Install the new NiFi version

Install the new NiFi into a directory parallel to the existing NiFi installation.

  1. Download the latest version of Apache NiFi from the Download location documentation.
  2. Uncompress the NiFi .tar file into a directory parallel to your existing NiFi directory: 
    tar -xvzf file-name

    For example, if your existing NiFi installation is installed in /opt/nifi/nifi-1.2.0.3.0.2.0-76/, install your new NiFi version in a path similar to /opt/nifi/nifi-1.11.4.2.0.1.0-71/.

  3. Create or update a symlink: /opt/nifi/current → /opt/nifi/<nifi build dir>
  4. If you are upgrading a NiFi cluster, repeat these steps on each node in the cluster.
