Description
Technical field
The present invention relates to computer communication network technical field, particularly relate to a kind of implementation method of virtual IP address.
Background technology
In computer cluster system, realize the High Availabitity service of business mainly by increasing node, under making multiple node be operated in load sharing mode or under main-standby mode, when primary node failure, back-up paths is taken over primary node and is continued to provide service.Because digital communications network is to the differentiation of complete IP network, make the mainly IP-based communication of the communication mode of node.When primary node failure, the client of accessing primary node can continue to ask for service to the IP address of primary node, with same IP address provision service when this will ask back-up paths to take over primary node, so multiple node being shared an IP address will externally provide the method for service to be called virtual IP address (VIP).
Mostly the implementation method of existing virtual IP address, for the computer cluster of multiple servers composition, be to be realized by configuration virtual IP manually, such implementation labor intensive cost; Existing virtual IP address implementation method is change by increasing the IP address of network address translation (NAT) equipment to multiple server in addition, multiple server is made externally to present a unified IP address, the NAT device that such implementation needs increase by special, adds networking and maintenance cost.There is no a kind of more practicable method being realized the functions such as virtual IP address increase, deletion by server self at present.
Summary of the invention
For solving problems of the prior art, the present invention proposes a kind of implementation method of virtual IP address, the functions such as virtual IP address increase, deletion are realized by server self, a database purchase virtual IP address is shared between server, server self realizes increase and the deletion of virtual IP address, does not need to control by the configuration of other hardware storage device to server virtual IP.
