Apache Server Permission Error

Every single time I create a new apache server I forget to give permissions to the www-data group. So I'm pasting a great answer I got from stackoverflow to this blog for future reference.

//Create new group
$ sudo addgroup webdev

//Change the group of your web directory:
$ sudo chgrp -R webdev /var/www/
$ sudo chmod -R g+rw /var/www/

//Set the guid bit on all folders in your web directory:
$ sudo find /var/www -type d -exec chmod +s {} \;

//Add Apache to the webdev group:
$ sudo usermod -a -G webdev www-data

//Add your user to the webdev group:
$ sudo usermod -a -G webdev <user_name>

Hopefully this helps someone
