Process upgrading method, device and electronic equipment

Abstract

The application provides a method for upgrading a process, a device and electronic equipment; the method for upgrading a Redis process includes: after determining the upgrade, exit the asynchronous event loop of the dynamic library corresponding to the current version of the kernel; wherein, the dynamic library includes each of the Redis process Business logic; transfer the kernel environment data in the current Redis instance to the new version kernel; trigger the new version kernel to use the kernel environment data to initialize; enter the asynchronous event loop in the dynamic library corresponding to the new version kernel. At least one embodiment of the present application can implement hot upgrade of processes.

Description

technical field

[0001] The invention relates to the field of computers, in particular to a process upgrading method, device and electronic equipment. Background technique

[0002] Usually, users always expect the service to remain stable and never need to be restarted. But the function of the software is always enriched constantly. When users find that some new functions are needed, they will take the initiative to request an upgrade; when serious security problems arise, users will have to accept forced upgrades.

[0003] In the general upgrade process, the service always needs to be restarted. For users, there is a short-term service unavailable state. If the hot upgrade is implemented by deploying the old and new systems for switching, not only will there be overhead for an additional system, but also some service links will be disconnected or reset during the switching process.

[0004] Redis is an open-source, high-performance key-value pair (Key-Value) database, and...
