It is intended to complement the link:overview.html[NiFi Overview^], link:administration-guide.html[NiFi System Administrator's Guide^], and link:user-guide.html[NiFi User's Guide^]. Those documents provide extensive reference information about various features and configuration values, but they do not provide information on _how_ to accomplish tasks. + +This document is _not_ intended to be a comprehensive repository of all possible admin or user activities, but rather a collection of well-documented reference activities which can be followed directly or adapted to custom scenarios. This document requires continued updates as application or ecosystem behavior changes, and corrections and improvements where the content is unclear to the community. To contribute to this document, please link:https://issues.apache.org/jira/secure/CreateIssue!default.jspa[open a Jira^] (see link:https://cwiki.apache.org/confluence/display/NIFI/Contributor+Guide#ContributorGuide-WheretoStart?[further instructions in the Contributor Guide^]) and link:https://github.com/apache/nifi/pulls[submit a pull request (PR)^]. + +NOTE: This document is provided with no warranty. All steps have been evaluated for correctness to the extent possible by the Apache NiFi community, but no responsibility is assumed for negative impacts on any computer system where these commands are executed. + +== Installing Apache NiFi + +Apache NiFi is an easy to use, powerful, and reliable system to process and distribute data. It supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. In addition to NiFi, there is the NiFi Toolkit, a collection of command-line tools which help perform administrative tasks such as interacting with remote services, generating TLS certificates, managing nodes in a cluster, and encrypting sensitive configuration values. + +|======================================================================================================================= +|Description | Instructions on downloading the Apache NiFi application and Toolkit +|Purpose | To make the application available to run on the specified machine (e.g. a local development environment) +|Starting Point | Machine running modern OS +|Expected Outcome | Latest version of Apache NiFi available to run on host with no configuration +|Estimated Duration | 1 minute + download time +|======================================================================================================================= + +NOTE: The following instructions are for installing a single node of NiFi.

The TLS Toolkit provides an option to consume an existing `nifi.properties` file and make the security changes to it rather than using a default template. Use `-f /etc/nifi-1.11.4/conf/nifi.properties` or `--nifiPropertiesFile /etc/nifi-1.11.4/conf/nifi.properties` if this file already exists.
