The method for installing and deploying a Kafka cluster is as follows:

  1. Install Java Environment: Since Kafka is developed based on Java, it is necessary to install the Java environment first. You can download the Java JDK from the Oracle official website and follow the instructions for installation.
  2. Download Kafka: Download the latest Kafka release version from the official Apache Kafka website. You can choose between the binary version or the source code version.
  3. Unzip Kafka: Extract the downloaded Kafka compressed file to a specified directory.
  4. Configuring Kafka: Edit Kafka’s configuration file (config/server.properties) which includes several important configurations.
  5. broker.id: unique identifier for each Kafka node.
  6. Listeners: The address and port that Kafka is listening on.
  7. Directory where message storage occurs.
  8. Connect to the Zookeeper address.
  9. Modify these configurations as needed and save the file.
  10. Start Zookeeper: Kafka relies on Zookeeper to manage the state information of the cluster. The first step is to start the Zookeeper service. You can start Zookeeper by running the following command:
bin/zookeeper-server-start.sh config/zookeeper.properties
  1. Start Kafka cluster: Run the following command on each Kafka node to start the Kafka service.
bin/kafka-server-start.sh config/server.properties

The commands above can be run on different nodes to start multiple Kafka nodes, forming a Kafka cluster.

  1. To verify the Kafka cluster, you can use the command-line tools provided by Kafka to check the running status of the cluster. For example, you can use the following command to create a topic and send some messages.
bin/kafka-topics.sh --create --topic my-topic --zookeeper localhost:2181 --partitions 1 --replication-factor 1
bin/kafka-console-producer.sh --topic my-topic --broker-list localhost:9092
bin/kafka-console-consumer.sh --topic my-topic --from-beginning --bootstrap-server localhost:9092

The above is the basic method for installing and deploying Kafka clusters, which can be further adjusted based on specific needs and environment configurations.
