the `www` in changing permissions command

December 26, 2013 1.5k views
I'm following this tutorial to setup wordpress with nginx https://www.digitalocean.com/community/articles/how-to-install-wordpress-with-nginx-on-ubuntu-12-04. At one point it asks us to create and cd into a directory /var/www/ cd /var/www/ It subsequently tells us to change the permissions for that directory with this command sudo chown www-data:www-data * -R sudo usermod -a -G www-data username My question is this, is there a relationship between the `www` of the /var/www/ and the `www` of the `www-data:www-data`. For example, if I didn't create the directory /var/www/ but instead created /var/foo/ directory, would the command for changing permissions look like this sudo chown foo-data:foo-data * -R or will the command always be sudo chown www-data:www-data * -R regardless of what I name the directory?

"My question is this, is there a relationship between the `www` of the /var/www/ and the `www` of the `www-data:www-data`."

None; www-data is the system name for the web server (whether Nginx or Apache). A popular root directory for a web server -- other than /var/www -- is /srv/www.
