CentOS 7 + Nginx + PHP + MYSQL + Project example, environment construction and nginx.conf Update, test page http://wkb.kquanr.com/test.php can be opened correctly, but/HTTP Wkb.kquanr.com Main Page open always show blank
In nginx.conf has already configured the server, has added Fastcgi_param script_filename $document _root$fastcgi_script_name;
Database connection is correct, and import the relevant database SQL file correctly, the project redirection page still can't open, always show blank, hope to understand this piece of friend can help pointing, thank you
The following is the nginx.conf configuration file

User Nginx;
Worker_processes Auto;
Error_log/var/log/nginx/error.log;
Pid/run/nginx.pid;
Events {

worker_connections 1024;
