参考文档：https://cloud.tencent.com/document/product/213/10912；

遇到的坑：按照教程来搭建，但一直显示无法连接，或者无法获取目录；

特别注意：

> > 1.  关闭selinx,   防火墙；
> > 2.  特别注意：vsftp的服务权限和linux的目录权限；
> > 3.  限制用户的根目录：chroot\_list\_enable=NO,chroot\_local\_user=YES(所有用户均不能切换到其他目录)
> > 4.  FTP 协议在腾讯云网络架构上的不适，FTP 客户端默认被动模式传输。提前把主动模式，添加上；  
> >     
> > 5.  如果之前连接失败，最好把保存的ftp连接账号、密码删除，重新填写；
> > 6.  ’每次更改核心配置文件vsftp.conf，切记一定要重启vsftpd服务；
> > 
> > 配置文件示例：
> > 
> >     # Example config file /etc/vsftpd/vsftpd.conf
> >     #
> >     # The default compiled in settings are fairly paranoid. This sample file
> >     # loosens things up a bit, to make the ftp daemon more usable.
> >     # Please see vsftpd.conf.5 for all compiled in defaults.
> >     #
> >     # READ THIS: This example file is NOT an exhaustive list of vsftpd options.
> >     # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
