Problems solved by technology

However, the ApsaraDB for RDS MySQL cluster has multiple nodes. When an exception occurs in the cluster and the public network IP is still bound to the original virtual machine (the old master node) after failover, the ApsaraDB for RDS MySQL cluster cannot be accessed normally.

Abstract

The invention particularly relates to a public network access restriction method and system for a public cloud MySQL cluster. According to the public network access limiting method and system for the public cloud MySQL cluster, an elastic public network IP is created on the public cloud, the elastic public network IP is bound to an elastic network card, and meanwhile the elastic network card is bound to a Master node virtual machine of the MySQL cluster; when the MySQL cluster breaks down and the Master node is abnormal, a MySQL cluster disaster recovery mechanism is triggered to conduct master-slave switching, meanwhile, the elastic network card is unbound from the old Master node, after master-slave switching, the elastic network card is bound to the new Master node, the elastic public network IP migrates along with the elastic network card, and it is ensured that the public network IP can always access the Master node. According to the public network access limitation method and system for the public cloud MySQL cluster, public network access and IP and IP segment access limitation of the MySQL cluster are realized based on the public cloud, meanwhile, the public network IP and the MySQL cluster are high in availability, services can be normally provided after disaster recovery switching occurs, and the availability of a cloud database RDS MySQL and the use safety of a user are enhanced.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method and system for restricting access to a public network of a public cloud MySQL cluster. Background technique [0002] The existing ApsaraDB for RDS MySQL can only be accessed by other resources in the same region and under the same private network through the intranet address, and resources outside the private network cannot be accessed. If the public network IP is bound to the ApsaraDB for RDS MySQL virtual machine (the master node Master), the requirements for accessing ApsaraDB for RDS MySQL from external network resources can be achieved. Using this method, external network resources can access the cloud database RDS MySQL. However, the ApsaraDB for RDS MySQL cluster has multiple nodes. When an exception occurs in the cluster and a failover occurs, the public IP is still bound to the original virtual machine (the old master node), and the ApsaraDB for RDS MyS...
