Example Embodiment

[0022] The method for constructing a two-layer redundancy architecture of a virtualized cluster of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] At present, the existing server clusters are mostly built with physical host servers, which not only greatly wastes existing server resources such as CPU and memory, but also fails to better meet the operability requirements of computer room administrators. By building a virtualized operating platform on a physical server, not only the visual management of the physical server cluster is improved, but also the virtualized operating platform construction method can be further improved to realize the redundancy of the dual or even multiple virtualized operating system. Hot Standby.

[0024] Such as figure 1 , figure 2 As shown, a method for constructing a two-layer redundant architecture of a virtualized cluster is as follows:

[0025] 1) Hardware construction: Build a two-layer...

Abstract

The invention provides a construction method of a virtual cluster double-layer redundancy framework, which comprises the following specific steps that hardware is constructed: the virtual cluster double-layer redundancy framework based on a hardware server platform is constructed, and normal environment running is ensured, wherein the hardware server platform comprises two hardware servers with the same CPU (Central Processing Unit) model, and an external hanging memory; a virtual operating system is constructed; the two hardware servers mutually detect whether the other party is down; if so, an application on the down hardware server automatically transfers to the good server for running; and if not, the two hardware servers continue to detect whether the other party is down until a database can work normally and data is intact, and then the construction of the whole redundancy framework is accomplished. Compared with the prior art, the construction method of the virtual cluster double-layer redundancy framework realizes double-layer redundancy hot standby of a physical layer of the hardware and a virtual layer of software, saves physical resources, improves the safety of a whole application environment, and is high in practicability and easy to popularize.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for building a double-layer redundant architecture of a virtualized cluster with high information security performance. Background technique [0002] With the vigorous development of international informatization, the application of high-performance server clusters has reached an unprecedented stage, and different configurations of physical hardware server clusters have been realized through different network connection models. However, as people pay more attention to resource utilization, this kind of pure entity high-performance server cluster has also exposed its disadvantages—the resource utilization rate is too low, and the overall fitting planning of resources cannot be carried out in the actual application environment. [0003] Since the virtualization environment can integrate and reuse hardware resources, more and more application environments are applied to t...
