Embodiment Construction

[0047] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0048] Such as figure 1As shown, a distributed database high-availability system based on a cluster manager includes several database groups 100, distributed database proxy middleware 200 and application system 300; each database group 100 is provided with a database master node 101 And database slave node 102, distributed database proxy middleware 200 comprises main proxy server 201 and from proxy server 202; Said main proxy server 201 connects 101 with the master node of each database group by main connection, connects with each database group by slave connection The slave node 102 is connected; the proxy server 202 is connected with the slave node 102 of each database group through the master connection, and is c...

Abstract

The invention relates to a distributive database high-availability method and system based on a cluster manager. Each database is assembled with a main node and a sub node; distributive data agency middleware is deployed onto a main agency main server and a sub agency sub server; the main agency server is connected with the main node of each database group through a main connector and is connected with the sub node of each database group through a sub connector, the sub agency server is connected with the sub node of each database group through a main connector and is connected with the main node of each database group through a sub connector, a main cluster manager is arranged in the main agency server, a sub cluster manager is arranged in the sub agency server, the main cluster manger supervises the agency process of the main agency server, the sub cluster manager supervises the agency process of the sub agency server, and the mutual monitoring is realized between the main cluster manager and the sub cluster manager. The method and the system provided by the invention have the advantages that the safety of the distributive database system is improved, the single-point fault problem is avoided, and the easy-to-use performance of the system is improved.

Description

technical field [0001] The invention relates to the field of distributed databases and cloud computing, in particular to a cluster manager-based high-availability method and system for distributed databases. Background technique [0002] In many key fields such as the Internet and telecommunications, with the continuous development of enterprise business, the I / T environment of enterprises is also constantly evolving. It is difficult for a single database to meet the requirements of massive database storage and high concurrent data access. The emergence of distributed databases has become Inevitably, distributed databases can effectively solve massive data storage and concurrency problems. Through horizontal alignment of data and vertical segmentation of data tables, massive data storage is effectively alleviated, and high Concurrency issues. However, since the distributed database is deployed on multiple nodes, when one node fails, the entire system may be at risk of being...
