Running Kafka Worker Process as a Service on Linux

Are you currently using a terminal session on your Linux server to run a Kafka worker process? If so, you might have faced the dilemma of wanting to leave your terminal without interrupting the operation of your services. It’s a common scenario for many users, and you’re not alone in wondering how to run your Kafka worker process as a service. In this guide, we will explore the best approaches to achieve a seamless execution of Kafka worker processes, allowing you to continue working on other tasks without worrying about disconnecting your session.

Why Service Mode is Preferred

Running your Kafka worker in standalone mode can be convenient for development or testing, but it's not an ideal choice for production. The standalone mode does not support automatic recovery from failures, and it requires you to manually restart your worker processes. On the other hand, operating in service mode can enhance reliability and ensure your Kafka instance stays live and responsive.

Two Approaches to Running Kafka Worker

There are two primary methods to run your Kafka worker process as a service on a Linux system: using the screen utility for a quick-and-easy method, and setting it up as a systemd service for a more robust solution.

Method 1: Using Screen Utility

If you want to keep things simple and don’t want to create a full-fledged service, using the screen utility can be an effective temporary solution.

Steps to Use Screen

Create a Screen Session

Exit the Screen Session
Inside the active screen, type exit to terminate the terminal session.

This method is great for short-term needs but may not be the most efficient for long-term operations.

Method 2: Creating a Systemd Service

For a more permanent and reliable solution, configuring Kafka to run as a service is the way to go. This allows the worker processes to start on system boot and ensures more effective management.

Steps to Create a Systemd Service

Create the Service File
Create a new file named kafka-connect.service in the /etc/systemd/system directory.

Add the Following Configuration

Modify as Necessary

The ExecStart line incorporates the command to start Kafka in distributed mode.

If you have not installed the jmx_exporter, feel free to remove the specific KAFKA_OPTS line from the service file.

Enable and Start the Service
After saving the file, execute the following commands:

Conclusion

Running your Kafka worker process as a service not only helps in maintaining persistence but also simplifies management over time. The method you choose will depend on your specific needs and the environment you're working within. Whether you opt for the quick fix using the screen utility or configure it as a systemd service for greater reliability, you now have the tools and knowledge to keep your Kafka workers operating smoothly.
