Realization way of dual-active system based on consistency algorithm

The invention relates to the technical field the database, and discloses a realization way of a dual-active system based on a consistency algorithm. The realization way comprises the following steps:(1) deploying a first computing server, a first storage server and a second storage server in a first data center, deploying a second computing server, a third storage server and a fourth storage server in a second data center; (2) managing the second storage server and the third storage server by using a consistency algorithm program; (3) setting a weight value in a configuration file of the consistency algorithm program; and (4) when an optical fiber link connected between the first data center and the second data center is in sending fault, performing cluster split brain on the dual-activesystem, performing decision-making by the consistency algorithm program according to the weight configured in the step (3) , and stopping the service of the data center with small weight.
