Individual component configurations 

The configuration steps and settings to be completed next depend on the Splunk function that a particular server will perform – let's go through these settings to complete the initial Splunk deployment, component by component. Most configuration settings can be accomplished from the Splunk Web GUI or via the CLI, but some can only be accomplished by editing a specific .conf file. We will do as much as is practical from the GUI.

You may want to add these steps to your checklist, if you choose to make one, so that you have a complete record of how your Splunk deployment was configured for future reference. I like to copy/paste the contents of especially the server.conf, inputs.conf, and outputs.conf files off to the side of my configuration checklist spreadsheet, and any other files altered during the process.
