命令:yum -y install vsftpd

 之后开启服务:service vsftpd start

    1) 重启后生效

        开启: chkconfig iptables on

        关闭: chkconfig iptables off

    2) 即时生效,重启后失效

        开启: service iptables start

        关闭: service iptables stop

首先找到vsftp的配置目录

[root@localhost vsftpd]# pwd

/etc/vsftpd

[root@localhost vsftpd]# ls

chroot_list  ftpusers  user_list  vsftpd.conf  vsftpd_conf_migrate.sh

[root@localhost vsftpd]#

修改

[root@localhost vsftpd]# cat ftpusers

# Users that are not allowed to login via ftp

#root

bin

daemon

adm

lp

sync

shutdown

halt

mail

news

uucp

operator

games

nobody

修改

[root@localhost vsftpd]# cat user_list

# 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.

#root

bin

daemon

adm

lp

sync

shutdown

halt

mail

news

uucp

operator

games

nobody

上面这个两个就是默认情况下vsftp不允许使用的账号列表，讲文件中root删除，或者前面加个#号 重启一下vsftpd 服务 即可
