Abstract

The invention provides a virtual IP balanced distribution method and system, a terminal and a storage medium. The method comprises the steps of: obtaining virtual IP holding information of available nodes of a cluster; according to the holding information, screening out available nodes with the least holding service IPs to serve as target nodes; and distributing the virtual IP of a fault node to the target nodes. The virtual IP balanced distribution algorithm under a service IP non-drifting condition is provided. According to the virtual IP redistribution algorithm, the IP redistribution algorithm of a specific scene is developed for specific requirements of customers, the defect that few IP redistribution trial scenes exist in an AS13000 product at present is overcome, and the high availability of an AS13000 system is improved.

Description

technical field [0001] The invention relates to the technical field of cluster virtual IP, in particular to a virtual IP balanced distribution method, system, terminal and storage medium. Background technique [0002] High Availability HA (High Availability) refers to improving the availability of systems and applications by minimizing the downtime caused by routine maintenance operations (planned) and sudden system crashes (unplanned). The HA system is currently the most effective means for enterprises to prevent the core computer system from shutting down due to failure. The ctdb module is currently used as a simple HA component in server san and object storage modules, including AS 18000 products, which have listed ctdb in the high availability solution. The cluster functions provided by Ctdb, such as virtual IP drift, node monitoring and management, and module supervision, can already meet various high-availability project scenarios. When there is a downtime or a monit...
