The Improvement Of RIS Accuracy And Fault-Tolerance Under Linux

For recent years with IT estate developing at highly speed; the computer application has expanded into many industries. Computer gradually plays more and more important role in people's work and life. With the expansion of enterprise scale and the application of distributed system, more and more enterprises have confronted the problems about computer software installation and the administration. The problem the network administrator in the face of is how to deploy the internal computers of enterprise quickly and accurately.The thesis sets forth RIS (Remote Install System) deployment principle and analyzes the deficiency of deploying products at present, designs and carries out the remote deployment system with high accuracy and high fault-tolerance. Entire system abides by C/S design architecture; it is composed by two parts: the server and the client. The server mainly provides deployment operations for administrator. The client who is in charge of executive remote deployment operations is the remote deployment executor.In the light of this system characterization-high accuracy and high fault-tolerance, it is provides a detailed introduction of the design and fulfillment of some pivotal modules like the operate system installation module and software deployment module and simply introduces the design of the system and classes. In the remote installation OS module, adopt the Frame Buffer programming technology combine with custom-made OS surveillance on systematic installation process , have improved the accuracy and fault-tolerance of the remote installation OS. In the software deployment module, adopt version control method avoid overlap install and version diversity; have improved the accuracy and fault-tolerance of the software deployment.
