PHP-FPM What permisions phpfpm is using?

AFAIK, it shouldn't php created files should be nginx permission based if the php script executing has nginx permissions. But if you as root user ran php script, then that would have root permissions. In which case you just chown them.

How is the php script executed/ran/called ? Does the script itself use nginx:nginx user/group permissions ?

 

You need to specify to run cron script as nginx and not the default if not specified = root
