Installation¶
Getting Airflow¶
The easiest way to install the latest stable version of Airflow is with pip
:
pip install apache-airflow
You can also install Airflow with support for extra features like s3
or postgres
:
pip install apache-airflow[postgres,s3]
Extra Packages¶
The apache-airflow
PyPI basic package only installs what’s needed to get started.
Subpackages can be installed depending on what will be useful in your
environment. For instance, if you don’t need connectivity with Postgres,
you won’t have to go through the trouble of installing the postgres-devel
yum package, or whatever equivalent applies on the distribution you are using.
Behind the scenes, Airflow does conditional imports of operators that require these extra dependencies.
Here’s the list of the subpackages and what they enable:

Initiating Airflow Database¶
Airflow requires a database to be initiated before you can run tasks. If you’re just experimenting and learning Airflow, you can stick with the default SQLite option. If you don’t want to use SQLite, then take a look at Initializing a Database Backend to setup a different database.
After configuration, you’ll need to initialize the database before you can run tasks:
airflow initdb
