CentOS Configuration LNMP Environment Open prompt file not found

After the installation test found that how HTML can run, and PHP is not, show file not Found, is very sad Google, found a variety of strange sayings, as a error_log can not understand the people could only try, and I will install the steps carefully repeated over and over again, Make sure to follow the tutorial, or not find the problem, and finally found a similar answer:

is a problem with the configuration

Location ~. php$ {
root HTML;

HTML is the Nginx default directory that needs to be changed to the actual path of the site

And then I'm pretty sure. Under/etc/nginx/conf.d/default.conf, after repeated revisions, I found a different point:
root/usr/share/nginx/html, but in PHP, it's root HTML.

So the access is not, the original path is wrong, after the modification can be accessed.

In addition, the error log is located at: Var/log/nginx
