修改 /etc/vsftpd.conf, 加上或设置为以下配置:

用户 / 权限配置

/etc/vsftpd/vsftpd.conf

local_enable=YES  
pam_service_name=vsftpd
userlist_enable=YES

/etc/pam.d/vsftpd

/etc/vsftpd/user_list (vsftpd 默认读取的 user_list 路径)

# vsftpd userlist
# If userlist_deny=NO, only allow users in this file
# If userlist_deny=YES (default), never allow users in this file, and
# do not even prompt for a password.
# Note that the default vsftpd pam config also checks /etc/vsftpd/ftpusers
# for users that are denied.

vsftpd 默认的 pam 配置(/etc/pam.d/vsftpd.conf) 里的auth required pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed 会拒绝所有 /etc/vsftpd/ftpusers 文件里用户登录。
