How to Install Apache Kafka on Elementary OS Latest

Apache Kafka is an open-source distributed event streaming platform that is used to manage, process, and analyze high volumes of data in real-time. Elementary OS is a lightweight and fast Linux distribution based on Ubuntu.

This tutorial will guide you on how to install Apache Kafka on Elementary OS Latest using Terminal commands.

Prerequisites

• A running instance of Elementary OS Latest
• Internet connection
• Terminal access with sudo privileges

Step 1: Update System Packages

Before installing Kafka, it is recommended to update the existing packages on your system. Open the Terminal and run the following command:

sudo apt-get update

Enter your sudo password when prompted and wait for the update process to complete.

Step 2: Install Java

Apache Kafka requires Java to be installed on the system. Run the following command to install Java:

sudo apt-get install default-jre

Type 'Y' when prompted to confirm the installation.

Step 3: Download Apache Kafka

Go to the official Apache Kafka website http://kafka.apache.org/downloads and download the latest stable version of Kafka. Alternatively, you can copy and paste the following command into the Terminal to download Kafka:

sudo wget https://downloads.apache.org/kafka/{VERSION_NUMBER}/kafka_{VERSION_NUMBER}.tgz

Replace {VERSION_NUMBER} in the above command with the version number of Kafka you want to install. For example:

sudo wget https://downloads.apache.org/kafka/2.8.0/kafka_2.13-2.8.0.tgz

Step 4: Extract Kafka

After downloading the Kafka tarball, extract it using the following command:

sudo tar -xzf kafka_{VERSION_NUMBER}.tgz

Again, replace {VERSION_NUMBER} with the actual version of Kafka you have downloaded.

Move to the extracted Kafka directory:

sudo mv kafka_{VERSION_NUMBER} /usr/local/kafka

Step 5: Configure Kafka

Before running Kafka, some configurations need to be set up. Navigate to the Kafka directory:

cd /usr/local/kafka/

Open the Kafka server properties file:

sudo nano config/server.properties

Find the line that starts with "#listeners" and remove the "#" at the beginning of the line. Then change the IP address to 0.0.0.0:

listeners=PLAINTEXT://0.0.0.0:9092

Save the changes and exit the editor.

Step 6: Run Kafka Sever

After configuring Kafka, start the Kafka server using the following command:

sudo bin/kafka-server-start.sh config/server.properties

Kafka will now start running on your system.

Conclusion

In this tutorial, we have successfully installed and configured Apache Kafka on Elementary OS Latest. You can now start developing applications that use Kafka for handling real-time data processing.
