Abstract
It is a kind of that to refer in particular to the server based on active/standby modes based on HA double-machine standby technologies hot standby.Server data includes database data and write simultaneously toward two or multiple servers, or uses a shared storage device.There was only a server operation within the same time.When which to run a server break down can not start when, another backup server can be examined surveys (being diagnosed generally by heartbeat) by software and activate standby machines, it is ensured that application in a short time completely recovery normally use.
Description
Technical field
HA double-machine standby technologies are based on the present invention relates to one kind, belong to the balanced field of computer load.
Background technology
Increasingly focus on the construction of informationization in modern society's constituent parts and enterprise, information system turns into enterprise, cause list
Indispensable important component in the daily operation of position.Constantly expand and associate along with business, can all newly increase every year
Various application systems, information system is also more and more huger, becomes increasingly complex, and the possibility that risk is produced is consequently increased.
The risk that information system faces：
Logic error：Probability of happening is very high, artificial maloperation, virus, the factor such as staging error.
Server hardware failure：Probability of happening is higher, influence applied business interruption.
Storage media failure：Probability of happening is higher, storage and server hard disc, ageing equipment.
If can not be adopted an effective measure to risk, once data are lost due to certain above-mentioned reason, it is possible to cause
Extreme loss.When especially core data is lost, it is entirely possible to cause the paralysis of whole operation system.Only with conventional backup means
Protected, solution problem is limited, with the very big gap of actual demand.Existing backup inefficiency is mainly reflected in, is broken down
Afterwards, recover very long cumbersome, operability is very low, and business is for interrupt status in data recovery procedure, it is impossible to externally provide service.
Generally speaking, technical staff at the scene in the case of, recover server may normally need 10 minutes, a few houres
Even several days.From practical experience, only simply restart server (possible hidden danger still has), otherwise generally require
It is more than several hours.And if technical staff at the scene, then do not recover service time just it is longer.
And for some important systems, it is difficult to stand so prolonged service disruption that user, which is,.Therefore, just need
Will be by two-node cluster hot backup, to avoid prolonged service disruption, it is ensured that system is long-term, reliable service.Two-node cluster hot backup is for just
It is the hardware and software failure problem of server, including equipment fault, operating system failure, software systems failure etc..
The characteristics of two-node cluster hot backup：It is hot standby that the server based on active/standby modes is refered in particular in two-node cluster hot backup.Server
Data include database data and write simultaneously toward two or multiple servers, or use a shared storage device.Same
Only one server operation in time.When which to run a server break down can not start when, another is standby
Part server can be examined survey (being diagnosed generally by heartbeat) by software and activate standby machines, it is ensured that be applied in the short time
Interior complete recovery is normally used.
Two-node cluster hot backup implementation pattern has two kinds, and a kind of is the mode based on shared storage device, and another is uncommon
The mode for the storage device enjoyed, commonly referred to as pure software mode.It is the most mark of two-node cluster hot backup based on the shared two-node cluster hot backup of storage
Quasi-project.
For sharing storage mode, using two-server, shared storage device (magnetic disk array cabinet or memory block are used
Net SAN in domain).Two-server can be by the way of mutual standby, principal and subordinate, parallel etc. be different.In the course of the work, two-server
Service will be externally provided with a virtual IP address, according to the difference of working method, service request is sent to wherein one clothes
Business device undertakes.Meanwhile, server passes through heartbeat (often using by way of setting up private network) another server of detecting
Working condition.When a server breaks down, another server is judged according to the situation of heart beat detection, and is carried out
Switching, adapter service.For a user, this process is full automatic, is completed within a very short time, so that will not to business
Impact.Due to using shared storage device, therefore the actually the same data that two-server is used, by two-shipper
Or clustered software is managed to it.
Then it is the duplex software by supporting mirror image for the mode of pure software, data can be copied in real time another
On platform server, just respectively there is portion in so same data on two-server, can if a server breaks down
To be switched to another server in time.
Pure software mode also has another situation, i.e. server to be only to provide application service, and does not preserve data (ratio
As only carried out some calculating, used as application server).In this case equally set also without using shared storage
Standby, such case should include load balancing field.
The content of the invention
The invention aims to ensure when hardware and software failure occurs in operation system, the situation of manual intervention is not being needed
Under, it is automatic that the offer service that operation system can continue is provided.Operation system application is ensured using the method for two-node cluster hot backup.
In order to reach the purpose of operational sustainability, the technical proposal of the invention is realized in this way：
Server data includes database data and write simultaneously toward two or multiple servers, or shared is deposited using one
Store up equipment.There was only a server operation within the same time.When which to run a server break down can not open
When dynamic, another backup server can be examined survey (being diagnosed generally by heartbeat) by software and activate standby machines, it is ensured that
Using recovery is normally used completely in a short time.Such as Fig. 1
Its method and step is as follows：
First：Server data includes database data and write simultaneously toward two or multiple servers, or using one altogether
The storage device enjoyed.
Secondly：When business main frame breaks down, survey program activation standby host is examined by software.
Finally：Standby host adapter business, it is ensured that application recovers normally to use in a short time completely.
Brief description of the drawings
Fig. 1, one kind are based on HA double-machine standby technologies
Embodiment
In order that the purpose of the present invention, technical scheme and feasibility are more clearly understood, with reference to accompanying drawing, to present invention progress
It is further to describe in detail.It should be appreciated that specific embodiment described herein is only to explain the present invention, and without
It is of the invention in limiting.
The present invention proposes a kind of method based on two-node cluster hot backup, it is ensured that operation system safety and reliability.
Methods described comprises the steps：
First：Two-shipper environment is built, server data includes database data and write simultaneously toward two or multiple servers, or
Person uses a shared storage device.
Secondly：When business main frame breaks down, survey program activation standby host is examined by software.
Finally：Standby host adapter business, it is ensured that application recovers normally to use in a short time completely.
Claims (3)
