基于Hadoop的云计算试验平台搭建研究

Hadoop是一个免费的开源云平台，是允许在集群计算机上分布式处理大数据的软件框架。它是一种可靠、高效、可伸缩的云平台，很适合在实验室环境下进行模拟测试。以Hadoop为基础，借助虚拟机VMware以及Linux、ubuntu、Hadoop、java--jdk等软件，详细地介绍了单机环境下的虚拟云平台搭建过程，并给出具体的实例搭建过程。在设计实例中详细的论述了虚拟机、java、Hadoop等软件的安装、设置、测试过程。实现了在实验室环境对云平台的虚拟，并提出了在搭建试验平台时应该注意的用户权限、路径配置和使用SSH服务程序等问题。该试验平台为系统中间件和应用服务的开发提供了基础。

On construction of experiment platform of Hadvop based cloud computing

Hadoop is a free open source cloud platform, which is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is a reliable, efficient, scalable cloud platform, is very suitable for simulation test in laboratory environment. In this paper, with the help of some software such as virtual machine VMware, Linux, ubuntu, Hadoop, java-jdk, the building process in the stand-alone environment of virtual cloud platform was described in detail based on the Hadoop. The building process of virtual cloud platform in a specific example was also elaborated. It was described that how to install Hadoop and java and how to set up in detail. It completed the experiment environment, and point out that some problem must be paid attention during the building process, such as example for user right, path configuration and using of SSH service program. This experimental platform provides the basis for the development of system middleware and application service.
