Personally, I would not configure the shared Drupal code-base as an actual "Website" (unless you require end-user [as opposed to root] FTP/sFTP access to the files). Instead, I would install Drupal to /usr/share/drupal or similar.

if not configure the shared drupal codebase as an actual website, then how to install the codebase site and configure it by login to the site? use http://localhost for this?

Then, all you should need to do is add the necessary shared Drupal directories to PHP's open_basedir directive for each site (Home -> Sites -> [domain.tld] -> Options [tab]). Here's an example of adding the necessary Roundcube directories to the open_basedir directive in order for users to be able to access Webmail from a given virtual host:

do you mean add to "Apache directives" text field under Options tab? is this equivalent to edit httpd.conf? or .htaccess file?

<Directory /var/www/domain.tld/web/>
php_admin_value safe_mode off
php_admin_value register_globals off
php_admin_value magic_quotes_gpc off
php_admin_value display_errors off
php_admin_value upload_tmp_dir "/var/www/clients/client2/web1/tmp"
php_admin_value open_basedir "/tmp:/etc/roundcube/:/usr/share/roundcube:/var/log/roundcube:/var/lib/roundcube:/var/lib/roundcube/skins:/var/lib/roundcube/skins/default/templates:/var/lib/roundcube/plugins:/var/lib/roundcube/config:/var/lib/roundcube/bin:/var/lib/roundcube/program:/var/log/roundcube:/usr/share/php:/usr/share/pear:/var/www/clients/client2/web1/web:/var/www/clients/client2/web1/tmp"
</Directory>

is "php_admin_value open_basedir "/tmp:/etc/roundcube/:/usr/share/roundcube:/var/log/roundcube:/var/lib/roundcube:/var/lib/roundcube/skins:/var/lib/roundcube/skins/default/templates:/var/lib/roundcube/plugins:/var/lib/roundcube/config:/var/lib/roundcube/bin:/var/lib/roundcube/program:/var/log/roundcube:/usr/share/php:/usr/share/pear:/var/www/clients/client2/web1/web:/var/www/clients/client2/web1/tmp"
" equivalent to the content in the "PHP open_basedir" field under Options tab?
