Ubuntu – How to run a php file after installing LAMP in ubuntu 11.10

Your server is set to not follow symlinks. Add this line:

Options +FollowSymLinks -SymLinksIfOwnerMatch

to your http.conf. For more info: http://www.hackersgarage.com/symbolic-link-not-allowed-or-link-target-not-accessible.html

You will also need to add browse access for others to each folder, all the way up to /home/somekittens/Dropbox/Project/Joomla/. i.e.

sudo chmod o+x /home
sudo chmod o+x /home/somekittens
chmod o+x /home/somekittens/Dropbox
chmod o+x /home/somekittens/Dropbox/Project
chmod o+x /home/somekittens/Dropbox/Project/Joomla

It appears that you're running Apache 2.4; they changed the auth module between 2.2. and 2.4.

<Directory /home/alicia/Dropbox/Programing/PHP/intern-magnet/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    # Remove Apache 2.2 access controls
    #Order allow,deny
    #allow from all

    # Add Apache 2.4 access controls
    Require all granted
</Directory>

Other thoughts to consider: generally it is considered "best practice" to house your personal web development projects in ~/public_html, enable the usedir module a2enmod userdir, allow PHP to execute code there, and finally call the URL by browsing to http://localhost/~alicia/intern-magnet

Specific steps if you're interested in this tangent:

sudo a2enmod userdir
sudo $EDITOR /etc/apache2/mods-enabled/php5.conf
# Comment out lines "<IfModule mod_userdir.c> ... </IfModule>"
# This re-allows executing PHP code by users of your workstation, (presumably only you).
mkdir ~/public_html
ln -s ~/Dropbox/Programing/PHP/intern-magnet ~/public_html/intern-magnet
sudo service apache2 restart
# Develop and Profit!

Additional projects you start simply need their code linked to inside ~/public_html just like the above ln -s command, then browse to /~alicia/PROJECT_NAME_HERE!
