2、安装MySQL（存在则略过）

1# 安装后创建airflow数据库
CREATE DATABASE airflow;

2# 修改配置文件  vi /etc/my.cnf 加入一行

[mysqld]
explicit_defaults_for_timestamp=1

或者在数据库命令行运行
set @@global.explicit_defaults_for_timestamp=on;

3、安装python3包

pip3 install --upgrade pip
pip3 install pymysql
pip3 install airflow
pip3 install paramiko

4、安装airflow依赖环境

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

5、在/etc/profile中末尾配置airflow环境变量

　　#airflow
　　export AIRFLOW_HOME=/software/airflow

6、初始化

airflow initdb

如果失败,则用

airflow db init

成功后则会在/software/airflow/目录下生成文件

airflow.cfg 

airflow.db 

logs 

unittests.cfg 

webserver_config.py

7、创建登录用户：

(venv) [root@localhost airflow]# airflow users create --username admin --firstname admin --lastname admin --role Admin --email xxx@163.com

回车提示输入密码

看到如下提示，则创建成功

Password:
Repeat for confirmation:
[2022-03-17 08:27:44,763] {manager.py:214} INFO - Added user admin
User "admin" created with role "Admin"

 8、启动airflow

airflow webserver
airflow scheduler

默认启动服务器localhost，默认端口8080，
如需修改服务器ip和端口，打开文件/software/airflow/airflow.cfg
修改host、port
