Pure-FTPd is a free (BSD), secure, production-quality and standard-conformant FTP server which is actively supported and designed with security in mind. It focuses on efficiency, ease of use and provides simple answers to common needs, plus unique useful features for personal users especially on Linux VPS servers as well as hosting providers. Pure-FTPd can even run 100% non-root, with its built-in chroot() emulation and virtual accounts.
In this tutorial we will show you how to configure Pure-FTPd so that it uses virtual users from a MySQL database instead of real system users. This configuration is much more performant and will allow you to have thousands of FTP users on a single server.
