Data synchronization method and device, equipment and medium

Abstract

The invention discloses a data synchronization method and device, equipment and a medium. The method comprises the steps that node information, sent by a database management platform, of a standby node corresponding to a main node is acquired; SSH connection with the standby node is established by using the node information; a second port of a database on the main node is monitored through a first port of an SSH client on the main node, and the first port and the second port only expose the main node; if the first port monitors the to-be-synchronized data output by the second port, the to-be-synchronized data is sent to the standby node through the SSH connection, so that when an SSH server side on the standby node receives the to-be-synchronized data, the to-be-synchronized data is stored in a database through a third port of the database on the standby node, and the third port only exposes the standby node. Therefore, a high-security data synchronization method for the main and standby nodes can be provided on a database management platform based on cloud computing, and the security of the whole database management platform is improved.

Description

technical field [0001] The present application relates to the technical field of cloud computing, and in particular to a data synchronization method, device, equipment, and medium. Background technique [0002] When a cloud computing-based database management platform performs master-slave data synchronization, the data transmitted in plain text is easily obtained by an intermediary, resulting in information leakage and losses. In addition, when the master-slave data is synchronized, the database service ports on the master node and the standby node need to For public network exposure, the ports directly exposed in the public network are vulnerable to hackers, which further increases the possibility of data leakage during the master-slave data synchronization process, resulting in a decrease in the security performance of the entire cloud-based database management platform. [0003] Therefore, how to provide a highly secure data synchronization method on a cloud computing-ba...
