Getting Started with Apache NiFi

Installing as a Service

Currently, installing NiFi as a service is supported only for Linux and Mac OS X users. To install the application as a service, navigate to the installation directory in a Terminal window and execute the command bin/ install to install the service with the default name nifi. To specify a custom name for the service, execute the command with an optional second argument that is the name of the service. For example, to install NiFi as a service with the name dataflow, use the command bin/ install dataflow.

Once installed, the service can be started and stopped using the appropriate commands, such as sudo service nifi start and sudo service nifi stop. Additionally, the running status can be checked via sudo service nifi status.
