Method and device for configuring server cluster

Abstract

The embodiment of the invention provides a method and a device for configuring a server cluster. The method comprises the following steps: running a dynamic routing protocol on a plurality of virtual servers in a virtual server cluster and a router connected with the plurality of virtual servers; sending link information of corresponding virtual IP (internet protocol) from the plurality of virtual servers to the router; generating a corresponding multi-path router for the plurality of virtual servers on the router according to the link information of the corresponding virtual IP; and distributing the traffic flows corresponding to the virtual IP from the router to the corresponding virtual servers through the multi-path router. According to the invention, the problem of performance bottleneck of the single virtual server can be solved, the virtual server cluster can be extended simply and conveniently, and the operation and maintenance cost is greatly reduced.

Description

technical field [0001] The present invention relates to a virtual server, in particular to a method and device for configuring a virtual server cluster (cluster). Background technique [0002] As a network access device, a virtual server is responsible for load balancing of traffic and must have high availability and high performance. Currently, high availability is implemented through the VRRP (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol) heartbeat protocol. The VRRP heartbeat protocol is designed to solve the single point of failure problem caused by static routing. The core of VRRP is a selection protocol, which can dynamically assign the responsibility of a virtual router to one of the VRRP routers on the LAN. The VRRP router that controls the IP addresses of the virtual routers is called the master router, and it is responsible for forwarding packets to these virtual IP addresses. This election process provides a dynamic failover mechanism ...

Problems solved by technology

[0007] (1) A single virtual server becomes a performance bottleneck: because the traffic of a specific virtual IP can only be forwarded to one virtual server within a certain period of time, if the traffic corresponding to the virtual IP is large, the virtual server will become a performance bottleneck;

[0008] (2) The expansion of the virtual server cluster is more complicated: under normal circumstances, two virtual servers are used to form a cluster to provide services, but as the number of businesses and traffic increase, the performance of the cluster will encounter bottlenecks. At this time, it is necessary to expand the virtual server There are two ways to expand server clusters: (a) Create a new cluster of two virtual servers. The problem is that it is necessary to artificially divide services among multiple clusters for traffic balancing. If a certain business traffic becomes larger , and needs to be adjusted at any time, (b) adding virtual servers to the original cluster, the problem is that it is necessary to artificially divide the priority of each virtual server for each business, in order to achieve the traffic balance of each virtual server and the high performance of each business Availability, taking a cluster of three virtual servers (assumed to be virtual server A, virtual server B, and virtual server C) as an example, assuming that the cluster undertakes three services (business 1, business 2, and business 3)

But if another virtual server D is added, then the priority setting of each business on the virtual server D will be very complicated and cumbersome
