Why Execute Apache Airflow on a Remote Server?
Before we dive into the nitty-gritty, let’s talk about why executing Apache Airflow on a remote server is a good idea. Here are just a few benefits:
- Scalability**: Running Apache Airflow on a remote server allows you to scale your workflows to meet the demands of your growing organization.
- Flexibility**: With a remote server, you can access your Apache Airflow instance from anywhere, at any time, making it perfect for teams working remotely.
- Security**: By hosting Apache Airflow on a remote server, you can ensure that your workflows and data are protected by robust security measures.
- Collaboration**: Multiple users can access and manage workflows on a remote server, making it easier to collaborate and streamline processes.
Prerequisites
Before we begin, make sure you have the following:
- A remote server with a supported operating system (e.g., Ubuntu, CentOS, or Amazon Linux)
- A basic understanding of Linux commands and terminal navigation
- Apache Airflow installed on your local machine (if you haven’t installed it yet, check out our Apache Airflow Installation Guide)
Step 1: Setting Up the Remote Server
Let’s start by setting up the remote server. This will involve installing the necessary dependencies and configuring the server to run Apache Airflow.
Installing Dependencies
Connect to your remote server using a Secure Shell (SSH) client like PuTTY or the built-in SSH terminal in your operating system. Once connected, run the following commands to install the required dependencies:
sudo apt-get update
sudo apt-get install -y python3-pip python3-dev
sudo pip3 install --upgrade pip
Configuring the Remote Server
Create a new user and group for Apache Airflow, and set up the necessary permissions:
sudo useradd airflow
sudo groupadd airflow
sudo usermod -aG airflow airflow
sudo chown -R airflow:airflow /usr/local/airflow
Step 2: Installing Apache Airflow on the Remote Server
Now that the remote server is set up, it’s time to install Apache Airflow:
sudo pip3 install apache-airflow
Wait for the installation to complete. This might take a few minutes, depending on your server’s processing power and internet connection.
Step 3: Configuring Apache Airflow on the Remote Server
Configure Apache Airflow by creating a new configuration file:
sudo airflow cfg init
Edit the `airflow.cfg` file to update the configuration settings:
sudo nano /usr/local/airflow/airflow.cfg
Update the following settings:
| Setting | Value |
|---|---|
| dag_folder | /usr/local/airflow/dags |
| plugins_folder | /usr/local/airflow/plugins |
| backend | mysql |
| sql_alchemy_conn | mysql://airflow:airflow@localhost:3306/airflow |
Step 4: Starting Apache Airflow on the Remote Server
Start the Apache Airflow web server and scheduler:
sudo airflow db init
sudo airflow webserver --port 8080
sudo airflow scheduler
Open a new terminal window and navigate to http://your-remote-server-ip:8080 to access the Apache Airflow web interface.
Step 5: Securing Apache Airflow on the Remote Server
Secure your Apache Airflow instance by configuring authentication and authorization:
Configuring Authentication
Edit the `airflow.cfg` file and update the authentication settings:
sudo nano /usr/local/airflow/airflow.cfg
Update the following settings:
| Setting | Value |
|---|---|
| auth_backend | airflow.contrib.auth.backends.password |
| webserver.auth_basic | true |
Creating Users and Roles
Create a new user and assign roles using the following commands:
sudo airflow create_user --username admin --password password --firstname Admin --lastname User --email [email protected] --role Viewer,Op,Admin
sudo airflow create_role --name Viewer
sudo airflow create_role --name Op
Conclusion
And that’s it! You’ve successfully executed Apache Airflow on a remote server. You can now access your Apache Airflow instance from anywhere, manage your workflows, and collaborate with your team.
Remember to regularly update and maintain your Apache Airflow instance to ensure optimal performance and security.
