Getting Started with Confluent Platform on Ubuntu

In this post, we’ll walk through setting up a single-node Confluent Platform cluster on your local Ubuntu machine. This configuration is perfect for development and learning purposes, allowing you to explore Kafka and its ecosystem without the need for a full-scale production setup.

Prerequisites

Before you begin, ensure your Ubuntu machine has the following installed:

• JDK 17: A Java Development Kit is required to run Confluent Platform components.

Installation Steps

Follow these steps to download, extract, and configure the Confluent Platform:

1. Download the Confluent Platform Tarball

• Open your terminal.
• Navigate to the directory where you want to install the Confluent Platform. For example, if you want to use /home/user/kafkawizamr/, run:
• Run the following curl command to download the tarball containing the Confluent Platform:

curl -O https://packages.confluent.io/archive/7.8/confluent-7.8.0.tar.gz        

2. Extract the Tar File

After the download completes, extract the tarball using:

tar xzf confluent-7.8.0.tar.gz        

Once extracted, you should see a folder named confluent-7.8.0 containing the following structure:

• /bin/: Driver scripts for starting and stopping services.
• /etc/: Configuration files.
• /lib/: Systemd services.
• /libexec/: Multi-platform CLI binaries.
• /share/: Jars and licenses.
• /src/: Source files that require a platform-dependent build.

3. Configure Environment Variables

Set up your environment so that your system can easily run Confluent Platform commands:

• Open your .bashrc file in your favorite text editor:
• Scroll to the end of the file and enter insert mode.
• Add the following lines to define CONFLUENT_HOME and update your PATH:

export CONFLUENT_HOME=/home/user/kafkawizamr/confluent-7.8.0
export PATH=$PATH:$CONFLUENT_HOME/bin        

• Save the file and exit.

4. Start Confluent Platform Services

With your environment configured, start all the Confluent Platform components using:

confluent local services start        

5. Verify the Installation

Open your web browser and navigate to https://localhost:9021. You should see the Confluent Control Center running, indicating that your local Confluent Platform cluster is up and running.
