Using umask to set permission when clearing cache

Question

I can't use ACL, so I've tried to add umask(0000) to the app/console and web/app.php in my VPS, but the permissions of app/cache are turned again to 0755 and owner group to myFTPUser when I clear cache, so my site throws an error until I change permissions again to 0775 and group owner to www-data:

php app/console cache:clear --env=prod --no-debug
chown -R myFTPUser:www-data app/cache/
find app/cache/ -type d | xargs chmod -R 0775
find app/cache/* -type f | xargs chmod -R 0664

The only way I've found out is to change user to Apache user before clear cache, without changing umask:

su www-data
php app/console cache:clear --env=prod --no-debug

And now it works right without doing anything else. But, is it the right way to go? and, why Symfony2 documentation doesn't clarify this point?

Answer 1

You will have to run this command from the apache user.

If this is a development environment then it's not a bad thing to set the user to your own user. However in a production environment you would more than likely just have to switch to the apache user.
