How to Install Apache Kafka on Ubuntu 20.04

To install Apache Kafka on Ubuntu 20.04, follow these general steps:

1. Install Java

Kafka requires Java to run. You can install OpenJDK by running:

sudo apt update
sudo apt install default-jdk

2. Download Kafka

Visit the Apache Kafka downloads page to get the latest version. Use wget to download it:

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

3. Extract Kafka

Extract the downloaded Kafka archive:

tar -xzf kafka_2.13-2.8.0.tgz

4. Move Kafka

Move the extracted Kafka directory to /usr/local/kafka:

sudo mv kafka_2.13-2.8.0 /usr/local/kafka

5. Start Kafka Server

Kafka requires Zookeeper to run. Start Zookeeper and Kafka server using the following commands:

/usr/local/kafka/bin/zookeeper-server-start.sh /usr/local/kafka/config/zookeeper.properties
/usr/local/kafka/bin/kafka-server-start.sh /usr/local/kafka/config/server.properties

6. Create Kafka Topics

You can create a topic using:

/usr/local/kafka/bin/kafka-topics.sh --create --topic test --bootstrap-server localhost:9092 --partitions 1 --replication-factor 1

7. Run Producer and Consumer

Test your setup by running a producer and consumer:

/usr/local/kafka/bin/kafka-console-producer.sh --topic test --bootstrap-server localhost:9092
/usr/local/kafka/bin/kafka-console-consumer.sh --topic test --from-beginning --bootstrap-server localhost:9092
