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
Job for vsftpd.service failed. See 'systemctl status vsftpd.service' and 'journa
lctl -xn' for details.
[root@niche vsftpd]# systemctl restart vsftpd.service

[root@niche vsftpd]#
出现错误的原因是：由于centos7中vsftp的配置文件默认将 listen_ipv6=YES 这一行没有注释掉，而我们目前的网络环境还不支持ipv6，从而导致出现错误无法启动，所以解决方法是将 listen_ipv6=YES更改为：listen_ipv6=NO，或将这一行注释掉
按上面的方法注释掉 listen_ipv6=YES后，成功启动vsftp
