CentOS 7+Nginx+PHP+MySql+Project Example, Environment Building and nginx.conf Update, Test Pagehttp://wkb.kquanr.com/test.phpCan be opened correctly, buthttp://wkb.kquanr.comThe main page is always blank when opened.
The server has been configured in nginx.conf and FastCGI _ ParamScript _ FileName $ Document _ Root $ FastCGI _ Script _ Name has been added.
The database connection is correct, and the relevant database sql files are imported correctly. The project redirection page still cannot be opened and has been blank. I hope the friends who understand this section can help me point out, thank you
