Installing Kafka

To start using Kafka, you need to install it on your local machine. Follow the step-by-step guide below to install Kafka:

1. Download Kafka:

   • Navigate to the Apache Kafka downloads page.
   • Download the latest stable version of Kafka by clicking the download link for your preferred operating system.
   • Save the downloaded file to a location on your computer.

2. Extract Kafka:

   • Open a terminal or command prompt.
   • Navigate to the directory where you saved the downloaded Kafka file.
   • Extract the Kafka archive file using the appropriate command for your operating system.
     • For example, if you downloaded the .tgz file on Linux/macOS, use the following command:
       SNIPPET

       1tar -xzf kafka_<version>.tgz

     • If you downloaded the .zip file on Windows, right-click the file and select "Extract All..." to extract the contents.

3. Start ZooKeeper:

   • Kafka requires ZooKeeper for coordination.
   • Open a new terminal or command prompt.
   • Navigate to the Kafka installation directory.
   • Run the following command to start ZooKeeper:
     SNIPPET

     1bin/zookeeper-server-start.sh config/zookeeper.properties

4. Start Kafka:

   • Open another terminal or command prompt.
   • Navigate to the Kafka installation directory.
   • Run the following command to start Kafka:
     SNIPPET

     1bin/kafka-server-start.sh config/server.properties

Congratulations! You have successfully installed Kafka on your local machine. You can now start using Kafka for building real-time streaming applications.
