In this tutorial, we will show you the complete steps to install Apache Kafka on Ubuntu 24.04 OS.

Step 1: Update Operating System

Update your Debian 12 operating system to make sure all existing packages are up to date:

# apt update && apt upgrade

Step 2: Install Java (OpenJDK) on Ubuntu 24.04

Java packages are available on Ubuntu 24.04 repositories and you can install it with the following command:

# apt install default-jdk

Check Java version after installation:

# java -version
openjdk version "21.0.6" 2025-01-21
OpenJDK Runtime Environment (build 21.0.6+7-Ubuntu-124.04.1)
OpenJDK 64-Bit Server VM (build 21.0.6+7-Ubuntu-124.04.1, mixed mode, sharing)

Step 3: Download Apache Kafka

Check the official Apache Kafka Download page to locate the latest version of the software.

The latest version at the moment is 4.0.0. You can download it with the following command:

# wget https://downloads.apache.org/kafka/4.0.0/kafka_2.13-4.0.0.tgz

Once that downloads, unpack the tarball file using the following command:

# tar xvf kafka_2.13-4.0.0.tgz

Then move this directory into the /usr/local/ directory and rename it kafka:

# mv kafka_2.13-4.0.0 /usr/local/kafka

Step 4: Create a systemd file for Apache Kafka

First navigate to Kafka’s directory:

# cd /usr/local/kafka

Then you need to generate a Cluster UUID:

# KAFKA_CLUSTER_ID="$(bin/kafka-storage.sh random-uuid)"

Format Log Directories:

# bin/kafka-storage.sh format --standalone -t $KAFKA_CLUSTER_ID -c config/server.properties

Now create a systemd file so you can control the Kafka service. Create the file with the following command:

# nano /etc/systemd/system/kafka.service

In that file, paste the following content:

[Unit]
Description=Apache Kafka Server
Documentation=http://kafka.apache.org/documentation.html
Requires=zookeeper.service

[Service]
Type=simple
Environment="JAVA_HOME=/usr/lib/jvm/java-1.21.0-openjdk-amd64"
ExecStart=/usr/local/kafka/bin/kafka-server-start.sh /usr/local/kafka/config/server.properties
ExecStop=/usr/local/kafka/bin/kafka-server-stop.sh

[Install]
WantedBy=multi-user.target

Save the changes and exit.

Reload system daemon and start the services:

# systemctl daemon-reload
# systemctl start kafka
# systemctl enable kafka

To confirm everything is working normally, check the status of service:

# systemctl status kafka

Output:

● kafka.service - Apache Kafka Server
     Loaded: loaded (/etc/systemd/system/kafka.service; enabled; preset: enabled)
     Active: active (running)
       Docs: http://kafka.apache.org/documentation.html
   Main PID: 11915 (java)
      Tasks: 99 (limit: 2217)
     Memory: 365.1M (peak: 365.4M)
        CPU: 16.435s
     CGroup: /system.slice/kafka.service

Step 5: Create a Kafka Topic

So before you can write your first events, you must create a topic. Create a topic named “my-events” with the following command:

# usr/local/kafka
# bin/kafka-topics.sh --create --topic my-events --bootstrap-server localhost:9092

Created topic my-events.

To verify the topic list run the following command:

# bin/kafka-topics.sh --list --bootstrap-server localhost:9092
my-events

The Kafka comes with a command-line client that will take input from a file or from standard input and send it out as events to the Kafka cluster.

By default, each line you enter will result in a separate event being written to the topic.

# bin/kafka-console-producer.sh --topic my-events --bootstrap-server localhost:9092

>Hello World!
>This is my first topic

You can stop the consumer client with Ctrl-C at any time.

If you also want to delete any data of your local Kafka environment including any events you have created along the way, run the command:

# rm -rf /tmp/kafka-logs /tmp/kraft-combined-logs

Comments and Conclusion
