Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Need to prove that in embodiments of the present invention, the concept of " in a large number " refers to 10,000,100,000 even more.Certainly, the embodiment of the invention also can be applicable among the scene of prior art, thereby reaches better effect.
For handling the application request of a large amount of Web websites simultaneously, as shown in Figure 1, the embodiment of the invention realizes that the method for many Web application request scheduling comprises the steps:
Wherein, in described DNS request, the domain name of portability user terminal requests is carried out domain name mapping with convenient described management control unit.In addition, in described DNS request, also can include the IP address information of source address, so that the domain name server determines to send to it user terminal of domain name analysis request.
Step 12, described management control unit are at least one load-balanced server of domain name server-assignment according to the domain name analysis request.
In real system, the quantity of described load-balanced server may have 100 even more.The initiatively monitoring in real time or monitor load data and the operation conditions of each load-balanced server in real time according to the information that each load-balanced server reports of described management control unit selects to provide for the domain name server load-balanced server of service then.Wherein said load data can comprise the CPU usage of each load-balanced server, memory usage, bandwidth utilization rate etc.
When selecting load-balanced server, described management control unit can be selected according to load-balancing algorithm.For example described management control unit can be according to the loading condition of each load-balanced server in the system, select at least one minimum load-balanced server of load, and the IP address of described load-balanced server and load information be stored in the load-balanced server tabulation, send described load-balanced server tabulation to the domain name server then, make the domain name server select load-balanced server according to the load information of each load-balanced server.
Wherein, described load information can comprise the weight of the load-balanced server of selection, and at this moment, the domain name server can directly be selected load-balanced server according to described weight.Perhaps described load information can comprise the loading condition of the load-balanced server of selection.When described load information comprises the loading condition of load-balanced server of selection, calculate the weight of each load-balanced server by the domain name server according to described loading condition, and then select load-balanced server according to described weight.Perhaps described load information also can comprise weight and the loading condition of the load-balanced server of being selected by described management control unit simultaneously, and this moment, the domain name server still can directly be selected load-balanced server according to described weight.
In addition, after the DNS request that at every turn receives user terminal, all will can offer the information of the load-balanced server of service to management control unit inquiry by the domain name server, the domain name server also can be preserved described load-balanced server tabulation.
And when carrying the domain name of user terminal requests in the domain name analysis request, the domain name that described management control unit also can be asked described user terminal after receiving the domain name analysis request is resolved.Owing to need the domain name of cache user terminal request and the corresponding relation of Web server at load-balanced server, after described management control unit is resolved certain domain name A of user terminal requests, when the identical domain name of user terminal requests is arranged again, since before buffer memory cross corresponding relation between this domain name A and the Web server, therefore, after described management control unit was resolved this domain name A again, load-balanced server is the corresponding relation between buffer memory this domain name A and the Web server no longer.Therefore, this just makes needn't store a large amount of domain names and the corresponding relation of Web server on the load-balanced server, thereby saves memory space.
Step 13, described management control unit are received as the distribution Web server process requested of the load-balanced server transmission of domain name server service.
The load-balanced server of being selected by the domain name server is after the HTTP request that receives user terminal, with URL (the Uniform Resource Locator that analyzes in the described HTTP request, URL(uniform resource locator)) information, and obtain the actual domain name that user terminal is asked according to HOST information among the URL (the Host header of Http agreement).Then, described load-balanced server can be carried at described actual domain name in the described distribution Web server process requested and send to described management control unit.
In concrete the application, domain name is the sign of Web website, and domain name can only be unique corresponding to a Web website, therefore, described management control unit is after receiving described distribution Web server process requested, can be index with described actual domain name at first, obtain the Web site information corresponding with the actual domain name of user terminal requests described in the described distribution Web server process requested according to the domain name of in described management control unit, storing and the corresponding relation of Web site information.Then, judge whether to exist for the Web server process of described Web website service according to described Web site information.
When existing for the Web server process of described Web website service, described 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 website.When not existing for the Web server process of described Web website service, described management control unit distributes at least one Web server process for described Web website again.At this moment, described management control unit can be by choosing the non-vanishing Web server host computer system of the minimum and available Web server number of processes of load in the Web server host computer systems all in the system, and to ask described Web server host computer system be that described Web website distributes the Web server process.
Need to prove, in real system, may there be a plurality of Web servers, i.e. the Web server host computer system, and may move a plurality of (100 even more) Web server process in each Web server host computer system, each Web server process is wherein monitored different ports.Each load-balanced server is transmitted at each Web server process when the HTTP request of transmitting user terminal.Therefore, just can each Web server process of unique identification as long as obtain the port numbers of the IP address of Web server host computer system and internal web server processes.
Therefore, described management control unit is the process that the load-balanced server of described selection distributes the Web server process, can provide the IP address of Web server host computer system of service and the port numbers of internal web server processes to offer the process that the described load-balanced server of being selected by name server provides service exactly for the load-balanced server of described selection.
Because described management control unit may distribute one or more Web server processes for the load-balanced server of described selection, therefore, the load-balanced server of being selected by the domain name server can be selected a Web server process according to load-balancing algorithm.The load-balanced server of described selection can be according to the IP address of the Web server host computer system of selecting and the port numbers of internal web server processes then, by HTTP, CGI (common gateway interface) or other modes the HTTP request of user terminal is transmitted to described Web server process.
As seen from the above, the method of many Web of the described realization of embodiment of the invention application request scheduling, by the domain name mapping request of management control unit according to name server, load-balanced server is carried out dispatching management, namely from a plurality of load-balanced servers, select to provide for name server the load-balanced server of service for the domain name server; Simultaneously, by the distribution Web server process requested of described management control unit basis by the selected load-balanced server of domain name server, the Web server process is carried out dispatching management, namely is the Web server process that described load-balanced server is selected HTTP request that can the process user terminal from a plurality of Web server processes.Therefore, utilize the embodiment of the invention, need not the domain name of manual configure user terminal request on load-balanced server and the corresponding relation of Web server, thereby can handle the application request of a large amount of Web websites simultaneously.
Consider energy conservation characteristic, in the application request of handling a large amount of Web websites, described management control unit also can carry out following processing:
(1), the load-balanced server in the system is carried out energy-saving distribution, namely according to the total load degree of each load-balanced server in the system, increase or reduce the quantity of the load-balanced server of service.
In this process, if the total load degree of all load-balanced servers is than higher (surpassing 70% as overall load), the management and dispatching unit will start the load-balanced server of more (somes).If the total load degree of all load-balanced servers lower (being lower than 40% as overall load), the management and dispatching unit will stop some load-balanced servers.
Specific implementation can be: when load-balanced server was not enough, the management and dispatching unit will increase load-balanced server newly as the load-balanced server of giving name server to be allocated when being domain name server-assignment load-balanced server; When the load surplus need stop load-balanced server, the management and dispatching unit was when being domain name server-assignment load-balanced server, with the load balancing that can not distribute these preparations to stop to name server.When some load-balanced server is not handled the HTTP request in a very long time, determine that these load balancing services need stopper, so just can stop by modes such as shutdown.
In addition, the IP address of the load-balanced server that described needs stop can be distributed to other load-balanced server by described management control unit.And described management control unit generally is to select the lower load-balanced server of load to distribute in a minute timing.Like this, can prevent that user terminal from constantly issuing HTTP request the load-balanced server that has stopped.
(2), according to the total load degree of each Web server host computer system in the system, increase or reduce the quantity of the Web server host computer system of service.
In the specific implementation process, described management and dispatching unit will calculate whole loading level after each Web server host computer system load of statistics.If overall load surpasses the peak of setting, then the management and dispatching unit will start one or more new Web server host computer systems.If overall load is lower than the minimum of setting, then the management and dispatching unit one or more Web server host computer systems that will control low load stop, and the Web server process of moving on these Web server host computer systems is transferred to other Web server host computer systems.Wherein the mode of Zhuan Yiing can be, on the Web server host computer system that stops for needs the Web server process of promising Web website service, described 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 that need stop.And the Web website service that the new Web server process that starts will be served for the Web server process that needs stop.Then, all Web server processes are set to and do not receive new solicited status on the Web server host computer system that described management control unit stops needs again.Each the Web server host computer system that stops if desired as 1 minute, has not had the Web request to handle in a period of time, and then this Web server host computer system can be closed, as shutdown, standby etc.
(3), described management control unit also can be controlled the life cycle of each Web server process.
In concrete the application, the multipotency of each Web server process is a Web website service (but being not that finger must be the service of a Web website), each Web website is not only to have a Web server process to be its service yet, but a Web website can not have the Web server process to be its service when just being deployed.When certain Web website had just produced visit, the management and dispatching unit can be controlled a Web server process and be this Web website service.When the visit capacity of described Web website was increased to some, described management control unit can be controlled new Web server process and come to be this Web website service.When the visit capacity of certain Web website reaches certain predetermined data, the mode that can round by the per second visit capacity/50+1 of certain Web website is its quantity of distributing the Web server process.
For example the per second visit capacity of certain Web website is 1 o'clock, will have a Web server process to be this Web website service; When the per second visit capacity increases to 50, start two Web server processes.And when the visit capacity rank of this Web website reduces, management control unit also will reduce the quantity of Web server process.
Based on described above, according to the variation of the Web server number of processes of Web website needs, the life cycle of Web server process self also might be changed.It can not be any Web website service during the Web server process initiation, and when certain Web website need increase the Web server process and serves for it, the management and dispatching unit may be controlled this Web server process and load this Web website, this just causes the Web server process status to transfer " for the service of x website " to, and when the minimizing of x site volume, the management and dispatching unit may be controlled this Web server process and stop service, and the mode that wherein stops can be to kill this process or other modes.
By above several processing modes, utilize the described method of the embodiment of the invention, reached energy-conservation effect.
In addition, in the described method of the embodiment of the invention, over-burden when certain Web server process, for example per second need be handled a large amount of requests or all Web server processes all at work, described management control unit also can be regulated the treatment state of each Web server process, improves treatment effeciency.Specifically be, described management control unit can at first obtain the present load information of described each Web server process, then according to described present load information, also namely the utilance of this Web server process is high to a certain degree the time more than or equal to first predetermined threshold value when the present load of described Web server process, and whether the Web website of determining described Web server process service also has other Web server processes of service.If do not have, then be that described Web website distributes the Web server process; If have, then when the present load of described other Web server processes during all more than or equal to second predetermined threshold value, redistribute the Web server process, when the present load of described other Web server processes during less than second predetermined threshold value, be adjusted into the weight of the Web server process of described Web website service, with the reference of the Web server process of selecting process user terminal HTTP request as load-balanced server.
Wherein, described first predetermined threshold value is represented the high degree of certain Web server process utilance, and described second predetermined threshold value is represented the low degree of certain Web server process utilance; And described first predetermined threshold value and second predetermined threshold value can be according to system's practical operation situation, and personnel set up on their own by the system running state monitoring, and for example described first predetermined threshold value can be 70%, the second predetermined threshold value and can be 40%.
