This guide explains how you can use mod_mysql_vhost to create simple
virtual hosts on a lighttpd web server on Debian Etch. With
mod_mysql_vhost, lighttpd can read the vhost configuration from a MySQL
database. Currently, you can store the domain and the document root in
the MySQL database which results in very simple virtual hosts. If you
need more directives for your vhosts, you’d have to configure them in
the global section of lighttpd.conf, which means they’d be valid for
all vhosts. Therefore, mod_mysql_vhost is ideal if your vhosts differ
only in the domain and document root.
