Abstract
The present invention relates to a comprehensive control and management system for computer backups, including a multiple backup mechanism that M backup computers can replace N hosts to provide service in a manner of IP switchover. The comprehensive control and management system for computer backups has the advantages of a good expansibility due to a simple and flexible deployment; a high stability due to multiple backup supporting; a good applicability due to the fact that various services of N servers are supported; a good usability due to simple multiple backup scheduling; and a low network overhead due to less mutual detection amount of the servers.
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, reliability and stability are required that the backup fault-tolerant networks of higher system adopts such scheme mostly, i.e. host configuration standby host, and both requiring, identical service routine is installed, switching condition is between the two detected by specific message, if judge, 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.A main frame needs configuration standby host, hardware cost is original twice.In addition, for machine room, a machine just needs a riding position, also has very large pressure for machine room space.For maintenance, a machine also just means how a maintenance workload.
(2) protection of backup services is limited.A standby host can only back up a main frame, if machine breaks down after backup, then cannot carry out having backed up.
(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 detected by specific message.These message are generally that these application systems oneself are exclusive, do not have versatility.
(5) scheduling mechanism is complicated and need independent controlling equipment.When arranging multiple stage standby host to multiple devices, generally adopt independent controlling equipment and include complicated scheduling mechanism, controlling equipment independent like this itself breaks down, and whole back mechanism can be caused to lose efficacy, and add cost.
Summary of the invention
Object of the present invention, to effectively solve the problem, a kind of effect that can reach M and heavily back up is provided, and as required can one backup multiple stage, back mechanism is flexible, 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 monitoring to some primary server services (being called main frame) and backup, and the main method of IP address switchover that adopts realizes.Standby host is intercepted All hosts, checks whether main frame is in network, if to be checked through in main frame certain hour 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 start corresponding service, replace it to provide service.After failed host repairs re-accessing network, the standby host substituted stops current service, and changeed back by IP as original IP, original host continues to provide service.
In order to realize multiple stage standby host, multiple host is monitored and multiple duplication, employing scheduling and testing mechanism are: be first numbered every platform standby host, every platform standby host only detects the standby host of numbering before it, if this standby host is numbering foremost (also referred to as number one standby host), then need to detect All hosts.As long as the principle detected finds the standby host of numbering before it, just stop detecting, write down the information of this machine, follow-up this standby host of preferential detection.If can not find the standby host (number one standby host) of numbering before it, then detect All hosts.If what switched to main frame is numbered i(i<N) machine switch back standby host, then this standby host detects the standby host of numbering before it, if this standby host is the standby host coming foremost, if and there is the standby host (being numbered the standby host coming foremost before namely switching) detected all N platform main frames in numbering, then changes the detection machine of this machine (being numbered the machine between i+1 to N) into be numbered i standby host from i+1 to M.
After recovering for main frame, the thinking solving IP conflict is: on a main frame, configure two IP addresses, two addresses can use in a network.When switching back-up machine takies an one IP address, after main frame recovery, IP can be pointed out to conflict, but another one IP address still can accesses network, so just communicates by this IP, makes active/standby server return to original state.Two IP addresses for main frame: one is called service IP, mainly externally provides service with this IP, another one is called tracks down IP, is mainly used to provide carry out communication use to standby host.
Accompanying drawing explanation
Fig. 1 is host services schematic flow sheet;
Fig. 2 is standby host service procedure schematic diagram.
Embodiment
As depicted in figs. 1 and 2, have 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 to number minimum in the standby host existed, and is number one standby host, and it is responsible for checking All hosts, and it is just passable that standby host B2 only needs to detect that B1 exists, other standby hosts only need detect have just more passable than oneself numbering little standby host.If there is main frame to break down, then standby host B1 carries out IP switching, and starts respective service, replace host work, standby host B2 then becomes the minimum standby host of numbering, i.e. number one standby host, be responsible for detecting All hosts, other standby hosts only need to detect and also exist than oneself numbering little standby host.
Although functionally there are differences at main frame and standby host, be all designed to a set of program, identified the identity of this machine by configuration file, its service provided is provided.
Configuration instruction: Machine Type includes main frame and standby host two, needs to be configured in configuration file, carries out identifying its identity between identical Machine Type with ID.Must configure 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 and is used for intercepting the message that other servers send over.
The function that host computer side provides:
1) local process is managed, to startup and the closedown of host services, when service being hung extremely or extremely exits, restart process.
2) by tracking down IP, the message that other servers send over is intercepted.If receive the order (switching command) restarting network service, then reset service IP, then restart corresponding service.
The function that standby host side provides:
1) manage local process, start as required and close corresponding service routine.
2) whether in a network other standby hosts are detected.(needing to specify the standby host list intercepted)
3) whether detect server to be in network, in detecting server, whether certain service provides service.(needing to specify the list intercepting server)
4) carry out IP address switchover, and start respective service as required.
5) IP address switchover is returned original standby host, and close service.Notice has recovered normal server amendment IP address (transmission switching command).
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within claims of the present invention.
