Problems solved by technology

Due to the cumbersome DRBD mechanism, it is not easy to recover after a fault occurs. During the master-standby switchover process, the data copy of the DRBD node is required, which affects the time of the master-standby switchover.

Embodiment Construction

[0044] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0045] An embodiment of the present invention provides a data synchronization method for a dual-system hot backup environment, which is applied to a dual-system hot backup environment, where the dual-system hot backup environment includes: a primary cloud platform running on a master node and a The standby cloud platform on the node, such as figure 1 shown, including:

[0046]S1. When the primary cloud platform generates configuration data, the primary cloud platform stores the configuration data in a first local database and backs it up to the backup cloud platform, and the backup cloud platform receives the configuration data Then store it in the second local database;

Abstract

The present invention provides a data synchronization method and device for a dual-machine hot standby environment. The method includes: when the main cloud platform generates configuration data, the main cloud platform stores the configuration data in a first local database and backs it up to the backup The cloud platform, the standby cloud platform stores the configuration data in the second local database after receiving the configuration data; if the standby node does not exist, the main cloud platform stores the configuration data in the first local database and stores it in the cache module; When the standby node is newly added to the dual-system hot standby environment, the primary cloud platform acquires the configuration data in the cache module and backs it up in batches to the standby cloud platform, and the standby cloud platform stores it in the second local database after receiving it. The data synchronization method and device used in the dual-machine hot standby environment of the present invention do not need to perform data synchronization when the main cloud platform is restarted, or when the two platforms are switched between the active and standby, which reduces the time for switching between the active and standby, and reduces the time required for data synchronization. The complexity improves the stability of the cloud platform system.

Description

technical field [0001] The invention relates to the technical field of data synchronization, in particular to a data synchronization method and device for a dual-machine hot backup environment. Background technique [0002] With the development of cloud computing technology, the scale of the cloud platform has become larger and larger, ensuring the reliability of the cloud platform has become more and more important, and users have higher and higher requirements for the reliability of the cloud platform. HA (High Availability, high availability) is a technology to ensure the high availability of the system. The key to achieving high availability is to eliminate single points of failure and minimize downtime and service interruption time. Dual-system hot backup is a way to implement HA, that is, the cloud platform system is deployed on two server nodes at the same time. Normally, the cloud platform on one server node provides external services and is the master node; the othe...
