【摘要】：随着计算机硬件技术的不断发展、用户对传统PC使用方式的不断改进,桌面虚拟化技术逐渐被人们所认知。用户访问自己的虚拟PC,可以如同操作传统PC一样简单方便,轻松的使用各种硬件资源和网络资源。然而不容忽视的一点是,这一重要的变革在给我们带来了便捷和舒适的使用体验的同时,还是存在着一些显著的问题。用户在使用虚拟主机之时,数据的存放位置仍然为虚拟主机所在的服务器公有存储中,也就是说,用户对自己的数据是无法进行管理的,这就存在着数据可视性和管理安全性的问题。在当今这样一个以数据安全为中心的信息化社会,解决数据的安全性和隐私性问题成为用户最关心最迫切需要的需求。本文首先针对上述的问题进行了研究和分析,提出并实现了一种混合云架构的公私混合存储系统。基于虚拟化的云桌面环境,以XenServer虚拟化服务器为依托,结合XAPI和自主搭建的FTP文件缓存服务器,采用MYSQL、Socket、FTP等计算机技术,设计并实现一种公私混合存储系统。在系统的客户端模块中,用户可以进行注册登录操作,并探测当前环境下的私有存储设备信息,输入VM参数进行初始化。通过客户端与服务器端的连接,可以对存放在XenServer公共存储区域上的用户虚拟机数据进行管理,将用户数据迁移到私有存储区域中,当用户再次上线时,可以将用户数据从私有存储区域中迁移回虚拟机中。同时,还可以进行数据动态监控,在用户离线时,将数据备份至私有存储中,保证了用户对自己数据的可见性和数据保存的安全性。最后,通过实际搭建应用环境进行系统地有效地测试分析,保证了系统的有效性和可靠性。
[Abstract]:With the development of computer hardware technology and the improvement of traditional PC usage, desktop virtualization technology is gradually recognized by people. Users can access their own virtual PC, as simple and convenient as traditional PC, easy to use a variety of hardware resources and network resources. However, it can not be ignored that this important change has brought us a convenient and comfortable experience, but there are still some obvious problems. When a user uses a virtual host, the location of the data is still in the public storage of the server where the virtual host is located, that is, the user cannot manage his data. There are problems of data visibility and management security. In today's information society with data security as the center, solving the problem of data security and privacy has become the most urgent need of users. In this paper, the above problems are studied and analyzed, and a hybrid storage system based on hybrid cloud architecture is proposed and implemented. Based on virtualized cloud desktop environment, based on Xen Server virtualization server, combined with XAPI and FTP file cache server, this paper designs and implements a kind of public and private hybrid storage system by using MySQL SQL socket FTP and other computer technologies. In the client module of the system, the user can register and log on, detect the information of the private storage device in the current environment, and input the VM parameters to initialize. Through the connection between the client and the server, the user virtual machine data stored in the Xen Server public storage area can be managed, the user data can be migrated to the private storage area, and when the user is online again, You can migrate user data from a private storage area back to the virtual machine. At the same time, the data can be monitored dynamically. When the user is offline, the data can be backed up to private storage, which ensures the user's visibility of his data and the security of data preservation. Finally, the validity and reliability of the system are ensured by the practical application environment.
