Need help administrirovanie server

Bought additional ip, prescribed it in settings and the site began to show a page with the following inscription:

Welcome to nginx on EPEL!

This
page is used to test the proper operation of the nginx HTTP server
after it has been installed. If you can read this page, it means that
the web server installed at this site is working properly.
Website Administrator

This is the default index.html page that is distributed with nginx on EPEL. It is located in /usr/share/nginx/html.

You
should now put your content in a location of your choice and edit the
root configuration directive in the nginx configuration file
/etc/nginx/nginx.conf.


HOW TO REMOVE IT?
