404 Not Found Error when trying to access localhost on local LAMP server

I'm running Ubuntu. My Apache2 default file looks like this:

<VirtualHost *:80>
        ServerAdmin webmaster@localhost

        DocumentRoot /var/www/
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

I have this file called Index.php in /var/www/

<?
phpinfo();
?>

When I access http://localhost/ in my browser, I'm getting the 404 Not Found error:

The requested URL / was not found on this server. Apache/2.2.16 (Ubuntu) Server at localhost Port 80

What am I doing wrong? This actually worked when I first setup LAMP but it's not working now.

Have a look in /etc/apache2/sites-enabled. It seems like my upgrade to 10.10 has wiped the symlinks from that directory. Try symlinking default to /etc/apache2/sites-available/default

sudo ln -s /etc/apache2/sites-available/default /etc/apache2/sites-enabled/default

Check out error log (tail /var/log/apache2/error.log) in order to find out exact path that Apache tries to find.

Exactly the same problem with me.

Following worked for me :

As Andreas Jansson mentioned, symlink default to:

sudo ln -s /etc/apache2/sites-available/default /etc/apache2/sites-enabled/default

and restarted apache2:

sudo /etc/init.d/apache2 restart

and then it works:

http://localhost/

Use the url localhost/info.php. File info.php must contain <?php phpinfo(); ?>

Do you have the PHP module installed and enabled? Because, normally, it would mention that in the server signature, but yours doesn't. That would also explain why the server doesn't recognize that index.php is what you mean by /.

Try

sudo a2enmod php5
