Take a deep breath. Please post a new question describing your problem. Forwarders are not installed on either search heads or indexers, but we'll address that with your question.

I would actually suggest focusing on what the official documentation has to offer. That way if you open a support case for help, you are in line with what is supported.

Two sets of documentation that will be of use to you: Distributed Deployment Manual and Distributed Search. The second link even has a page that walks you through exactly what you're working on.

Here are some notes I had which will summarize the steps. Even though you will have just one indexer, this will be the same process.

  • Install Indexers
  • Change default password on each Indexer (required for Search Head to connect)
  • Install Search Head
  • Install Licenses on Search Head (License Master)
  • Configure each Indexer as a License Slave
    • Settings > Licensing
    • Click Change to slave
    • Click Designate a different Splunk instance as the master license server radio button
    • Specify the IP/Hostname and Splunk management port (8089 by default)
    • Save
  • Establish connections from Search Head to all Search Peers. This is the key step.
    • Distributed search > Search peers > Add New
    • Specify the search peer, along with any authentication settings
    • Save
  • Install Universal Forwarders and configure to send to all Search Peers

    • Example Universal Forwarder outputs.conf
      [tcpout]
      defaultGroup = mysearchpeers

              [tcpout:my_search_peers]
              server=10.10.10.1:9997,10.10.10.2:9997                                                
              autoLB = true
      
  • Forward internal SH data to the indexer tier.

    • Create indexes from SH on the indexers (search peers). Internal indexes will already exist, but indexes created by apps can be easily created by installing the apps on the indexers as well.
    • Set SH up to Forward to all Search Peers.
    • Example outputs.conf
    • Turn off indexing on the search head

      [indexAndForward]
      index = false

      [tcpout]
      defaultGroup = mysearchpeers
      forwardedindex.filter.disable = true
      indexAndForward = false

      [tcpout:mysearchpeers]
      server=10.10.10.1:9997,10.10.10.2:9997

    •       autoLB = true
      

Configuration via files:

Change password from changeme to something else on the indexers:

./splunk edit user admin -password foo -role admin-auth admin:changeme

Configure indexers as license slaves: https://docs.splunk.com/Documentation/Splunk/6.6.2/Admin/LicenserCLIcommands
./splunk edit licenser-localslave -master_uri 'https://master:8089'

Add search peer to Search Head:
splunk add search-server https://192.168.1.1:8089 -auth admin:password -remoteUsername admin -remotePassword passremote

also you said in last part that forwarder not need to install on search head , but in your commands you turn off this form search peer(indexer) . it confused me.
[tcpout]
defaultGroup = mysearchpeers
forwardedindex.filter.disable = true
indexAndForward = false
[tcpout:mysearchpeers]
server=10.10.10.1:9997,10.10.10.2:9997

* autoLB = true
