Abstract

The invention discloses a rolling upgrading method, device and equipment and a computer readable medium, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: in a preset failover service node queue, determining a next service node of a current node according to the current service node, and when the current service node fails, forwarding a client request received by a gateway to the next service node; starting from the first service node in the preset failover service node queue, selecting non-adjacent service nodes to generate a rolling upgrading service node queue; and upgrading the service nodes, wherein the upgraded service nodes comprise service nodes except the current service node and the next service node in the rolling upgrading service node queue. According to the embodiment, the one-time success rate of client access during rolling upgrading can be improved, and access delay and access failure are reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a rolling upgrade method, device, equipment and computer readable medium. Background technique [0002] Rolling upgrade is a common strategy in cluster upgrade, because it does not consume additional resources, supports grayscale verification and timely rollback under the cost of iteration, and is widely used in cluster upgrade. The essence of rolling upgrade is that the continuity of service can be maintained during the upgrade process, so that the outside world is not aware of the upgrade process. [0003] In the process of implementing the present invention, the inventors have found at least the following problems in the prior art: the one-time success rate of client access is low during rolling upgrade, and access delays and access failures often occur. Contents of the invention [0004] In view of this, embodiments of the present invention provide a rolling upgr...
