解决方法
似乎有人已经修改了你的umask,因为根据vsftpd man文件,默认值为776.检查你的配置以获取以下值并进行相应调整.
file_open_mode
The permissions with which uploaded files are created. Umasks are applied on top of this value. You may wish to change to 0777 if you want uploaded files to be executable.
Default: 0666
local_umask
The value that the umask for file creation is set to for local users. NOTE! If you want to specify octal values,remember the “0” prefix otherwise the value will be treated as a base 10 integer!
Default: 077
