A better and more secure solution (i get uneasy with the internet having access to an admins home folder!) is to create a webroot folder in /
sudo mkdir /webroot
sudo groupadd webdev
sudo usermod -a -G webdev yourusername
sudo chown www-data:webdev /webroot/
Now point apache to your new document root /webroot at the bottom of your apache config. This can be found here: /etc/apache2/apache2.conf
sudo nano /etc/apache2/apache2.conf
CTRL-O to save, CTRL-X to exit in nano if you are not familiar with it.
DocumentRoot /var/www/ with
Copy your webfiles now to webroot.
sudo /etc/init.d/apache2 reload
Apache should now have restarted with all the configurations loaded.
This has created a directory in root called webroot, owned by apache2, and group owner is the new group webdev, which your user is now appended to member of (this does not replace any groups!). This will allow you to edit the files in the FTP!
This is a very simple solution for a one-website apache server. More work is required if you plan on running multiple sites (creating separate folders for them in webroot for example)
The advantages of this are that if someone does find a vulnerability, they are locked into the webroot folder, and not your home folder! Also if you ever needed to allow any more users to modify the site, you can add their user to the webdev group with
sudo usermod -a -G theirusername webdev
Hope this helps!
