Welcome to nginx on Fedora!

        

            
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
                    Fedora.  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.
