Permission denied whenever uploading files

I am running the LEMP Stack on Ubuntu 14.04

I am always getting permission denied whenever my php file is trying to save or upload something. If I chmod the folder to 777 it works but I don't want to change it to 777. I checked the owner of all the files in my application . It is root / root (owner / group ).

I have the exact same project on a different server with permissions set as 0755 and the owner as 501 / 500 and the application works flawlessly. But I don't know that the 501 / 500 stands for.

Also I just checked the following for my application:

/usr/share/nginx/html/example1/app/webroot
script owner : root
script getmyuid : 0
script getmygid : 0

How come the script owner is root and I still get permission denied ?

By default the nginx process runs as the user www-data. Changing the ownership of your files and directories inside your web root to this user will allow nginx to create new files and directories in this path.

chown -Rf www-data.www-data /usr/share/nginx/html/*

    worked, thanks ! How can I know under which user a process runs ?

    One way is to run "top" when the process is running. It will indicate the user the process is being run by. On Ubuntu Apache and nginx always use the user www-data. On CentOS/Fedora the user is generally "httpd" by default.

If you are running apache on Ubuntu 14.04 you want to invoke it as such

sudo chown -Rf www-data:www-data </var/www/html/*
