Install and configure a Splunk platform indexer
This topic discusses installing the basic building block of a Splunk App for Windows Infrastructure deployment: a Splunk platform indexer.
In this procedure, you will install the indexer and then configure it to receive data from other Splunk platform instances.
If you're using TA-Windows version 6.0.0 or later, you don't need TA_AD and TA_DNS. TA_AD and TA_DNS are merged with TA-Windows version 6.0.0.
Install the indexer
To install an indexer:
- Prepare a host that meets or exceeds the Splunk platform system requirements. During preparations:
- Write down the host name and IP address for the host.
- Ensure that no firewall blocks any network traffic into the host.
- The software should start without error. If it doesn't, try troubleshooting it.
- You should be able to perform a basic search using the Search app. Learn how. If that doesn't work, figure out why.
If everything checks out, configure the indexer to have the correct indexes for the Splunk App for Windows Infrastructure.
The indexer must have the indexes for the Splunk App for Windows Infrastructure defined before you can begin indexing the data. Every indexer in a Splunk App for Windows Infrastructure environment needs this configuration file.
To get this file:
- In a web browser, proceed to the Splunk App for Windows Infrastructure download page.
- Click the download link to begin the download process.
- Make sure you download the latest version of the app.
- You might need to sign in with your Splunk account before the download starts.

> cd \Program Files\Splunk\bin > .\splunk restart
You can now configure the indexer to receive data from other Splunk instances.
The Splunk App for Windows Infrastructure depends on an indexer that can receive data from other hosts. Without this capability, the app cannot function. You will now enable receiving on this indexer.
To configure the indexer to receive data from other Splunk platform instances:
- Log into Splunk Enterprise on the indexer.
- In the system bar, click Settings > Forwarding and Receiving. Your Splunk platform loads the "Forwarding and Receiving" page.
- Under "Receive Data" click Configure Receiving.
- Click New.
- In the Listen on this port field, enter the port number that you want your Splunk platform to listen on for incoming data from other Splunk instances. The conventional port number is 9997.
- Click Save. Splunk Enterprise saves the port number and enables receiving on the indexer.
Your indexer is now configured to receive data. Confirm the host name or IP address and port number of the indexer. You will need it for the next step of the setup process.
Before you proceed, read our documentation on apps. You will create a simple app in the next step.
