Resolution: 500 error occurred accessing PHP page LNMP schema

By default, if the PHP script being accessed contains syntax errors, the server returns an empty "OK" page

The Fastcgi.error_header option in PHP.ini allows an HTTP error code to be generated in this case

So that the Web server can properly intercept and process this error code, similar to calling header () directly in PHP code to return a 500 status code, such as

Header ("http/1.1 Internal Server Error");

Reconfigure: Set display_errors = on Turn On error display in php.ini, all right

In addition, the php.ini option set in php-fpm.conf takes precedence over the options set in php.ini, such as

Set display_errors = on in php.ini

Set Php_flag[display_errors] = off in php-fpm.conf

So the result is off.
