I would like to know how to prevent directory listings in Apache2 on debian7.
For example, I am able to view the contents of a folder called “test.php” that created inside /var/www. I don’t want visitors to be able to view the contents of directories.

For the apache2.conf file , I have changed the

<Directory “/var/www”>
Options Indexes FollowSymLinks
IndexOptions FancyIndexing FoldersFirst IgnoreCase VersionSort NameWidth=*
</Directory>

into

<Directory “/var/www”>
Options FollowSymLinks
</Directory>

and set
<Directory /var/www/test>
Options -Indexes
</Directory>

It is no use to restart my apache2 ,the test.php file in the /var/www still be viewed by others when to input my vps_ip in firefox .
