

值得注意的一件事（因为这似乎是由于某种密码问题引起的）是，在尝试切换到postgres之前，我已经根据文档（https://airflow.apache.org/docs/stable/security.html#password设置了bycrpt密码。脚本在这里：

import airflow
from airflow import models, settings
from airflow.contrib.auth.backends.password_auth import PasswordUser

user = PasswordUser(models.User())
user.username = 'airflow'
user.email = 'myemail@co.org'
user.password = 'mypasword'

session = settings.Session()
session.add(user)
session.commit()
session.close()
exit()

有人知道这里可能发生什么或如何进一步调试吗？

重新运行我的用户/密码脚本可以解决此问题。

我认为这是从以前使用的sqllite数据库连接到对新的postgres服务器的更改。我想这是存储在气流后端数据库中的某个地方（不是气流的新手，所以不了解这些内部情况），并且由于我要切换后端，因此新后端没有此用户/身份验证信息，需要重新运行脚本才能导入气流包装并将新的用户名/密码写入其后端以能够使用密码登录（因为我的airflow.cfg使用auth_backend = airflow.contrib.auth.backends.password_auth）。

切换后端数据库时，Airflow Web服务器上的password_auth.py蘑菇云错误打开
