Having read this EE manual entry:
http://ellislab.com/expressionengine/user-guide/installation/best_practices.html
And wanting to ideally place the system folder above the httpdoc folder on my server, I gave it a whirl, but alas it didn’t work.
I host my site on a MediaTemple DV 4.0 Site, so I did some searching and fortunately there is a work around.
Take a look at this excellent guide here:
http://www.prioninteractive.com/2011/01/storing-files-above-the-web-root-on-media-temple-dv/
And the related Wiki article here:
http://wiki.mediatemple.net/w/(dv)_4.0:Set_the_path_for_open_basedir
Please pay attention to this line:
Reconfigure your webserver so it will look for your new vhost.conf file by doing this:
/usr/local/psa/admin/sbin/httpdmng --reconfigure-domain examHope this helps any Mediatemple folks looking at more secure deployments.
All the best.
