To install Apache Kafka on Ubuntu, follow these steps:
1. Install the Java runtime environment (Ubuntu):
If you have installed jdk do not need to execute
sudo apt update
sudo apt install default-jre
2. Download Kafka:
wget https://downloads.apache.org/kafka/3.5.1/kafka_2.12-3.5.1.tgz
3. Unzip the downloaded file:
tar -xzf kafka_2.12-3.5.1.tgz
4. Enter the Kafka directory:
cd kafka_2.12-3.5.1
5. Start the Zookeeper server. Execute the following command in a separate terminal window:
bin/zookeeper-server-start.sh config/zookeeper.properties
root@ubuntu2203:/usr/local/kafka_2.12-3.5.1# bin/zookeeper-server-start.sh config/zookeeper.properties

Kafka is now successfully installed and running locally.
Note: By default, Kafka uses the local file system for message storage and log storage. If you wish to modify the configuration, edit config/server.propertiesthe file to make the appropriate changes.
If you need to create a topic (topic), send a message, consume a message, etc., please refer to the official documentation of Kafka for corresponding configuration and use.
