Load balancing method and device based on DNS fixed distribution virtual ip

Abstract

The invention discloses a load balancing method and device based on DNS fixed distribution virtual ip, a back-end server and a computer readable storage medium. The method comprises the steps of enabling preset nodes to collect respective corresponding current virtual ip; updating respective stored virtual ip according to the current virtual ip, and respectively providing services for respective corresponding target clients, wherein the target clients are clients accessing the virtual ips stored in the preset nodes respectively. Thus, the current virtual ip corresponding to the preset node isacquired through the preset node; the virtual ip stored by each server is updated; updating of the stored virtual ip by the back-end server without faults and after the faults are repaired can be realized; therefore, the influence of failure and recovery of the back-end server in the distributed file system on service provision is reduced, the client request processing efficiency of the back-end server is improved, the network data processing capability is further enhanced, and the flexibility and availability of the network are improved.

Description

technical field [0001] The present invention relates to the technical field of distributed file systems, in particular to a load balancing method, device, back-end server and computer-readable storage medium based on DNS fixed allocation of virtual IP. Background technique [0002] With the development of science and technology in modern society, the application of distributed file system is more and more extensive. [0003] In the prior art, the load balancing strategies in the distributed file system include round robin, weighted round robin, minimum number of connections, random, source address hashing, etc. The minimum number of connections, random or source address hash method, allocate back-end servers to achieve the purpose of load balancing; the load balancing strategy will assign a back-end server to the client to provide services, when the back-end server fails, the client The end will obtain the services of other back-end servers, causing the back-end pressure to...

[0003] In the prior art, the load balancing strategies in the distributed file system include round robin, weighted round robin, minimum number of connections, random, source address hashing, etc. The minimum number of connections, random or source address hash method, allocate back-end servers to achieve the purpose of load balancing; the load balancing strategy will assign a back-end server to the client to provide services, when the back-end server fails, the client The end will obtain the services of other back-end servers, causing the back-end pressure to be redistributed. When the back-end server fails and recovers, the client cannot continue to obtain the services of the back-end server, which will cause a waste of server resources and reduce the back-end The efficiency with which the end server handles client requests
