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.
