Apache Nifi on Ubuntu

Apache Nifi is created to simplify data transfer between computer programs. The software’s design is based on the flow-based programming model. It has the following features:

• Capacity to work in clusters
• Security provided by TLS encryption
• Extensibility & Enhanced usability features

Today, we will see how we can see the steps to use Apache Nifi on an Ubuntu system.

Set up Apache Nifi on Ubuntu

1. Java is required for Nifi to function. So, firstly, we have to set up the Java JDK package. We can use the following command to set up the Java JDK package.

   apt-get update
   apt-get install openjdk-8-jdk

    
2. Now find the Java JDK setup directory with the below command.

   update-alternatives --config java

    
3. Then we have to create an environment variable named JAVA_HOME. So let’s make a file to automate the setting up of the necessary environment variables.

   vi /etc/profile.d/java.sh

    

   The java.sh file content is as follows:

   #/bin/bash
   export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64

    
4. Reboot the system now.

   reboot

    
5. Now use the following command to verify if the JAVA_HOME variable was created.

   env | grep JAVA_HOME
   JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64

    
6. Test the Java setup, use the below command:

   java -version

    
7. Now we have to download Apache Nifi. So download the Nifi tar file. Else, use the wget command from the terminal to download the file.

   mkdir /downloads/apache-nifi -p
   cd /downloads/apache-nifi
   wget https://downloads.apache.org/nifi/1.13.2/nifi-1.13.2-bin.tar.gz

    
8. Now set up Apache Nifi on Ubuntu.

   tar -zxvf nifi-1.13.2-bin.tar.gz
   mv nifi-1.13.2 /opt/
   ln -s /opt/nifi-1.13.2/ /opt/nifi
   cd /opt/nifi
   bin/nifi.sh install

    
9. Start the Nifi service.

   /etc/init.d/nifi start

    

   The result will be as follows:

   Java home: /usr/lib/jvm/java-8-openjdk-amd64
   NiFi home: /opt/nifi-1.13.2Bootstrap Config File: /opt/nifi-1.13.2/conf/bootstrap.conf

    
10. Open a browser and put the Apache Nifi server’s IP address, plus :8080/nifi. For E.g., http://192.168.15.10:8080/nifi/
11. The web interface for Apache Nifi is finally displayed.
