Upgrading method, equipment and distributed system of distributed application

Abstract

An embodiment of the invention provides a distributed application upgrade method, a device and a distributed system. The upgrade method comprises that a sub node acquires each piece of update content of an application running file on a main node; each piece of update content is generated when the main node updates the application running file on the main node according to an update file; the sub node controls in real time, according to each piece of update content acquired in real time, an application running file on the sub node to update synchronously with the application running file on the main node; and the sub node and the main node are nodes in a cluster, and an application running file on each node in the cluster corresponds to the same package of the same application. The invention can allow application versions on all the nodes to be consistent while updating the application, and can avoid the impact on the service or service quality provided by the application due to inconsistent application versions among the nodes.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a distributed application upgrade method, device and distributed system. Background technique [0002] The widespread application of cloud computing has changed the way people acquire, process and store information. The environment deployed by the cloud computing platform is often composed of hundreds or even thousands of servers. Specifically, the application (Application) used to provide cloud computing services is usually deployed on multiple nodes, that is to say, the application is distributed and deployed on larger nodes. When the application needs to be upgraded, the How to efficiently upgrade applications is an important issue. [0003] In the prior art, C / S (Client / Server, client / server) is usually used to upgrade distributed deployment applications, that is, to apply the latest version upgrade package or upgrade data on the server...

Problems solved by technology

However, when the number of applications, the number of components in the application, and the applications are deployed on many nodes, a large number of nodes will request the server to download upgrade data, which will increase the network bandwidth requirements of the server; when the network bandwidth of the server When the bandwidth cannot meet the download requirements of each node, it will cause some nodes to fail to download, so that the nodes that fail to download cannot be successfully upgraded, which further leads to inconsistent versions of the applications deployed on each node, affecting the cloud computing services or service quality provided by the applications
