Airflow添加用户登录

通常我们部署airflow调度系统的时候，默认是直接以admin用户登录进来的，而且不需要输入账号密码

如果业务要求必须通过不同的用户登录进来，可以采用以下的方法给airflow添加用户

在 airflow.cfg 文件中 [webserver] 下添加如下配置

[webserver]
authenticate = True
auth_backend = airflow.contrib.auth.backends.password_auth

在这里提醒一下，authenticate这个配置项在配置文件里面很多地方都有，非常容易配错了，如果配置错了，很容易掉坑里

个人建议先在配置文件找到[webserver]，然后直接添加内容，然后保存退出

接下来通过命令行添加用户，我这里的airflow是部署在容器里面的，先进入airflow所在的容器，如果部署在服务器上就直接在服务器里执行

以下是添加用户的命令

python

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

user = PasswordUser(models.User())
user.username = 'usertest1'
user.email = 'usertest1@163.com'
user.password = 'usertest1'
user.superuser = 1 //赋予管理员权限，如果是普通用户就不需要这个

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

考虑到现在新的airflow版本用的是python3,在执行语句

from airflow.contrib.auth.backends.password_auth import PasswordUser

的时候会报错，大概也是是没有对应的包，可以通过    pip install  包名    来下载对应的依赖包。

下面是具体例子

然后重启一下web，进入浏览器

点击右上角的退出

这个时候就可以通过用户名密码登录了！！
