Problems solved by technology

[0003] When the prior art realizes the virtual Internet Protocol (Virtual IP, VIP) address, the network card description information corresponding to the actual IP, the virtual IP and its subnet mask, the virtual IP setting state and the role information of each service node (master or standby machine) ), are stored in the database, which makes this solution highly dependent on the database and cannot be used alone, and once the database is abnormal and cannot be accessed normally, this virtual IP cannot be switched between the main and standby machines

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] The embodiment of this application provides a method for implementing VIP address drift in an HA system, which is applied to the windows platform. In actual implementation, if the service node serving as the master node fails, the master and backup nodes will automatically implement online VIP address switching, thereby realizing The VIP address drifts between the active and standby nodes. On the basis of high availability and high reliability, it can ensure that the external services of the system will not be interrupted when a single node is abnormal (the client accesses the HA cluster through the VIP address, and the service node provides HA services for the client) .

Abstract

The invention provides a method for realizing VIP address drift in an HA system, which is applied to any service node in the HA system, and comprises the following steps: when the service node is usedas a main node, if it is determined that the service node has a fault, unloading a VIP address, and switching the service node to a standby node; when the service node serves as a standby node, if itis determined that the main node breaks down, the service node does not break down and the VIP address is not occupied, the VIP address is mounted locally, the service node is switched to be the mainnode, and the VIP address is used for providing application service for the outside. According to the scheme, on the basis of high availability and high reliability, the external service of the system is not interrupted when a single node is abnormal.

Description

technical field [0001] The invention relates to the technical field of cluster applications, in particular to a method and device for realizing VIP address drift in an HA system. Background technique [0002] In the field of high availability cluster (High Available, HA) cluster application technology, HA clusters are mainly used in scenarios that require high system availability, requiring uninterruptible services and 7×24 online. [0003] When the prior art realizes the virtual Internet Protocol (Virtual IP, VIP) address, the network card description information corresponding to the actual IP, the virtual IP and its subnet mask, the virtual IP setting state and the role information of each service node (master or standby machine) ), are stored in the database, which makes this solution highly dependent on the database and cannot be used alone, and once the database is abnormal and cannot be accessed normally, this virtual IP cannot be switched between the main and standby ...
