centos7，已经装好iptables，然后配置vsftpd如下：

local_root=/ftpfile

anon_root=/ftpfile

use_localtime=YES

anonymous_enable=NO

local_enable=YES

#

# Uncomment this to enable any form of FTP write command.

write_enable=YES

#

local_umask=022

dirmessage_enable=YES

#

# Activate logging of uploads/downloads.

xferlog_enable=YES

connect_from_port_20=YES

xferlog_std_format=YES

ftpd_banner=Welcome to mmall FTP Server

chroot_local_user=NO

chroot_list_enable=YES

# (default follows)

chroot_list_file=/etc/vsftpd/chroot_list

listen=YES

pam_service_name=vsftpd

userlist_enable=YES

#tcp_wrappers=YES

pasv_min_port=61001

pasv_max_port=62000

pasv_enable=YES

但启动的时候报错：
