Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
It should be noted that in embodiments of the present invention, the concept of " a large amount of " refers to that 10,000,100,000 is even more more.Certainly, the embodiment of the present invention is equally applicable among the scene of prior art, so as to reach more preferable effect.
For the application request of a large amount of Web sites can be handled simultaneously, as shown in figure 1, the embodiment of the present invention realizes that the method for many Web application requests scheduling comprises the following steps：
Step 11, management control unit receive the domain name mapping sent by name server and asked（DNS request）.Wherein, in the DNS request, the domain name of user terminal requests can be carried, to facilitate the management control unit to carry out domain name mapping.In addition, the I P address information of source address is may also include in gangster S requests, to cause domain name server to determine to be sent to the user terminal of domain name analysis request.
Step 12, the management control unit are the good business device of domain name server-assignment at least one load balancing month according to domain name analysis request.
In systems in practice, the quantity of the load-balanced server may have 100 it is even more many.The information that the management control unit actively can be monitored or reported according to each load-balanced server in real time monitors the load data and operation conditions of each load-balanced server in real time, and then selection can be the load-balanced server of domain name server providing services.Wherein described load data can include the CPU utilization rates of each load-balanced server, memory usage, bandwidth utilization rate etc..
When selecting load-balanced server, the management control unit can be selected according to load-balancing algorithm.Such as described management control unit can be according to the loading condition of each load-balanced server in system, at least one minimum load-balanced server of selection load, and by the IP address of the load-balanced server
It is stored in load information in load-balanced server list, then sends the load-balanced server list to domain name server so that domain name server selects load-balanced server according to the load information of each load-balanced server.
Wherein, the load information may include the weight of the load-balanced server of selection, now, and domain name server directly can select load-balanced server according to the weight.Or the load information may include the loading condition of the load-balanced server of selection.When the load information includes the loading condition of the load-balanced server of selection, the weight of each load-balanced server is calculated according to the loading condition by domain name server, then load-balanced server is selected further according to the weight.Or the load information can also include the weight of load-balanced server and the loading condition that are selected by the management control unit simultaneously, now domain name server still can be directly according to weight selection load-balanced server.
In addition, after DNS request in order to avoid receiving user terminal every time, the information for the load-balanced server that can be supplied to service will be inquired about from domain name server to management control unit, domain name server can also preserve the load-balanced server list.
Also, when carrying the domain name of user terminal requests in domain name analysis request, the management control unit can also be parsed after domain name analysis request is received to the domain name that the user terminal is asked.Due to needing Slow to deposit the domain name of user terminal requests and the corresponding relation of Web server on load-balanced server, after the management control unit is parsed to the certain domain name A of user terminal requests, when having user terminal requests identical domain name again, because Slow deposited the corresponding relation between domain name A and Web server before, therefore, after the management control unit is parsed to domain name A again, load-balanced server can deposit the corresponding relation between domain name A and Web server with no longer Slow.Therefore, this allows for that the corresponding relation of substantial amounts of domain name and Web server need not be stored on load-balanced server, so as to save memory space.
Step 13, the management control unit are received as the distribution Web server process requested that the load-balanced server of domain name server service is sent.
The load-balanced server selected by domain name server is after the HTTP for receiving user terminal is asked, and by the URL analyzed in the HTTP request, (Un i form Res ource Loca tor, unified resource is fixed
Position symbol）Information, and according to HOST information in URL（The Hos t headers of H t t p agreements）Obtain the actual domain name that user terminal is asked.Then, the load-balanced server can carry the actual domain name is sent to the management control unit in the distribution Web server process requested.
Step 14, the management control unit are according to the distribution Web server process requested, at least one Web server process is distributed for the load-balanced server so that the HTTP request of the user terminal is sent to the Web server process by the load-balanced server.
In a particular application, domain name is the mark of Web websites, and a domain name can only uniquely correspond to a Web site, therefore, the management control unit is after the distribution Web server process requested is received, Web site information corresponding with the actual domain name of user terminal requests described in the distribution Web server process requested can be obtained according to the domain name stored in the management control unit and the corresponding relation of Web site information first using the actual domain name as index.Then, the Web server process serviced for the Web site is judged whether according to the Web site information.
When existing for the Web server process of the Web site service, the management control unit is at least one Web server process of domain name server-assignment according to the Web server process of storage and the corresponding relation of Web site.When in the absence of the Web server process serviced for the Web site, the management control unit distributes the good business device processes of at least one Web Λ for the Web site again.Now, the Web server host computer system that load is minimum and can be not zero with Web server number of processes is chosen in the Web server host computer system that the management control unit can be all in system, and asks the Web server host computer system to distribute Web server process for the Web site.
It should be noted that in systems in practice, may there is multiple Web servers, i.e. Web server host computer system, and may be run in each Web server host computer system has multiple（1 00 is even more more）Web server process, each Web server process therein monitors different ports.Each load-balanced server, when forwarding the HTTP request of user terminal, is for the forwarding of each Web server process.Therefore, as long as the port numbers for the IP address and internal Web services device process for obtaining Web server host computer system just can each Web server process of unique mark.
Therefore, the management control unit enters for the load-balanced server distribution Web server of the selection
The process of journey, the load-balanced server being exactly possible to as the selection provides the process that the IP address of Web server host computer system and the port numbers of internal Web services device process of service are supplied to the load-balanced server selected by name server to provide service.
Because the management control unit may distribute one or more Web server processes for the load-balanced server of the selection, therefore, the load-balanced server selected by domain name server can select a Web server process according to load-balancing algorithm.Then the load-balanced server of the selection can pass through HTTP, CGI (common gateway interface according to the IP address and the port numbers of internal Web services device process of the Web server host computer system of selection）Or the HTTP request of user terminal is transmitted to the Web server process by other modes.
As seen from the above, the method for realizing many Web application requests scheduling described in the embodiment of the present invention, asked by management control unit according to the domain name mapping of name server, management is scheduled to load-balanced server, i.e., the load-balanced server of service can be provided for name server for the selection of domain name server from multiple load-balanced servers；Simultaneously, by the management control unit according to the distribution Web server process requested by the selected load-balanced server of domain name server, management is scheduled to Web server process, i.e., is the Web server process for the HTTP request that the load-balanced server selection can handle user terminal from multiple Web server processes.Therefore, using the embodiment of the present invention, without the corresponding relation of the domain name of manual configuration user terminal requests and Web server on load-balanced server, so as to handle the application request of a large amount of Web sites simultaneously.
In view of energy conservation characteristic, while the application request of a large amount of Web websites is handled, the management control unit can also be handled as follows：
(1) energy-saving distribution, is carried out to the load-balanced server in system, i.e., according to the total load degree of each load-balanced server in system, increases or decreases the quantity of the load-balanced server of service.
In the process, the total load degree if all of load-balanced server is higher（Such as overall load is more than 70%), and management and dispatching unit will start more（Certain amount）Load-balanced server.Total load degree if all of load-balanced server is relatively low（Such as overall load is less than 40%), and management and dispatching unit will stop certain amount load-balanced server.
Specific implementation can be：When load-balanced server is inadequate, management and dispatching unit regard newly-increased load-balanced server as the load-balanced server to be allocated to name server when for domain name server-assignment load-balanced server；When load surplus needs to stop load-balanced server, management and dispatching unit will not distribute these load balancing for preparing to stop when for domain name server-assignment load-balanced server to name server.When some load-balanced servers no processing HTTP request within a very long time, determine that these load balancing services need stopper, then can just stop by modes such as shutdown.
In addition, the IP address of the good business devices of the load balancing Λ for needing to stop, can distributing to other load-balanced servers by the management control unit.And the management control unit is in distribution, usually the relatively low load-balanced server of selection load is allocated.So, it can prevent user terminal from HTTP request constantly being issued to the load-balanced server stopped.
(2), according to the total load degree of each Web server host computer system in system, the quantity of the Web server host computer system of service is increased or decreased.
During implementing, the management and dispatching unit will calculate overall loading level after each Web server host computer system load is counted.If overall load exceedes the peak of setting, management and dispatching unit will start one or more new Web server host computer systems.If overall load is less than the minimum of setting, then management and dispatching unit stops the one or more Web server host computer systems for controlling low-load, and the Web server process run in these Web server host systems is transferred into other Web server host computer systems.The mode wherein shifted can be, the Web server process serviced for the promising Web site of institute in the Web server host computer system that needs to stop, the management control unit will start new Web server process in other Web server host computer systems, and the new Web server number of processes of startup is consistent with the Web server process for needing to stop.And the Web site service that the new Web server process started is serviced the Web server processes stopped for needs.Then, the management control unit will need in the Web server host computer system stopped all Web server processes to be set to not receive new solicited status again.If necessary to each Web server host computer system for stopping within a period of time such as 1 minute, handle, then the Web server hosts system can be closed, such as shut down, standby without Web request.
(3), the management control unit also can control the life cycle of each Web server process.
In a particular application, each Web server process most multipotency is a Web site service（But it is not necessarily referring to be a Web site service）, it can be that no Web server process is that it is serviced that each Web site, which also not only has when a Web server process is just disposed for its service, but a Web site,.When some Web website just produces access, management and dispatching unit can control a Web server process to be serviced for the Web site.When the visit capacity of the Web site increases to certain amount, the management control unit can control new Web server process for Web site service.When the visit capacity of some Web site reaches certain defined data, the quantity of Web server process is distributed in the way of being rounded by visit capacity/50+1 per second of some Web website for it.
For example when the visit capacity per second of some Web site is 1, will have a Web server process is the Web station services；When visit capacity per second increase is 50, start two Web server processes.And when the visit capacity rank of the Web websites is reduced, management control unit will also reduce the quantity of Web server process.
Based on described above, the change of the Web server number of processes needed according to Web site, the Web server processes life cycle of itself is also possible to be changed.Can not be any Web station services during Web server process initiation, and when some Web site needs increase Web server process to be serviced for it, management and dispatching unit may control this Web server process to load this Web site, this results in Web server processes states and switched to " being X station services ", and when X site volumes are reduced, management and dispatching unit may control this Web server process to stop service, wherein the mode of stopping can killing the process or other modes.
Several processing modes more than, using the method described in the embodiment of the present invention, have reached the effect of energy-conservation.
In addition, in the method described in the embodiment of the present invention, when some Web server process, over-burden, it is for example per second to handle substantial amounts of request or all Web server processes all at work, the management control unit can also adjust the processing state of each Web server process, improve treatment effeciency.Specifically, the management control unit can obtain the current load information of each Web server process first, then according to the current load information, when the utilization rate that the present load of the Web server process is more than or equal to the first default wealthy value namely the Web server process it is high to a certain extent when, determine the Web server process service
Web site whether also have service other Web server processes.If no, distributing Web server process for the Web site；If having, then when the present load of other Web server processes is all higher than being equal to the second default wealthy value, redistribute Web server process, when the present load of other Web server processes, which is less than second, presets wealthy value, the weight of the Web server processes of the Web site service is adjusted to, the reference of the Web server process to select processing user terminal HTTP request as load-balanced server.
Wherein, the described first default wealthy value represents the high degree of some Web server process utilization rate, and the described second default wealthy value represents the low degree of some Web server process utilization rate；, can be according to running situation, by system running state monitoring personnel's sets itself and the described first default wealthy value and second presets wealthy value, such as described first to preset wealthy value can be 70%, and second to preset wealthy value can be 40%.
