How To Install Apache Kafka on Ubuntu 18.04 LTS

Install Apache Kafka on Ubuntu 18.04 LTS

In this tutorial we will show you how to install Apache Kafka on Ubuntu 18.04 LTS. For those of you who didn’t know, Apache Kafka is a distributed message agent designed to deal with huge volumes of real time information effectively. Unlike traditional agents like ActiveMQ and RabbitMQ, Kafka functions as a bunch of one or more servers that makes it highly scalable and because of the distributed nature, it’s inbuilt fault-tolerance whilst providing greater throughput when compared to its counterparts.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Apache Kafka on a 18.04 LTS (Bionic Beaver) server.

Install Apache Kafka on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

Step 2. Installing Java.

Apache Kafka requires Java to be installed on your server. By default, Java is not available in Ubuntu’s repository. Add the Oracle Java PPA to Apt with the following command:

Verify the Java version by running the following command:

Step 3. Installing Zookeeper.

Apache Kafka depends on Zookeeper for cluster management. Hence, prior to starting Kafka, Zookeeper has to be started:

You can run the following command to check whether zookeeper is running:

Now you can see the created topic on Kafka by running the list topic command:

Step 6. Send Messages to Kafka.

The “producer” is the process responsible for put data into our Kafka. The Kafka comes with a command line client that will take input from a file or from standard input and send it out as messages to the Kafka cluster:

Let’s run the producer and then type a few messages into the console to send to the server:

Step 7. Using Kafka Consumer.

Kafka also has a command line consumer to read data from Kafka cluster and display messages to standard output:
