Abstract: The configuration and management of database cluster based on physical host have the problem of complex configuration and poor flexibility. Virtualization technology combined with cluster system management makes the system management and resource construction more flexible and transparent. This paper presents Xen Server virtual platform and MySQL database cluster system based concept proof scheme. The performance of the system is analyzed by comparing with the testing data of MySQL 5.1 single server version. The solution proposed in this paper not only reduces the complexity of database cluster system deployment through using the rapid replication function of virtual platform, improves the flexibility of configuration, but also has higher performance advantage in concurrency and massive data processing compared to MySQL 5.1 single server version.

Key words: virtualization, distributed system, database cluster, virtual infrastructure
