Description
Technical field
The present invention relates to a kind of computer backup comprehensive control management system, belong to the fault-tolerant field of Backup service.
Background technology
At present, backup fault-tolerant networks reliability and stability being required to higher system adopts such scheme mostly, i.e. main frame one standby host of configuration, and require that both install identical service routine, switching condition between the two is to be detected by specific message, if judging, main frame breaks down, then standby host switches to main frame, to provide lasting service.There is such problem in many applications in such back mechanism:
(1) cost is high.One main frame needs one standby host of configuration, is original twice on hardware cost.It addition, for machine room, a machine just needs a riding position, also has very big pressure for machine room space.For safeguarding, a machine also implies that many a maintenance workloads.
(2) protection of backup services is limited.One main frame can only be backed-up by one standby host, if machine breaks down after backup, then cannot be carried out backup.
(3) can only same application Backup service.Main frame and standby host are symmetrical, and standby host requires to install the application identical with main frame, carries out active and standby setting when starting.
(4) switching condition is to be detected by specific message.It is exclusive that these message are usually these application systems oneself, does not have versatility.
(5) scheduling mechanism is complicated and need independent controlling equipment.When multiple devices arrange multiple stage standby host, being generally adopted independent controlling equipment and include the scheduling mechanism of complexity, so independent controlling equipment itself breaks down, and whole back mechanism can be caused to lose efficacy, and add cost.
Summary of the invention
The purpose of the present invention, to efficiently solve the problems referred to above, it is provided that a kind of M effect heavily backed up that can reach, and as required can one backup multiple stage, back mechanism is flexible, and the configuration in economy and reliability has the computer backup comprehensive control management system of good scalability.
The general thought that realizes of the present invention is: one or some standby servers (being called standby host) realize the monitoring to some primary server services (being called main frame) and backup, and the main method adopting the switching of IP address realizes.All hosts is intercepted by standby host, checks whether main frame is in network, if checking in main frame certain time not in a network, then think that this main frame breaks down, now the IP of standby host is changed into the IP of failed host, and starts corresponding service, replace it to provide service.After failed host repairs re-accessing network, the standby host of replacement stops current service, is changeed back by IP as original IP, original host continuation offer service.
Multiple host is monitored and multiple duplication to realize multiple stage standby host, adopt to dispatch and with testing mechanism be: first every standby host is numbered, every standby host only detects numbering standby host before it, if this standby host is numbering foremost (also referred to as number one standby host), then need All hosts is detected.As long as the principle of detection is the standby host finding numbering before it, just stops detection, write down the information of this machine, follow-up this standby host of preferential detection.If can not find numbering standby host (number one standby host) before it, then detect All hosts.If what switched to main frame is numbered i(i < N) machine switch back into standby host, then the standby host numbered before it is detected by this standby host, if this standby host is the standby host coming foremost, if and numbering exists the standby host (being namely numbered, before switching, the standby host coming foremost) that all N platform main frames are detected from i+1 to M, then changing the detection machine of this machine (being numbered the machine between i+1 to N) into be numbered i standby host.
After recovering for main frame, the thinking solving IP conflict is: configuring two IP addresses on a main frame, two addresses can use in a network.When switching back-up machine takies one IP address, main frame can be pointed out IP to conflict, but another one IP address still can access network, thus can be communicated by this IP, make active/standby server return to original state after being recovered.Two IP addresses for main frame: one is called service IP, mainly externally provides service with this IP, and another one is called tracks down IP, is mainly used to offer and standby host is communicated use.
Accompanying drawing explanation
Fig. 1 is host services schematic flow sheet；
Fig. 2 is standby host service procedure schematic diagram.
Detailed description of the invention
As depicted in figs. 1 and 2, having N platform main frame and M platform standby host, main frame is numbered A1, A2 ..., AN, standby host is numbered B1, B2 ..., BM.B1 comes foremost, is number minimum in the standby host existed, and for number one standby host, it is responsible for checking All hosts, and it is just passable that standby host B2 has only to detect that B1 exists, and other standby hosts only need to detect the presence of that to number little standby host than oneself just passable.If there being main frame to break down, then standby host B1 carries out IP switching, and starts respective service, replacing host work, standby host B2 then becomes the standby host that numbering is minimum, i.e. number one standby host, being responsible for detection All hosts, other standby hosts have only to detect the presence of the standby host less than oneself numbering.
Although functionally there are differences at main frame and standby host, but being designed as a set of program, being identified the identity of this machine by configuration file, it is determined that the service of its offer.
Configuration instruction: machine type includes main frame and standby host two, it is necessary to configures in configuration file, is identified its identity with ID between identical machine type.Must configuring 2 IP in main frame, one is service IP, and another one is for tracking down IP.The IP address that service IP adopts when being to provide service, tracks down IP for intercepting the message that other servers send over.
The function that host computer side provides:
1) local process is managed, startup and the closedown to host services, when service being hung extremely or extremely exits, restarts process.
2) by tracking down IP, the message that other servers send over is intercepted.If receiving the order (switching command) restarting network service, then reset service IP, then restart corresponding service.
The function that standby host side provides:
1) management local process, starts as required and closes corresponding service routine.
2) whether in a network other standby hosts are detected.(needing to specify the standby host list intercepted)
3) whether detecting server is in network, and in detecting server, whether certain service provides service.(needing to specify the list intercepting server)
4) carry out the switching of IP address, and start respective service as required.
5) IP address is switched back into original standby host, and close service.Notify recovered normal server amendment IP address (transmission switching command).
Invention described above embodiment, is not intended that limiting the scope of the present invention.Any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within the claims of the present invention.
