I have Ubuntu server that is running a nginx server that has configured a bunch of sites that run php.



PHP is running under php-fpm.



In my php-fpm config, the 'user' and 'group' match the linux user to which the index.php file belongs.



So it works fine as long as all site directories have 755 permissions.



But once I chmod the directories so only the owners can have access to them (700), the sites stop working and I get a forbidden server message.



I don't understand why, because php-fpm is supposed to run under the same user that is the owner of the site directory.



Is it because the listen.owner and listen.group is www-data ?

  • If there was an earlier comment, it seems to have been deleted. The web server should be able to read the file to serve it over HTTP. Otherwise, how would 'index.php' be accessible over an HTTP URL?
