Cluster system, service access method, device and server

Abstract

The invention discloses a cluster system, a service access method, an apparatus, a server and a computer-readable storage medium. The system includes: a cluster deployment management platform, a global configuration distribution center, a front-end server, and multiple consistent system service units; wherein, the cluster deployment management platform is used to manage the multiple consistent system service units and service address information and corresponding service port information; the global configuration distribution center is used to maintain the access routing table, and the access routing table includes the routing information between the tenant and the consistency system service unit group; the front-end server is used to obtain all The access routing table is received, the access request from the tenant is received, and the access request is forwarded to the corresponding consistency system service unit according to the access routing table. In order to reduce the access cost of the consistent system service unit, the smooth migration of tenant data is realized.

Description

technical field [0001] The present invention relates to the technical field of distributed clusters, and more specifically, to a cluster system, a service access method, a service access device, a server, and a computer-readable storage medium. Background technique [0002] The consistency system service unit is implemented based on the consistency protocol, and usually exists in the cluster as a basic distributed coordination service unit, providing highly reliable service discovery, distributed locks, and access services such as metadata reading and writing. [0003] Commonly used methods for accessing consistent system service units are as follows: figure 1 As shown, a separate DNS access domain name is packaged for each consistent system service unit. When multiple consistent system service units need to be used, the application needs to maintain a series of DNS access domain names and access them by looking up specific DNS access domain names. The associated consistent...

Problems solved by technology

[0005] However, the disadvantages of this solution are also obvious: First, there is an upper limit on the capacity of the consistent system service unit. With the rapid development of business, the application program will need more and more consistent system service units, and the consistent system service that needs to be maintained naturally The domain name list of the unit will also continue to increase, bringing higher access costs; the second is service sharing based on the tenant mechanism, that is, the isolation and protection of access resource paths. When the number of visits of a single tenant increases rapidly, shared services will be affected Users of other tenants of the unit; third, for a shared consistent system service unit, tenant-based data migration is relatively difficult, and there are dual challenges of service availability and data consistency
