Description
Technical field
What the present invention relates to is redundancy technique field, is specifically related to a kind of dual-machine hot backup system.
Background technology
Dual-machine hot backup system belongs to the one of cluster, and cluster refers to that one group of separate server shows as single system in network, and is managed with single pattern.This triangular web provides service and the Internet resources of high availability as a whole.In cluster, all computers have a common title, and the service moving in arbitrary system in cluster can be used by all network clients.Cluster must be able to be coordinated and managed the wrong and failure of the node of each separation, and these faults are by user awareness, and can add pellucidly assembly to expand its service ability.
Two-node cluster hot backup technology is a kind of higher error-tolerant applications scheme of software and hardware combining.This scheme is by two-server system and an external shared disk disk array cabinet (also can not have, but take RAID card in server separately) and corresponding two-node cluster hot backup software composition.
In this fault-tolerant networks, operating system and application program are arranged on the local system dish of two-server, and the data of whole network system are managed concentratedly and data backup by disk array.Data centralization management is by dual-machine hot backup system, the data of all websites is directly read and is stored from central storage device, and managed by professional, has greatly protected fail safe and the confidentiality of data.User's deposit data is in external shared disk array, and in the time that a station server breaks down, standby host initiatively substitutes host work, guarantees that network service is uninterrupted.
Dual-machine hot backup system adopts " heartbeat " method to guarantee contacting of main system and back-up system.So-called " heartbeat ", refers between master-slave system and mutually sends communication signal according to certain time interval, shows the current running status of system separately.Once " heartbeat " signal stops showing that host computer system breaks down, or back-up system cannot be received host computer system " heartbeat " signal, the high availability management software of system thinks that host computer system breaks down, main frame quits work, and system resource is transferred in back-up system, back-up system will substitute main frame and play a role, uninterrupted to guarantee network service operation.
In two-node cluster hot backup scheme, can there be three kinds of different mode of operations according to the working method of two-server, that is: two-node cluster hot backup pattern, the mutually standby pattern of two-shipper and two-shipper dual-mode.The current usually said active/standby mode of two-node cluster hot backup pattern, active server is in running order; And standby server is in monitoring standby condition, server data comprises that database data simultaneously writes (common each server adopts RAID magnetic disc array card) toward two or multiple servers, guarantees the instant synchronous of data.In the time that active server breaks down, examine and survey or manual mode activates standby machine by software, guarantee that application recovers normal use at short notice completely.Typical case is applied in security fund server or quotation service device.This is the more a kind of pattern that adopts at present, but due to the other station server state in standby for a long time, considers from computational resource aspect, just has certain waste; The mutually standby pattern of two-shipper, that two relatively independent two machines that are applied in move simultaneously, but be all made as each other standby host, in the time that a certain station server breaks down, another station server can be taken over the application of failed server to come at short notice, thereby guaranteed the continuation of application, but higher to the performance requirement of server.Configuration will be got well relatively; Two-shipper dual-mode: be that current cluster(troops) a kind of form, two-server is activity, moves identical application simultaneously, guarantees overall performance, also realized load balancing and backuped each other, need to utilize disk chassis memory technology (preferably adopting San mode).WEB server or ftp server etc. are many by this kind of mode.
Concerning modern enterprise, utilize computer system to provide in time information and service to be reliably absolutely necessary, on the other hand, computer hardware and software all inevitably can break down, these faults are likely brought great loss to enterprise, the termination of even whole service, the paralysis of network.It is important that the fault-tolerance of system and continuity especially seem.The security reliability of current dual-machine hot backup system is on the market not high, uses very inconvenient.
