Explain that the result is returned by FastCGI.

problem causes:

I guess it has something to do with permissions

The same configuration, using the following two: 

/opt/local/share/nginx/html  
/opt/local/share/nginx/html/php

Directories are fine, but use: 

/Users/xxx/Downloads/workForder

Directory does not.

Check the permissions through ls -l and find that the difference is 

/Users/xxx/Downloads/workForder

The files in the directory have no extended attributes, that is, no @ sign.

Later, modify Nginx's static file root directory to:

/Users/xxx/Downloads/workForder

Access appears:

403 forbidden error

Look at  nginx 403 again and find the cause of the problem. You need to modify the user and group in the configuration file.

The format of nginx is:

user your username/root owner;
for example:
user root owner;

Respective modification of PHP-fpm:

user = root
group = owner

Then reboot.

PHP-fpm itself has no restart command, which is quite pitiful! Just kill the process.

Configuration file:

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #

        location ~ \.php$ {
            root           /Users/xxx/Downloads/workForder;
           # root           /opt/local/share/nginx/html/php;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            include        fastcgi.conf;

         }

Only the part related to PHP is shown here. when i add in the config 

try_files $uri =404;

 After that, you will see what is returned by Nginx:

When accessing PHP files, you may see errors like the following:

That's because FastCGI is not started and needs to be started:

sudo php-fpm  -D

And if both Nginx and PHP point to the same directory, you will still see:

File not found
