Airflow【部署 01】Airflow官网Quick Start实操（一篇学会部署Airflow）_apache airflow教程

1.环境变量设置

Airflow需要一个主目录，默认使用~/airflow，但如果您喜欢，可以设置一个不同的位置。AIRFLOW_HOME环境变量用于通知Airflow所需的位置。设置环境变量的这一步应该在安装Airflow之前完成，以便安装过程知道在哪里存储必要的文件。

export AIRFLOW\_HOME=~/airflow

2.使用约束文件进行安装

官网给出的文件内容：

AIRFLOW\_VERSION=2.7.2

# Extract the version of Python you have installed. If you're currently using a Python version that is not supported by Airflow, you may want to set this manually.
# See above for supported versions.
PYTHON\_VERSION="$(python --version | cut -d " " -f 2 | cut -d "." -f 1-2)"

CONSTRAINT\_URL="https://raw.githubusercontent.com/apache/airflow/constraints-${AIRFLOW\_VERSION}/constraints-${PYTHON\_VERSION}.txt"
# For example this would install 2.7.2 with python 3.8: https://raw.githubusercontent.com/apache/airflow/constraints-2.7.2/constraints-3.8.txt

pip install "apache-airflow==${AIRFLOW\_VERSION}" --constraint "${CONSTRAINT\_URL}"

本次使用虚拟环境进行安装：

# 创建并切换到airflow虚拟环境
conda create -n airflow python=3.8
conda activate airflow

创建约束文件airflowInstall.sh添加官网给出的内容：

AIRFLOW\_VERSION=2.7.2
PYTHON\_VERSION="$(python --version | cut -d " " -f 2 | cut -d "." -f 1-2)"
CONSTRAINT\_URL="https://raw.githubusercontent.com/apache/airflow/constraints-${AIRFLOW\_VERSION}/constraints-${PYTHON\_VERSION}.txt"
pip install "apache-airflow==${AIRFLOW\_VERSION}" --constraint "${CONSTRAINT\_URL}"

执行文件即可。也可以使用pip
