首先说明一下，我是在虚拟机中装的Ubuntu14.04，物理机是Win10，最初只是为了在两个系统间传输文件才在Ubuntu中安装了ftp服务器，从Windows端登陆其即可。最初也是按照网上的各种教程来配置，结果就是喜闻乐见的各种报错不能用，或者说无法登陆等等。这里，分享一下我自己的配置过程，按照步骤来就没有问题。
我对ftp服务器的需求是：
不允许匿名访问，因为我不想其他机器随便都能登陆上来；锁定一个共享目录，在这个目录下我可以上传和下载文件，进行文件共享；不单独建立ftp用户，本机就可以访问；
好了，开始安装。
sudo apt-get install vsftpd
很快就可以安装完成。
接下来配置vsftpd.conf文件，位于etc目录下。
sudo gedit /etc/vsftpd.conf
更改相应的配置：
1、我不希望别人匿名登陆：
2、锁定一个共享目录：（自己指定一个文件夹就可以，我用的是/home/xhb/ftp）
3、本机可以访问：
4、允许写操作：
5、不单独建立ftp用户，直接使用Ubuntu桌面用户就可以登陆：
这里有用到/etc/vsftpd.chroot_list这个文件，没有就新建立一个：
sudo gedit /etc/vsftpd.chroot_list
在文件中填入允许登陆的账号名。（我的桌面用户名是xhb，也可以添加其他用户名）
然后配置接OK了。
完整配置文件（/etc/vsftpd.conf）：
# Example config file /etc/vsftpd.conf## The default compiled in settings are fairly paranoid.

现在重启FTP，让之前的配置生效。
sudo service vsftpd restart
到这里就OK了。登上去看看。
首先，查看IP地址。
我的本地IP地址是192.168.139.135。
在Windows资源管理器中输入：ftp://（你的IP地址）
输入账户名和密码后即可登录了。
登录的路径就是设为共享文件夹的那个路径。
备注：
如果出现无法登录的情况，原因可能是这样：
之前在配置时，我们做了如下配置来指定允许登陆的用户：
提出来看看：
chroot_list_enable=YES chroot_list_file=/etc/vsftpd.chroot_list
配合使用，使得只有在vsftpd.chroot_list中配置的用户才能登录FTP。
然而vsftpd.chroot_list中配置的用户，对于local_list指定的目录不允许有些的权限。
所以对于共享目录不能有写的权限，如果有我们必须把它去掉。
查看ftp目录的权限。
ls -l
去掉写权限。
chmod u-w,g-w ftpls -l
从显示信息的最前面可以看到，ftp的写权限已经去掉了。接下来就可以正常登陆了。
