目录权限

ftp服务器的根目录必须是755，不能是777权限，权限太大，而且用户属主必须是 root

1
2
chmod 755 /var/ftp
chown root:root /var/ftp

匿名用户可以操作的目录，需要在 ftp 根目录下创建一个上传目录

3
mkdir /var/ftp/pub
chmod 777 /var/ftp/pub
chown ftp:ftp /var/ftp/pub

认证

登录 FTP 有三种方式

匿名登录：在登录FTP时使用默认的用户名，一般是ftp或anonymous

本地用户登录：使用系统用户登录，/etc/passwd 中的用户。

虚拟用户登录：FTP 专有用户，两种方式实现虚拟用，本地数据文件和数据库服务器

本地数据文件

一行用户名，一行密码。奇数行为用户名，偶数行为密码。
