Create one group and two Linxu accounts. The group name is ftpgrp. The two accounts are ftpuser and ftpadmin respectively. Then grant the FTP directory permission to ftpadmin. The directory I use is/home/ftp with the command: chown ftpadmin: ftpgrp/home/ftp.
Then create a virtual account:Pure-pw useradd sweet-u ftpadmin-d/home/ftp # Here I add myself

The idea of online registration and file upload is to use web forms to collect user-filled information and store it in the Mysql database, at the same time, create an FTP upload account with the user's Registration Name and create the corresponding directory for the user.
By default, the Ftp server uses the user name and password of the System user. Creating a system user is equivalent to creating an FTP user. FreeBSD is a UNIX operating system, it does not have user and group creation commands
