In the document http://doc.ez.no/eZ-Publish/Technical-manual/5.x/Installation/Normal-installation/Installing-eZ-Publish-on-a-Linux-UNIX-based-system it refers that it's possible to install eZ Publish 5 using the following methods Document root example, Home directory example and Virtual host example.
However the Document root example and Home directory example don't work. If you try to make an installation accessing web/index.php/ezsetup you'll be stuck in the first screen and every time you press next the same page is loaded.
