Embodiment Construction

[0048] With the development of society, it is often necessary to process a large amount of data in life. In some data processing services, if the data processing service is processed by a single device, and the data processing service requires many resources, the single device often has high requirements. However, the performance of a single device is limited, and when the business is run by a single device, the probability of operating failure is relatively high.

[0049] Based on this, a large amount of data processing work is often implemented by a cluster system. Wherein, the cluster system is a system composed of multiple servers connected to each other, and in the cluster system, the server is called a node (node). The cluster system improves the data processing capability by integrating the resources of each node.

[0050] When running services on the cluster system, the cluster system often has upgrades, such as the upgrade of software services on each node, or the u...

Abstract

An embodiment of the present application discloses an upgrading method for switching a current service of a first node to be upgraded to a second node so that the current service can run on the secondnode during the upgrading process of the first node. When the first node is upgraded, the current service can be switched back to the first node. As such, the current service can be continuously runin the upgrade process of the first node, and the user experience is improved. A method according to an embodiment of the present application comprises the follow steps: a first node obtains an upgrade instruction, wherein the upgrade instruction comprises an upgrade file; the first node switches the current service to a second node so that the current service runs on the second node. When the first node upgrades successfully according to the upgrade file, the first node switches the current service from the second node to the first node.

Description

technical field [0001] The present application relates to the field of cluster systems, in particular to an upgrading method and a server. Background technique [0002] A distributed storage cluster system generally includes multiple servers, which are connected to each other to form a cluster to provide external services in a unified manner. In a cluster system, the servers that make up the cluster can be represented by "nodes". [0003] The upgrade of the distributed storage cluster system includes the driver upgrade of hardware devices or the upgrade of some software services. When upgrading, each node in the cluster system needs to be upgraded one by one. The traditional distributed cluster upgrade method is mainly offline upgrade, that is, when a node is upgraded, the customer service on the node needs to be stopped, and the customer service is resumed after the node upgrade is completed. In order to reduce the impact as much as possible, offline upgrades are often pe...
