Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a physical machine service upgrade method, system, device and computer-readable medium. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the application that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.

[0003] In the process of upgrading the traditional service architecture, the gradual iterative upgrade of services is generally achieved through the following two methods: one method is to directly use new services to replace old services; the other method is to directly deploy new services and distribute part of the traffic to the new services through the load balancer.

[0004] However, the above method has the following problems: on the one hand, although the service upgrade and rollback can be achieved by configuring the retry strategy, functional requirements such as dual writing / dual reading of new / old services cannot be achieved; on the other hand, without modifying the service architecture program, the consistency of the response information returned by the new / old service cannot be verified; on the other hand, when a load balancer is used to implement the upgrade, the configuration of the load balancer needs to be updated every time the service is upgraded and rolled back, which increases the risk and complexity of the service architecture; on the other hand, in specific business scenarios, the business program needs to be modified to implement the service upgrade.

[0005] Therefore, there is an urgent need to propose a physical machine service upgrade method, system, device and computer-readable medium that can solve the above problems. Summary of the invention

[0044] Embodiment 1

[0045] This embodiment provides a physical machine service upgrade method, which is applied to a physical machine service upgrade system including iptables and a proxy process to upgrade an old service to a new service. The method includes:

[0046] In response to a service upgrade request, obtain the old service port, start the new service, and set the new service port;

[0047] Start the proxy process to forward the request information sent by the upper-level user to the old service port to the new service port;

[0048] Configure iptables to forward the request information sent by the upper-layer user to the old service port to the proxy process, and the proxy process sends the request information forwarded by iptables to the old service and / or the new service.

[0049] Specifically, the proxy process serves as the decision-making mechanism for new and old services, and its main operations include: traffic direction decision, data comparison decision, new and old service switching node decision, etc. That is, when a new service is just launched, the accuracy of the service cannot be guaranteed. At this time, the decision in the proxy process is based on the read and write results of the old service, and the new service is only observed in the bypass; but after the basic function of the new service is successfully verified, the proxy process decision can be set to compare whether the data returned by the new service is consistent with the data returned by the old service. After confirming that the consistency verification is sufficient, the new service read and write results can be set as the benchmark, and the old service can be used for fault rollback. In this way, the proxy process can control the role positioning of new and old services.

[0050] In one of the implementation modes, the method further includes: within a preset first time period, the proxy process sets the old service as the main service, so that the old service returns the response information to the upper-level user.

[0051] In one of the embodiments, the method further includes: within a preset second time period, the proxy process sets the new service as the primary service and the old service as the secondary service, so that the new service returns response information to the upper-level user.

[0052] In one embodiment, the method further includes: within a preset second time period, and / or within a preset first time period, the proxy service obtains the response information returned by the new service and the old service for verification. Within the preset second time period, when the response information returned by the new service is inconsistent with the response information returned by the old service, the old service is switched back to the main service, and the business code of the new service is re-modified and launched, so as to achieve client-unawareness and program hot repair.

[0053] In one of the embodiments, within a preset third time period, after confirming that the response information returned by the new service is correct, iptables will be deleted, the proxy process will be terminated and the old service will be decoupled. The proxy process will switch the new service as the main service so that it returns response information to the upper-level user to achieve a physical machine service upgrade.

By configuring iptables and the proxy process, data verification and data selection can be freely implemented without making business changes.

[0063] In one embodiment, the proxy process switches the new service as the main service so that it returns a response message to the upper-level user, and also includes: if the consistency frequency exceeds a second preset value, deleting iptables, terminating the proxy process and decoupling the old service, and the proxy process switches the new service as the main service so that it returns a response message to the upper-level user to achieve a physical machine service upgrade.

[0064] In order to ensure the accuracy of the response information returned by the new service while reducing the occupancy rate of the system storage space. In one embodiment, the preset new and old service switching rules also include: if the consistency frequency of the response information returned by the old service and the new service exceeds the first preset value and does not exceed the second preset value, the proxy process verifies the consistency of the response information returned by the old service and the new service; if the proxy process verifies that the response information returned by the old service and the new service is consistent, the proxy process discards the response information returned by the old service.

[0065] Based on the physical machine service upgrade method described in this embodiment, by configuring iptables and proxy processes, the upstream and downstream are decoupled without the need for business changes, so as to achieve free and smooth switching of new and old services without upstream and downstream perception, ultimately achieving the purpose of service upgrade.
