The created Splunk installation and setup follows best practices using base config apps from Splunk. 3 Step 3.Ever wanted to build a complex Splunk environment for testing, which looks as close as possible to a production deployment? Need to test a Splunk upgrade? See how Splunk indexer- or search head clustering works? Or just need to verify some configuration changes? This is the right place for you! The aim of this framework is to produce a Splunk environment in a fast and convenient way for testing purposes or maybe also for production use. 2 Step 2: Open the Shell to type commands. Installation packages contain logic that checks for software dependencies and install in a predetermined place, depending on your operating system.Setup Splunk Universal Forwarder Now 1 Step 1: Download and Install Splunk Universal Forwarder Linux.
