Kafka is a distributed messaging system that is widely used for its high throughput, low latency, fault tolerance, and scalability. In this tutorial, we will show you how to install Kafka on Fedora CoreOS Latest.
Before we proceed with the installation of Kafka, we first need to ensure that the following prerequisites are met:
To download Kafka, you can visit the official website at http://kafka.apache.org/downloads. Under the "Quick Start" section, click the download link for the latest stable release.
Alternatively, you can use the following command to download Kafka from the command line:
wget https://downloads.apache.org/kafka/2.8.0/kafka_2.12-2.8.0.tgz
Once Kafka has been downloaded, navigate to the directory where the file was downloaded and extract it using the following command:
tar -xzf kafka_2.12-2.8.0.tgz
This will extract Kafka into a directory named kafka_2.12-2.8.0.
In order to configure Kafka, we need to modify the configuration file located in the config directory of the Kafka installation. Open the server.properties file using the following command:
vi kafka_2.12-2.8.0/config/server.properties
Make the following changes to the configuration file:
advertised.listeners=PLAINTEXT://<hostname>:9092
num.partitions=3
log.retention.hours=168
zookeeper.connect=<hostname>:2181
Replace <hostname> with the hostname of your machine.
To start the Kafka server, navigate to the Kafka installation directory and run the following command:
bin/kafka-server-start.sh config/server.properties
Kafka will start and begin listening on the specified port.
To verify that Kafka has been successfully installed, you can create a topic and publish a message to it using the following commands:
bin/kafka-topics.sh --create --zookeeper <hostname>:2181 --replication-factor 1 --partitions 3 --topic test
bin/kafka-console-producer.sh --broker-list <hostname>:9092 --topic test
Enter your message and hit Ctrl+D to publish it.
You can then consume the message using the following command:
bin/kafka-console-consumer.sh --bootstrap-server <hostname>:9092 --topic test --from-beginning
If you see the message that you published, this indicates that Kafka has been successfully installed on your system.
By following the steps outlined in this tutorial, you should now have Kafka installed and running on your Fedora CoreOS Latest system. Kafka is a powerful messaging system that can be used for a wide range of applications, and we hope that this tutorial has helped you to get started with using Kafka on your own system.
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!
