Starting Kafka

At this point, Kafka has already been installed and all we have to do is start the service.

Step 1

Let first start the Zookeeper service. In a new terminal (Window > New terminal or Alt-T) run the following script.

./scripts/zookeeper-start.sh

Step 2

Next, let's start the Kafka service. In a new terminal (Window > New terminal or Alt-T) run the following script.

./scripts/kafka-start.sh

Tip: You can stop the services using the following commands:

./scripts/kafka-stop.sh

./scripts/zookeeper-stop.sh

Step 3

Let's try out Kafka. We will have a producer to send messages to a topic that a consumer will be reading.

Producer In a new terminal (Window > New terminal or Alt-T) run the following command:

Ignore any warnings

kafka_2.13-2.6.0/bin/kafka-console-producer.sh --topic quickstart-events --bootstrap-server localhost:9092

Consumer In a new terminal (Window > New terminal or Alt-T) run the following command:

Ignore any warnings

kafka_2.13-2.6.0/bin/kafka-console-consumer.sh --topic quickstart-events --from-beginning --bootstrap-server localhost:9092

We are now ready to broker messages. In the Producer terminal, type some text and press enter. In the Consumer terminal you should see your text getting read.
