Apache2 disable directory listing

Step 1: The best way to do this is disable it with webserver apache2. In my Ubuntu 14.X - open /etc/apache2/apache2.conf change from

Sample

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

to

<Directory /var/www/>
        Options FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>
