That is served from main hostname you setup at Getting Started Guide step 1 outlined at Getting Started Guide - CentminMod.com LEMP Nginx web stack for CentOS which uses nginx vhost at /usr/local/nginx/conf/conf.d/virtual.conf file and has it's web root at /usr/local/nginx/html You can see listed in Centmin Mod Config Files page too.
