When the guestname parameter in vsftp is set to the user to which nginx belongs, you cannot enter the specified local_root directory, but enter the home directory

in the virtual user configuration of vsftp, as long as guestname is set to the user to which nginx belongs, when ftp connects, it does not enter the directory set by the local_root parameter, but to the / home/nginx directory. Nginx users do not have a home directory.
but I changed it to a directory where mysql or ftp, the user to which vsftp belongs, can go to the local_root parameter settings normally.
