我是靠谱客的博主妩媚火车，这篇文章主要介绍airflow从零开始部署，现在分享给大家，希望可以做个参考。

创建目录

mkdir /data/airflow

cd /data/airflow

下载并安装python

wget https://www.python.org/ftp/python/3.7.7/Python-3.7.7.tgz

tar -zxvf Python-3.7.7.tgz

cd Python-3.7.7

./configure --with-zlib #重要

make && make install

export AIRFLOW_HOME=/data/airflow

pip3 install apache-airflow

airflow initdb

修改 /data/airflow/airflow.cfg

sql_alchemy_conn = mysql+pymysql://root:xxx@127.0.0.1:3306/airflow

executor = CeleryExecutor

需安装Celery pip3 install celery

broker_url = redis://127.0.0.1:6379/3
celery_result_backend = redis://127.0.0.1:6379/4

result_backend = db+mysql+pymysql://root:xxx@127.0.0.1:3306/airflow

#启用web验证

[webserver]

authenticate = True
auth_backend = airflow.contrib.auth.backends.password_auth

需先部署mysql,启动会报错需安装pymysql

pip3 install pymysql

需安装redis服务器，redis客户端

pip3 install redis

启动

复制代码

>>> user.password = 'set_the_password'
>>> session = settings.Session()
>>> session.add(user)
>>> session.commit()
>>> session.close()
>>> exit()
