Apache Kafka, a powerful distributed event streaming platform, has become an essential tool for handling real-time data feeds. Its versatility and robustness make it a favorite among developers, particularly for applications requiring high throughput and scalable data processing. This guide simplifies the Kafka installation process on an Ubuntu 22.04 system, ensuring you can get your Kafka server up and running with minimal fuss. Given the global nature of Kafka’s applications, it’s worth noting how Kafka’s performance might vary based on the server’s location, such as a ukraine server, affecting latency and throughput depending on the geographical distribution of end-users.
Before diving into the installation process, ensure your system meets the following prerequisites:
- An Ubuntu 22.04 server setup
- A non-root user with sudo privileges
- Java 8 or 11 installed on your system (Kafka is written in Java)
Step 1: Install Java
Kafka requires Java to run. If you haven’t installed Java yet, follow these steps:
- Update your system’s package index:
sudo apt update
- Install the default Java (OpenJDK) package:
sudo apt install default-jdk
- Verify the installation by checking the Java version:
java -version
Step 2: Download and Extract Kafka
- Navigate to the Kafka downloads page at https://kafka.apache.org/downloads to find the latest version of Kafka or use the following command to download Kafka directly:
wget https://downloads.apache.org/kafka/2.8.0/kafka_2.13-2.8.0.tgz
- Extract the downloaded archive:
tar -xzf kafka_2.13-2.8.0.tgz
- Move the extracted folder to a more convenient location:
sudo mv kafka_2.13-2.8.0 /usr/local/kafka
Step 3: Configure Kafka
Before starting Kafka, it’s necessary to configure it properly:
- Navigate to the Kafka configuration directory:
cd /usr/local/kafka/config
- Edit the server properties file:
nano server.properties
- You can leave the configuration as is for a basic setup. However, make sure the listeners and advertised.listeners properties are uncommented and set correctly if your Kafka server needs to be accessible over a network.
Step 4: Start the Kafka Server
- Navigate back to the Kafka home directory:
cd /usr/local/kafka
- Start the Kafka server:
bin/kafka-server-start.sh config/server.properties
To ensure the Kafka server starts automatically at boot, you can set up a systemd service or use other similar methods.
Optimizing Kafka Performance
To get the most out of your Kafka installation, especially in data-intensive environments, it’s crucial to consider the hardware and infrastructure it runs on. For instance, deploying Kafka on an nvme dedicated server can significantly enhance performance due to the superior data transfer speeds and lower latency of NVMe drives compared to traditional SSDs. This is particularly beneficial for applications that demand high throughput and minimal delay in data processing.

Additional Tips
- Monitoring and Management: Consider using tools like Kafka Manager or Confluent Control Center for easier management and monitoring of your Kafka cluster.
- Security: Secure your Kafka cluster by implementing SSL/TLS encryption and using SASL for client authentication.
- Backup: Regularly back up your Kafka data and configuration to avoid data loss.
By following this straightforward guide, you should now have Apache Kafka running on your Ubuntu 22.04 server. Whether you’re setting up a development environment or deploying a production-ready Kafka cluster, understanding the basics of Kafka installation and configuration is crucial. Remember, the choice of hardware and server location, such as deploying on a “nvme dedicated server,” can profoundly impact Kafka’s performance, enabling you to achieve the high-throughput, scalable data processing Kafka is known for.
