Distributive database service management system

Abstract

Proposed is a distributed database service management system. The system comprises a master control node and at least one data node, wherein the master control node can manage a database service instance operated on the at least one data node based on a command from a user and / or a configuration file, receive a database access request from an external application, and transmit the received database access request to a target database service instance subsequently, so as to execute a requested database service. The distributed database service management system disclosed in the present invention can realize the high usability of a database service and can satisfy the actual requirements of migration of various databases.

Description

technical field [0001] The present invention relates to a database service management system, more specifically, to a distributed database service management system. Background technique [0002] At present, with the increasingly wide application of computers and networks and the increasing variety of businesses in different fields, the management of distributed database services based on cloud computing is becoming more and more important. [0003] Existing database service management systems usually store database service instances and database data in local disks of distributed servers, and bind their IP addresses to physical machines after database service instances are created, so as to realize external applications’ access to database services. Instance access. [0004] However, the existing technical solutions have the following problems: (1) Since the database service instance and database data are stored in the local disk of the distributed server, it is difficult ...

Problems solved by technology

[0004] However, the existing technical solutions have the following problems: (1) Since the database service instance and database data are stored in the local disk of the distributed server, it is difficult to achieve the high availability requirements of the database service (that is, lack of (2) Since the IP address of the database service instance needs to be bound to the physical machine after the database service instance is created, the physical machine where the database resides needs to be maintained and migrated The database needs to change the IP address of the database service instance, which makes it difficult to adapt to various actual needs (for example, in a private cloud-based system, it is usually necessary to use the IP address as a connection parameter)
