Can not Add user to vsftpd? Have a look at pam_service

1) Check in /etc/vsftpd/vsftpd.conf
pam_service_name=???

2) Check pam config in /etc/pam.d/???
Eg:
auth required     /usr/lib64/security/pam_userdb.so db=/etc/vsftpd/vsftpd_login
account required  /usr/lib64/security/pam_userdb.so db=/etc/vsftpd/vsftpd_login

3) Check user config to set home directory at /etc/vsftpd/vsftpd.conf
user_config_dir=/etc/vsftpd/vsftpd_user_conf/
then
add new user:
useradd your_new_user
seting password:
passwd your_new_user
also append that user and password to /etc/vsftpd/logins.txt
your_new_user
your_new_password
set FTP default folder:
vim /etc/vsftpd/vsftpd_user_conf/your_new_user
local_root=/your_path

4) Regenerate user list db file
db_load -T -t hash -f /etc/vsftpd/logins.txt /etc/vsftpd/vsftpd_login.db

5) Restart vsftpd
systemctl restart vsftpd
