Problems solved by technology

However, the existing multi-center disaster recovery solution cannot determine the location of the failure, for example, it cannot determine whether the application cluster has failed or the database cluster has failed
Therefore, when a connection abnormality occurs in a data center, it can only be switched at the data center level

Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0044] Before introducing the embodiments of the present application, an application-level disaster recovery system based on multi-center deployment is introduced first, so that those skilled in the art can more easily understand the application scenarios of the embodiments of the present application. Such as figure 1 As shown, the system is deployed in multiple data centers. In order to clearly represent multiple data centers, data center 1, data center 2 ... data center N is used t...

Abstract

The present application provides an application-level disaster tolerant method and an application-level disaster tolerant system. The application-level disaster tolerant method is deployed at each data center, and comprises the steps of: determining that an abnormal connection of an application cluster occurs and pushes a notification that the abnormal connection of the application cluster occurs when a main control terminal of a HAProxy clustered system judges that number of application terminals having abnormal connection in the application cluster is greater than a first preset number; and determining that an abnormal connection of a database cluster occurs and pushes a notification that the abnormal connection of the database cluster occurs when a main control terminal of the application cluster judges that number of databases having abnormal connection in the database cluster is greater than a second preset number. The application-level disaster tolerant method and the application-level disaster tolerant system can achieve the purpose of accurately determining a fault position. Since the application-level disaster tolerant method and the application-level disaster tolerant system can accurately determine the fault position, the switching can be carried out at the fault position when switching the data center without switching the overall data center.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a multi-center-based system application-level disaster recovery method. Background technique [0002] In recent years, computer network systems have developed rapidly. However, due to natural disasters, equipment failures or human factors, etc., the loss of information and data of the computer network system and the interruption of business processing may occur, which will cause serious damage to the computer network system. Therefore, a data disaster recovery strategy is added to the current computer network system. The core idea of ​​the data disaster recovery strategy is to build multiple sets of parallel systems. When an unexpected situation occurs in one system, it can be switched to another system to ensure that the computer network system will not be affected. [0003] At present, one way to realize the data disaster recovery strategy is to have multiple data ...
