Description
Technical field
The present invention relates to technical field of the computer network, more particularly to a kind of method of cluster server caching load balancing
And system.
Background technology
Server disposition, refers to dynamically set server cluster according to the actual demand of enterprise or user, right
The equipment of server carries out software or the corresponding of hardware sets, operates, the capacity and processing energy of dynamic regulation server cluster
Power, so as to meet the needs of enterprise or user, realizes the purpose of business activity.
With the continuous development become increasingly popular with network application of network broadband, customer service demand and to server process
The demand of ability is in Fast growth phase, constantly challenges to server technology development.In order to solve business demand kimonos
Imbalance between device disposal ability of being engaged in, server technology is from the one-to-many framework of one-node network server, to cluster
Change, the migration of the multi-to-multi framework of multiserver, extend the disposal ability and bandwidth of server, it is cheap, efficient, reliable to realize
Network service capabilities.Application server cluster can obtain very high calculating speed from the parallel computation of multiple computers,
It can also be backuped with multiple computers, so that whole system still can be transported normally after any one machine disruptions service
OK, the efficiency and stability of server handling ability be ensure that.
Server cluster is organically to connect the server of one group of independence by certain mechanism (network connection), group
Into the multi-server system of a loose coupling, be deployed in application program in these servers can by network share memory,
Messaging is carried out, interprocess communication is realized, so as to fulfill Distributed Calculation.Externally, server cluster is only one
A system, externally provides unified service.
Server cluster pattern mainly has redundant mode and load-sharing mode.Redundant mode is also known as active/standby pattern, is one
The asymmetric cluster topology of kind, has some servers dedicated for taking over their work when workspace server breaks down.It is negative
It is a kind of symmetrical cluster topology to carry balanced mode, and each server has been borne by work, and all mutual equality of every server, does not have
Dedicated for spare server.If server breaks down, remaining server, which may proceed to handle its own, to be divided
The application load matched somebody with somebody, while the application load on the server to break down is handled, specifically connect by any platform or which platform server
Pipe, will see that cluster service is configured with.
Server cluster load-balancing technique more commonly used at present mainly has：
1), the load balancing based on DNS.Load balancing is realized by the random name resolution in DNS service, in DNS
Can be multiple and different same names of address configuration in server, and the client computer for finally inquiring about this name will solve
One of address is obtained when analysing this name.Therefore, different ground can be obtained for same name, different client computer
Location, they also just access the Web server in different address, so as to achieve the purpose that load balancing.
2), reverse proxy load balancing (such as Apache+JK+Tomcat combinations).It will can be asked using proxy server
The Web server of inside is transmitted to, allows proxy server to ask equably to be transmitted to more internal web clothes according to certain algorithm
It is engaged on one of device, so as to achieve the purpose that load balancing.This agent way and common agent way are different, standard generation
Reason mode is that client uses the multiple external web servers of proxy access, and this agent way is multiple clients' use agency's visits
Ask multiple internal Web services devices, therefore also referred to as reverse proxy pattern.
3) load-balancing technique (such as Linux Virtual, based on NAT (Network Address Translation)
Server, abbreviation LVS).NAT (network address translation) refers to inwardly to be changed between location and external address, to possess
The computer capacity of home address accesses external network, and works as certain that the computer access address transfer gateway in external network possesses
During one external address, address conversion gateway can be transferred it in the home address of a mapping.So if address conversion net
Close can by it is each connection uniformly be converted to different internal server addresses, hereafter the computer in external network just each with from
Server communicates on the address that oneself is converted to, so as to achieve the purpose that load balancing.
But for the memory management of cluster server, there has been no ripe administrative skill.Streaming media on demand, P2P should
Network traffics and server processing business can be caused with the popular the Internet, applications such as, large-scale 3D online games, shopping at network
Short high peak and imbalance, need substantial amounts of memory of quoting quickly to handle data, can form industry particularly across the business of platform
The wave crest and trough of business, the disposal ability of server cluster are greatly tested, and equipment has delay machine or the wind of loss of data
Danger, causes bad experience to user, also result in the loss of economic interests.
The content of the invention
The present invention provides a kind of method of cluster server caching load balancing, is formed between server cluster caching negative
Equilibrium is carried, strengthens the caching process ability of server cluster, improves the O＆M stability of server cluster, saved server and set
