#/etc/pam.d/vsftpd
session    optional     pam_keyinit.so    force revoke
auth       required     pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed
auth sufficient /lib64/security/pam_userdb.so db=/etc/vsftpd/virtual_user
account sufficient /lib64/security/pam_userdb.so db=/etc/vsftpd/virtual_user
account    include      password-auth
auth       required     pam_shells.so
auth       include      password-auth
account    include      password-auth
session    required     pam_loginuid.so
session    include      password-auth

这两行

auth sufficient /lib64/security/pam_userdb.so db=/etc/vsftpd/virtual_user
account sufficient /lib64/security/pam_userdb.so db=/etc/vsftpd/virtual_user

需在
