【摘要】：随着信息技术的发展和网络存储技术的完善，出现了一种新的存储技术—云存储技术。云存储以其随时随地访问的便捷性，按需使用的灵活性，极低的管理成本吸引着越来越多的人使用。公有云的数据绝大多数都是由专门负责提供云服务的服务商存储和管理。目前，部分企业考虑到数据的安全性，已在企业内部提供了私有云服务来满足自身存储需求和降低企业维护开销。然而，作为个体的家庭用户同样需要将自己的私有数据进行保存或者与家人分享，针对家庭用户的私有云系统便有其存在的价值。根据家庭用户所具有的特点，系统应该建立在嵌入式设备上，而且需要设计一种安全的私有云系统以保证个人数据的安全性和可靠性。整个系统由两部分组成，一个是服务器，主要是一个由vsftpd作为基础的FTP文件服务器，通过对vsftpd的配置，可以有效限制用户的权限以及活动的主目录，从而让用户的操作限定在适当的范围里，这样就保证了整个服务器的安全性和可靠性。另一个是客户端，鉴于目前占市场份额较多的手持终端操作系统是Android，通过对Android客户端的设计，实现了三个核心模块，包括登录模块、下载文件模块、上传文件模块。通过客户端家庭用户能方便的上传文件到私有云服务器上，下载私有云服务器上的文件到手持终端。最终，，整个系统通过在虚拟机上部署vsftpd服务器，通过配置文件限制用户的权限和主目录，并在手持终端安装客户端，能够实现文件安全和可靠地上传和下载。
[Abstract]:With the development of information technology and the improvement of network storage technology, there is a new storage technology - cloud storage technology. Cloud storage is easy to access at anytime and anywhere, the flexibility to use, and very low management costs attract more and more people to use. The vast majority of the data of the public cloud are specially responsible for providing cloud clothes. Service providers store and manage. At present, some enterprises, taking into account the security of data, have provided private cloud services within the enterprise to meet their own storage needs and reduce enterprise maintenance costs. However, as individual home users, it is also necessary to save or share their private data with their family, for family users. The private cloud system has its value.
According to the characteristics of home users, the system should be built on embedded devices, and a secure private cloud system should be designed to ensure the security and reliability of personal data. The whole system is composed of two parts, one is a server, mainly a FTP file server based on vsftpd, through the vsftpd Configuration, can effectively limit the user's rights and active directory, so that the user's operation is limited to the appropriate scope, thus ensuring the security and reliability of the entire server. The other is the client, given the current market share of the handheld terminal operating system is Android, through the Android client. Three core modules, including login modules, downloading file modules and uploading file modules, can be easily uploaded to private cloud servers by client home users, and files from private cloud servers are downloaded to handheld terminals.
Finally, by deploying vsftpd servers on the virtual machine, the whole system restricts the user's rights and main directories by configuring files, and installs the client on the handheld terminal, enabling the file to be uploaded and downloaded safely and reliably.
