Install the new NiFi into a directory parallel to the existing NiFi installation.
-
Download the latest version of Apache NiFi from the Download
location documentation.
- 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/.
- Create or update a symlink: /opt/nifi/current →
/opt/nifi/<nifi build dir>
- If you are upgrading a NiFi cluster, repeat these steps on each node in the cluster.
