Abstract:

This paper analyses existed implementations of Load Balancing through Linux Virtual server, and put forward to design an authentication-based cluster building method based on Linux virtual server. In the existing methods of load balancing based on LVS, it is necessary to configure the IP and port numbers corresponding to the specific services in the scripts. In addition, the information needed for the services running on each real server should be configured on the real server. In this paper, a real server is used to obtain a copy of the secret information on the load scheduler by using the authentic server. In addition, the load scheduler can automatically generate the configuration file to solve the cumbersome configuration. In this way, The problem which Sensitive information have multiple copies will be solvedand then to build a highly available cluster system.

Key words: Linux virtual server, cluster, smart card, authentication, join dynamically
