Start Splunk for the first time

Start the server

Splunk's command line interface is located in $SPLUNK_HOME/bin/. Navigate to this location and run the following command:

# ./splunk start

Use whatever path you installed under.

The first time you start splunk after a new installation, you will be presented with the license agreement and asked to accept the license. If you want to bypass these steps, you can start splunk and accept the license in one step:

# ./splunk start --accept-license

Please note: there are two dashes before the accept-license option.

Load SplunkWeb in your browser

Navigate to:

http://mysplunkhost:8000

Use whatever host and port you chose during installation.

The first time you login to Splunk with an Enterprise license, use username admin and password changeme. Splunk with a free license does not have access controls.
