How To Install Apache Kafka on Ubuntu 20.04
If you wish to install Apache Kafka on Ubuntu 20.04, you have reached the proper place. Apache Kafka is a well-known open-source messaging technology that is utilized by several developers to construct real-time data pipelines and streaming applications. In this article, we will demonstrate how to install Apache Kafka on Ubuntu 20.04 step by step.
Step 1: Install Java
Ensure that Java is already installed on your Ubuntu 20.04 system before installing Apache Kafka. Running Apache Kafka requires Java 8 or later. Use the following command to install Java on your Ubuntu 20.04 system:
sudo apt update
sudo apt install default-jre
After the installation is complete, the following command can be executed to confirm that Java has been installed:
java -version
This will display the version of Java installed on your system.
Step 2: Download and Extract Kafka
Download and extract the Apache Kafka binaries as the next step. Follow these steps to achieve this:
- Visit the Apache Kafka website and obtain the most recent stable release.
- Start a terminal window and navigate to the directory where the Kafka binary was downloaded.
- Run the command listed below to extract the Kafka binary:
tar -xzf kafka_2.13-2.8.0.tgz
This will extract the Kafka binary to a folder named kafka_2.13-2.8.0.
Step 3: Start the Kafka Server
Now that Kafka has been installed on your system, it is time to launch the Kafka server. Follow the instructions below:
- Go to the Kafka binary directory:
cd kafka_2.13-2.8.0
- Run the command below to launch the Kafka server:
bin/kafka-server-start.sh config/server.properties
This begins the Kafka server on your system.
Step 4: Create a Topic
Now that the Kafka server is operational, a topic must be created. Follow the instructions below:
- Launch a new terminal window and navigate to the Kafka binary directory.
- Use the command below to create a new topic:
bin/kafka-topics.sh --create --topic test-topic --bootstrap-server localhost:9092
This will create a new topic named test-topic on the Kafka server.
Step 5: Send and Receive Messages
Now that you’ve created a topic, you can send and receive messages. Follow the instructions below:
- Launch a new terminal window and navigate to the Kafka binary directory.
- Use the command below to launch a console producer:
bin/kafka-console-producer.sh --topic test-topic --bootstrap-server localhost:9092
This will start a console producer that allows you to send messages to the test-topic topic.
- Use the following command in a new terminal window to start a console consumer:
bin/kafka-console-consumer.sh --topic test-topic --from-beginning --bootstrap-server localhost:9092
This will start a console consumer that allows you to receive messages from the test-topic topic.
Now you can start sending and receiving messages between the console producer and consumer. To send a message, type it into the console producer window and hit Enter. The message will be sent to the test-topic topic and will be received by the console consumer window.
Conclusion
This article describes how to install Apache Kafka on Ubuntu 20.04 step by step. In addition, we have demonstrated how to construct a topic, send and receive messages using the console producer and consumer. You are now prepared to begin developing real-time data pipelines and streaming applications with Apache Kafka.
