How to install and start NiFi

• Linux/Unix/macOS

  • Decompress and untar into desired installation directory

  • Make any desired edits in files found under <installdir>/conf

    • At a minimum, we recommend editing the nifi.properties file and entering a password for the nifi.sensitive.props.key (see System Properties)

  • From the <installdir>/bin directory, execute the following commands by typing ./nifi.sh <command>:

    • start: starts NiFi in the background

    • stop: stops NiFi that is running in the background

    • status: provides the current status of NiFi

    • run: runs NiFi in the foreground and waits for a Ctrl-C to initiate shutdown of NiFi

    • install: installs NiFi as a service that can then be controlled via

      • service nifi start

      • service nifi stop

      • service nifi status

• Windows

  • Decompress into the desired installation directory

  • Make any desired edits in the files found under <installdir>/conf

    • At a minimum, we recommend editing the nifi.properties file and entering a password for the nifi.sensitive.props.key (see System Properties)

  • Navigate to the <installdir>/bin directory

  • Double-click run-nifi.bat. This runs NiFi in the foreground and waits for a Ctrl-C to initiate shutdown of NiFi

  • To see the current status of NiFi, double-click status-nifi.bat

When NiFi first starts up, the following files and directories are created:

• content_repository

• database_repository

• flowfile_repository

• provenance_repository

• work directory

• logs directory

• Within the conf directory, the flow.xml.gz file is created

See the System Properties section of this guide for more information about configuring NiFi repositories and configuration files.
