1. include /etc/nginx/conf.d/*.conf;
2. include /etc/nginx/sites-enabled/*;

The first reference is the CONF.D path under the configuration file, the disableip.conf file into the Conf.d folder to make this server at the forefront, the rule is first applied, the modification is completed after the restart Nginx ( service nginx restart ), the following test:

1. Enter the IP address directly
   
2. Enter the domain name
