Basic Installation of Apache NiFi: Start Your Journey in Data Engineering!

Hello Devs! If you’re taking your first steps into the exciting world of data engineering, Apache NiFi is an essential tool you can’t miss. This post will guide you through the basic installation process so you can start exploring its full potential. 🌟

1. Download Apache NiFi

First things first: head over to the Apache NiFi website and download the version that best fits your operating system:

  • Linux/Mac OS: Choose the .tar.gz package.
  • Windows: Download the .zip file.

Once downloaded, extract the package into a folder that we’ll call NIFI_HOME. This will be the core of your installation! ❤️

2. Basic Requirements

Before you begin, make sure you have the following ready:

  • A text editor (such as Notepad++, VS Code, or Atom).
  • A tool to extract compressed files, if your system doesn’t have one built-in (7-Zip or WinRAR are excellent options).
  • Java 8 or Higher: While NiFi is compatible with both versions, Java 11 is recommended to take advantage of its latest optimizations. You can download it from:

3. Initial Configuration

Apache NiFi comes ready to use with default settings, but making a few adjustments can optimize its performance:

  • Memory: Edit the file NIFI_HOME/conf/bootstrap.conf to allocate more RAM. For example:plaintextCopiar códigojava.arg.2=-Xms1024m java.arg.3=-Xmx2048m This will allocate a minimum of 1 GB and a maximum of 2 GB.
  • Port: By default, NiFi uses port 8080. To change it, edit the file NIFI_HOME/conf/nifi.properties:plaintextCopiar códigonifi.web.http.port=8080
  • Java Home: If you need NiFi to use a specific version of Java, edit the file NIFI_HOME/bin/nifi-env.bat (Windows) or nifi-env.sh (Linux/Mac OS) by adding the following line:plaintextCopiar códigoset JAVA_HOME=/path/to/your/java

4. It’s Time to Start NiFi!

With everything set up, start Apache NiFi based on your operating system:

  • Windows: Open the file run-nifi.bat from the folder NIFI_HOME/bin.
  • Linux/Mac OS: Navigate to NIFI_HOME/bin and run:bashCopiar código./nifi.sh run

When NiFi is up and running, open your browser and go to http://localhost:8080/nifi/. Done! Now you can explore NiFi’s graphical interface and begin designing your data flows.
