Installing Custom Packages in Apache Airflow

To install Apache Airflow management pack (mpack) for Python3.11 and RHEL8 with Postgres15, perform the following steps.

Download the Airflow mpack from the Mpacks Link.

Install Python3.11 and create symlinks:

sudo ln -sf /usr/bin/python3.11 /usr/bin/python3 sudo ln -sf /usr/bin/pip3.11 /usr/bin/pip3

Install and setup Postgres15:

sudo -u postgres psql CREATE DATABASE airflow; CREATE USER airflow WITH PASSWORD 'airflow'; ALTER ROLE airflow SET client_encoding TO 'utf8'; ALTER ROLE airflow SET default_transaction_isolation TO 'read committed'; ALTER ROLE airflow SET timezone TO 'UTC'; GRANT ALL PRIVILEGES ON DATABASE airflow TO airflow; \c airflow GRANT ALL ON SCHEMA public TO airflow; \q

Update PostgreSQL configuration files:

Edit /var/lib/pgsql/15/data/postgresql.conf:

vi /var/lib/pgsql/15/data/postgresql.conf

Uncomment the following lines:

listen_addresses = '*' port = 5432

Edit /var/lib/pgsql/15/data/pg_hba.conf:

vi /var/lib/pgsql/15/data/pg_hba.conf

Add the following line:

host airflow airflow 37.27.118.52/32 md5

Restart PostgreSQL:

sudo systemctl restart postgresql-15

Install google-re2 package and psycopg2-binary:

pip3 install psycopg2-binary pip3 install google-re2

If the package is not installed, download it and then install it. After running the below command, you will get a wheel package like google_re2-1.1.20240501-1-cp39-cp39-manylinux_2_24_x86_64.manylinux_2_28_x86_64.whl:

pip3 download google-re2

Info

Ensure that you have set up the repository for Airflow before proceeding with the Airflow service installation through Ambari.

Install Mpack:

ambari-server install-mpack --mpack=ambari-mpacks-airflow-2.8.3.tar.gz --verbose

Refer to the screenshots below for guidance on installing the service via Ambari UI:

Follow the Airflow configurations steps provided in the Apache Airflow Installation using Mpack on Ambari guide.

Access the Airflow UI using your Airflow credentials, in this case we are using 'airflow' as the username and password.
