Installing Apache Kafka on Ubuntu: A Step-by-Step Guide

Apache Kafka is a powerful distributed streaming platform for building real-time data pipelines, messaging systems, and more. Ubuntu offers a great foundation to set up your Kafka installation if you’re working with large-scale data in a Linux environment. Let’s walk through the process step by step.

Prerequisites

• Ubuntu Server: I’ll assume you have an Ubuntu server ready (Ubuntu 20.04 or later is recommended).
• Java: Kafka is built on Java, so you’ll need a compatible Java Development Kit (JDK) installed. OpenJDK 11 is a good choice.
• Basic Command-Line Familiarity: You’ll use the command line for this process.

Step 1: Install Java

1. Update your package lists:
2. Bash
3. sudo apt update 
4. Use code.
5. content_copy
6. Install OpenJDK 11:
7. Bash
8. sudo apt install default-JDK
9. Use code 
10. content_copy
11. Verify installation:

Bash

java -version

Use code 

content_copy

Step 2: Create a Kafka User

• It’s best practice to run Kafka under a dedicated user for security. Create one:
• Bash
• sudo adduser Kafka
• Use code
• content_copy
• Give this user a password when prompted.

Step 3: Download Kafka Binaries

1. Visit the Apache Kafka downloads page: 
2. Choose the latest stable release and find the link for the binary tarball (.tgz file).
3. Right-click on the link and select “Copy Link Address”.
4. On your Ubuntu server, use wget to download:
5. Bash
6. wget <paste the copied download link>
7. Use code.
8. content_copy

Step 4: Extract and Organize

1. Extract the downloaded file:
2. Bash
3. tar -xzf kafka_*.tgz 
4. Use code 
5. content_copy
6. (Replace the filename with the actual downloaded file name)
7. Move the extracted directory to /opt:
8. Bash
9. sudo mv kafka_* /opt/kafka
10. Use code 
11. content_copy

Step 5: Configure Kafka

1. Navigate to Kafka’s configuration directory:
2. Bash
3. cd /opt/kafka/config/ 
4. Use code 
5. content_copy
6. Edit server.properties (use your preferred editor like Nano or Vim):
7. Bash
8. sudo nano server.properties
9. Use code 
10. content_copy
11. Modify at least the following settings:

• • listeners: Your server’s IP address and port (e.g., listeners=PLAINTEXT://192.168.1.10:9092)
  • log. Dirs: Where Kafka will store data (e.g., /var/log/kafka) – create this directory if needed.

Step 6: Systemd Unit Files

1. Create systemd service files for both Zookeeper (Kafka’s dependency) and Kafka:
2. Bash
3. sudo nano /etc/systemd/system/zookeeper.service
4. sudo nano /etc/systemd/system/kafka.service
5. Use code 
6. content_copy
7. Paste the respective configurations (find templates on resources like DigitalOcean tutorials).

Step 7: Start and Test

1. Reload system:
2. Bash
3. sudo systemctl daemon-reload
4. Use code 
5. content_copy
6. Start Zookeeper:
7. Bash
8. sudo systemctl start zookeeper
9. Use code 
10. content_copy
11. Start Kafka:
12. Bash
13. sudo systemctl start kafka
14. Use code 
15. content_copy
16. Verify both are running:
17. Bash
18. sudo systemctl status zookeeper
19. sudo systemctl status kafka
20. Use code 
21. content_copy

Congratulations! You’ve successfully installed Kafka on Ubuntu.
