"Lnmp" prompt nginx PHP "No input file specified" error solution

Principle:

Any request for a. php file is simply given to php-cgi, but the PHP file is not verified to exist.

PHP file does not exist, there is no way to return a normal 404 error, it returns a 404, and with a sentence "No input file specified"

In addition, it may be related to a path or permission, or the script_filename variable is not set correctly (this is the most common reason for nginx).

Workaround:

1 Open File: Usr/local/php/etc/php.ini, modify the following configuration

• Change Cgi.fix_pathinfo=0 to Cgi.fix_pathinfo=1
• change the cgi.force_redirect=1 to cgi.force_redirect=0 .

2 Modifying file permissions

# cd/home/wwwroot# Chown-r www:www/*# chmod-r 755/*# lnmp Restart

When it's time to execute. If there are. user.ini files in individual projects. Will prompt

chown:changing ownership of './www.test.com/.user.ini ': Operation not permitted

This is the time to enter this directory to execute

Then go to the Wwwroot directory, then execute the permissions command, and finally do not forget to enter the Www.test.com directory, execute

Last reboot

LNMP restart
