LinuxQuestions.org - open_basedir enabling for exiting websites

Hi, i want to add a open_basedir line to my apache configurations file.

I want to add this line.

php_admin_value open_basedir "/chroot/home/$USERNAME/:/usr/share/pear/:/tmp/:/var/lib/php/session/"

My configurations file located on : /etc/httpd/conf.d

Conf file prefix vhost_***.conf

Sample conf file.

Code:

<VirtualHost 77.79.92.21:80>
