Apache Kafka is a distributed streaming platform that allows you to publish and subscribe to messages in real time. In this tutorial, you will learn how to install Kafka on OpenSUSE.
Before you start, make sure you have the following:
The first step is to download Kafka from the official website: http://kafka.apache.org/downloads
You will need to choose the version you want to install, in our case we will choose version 2.8.0. Once you have clicked on the link, your download will start automatically.
$ wget https://dlcdn.apache.org/kafka/2.8.0/kafka_2.13-2.8.0.tgz
Once the download is completed, you will have a compressed file. Extract the file using the following command:
$ tar -xzf kafka_2.13-2.8.0.tgz
Next, go to the Kafka directory and start the services. Kafka uses ZooKeeper to manage the brokers, so you will need to start ZooKeeper first:
$ cd kafka_2.13-2.8.0
$ bin/zookeeper-server-start.sh config/zookeeper.properties
Once ZooKeeper is up and running, open a new terminal window and start the Kafka broker:
$ bin/kafka-server-start.sh config/server.properties
To verify that Kafka is running, you can create a test topic and publish a message to it. In a new terminal window, create a topic:
$ bin/kafka-topics.sh --create --topic my-topic --bootstrap-server localhost:9092
Next, publish a message to the topic:
$ bin/kafka-console-producer.sh --topic my-topic --bootstrap-server localhost:9092
Enter a message and hit Enter.
In another terminal window, subscribe to the topic and receive the message:
$ bin/kafka-console-consumer.sh --topic my-topic --from-beginning --bootstrap-server localhost:9092
You should see the message that you published.
Congratulations! You have successfully installed Kafka on OpenSUSE and verified that it is running. You can now use Kafka to publish and subscribe to messages in real time.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
