Dependencies

1. Maven 3.3+
2. Java 1.8
3. Apache NiFi

Build

1. Download and build Apache NiFi using maven. This project needs nifi-bootrap to compile and run, or at least that jar file.
2. The file pom.xml contains a property for the NiFi version. Adjust as necessary before building.
3. Download the source and run: mvn install. An output directory will be created at $root/Dist.

Installation

1. Copy the nifi-windowsservice.VERSION.jar file into NiFi's /lib/bootstrap directory.
2. Copy everything in /dist/bin to NiFi's /bin folder.
3. Execute /bin/install_service.bat.
4. The service will show up in the service controll manager as "Apache NiFi", with a service name of "nifi-service".
5. If you need to run service as user other than system account, you may need to set JAVA_HOME environment variable that new user can see (e.g. as a system variable).
6. You may need to grant permissions (full access) to service run-as user to entire nifi installation folder.

Uninstallation

Uninstallation can be done in two ways:

1. Execute the Windows service manager commands sc delete nifi-service.
2. Run the command /bin/nifi-service.exe //DS//nifi-service

Notes

• When NiFi starts up, it unpacks all jars. This may take some time. If you issue the stop command during this time, it may take a while for the service to stop. The apache daemon may even terminiate the process if it is taking too long, but rest assured, the shutdown has been properly initiated.
