I am creating a website and part of the function is to write out user generated data with php. I'm using nginx on Ubuntu 13.04. A the moment I'm only testing and everything is served through nginx on locahost.
My php script fails to write the text file (although I can do this manually) and I think it's a permissions problem for writing to my /var/www/example.com/public_html directory.
At the moment I (iain) own this directory but it seems it would make more sense to transfer ownership of the /var/www directory and everything inside that to the www-data user (or should that be group?) and add myself to the www-data group. Is the following the right way to do this?
useradd -G www-data iain chown -R www-data:www-data /var/www/example.com chmod 775 /var/www
So does this mean anyone in the www-data group can now read, write and exec in /var/www?
