Vsftp allows you to upload, download, and delete permissions only.

Vsftpd has special restrictions on each user.
You just need to create a setting file for that user, and then set it in the file

Add vsftpd. conf
User_config_dir =/etc/vsftpd/vsftpd_user_conf
Create a new file in this folder, which is the same as the user name. vsftpd compares the user name with the user name setting file.
