Apache Kafka is a distributed streaming platform that is used for building real-time data pipelines and streaming applications. In this tutorial, we will explain how to install Kafka on NetBSD.
Download Kafka
First, navigate to the official Kafka downloads page at http://kafka.apache.org/downloads. Scroll down and look for the latest stable release version. Then, copy the link for the binary download file (for example, https://archive.apache.org/dist/kafka/2.6.1/kafka_2.13-2.6.1.tgz).
Next, open a terminal window and execute the following command to download the Kafka binary file:
$ wget https://archive.apache.org/dist/kafka/2.6.1/kafka_2.13-2.6.1.tgz
Extract the Kafka archive
Once the download completes, extract the downloaded archive using the following command:
$ tar -xzf kafka_2.13-2.6.1.tgz
This command will extract the Kafka archive to a directory named kafka_2.13-2.6.1.
Change the directory
Navigate to the Kafka directory using the following command:
$ cd kafka_2.13-2.6.1/
Start the Kafka server
Now, you need to run the Kafka server. You can run it in a terminal window by executing the following command:
$ bin/kafka-server-start.sh config/server.properties
This will start the Kafka broker, which should start up without any issues.
Create a Kafka topic
With the server running, you can now create a Kafka topic. Open another terminal window and navigate to the Kafka directory. Then, execute the following command:
$ bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic test
Verify
To verify that Kafka has been successfully installed and configured, you can run the following command:
$ bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning
This will start a Kafka console consumer that will read the messages from the test topic.
Finally, to stop the Kafka server, simply type Ctrl-C in the terminal window where the Kafka broker was started.
Congratulations! You have successfully installed Kafka on NetBSD.
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!
