vsftpd一键安装配置脚本，可配合 lnmp1.0 使用(为lnmp1.0而扩展编写)。

接受用户输入ftp指定的用户名密码，可锁定用户家目录为nginx站点默认根目录，比如/usr/local/nginx/html 。在开启iptables服务时，需手动修改iptables，放行21、30000到30100端口。

如果作为单独安装，需要修改：
#useradd -s /sbin/nologin vuser
去掉前面注释
echo guest_username=www >> vsftpd.conf
www改为vuser
chown -R www:www $dire
www:www改为vuser:vuser
