Technical Field
The present invention relates to the field of data synchronization technologies, and in particular, to a data synchronization method and apparatus for a dual-computer hot standby environment.
Background
With the development of cloud computing technology, the scale of a cloud platform becomes larger and larger, the reliability of the cloud platform is ensured to be more and more important, and the reliability requirement of a user on the cloud platform is higher and higher. HA (High Availability) is a technology that guarantees High Availability of the system, and the key to achieving High Availability is to eliminate single point failures and minimize down time and service interruption time. The dual-computer hot standby is a way to realize HA, that is, a cloud platform system is deployed on two server nodes at the same time, and normally, a cloud platform on one server node provides service to the outside and serves as a master node; the other node does not provide service for the idle state and is a standby node. When the cloud platform master node in normal operation is restarted or fails, the master node and the standby node are switched to another standby node in an idle state to continue providing services.
In the existing cloud platform system configuration mode, after the system deployment is completed in the dual-computer hot standby environment, one server node is selected as a master node and serves as a cloud platform for providing services to the outside. And the user logs in the main cloud platform to carry out configuration, and the configuration data is stored in the local database. When the main node fails or is restarted, the cloud platform of the standby node can manage the service and provide the service for the outside again. When the master node and the slave node are switched, the bottom layer of the cloud platform copies all data of the database of the master node to a database of another node in batch through a Distributed Replicated Block Device (DRBD) mechanism. Since the DRBD mechanism is complicated and is not easy to recover after a failure occurs, data copying of the DRBD node is required in the process of active/standby switching, which affects the time of active/standby switching.
