METHOD AND SYSTEM FOR ACHIEVING A HIGH AVAILABILITY AND HIGH PERFORMANCE DATABASE CLUSTER

摘要

A method and system for implementing a high availability and high performance database cluster are disclosed. The method comprises: installing a distributed block device replication software, a high availability cluster component, and a dependent package of database multi-master software on a host and a backup machine; building a distributed block device replication software environment in the cluster for synchronizing data of the backup machine with the host; building a high availability cluster component environment in the cluster; building a database multi-master environment among nodes of the host, the backup machine and a slave; and defining a resource on the host and the backup machine so that the host and the backup machine are switchable to each other and the slave can access database services provided by the host and the backup machine to provide uninterrupted database cluster services.

1. A method for implementing a high availability and high performance database cluster, comprising:
A) installing a distributed block device replication software, a high availability cluster component, and a dependent package of database multi-master software on a host and a backup machine in the cluster; B) building a distributed block device replication software environment among the host and the backup machine in the cluster, so that the backup machine is capable of synchronizing its data with the host; C) building a high availability cluster component environment among the host and the backup machine in the cluster; D) building a database multi-master environment among nodes of the host, the backup machine and a slave in the cluster; and E) defining a resource on the host and the backup machine in the cluster, so that the host and the backup machine are switchable to each other and the slave is capable of accessing to database services provided by the host and the backup machine to provide uninterrupted database cluster services.
