In this tutorial, we will guide you through the process of installing Apache Kafka on Linux Mint. Kafka is a fast, scalable, distributed, and fault-tolerant messaging system that is widely used by companies of all sizes to handle real-time data streams.
Before we get started, make sure you have the following prerequisites:
java -version
To begin the installation process, you need to download Kafka. You can download the latest stable release from the Kafka website by running the following command:
wget https://downloads.apache.org/kafka/2.8.1/kafka_2.13-2.8.1.tgz
This will download the Kafka package to your system.
Once the download is complete, you can extract the package to the desired location using the tar command:
tar -xzf kafka_2.13-2.8.1.tgz
This will create a directory named kafka_2.13-2.8.1 in your current directory.
Before we start Kafka, we need to change some configuration settings. Navigate to the Kafka directory:
cd kafka_2.13-2.8.1/
Next, open the server.properties file using your favorite text editor:
nano config/server.properties
Find the following line:
#listeners=PLAINTEXT://:9092
Uncomment it and replace it with:
listeners=PLAINTEXT://localhost:9092
Save and close the file.
Now that Kafka is configured, we can start it by running the following command:
bin/kafka-server-start.sh config/server.properties
This will start the Kafka server.
Now that Kafka is running, we can create a topic to test it out. Open a new terminal window and navigate to the Kafka directory. Then, run the following command to create a topic:
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
This will create a topic named "test" with one partition and one replica.
With the "test" topic created, we can now publish messages to it. Open a new terminal window and navigate to the Kafka directory. Then, run the following command to start a producer:
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test
This will start a console where you can enter messages that will be published to the "test" topic.
To consume messages, open a new terminal window and navigate to the Kafka directory. Then, run the following command to start a consumer:
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning
This will start a console where you can see the messages that are being consumed from the "test" topic.
Congratulations! You have successfully installed Kafka on Linux Mint and created a topic that you can use to publish and consume messages. Kafka is a powerful messaging system that can be used for a wide range of data streaming use cases.
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!
