Problems solved by technology

[0002] When an abnormality occurs in a smart device such as a server, it often needs to be restarted to solve the abnormal problem. In a server with multiple servers, each server has multiple applications (components) installed. All the applications in the server are restarted, but the relationship between the applications is intricate and interdependent. It often happens that the application fails to start due to the wrong startup sequence. In addition, if the smart device installs a new application , the startup sequence of multiple applications needs to be readjusted, and the operation is complicated and error-prone

Abstract

The invention provides a server cluster and a startup method thereof. The server cluster startup method comprises the steps of starting at least one agent program in a server cluster when it is detected that an operation system of the server cluster is started, wherein the agent programs correspond to different components respectively, and the components are prohibited from being started with startup of the operation system; and based on a startup sequence of the components, sending instructions of starting the corresponding components to the agent programs respectively, thereby enabling the components to be started according to the startup sequence.

Description

technical field [0001] The invention relates to the field of software engineering, in particular to a server cluster and a starting method thereof. Background technique [0002] When an abnormality occurs in a smart device such as a server, it often needs to be restarted to solve the abnormal problem. In a server with multiple servers, each server has multiple applications (components) installed. All the applications in the server are restarted, but the relationship between the applications is intricate and interdependent. It often happens that the application fails to start due to the wrong startup sequence. In addition, if the smart device installs a new application , the startup sequence of multiple applications needs to be readjusted, and the operation is complicated and error-prone. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a method and device for starting multiple servers, the method can enable the appli...
