Request you to do the needfull. thanks in advance.

I have moved your thread to the Nagios Core forum as this is a Nagios Core question and does not relate to development.

Have you read our Nagios Core 4 documentation? Specifically, check out the quickstart section.

Also i have installed NRPE addon to motitor linux system but its not yet configured.
request you to guide me to how configure the same.

We also have NRPE documentation available. Most of our products have documentation available at http://library.nagios.com or via a quick Google search.

Please suggest on below error or warning:

[root@windows-i7qqp6m objects]# service nagios restart

There were no errors listed, only a single warning which is specified in the output:

Warning: Host 's1' has no default contacts or contactgroups defined!

It simply means that your s1 host does not have a contact(group) assigned to it. This will not cause Nagios to stop working, but it is informational and you may want to address it.
