zend docroot不会改变

Just now I have start with zend framework, I have succesfully install zend framework, I followed the quick start guide I am stuck with doc root.

Short description of what I have done

1) Install lamp and zend framework

2) cd /var/www

3) zf create project quickstart

4) cd quickstart/library/

5) ln -s /usr/share/php/libzend-framework-php/Zend .

6) vi /etc/apache2/apache2.conf

<VirtualHost *:80>
    ServerName zend.gworks.mobi
    DocumentRoot /var/www/quickstart/public

    SetEnv APPLICATION_ENV "development"

    <Directory /var/www/quickstart/public>
        DirectoryIndex index.php
        AllowOverride All
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

note: also I tried with /etc/apache2/sites-enabled/000-default.conf but no luck

7) service apache2 restart

But still my browser point /var/www/html/index.html not /var/www/quickstart/public/index.php, I'm out of ideas. can anyone help me what I miss?

Solution (update)

I did right. when I restart vagrant, document root problem got solved, I don't know why it is not work previosly. but it throws .htaccess: Invalid command 'RewriteEngine' then I run this command sudo a2enmod rewrite && sudo service apache2 restart now it shows zend framework welcome page

You need to edit /etc/hosts file and add below line then do apache2 restart..
