需求

 1）让用户可以使用FTP软件登录到网站，进行上传下载
2）但是他只能看到网站下的，不能超出网站目录！

安装

用的是vsftpd

 yum install vsftpd
systemctl start vsftpd
systemctl enable vsftpd

问题

按照网上说的 https://www.liberiangeek.net/2014/08/install-vsftpd-ftp-server-centos-7/ 配置vsftpd，修改了/etc/vsftpd/vsftpd.conf 重启结果一直报错：

 [root@niche vsftpd]# systemctl restart vsftpd
