Method for ensuring service availability of server management system

Abstract

The invention provides a method for ensuring service availability of a server management system. The method is characterized in that hierarchical model simplification usability evaluation is adopted to evaluate the service availability; the availability among service, a computing resource and a storage resource in the server management system has a dependency relationship; the availability of the service depends on the availability of the other three; only the three are available, the service can be health and available; the deployment of the service directly depends on the server management system, which is in the running state of the service detected by users; the situation that whether the service can be normally provided or not directly depends on the computing resource and the storage resource; a high-availability HeartBeat system is responsible for the invalidation switch of the two resources; and the state of the service directly depends on the availability of the server management system. The method only evaluates the availability after the deployment of the service is successful. The method can respectively evaluate the availability of the computing resource and the storage resource, and evaluates the availability of the service on the basis of the evaluation of the two sources; and all services are combined in a tandem mode by a computing resource module and a storage resource system.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a method for ensuring service availability of a server management system. Background technique [0002] For some applications that rely on the services on the system, whether the services on the server management system are running normally and whether the application resources of the services can be used have become the research focus of high-availability modules in the IT industry. How to realize the sustainable use of important user functions Supplying and realizing service failure is to switch in time and become the realization point of the present invention. [0003] At the present stage, the high-availability field, especially the various monitoring mechanisms of some services customized on openindiana, mainly has the following shortcomings: [0004] 1. Although the high-availability software HeartBeat solves the host switching function when the service host crashes, t...

Problems solved by technology

[0004]1. Although the high-availability software HeartBeat solves the host switching function when the service host crashes or the system crashes, when the host server fails due to the software itself When a certain service (such as ftp, smb service) goes down, the backup host cannot monitor and take over the service, so the timely switching function of the service cannot be realized;

[0005]2. It is a difficult concept in the industry to effectively evaluate the health status of the current service. How to define the health status of a service is a key point, because sometimes although the service It is online, but its service resources are indeed unavailable, which will also cause the service to be unavailable
