Abstract
The application discloses a data processing method, an application server and an application server cluster. The method mainly comprises the steps of selecting, based on locally stored ability messages of other application servers in the same cluster, an application server that is capable of responding to data processing request messages to make the server serve as a central application server when a source application server receives the data processing request messages and is determined not to be able to respond to data processing request messages; and then forwarding the data processing request messages to the selected central application server. Therefore, if a source application server selected by a control server on the basis of a load balancing algorithm or a load balancing configuration strategy cannot meet load demands, other application servers with processing abilities in the same cluster can be selected by the source application server to replace the source application server to respond to data processing request messages, thus solving problems of the prior art that a source application server is forced to respond to data processing request messages to cause load imbalance.
Description
Technical field
The application relates to internet information treatment technology, relates in particular to a kind of methods and applications server and cluster of data processing.
Background technology
Along with the continuous increase of data message amount in the fast development of Internet technology and the Internet, people improve constantly the degree of dependence of the Internet, cause the data access flow of the Internet to increase rapidly.Current most of website (especially ecommerce Lei website) need to provide 24 hours persistent services, critical data that the interruption of any background server or communication failure cause is lost and all can be caused the background server using in very large loss ，Zhe Dui the Internet to propose high-performance, highly reliable requirement.
With respect to the development of network technology, the growth of the speed of each background server deal with data and internal storage access speed is but well below the growth rate of the network bandwidth and application program.The growth that the network bandwidth has brought number of users when increasing, this makes background server hardware resource consumption even more serious, use unit background server is that the mode of a website service can not meet real demand far away, and the performance restriction of current background server has become the bottleneck of Internet technology development.
Under existing Internet architecture, in order to overcome the problems referred to above, propose to set up background server cluster, utilize load-balancing technique when business is carried out, realize background server cluster in the load balancing of each server.
Specific implementation is:
The first step: many application servers are connected to form to an application server cluster by the network equipment, make every application server all provide same or analogous back-end data to process service.
Second step: dispose Control Server at application server cluster front end, its effect is each application server load balancing in the application server cluster of realizing under Control Server control; Specific works mode is: when receiving the data processing request of user Dui Gai website, utilize self load-balancing algorithm to determine the operating state of its each application server under controlling, and the data processing request receiving is assigned to wherein in an application server, indicate this application server return data result message; Or according to the load balancing having configured, the data processing request receiving is distributed in application server cluster, and indication receives the application server return data result message of data processing request.
As can be seen here, each Control Server is independently with respect to application server cluster, when a large amount of data processing request receiving is transmitted to application server, forwarding data process request according to being the load-balancing algorithm of self storage or the load balancing having configured.Wherein, described load-balancing algorithm comprises: sequentially algorithm, proportion algorithm, flow proportional algorithm etc., these algorithms are applicable to the application server of different characteristics.Cause the reason of each application server load imbalance conventionally to have two kinds:
The first situation: the hardware configuration situation that Control Server is carrying out data processing request and divides timing not consider each controlled application server.Although because some application server load is very large, the hardware configuration of this application server is relatively better, the speed of deal with data is also relatively very fast; Equally, although some application server load is very little, the hardware configuration of this application server is relatively low, and the speed of deal with data is also relatively slow.If the load-balancing algorithm that Control Server is only stored according to self or the load balancing having configured, be transmitted to definite application server by the data processing request receiving, there will be each application server to occur the situation of load imbalance.
For example: the current load condition of application server A is 50%, and the current load condition of application server B is 75%, but the hardware configuration of application server B is far away higher than application server A; Suppose that Control Server receives a data processing request, the load-balancing algorithm of storing according to body or the load balancing having configured are definite distributes to application server A by this data processing request, if but this data processing request is distributed to after application server A, the load of application server A will be strengthened, the processing speed of application server A is declined, and cause each application server load imbalance.
Second case: Control Server can not well be assessed its needed disposal ability to the data processing request receiving, divides timing also cannot consider whether application server meets its disposal ability.Because different data processing request shared system resource when processed is different, therefore, the disposal ability of the application server of processing is required also different.When Control Server is forwarded to an application server according to the load-balancing algorithm of self storage or the load balancing that configured by data processing request, owing to not considering the disposal ability of the needed application server of this data processing request, may cause the application server that receives data processing request to need at short notice the data volume of processing too much, traffic pressure is excessive, affects the efficiency of these application server processes data.
For example: in the back-end data treatment system of Yi Ge website, Control Server receives a plurality of synchronous processing requests and a plurality of asynchronous process request simultaneously, Control Server determines that according to the load-balancing algorithm of self storage asynchronous process request processed by application server A, but, the pending asynchronous process request of current application server A is more, and the required system resource of the asynchronous process request that Control Server sends is relatively large, therefore, when application server A receives after this asynchronous process request, a large amount of system resource will be taken, cause application server A deal with data pressure to increase, affect the speed of data processing, and then make to occur between each application server the phenomenon of load imbalance.
As can be seen here, there is the problem of load imbalance in Control Server according to the data handling utility server of load-balancing algorithm or the selection of load balancing collocation strategy.
Summary of the invention
The embodiment of the present application provides a kind of methods and applications server and cluster of data processing, when solving the data handling utility server that prior art selected according to load-balancing algorithm or load balancing collocation strategy by Control Server, still may there is the problem of application server load imbalance.
A method for data processing, the method comprises:
Source application server, when receiving data processing request message, judges the ability self whether with this data processing request message of response;
When source application server is determined the ability self without this data processing request message of response, according to the ability information of other application servers in the same cluster of this locality storage, selection has the application server of this data processing request message capability of response as middle application server, and described data processing message is transmitted to the middle application server of selection.
, this application server comprises:
Judge module, for when receiving data processing request message, judges the ability self whether with this data processing request message of response;

Compared with prior art, source application server is not simply according to receiving data processing request message, directly to process, and returns to response results message, but judge self whether to there is the ability of processing this data processing request message, when not possessing this data processing request message of processing, this data processing request message is transmitted to definite application server with this data processing request ability, while having avoided like this Control Server can not meet loading demand according to the source application server of load-balancing algorithm or the selection of load balancing collocation strategy, Ke You source application server is selected other application servers with disposal ability in same cluster and is carried out the response of alternate source application server to data processing request message, this has solved forces in prior art to come response data to process the problem of the load imbalance that request message causes by source application server, improved treatment effeciency.
Below in conjunction with Figure of description, each embodiment of the application is described in detail.
Embodiment mono-:
As shown in Figure 1, it is the schematic flow sheet of method of a kind of data processing of the embodiment of the present application one, and described method comprises:
Step 101: source application server, when receiving data processing request message, judges the ability self whether with this data processing request message of response, if so, returns to response success message; Otherwise, perform step 102.
In this step 101, described source application server refers to the application server of the data processing request message that receives Control Server transmission.
The described response success message of returning can refer to that source application server is back to Control Server using the result of data processing request message as response success message, is returned to the terminal that sends data processing request message by Control Server.
It should be noted that, the application server in each embodiment of the application has the ability of the data processing request that receives of judgement required system resource size when processed, and has to determine currently self whether can respond the ability of this data processing request message.
The ability that described response data is processed request message refers to according to current application server hardware occupation condition, determines whether to also have sufficient system resource for the treatment of the data processing request receiving.
Step 102: when source application server is determined the ability self without this data processing request message of response, according to the ability information of other application servers in the same cluster of this locality storage, selection has the application server of this data processing request message capability of response as middle application server, and described data processing request message is transmitted to the middle application server of selection.
Wherein, when each application server is set up to cluster, basic hardware and software configuration information for each application server in this application server cluster of each application server configuration, comprising: IP address, the listening port of internal load service etc., and this configuration information is stored in to this locality of each application server, and the application server in cluster upgrades while changing, such as increasing application server or the application server etc. that rolls off the production line.
Particularly, the mode that in cluster, arbitrary application server obtains the ability information of other application servers in same cluster is:
Application server is periodically to the state information of other application servers broadcast in cluster self, and periodically receive the state information of other application servers broadcast in cluster, cluster identity, server identification and the ability information of in described state information, having carried the application server place cluster of broadcasting status messages.
Described ability information comprises: the load condition of current application server, each hardware state parameter and software program running state information etc.
It should be noted that, in the same cluster of described local storage, the ability information of other application servers is close to the state information that receives each application server receiving in the cycle of data processing request message.
Wherein, load condition can represent by the form of percentage, also can represent by concrete load value; Each hardware state parameter can be occupancy, internal memory use amount of cpu resource etc.; Software program state information can be the quantity of current use software program, and the stock number that software program operation takies etc., specifically respectively join numerical representation information and be not specifically limited here.
More preferably, described load condition can obtain by the mode of computational load value, is specially:
The first step: for distributing different weighted values according to the function of application server for its hardware resource and software station resource;
Second step: when broadcast cycle is about to arrive, determine the operation parameter of this application server hardware resource and the operation parameter of software resource;
The 3rd step: utilize described definite weighted value, carry out weighted sum operation, obtain the load value of this this broadcast cycle of application server.
More preferably, the application server in same cluster is divided into a plurality of groups, in each group, comprises a plurality of application servers; And set up Socket between the application server in each group and connect, and determine the running status of application server in group by sending keep-alive instruction (keep-alive), and the regular synchronous state information of each application server in group.
It should be noted that in ，Ge group, setting up the application server that Socket connects becomes standby host mutually, it is the highest that the application server that has a standby host relation can be set its priority when selecting intermediate server.
Particularly, source application server judges in the group of place whether exist and have the application server that responds this data processing request message capability, if, in the group of Ze Cong place, select application server as middle application server, otherwise select application server as middle application server in other groups.
Step 103: described middle application server judges the ability self whether with this data processing request message of response, if so, performs step 104; If not, perform step 105.
In step 103, described middle application server judges that the mode of the ability self whether with this data processing request message of response is identical with the mode of source application server judgement.
Step 104: described middle application server responds this data processing request message ，Bing Xiang source application server as object application server and returns to response success message.
In step 104, described intermediate server is by judging the ability self with this data processing request message of response of determining, this intermediate server responds this data processing request message, and result is returned to source server as response success message, and then by source application server, the response success message receiving is back to Control Server.
It should be noted that, because data processing request message is received by source application server, but the processing of data processing request message is not by source application server processes, but according to ability information, determine other application servers that can respond this data processing request message in the same cluster of being selected by source application server, therefore the middle application server of, processing this data processing request message is called as the object application server of this data processing request message.
Step 105: described middle application server returns to response failed message to source application server.
In step 104, described intermediate server is by judging the ability self without this data processing request message of response of determining, this intermediate server returns to response failed message to source application server, and then by source application server, the response failed message receiving is back to Control Server.
By the scheme of the embodiment of the present application one, by source application server when receiving data processing request message, judge the ability self whether with this data processing request message of response, when determining the ability self without this data processing request message of response, according to the capabilities message of other application servers in the same cluster of this locality storage, selection has the middle application server of this data processing request message capability of response, and described data processing request message is transmitted to the middle application server of selection, avoided like this problem in prior art, the problem includes: the problem of load imbalance between each application server that the required disposal ability of the disposal ability of not considering application server or data processing request causes.
It should be noted that, when the intermediate server of source application server selection has the ability of this data processing request message of response, this middle application server responds this data processing request message ，Bing Xiang source application server as object application server and returns to response success message; When the intermediate server of source application server selection does not have the ability of this data processing request message of response, this need to reselect other application servers of ability during as middle application server with this data processing request message of response, and the mode reselecting has two kinds: application server definite middle application server in a kind of Shi You source continues to select to have other application servers of ability of this data processing request message of response as middle application server; Another kind is to source application server, to return to other application servers that failed message Hou，You source application server selects to have the ability that responds this data processing request message again at the intermediate server without the ability of this data processing request message of response.
By embodiment bis-and embodiment tri-, describe in detail and reselect other application servers of the ability with this data processing request message of response as two kinds of modes of middle application server respectively below.
Embodiment bis-:
As shown in Figure 2, it is the flow chart of method of a kind of data processing of the embodiment of the present application two, suppose to have comprised in current application server cluster these five application servers of source application server, application server A, application server B, application server C and application server D, wherein, source application server, application server A and application server B are divided in same a small group, and the method for carrying out data processing by these five application servers comprises:
Step 201: source application server, when receiving data processing request message, judges the ability self whether with this data processing request message of response, if so, returns to response success message; Otherwise, perform step 202.
Step 202: when source application server is determined the ability self without this data processing request message of response, according to the ability information of other application servers in the same cluster of this locality storage, selection has the application server of this data processing request message capability of response as middle application server, and described data processing request message is transmitted to the middle application server of selection.
Particularly, source application server determines that the concrete steps of middle application server comprise:
The first step: source application server is when determining the ability self without this data processing request message of response, according to the ability information of other application servers in the same cluster of this locality storage, determine that the application server that can respond this data processing request message is: application server A, application server B and application server C;
Second step: source application server selects an application server as middle application server from the application server that can respond this data processing request message of determining, and described data processing request message is transmitted to the middle application server of selection.
Particularly, source application server is according to the state information of each application server broadcast in the cycle that approaches this data processing request message of reception most receiving, selecting application server A is middle application server, and described data processing request message is transmitted to the middle application server A of selection.
More preferably, source application server determines that the concrete steps of middle application server comprise:
The first step: source application server is when determining the ability self without this data processing request message of response, according to the ability information of other application servers in the same cluster of this locality storage, determine that the application server that can respond this data processing request message is: application server A, application server B and application server C.
Second step: source application server selects to belong to other application servers of same a small group, i.e. application server A and application server B from the application server that can respond this data processing request message of determining.
The 3rd step: source application server selects an application server that can respond this data processing request message as middle application server again from same a small group, and described data processing request message is transmitted to the middle application server of selection.
Particularly, source application server is according to the state information of each application server broadcast in the cycle that approaches this data processing request message of reception most receiving, selection is middle application server with the application server A in a small group, and described data processing request message is transmitted to the middle application server A of selection.
It should be noted that, because source application server, application server A and application server B belong in same a small group, with having set up Socket passage in a small group between each application server, facilitate Forward-reques message and response message, the preferential intermediate server from selecting request message to forward in same a small group, the load balancing with each application server of a small group can not only be met in cluster, and the response efficiency of request message can also be improved.
Step 203: middle application server A judges the ability self whether with this data processing request message of response, if so, performs step 204; Otherwise, perform step 205.
In this step 203, described middle application server A adopts embodiment Yi Zhong source application server to judge that the method self whether with the ability that responds this data processing request message judges self-ability.
Step 204: described middle application server A responds this data processing request message ，Bing Xiang source application server as object application server and returns to response success message, end operation.
Step 205: described middle application server A, according to the ability information of other application servers in the same cluster of this locality storage, reselects an application server B with this data processing request message capability of response as middle application server.
Described middle application server A selects the principle of next middle application server identical with the principle of source application server: preferential selection with the application server in a small group with this data processing request message capability of response.
The described application server reselecting is the server of same cluster Zhong Chu source application server and the middle application server part selected.
Step 206: middle application server B judges the ability self whether with this data processing request message of response, if so, performs step 207; Otherwise, perform step 208.
In this step 206, described middle application server B adopts embodiment Yi Zhong source application server to judge that the method self whether with the ability that responds this data processing request message judges self-ability.
Step 207: described middle application server B responds this data processing request message ，Bing Xiang source application server as object application server and returns to response success message, and end operation.
It should be noted that, middle application server B is after the data processing request message to receiving is processed, using result as response success message, send to the middle application server A that forwards this data processing request message, and by middle application server, response success message is sent to source application server.
Step 208: described middle application server B traversal is determined the application server that can respond this data processing request message according to ability information, final not definite object application server that can be used as, now, middle application server B returns to response failed message to source application server.
Particularly, because intermediate server B is according to the ability information of other application servers in the same cluster of this locality storage, determine with middle application server B and belong to the application server in same a small group without this data processing request message capability of response, therefore middle application server B need to select application server as middle application server in other groups, the mode of selecting is identical by the mode of server with a small group planted agent with selection, does not describe here.
It should be noted that, at middle application server B, in traversal, according to ability information, determine while can respond the application server of this data processing request message, determine that application server C, application server D do not possess the ability that can respond this data processing request message, therefore, this data processing request message can be transmitted to application server C and application server D, but first response failed message is returned to the middle application server A that forwarding data is processed request message, by middle application server A, to source application server, return to response failed message.
Embodiment tri-:
As shown in Figure 3, it is the structural representation of method of a kind of data processing of the embodiment of the present application three, suppose to have comprised in current application server cluster these five application servers of source application server, application server A, application server B, application server C and application server D, wherein, source application server, application server A and application server B belong to same a small group, and the method for carrying out data processing by these five application servers comprises:
Step 301: source application server, when receiving data processing request message, judges the ability self whether with this data processing request message of response, if so, returns to response success message; Otherwise, perform step 302.
It should be noted that, source application server determines self not have response during this data processing request message capability, and the principle of whether selecting this data processing request to be transmitted to other application server processes is the time of the response failure result of returning to this data processing request message of determining according to the attribute information of the data processing request message receiving.
If the attribute information of the data processing request message the receiving business ，Ze source application server that to be requirement of real-time higher is being determined currently while not having this data processing request message capability of response, directly return to response failed message;
If the attribute information of the data processing request message receiving is the business that requirement of real-time is lower, source application server determine current while not thering is this data processing request message capability of response, the application server can in same a small group by the data processing request message receiving is transmitted to this data processing request message capability of response is processed, and the principle that selection is transmitted to other application servers is to select to have the application server of this data processing request message capability of response.
Step 302: when source application server is determined the ability self without this data processing request message of response, according to the ability information of other application servers in the same cluster of this locality storage, selection has the application server of this data processing request message capability of response as middle application server, and described data processing request message is transmitted to the middle application server of selection.
Particularly, source application server determines that the concrete steps of middle application server comprise:
The first step: source application server is when determining the ability self without this data processing request message of response, according to the ability information of other application servers in the same cluster of this locality storage, determine that the application server that can respond this data processing request message is: application server A, application server B and application server C;
Second step: source application server selects an application server as middle application server from the application server that can respond this data processing request message of determining, and described data processing request message is transmitted to the middle application server of selection.
Particularly, source application server is according to the state information of each application server broadcast in the nearest cycle receiving, and selecting application server A is middle application server, and described data processing request message is transmitted to the middle application server of selection.
More preferably, source application server determines that the concrete steps of middle application server comprise:
The first step: source application server is when determining the ability self without this data processing request message of response, according to the ability information of other application servers in the same cluster of this locality storage, determine that the application server that can respond this data processing request message is: application server A, application server B and application server C.
Second step: source application server selects to belong to other application servers of same a small group, i.e. application server A and application server B from the application server that can respond this data processing request message of determining.
The 3rd step: source application server selects an application server that can respond this data processing request message as middle application server again from same a small group, and described data processing request message is transmitted to the middle application server of selection.
Particularly, source application server is according to the state information of each application server broadcast in the cycle that approaches this data processing request message of reception most receiving, selection is middle application server with the application server A in a small group, and described data processing request message is transmitted to the middle application server A of selection.
It should be noted that, because source application server, application server A and application server B belong in same a small group, with having set up Socket passage in a small group between each application server, facilitate Forward-reques message and response message, the preferential intermediate server from selecting request message to forward in same a small group, the load balancing with each application server of a small group can not only be met in cluster, and the response efficiency of request message can also be improved.
Step 303: described middle application server A judges the ability self whether with this data processing request message of response, if, described middle application server responds this data processing request message as object application server, Bing Xiang source application server returns to response success message, and end operation;
Otherwise described middle application server A returns to response failed message to source application server.
Particularly, if the attribute information of the data processing request message receiving is the business that requirement of real-time is higher, source application server determine current while not thering is this data processing request message capability of response, directly return to response failed message, for example: the data processing request receiving is payment transaction request, if the response time is excessively of a specified duration, may cause the phenomenon that occurs that a transaction is repeatedly paid, now, source application server is when receiving payment transaction request, determine and currently do not there is response during this data processing request message capability, directly return to response failed message, refuse this payment transaction request,
If the attribute information of the data processing request message receiving is the business that requirement of real-time is lower, source application server determine current while not thering is this data processing request message capability of response, can, by the data processing request message receiving being transmitted to the application server in same a small group with this data processing request message capability of response, wait for the result of other application servers.
For example: the data processing request receiving is the request message of linked web pages, source application server is receiving the request message of linked web pages, and determine current while not thering is this data processing request message capability of response, by selecting and determining, this request message is transmitted to the application server with this data processing request message capability of response, by this application server processes, if this application server is current, can respond this data processing request, Ze Xiang source application server returns to response success message, if this application server is current, can not respond this data processing request, by selecting and determine that this request message is transmitted to the next application server with this data processing request message capability of response, by the application server processes of selecting, carry out successively aforesaid operations, until the hop count of this request message reaches the threshold value of setting, by current middle application server, to the application server of Forward-reques message, return to response failed message to source application server successively.
The threshold value of described setting can be according to the make out the scale of application server cluster, also can determine according to real network state, and the size of threshold value is not specifically limited here.
More preferably, source application server is when receiving data processing request message, determine self do not have mutually should data processing request message ability time, according to the ability information of other application servers in the same cluster of this locality storage, select an application server with this data processing request message capability of response as middle application server, by this middle application server, judged the ability self whether with this data processing request of response.
When this middle application server is determined the ability self without this data processing request of response, to source application server, return to response failure, now, source application server will no longer continue to select other application server, but directly the response failed message receiving is returned to Control Server, can improve like this efficiency of whole application server cluster deal with data.
Step 304: source application server is when receiving the response failed message that middle application server A returns, according to the ability information of other application servers in the same cluster of this locality storage, reselect an application server B with this data processing request message capability of response as middle application server.
Due to the application server B in addition in same a small group with source application server, therefore, source application server can also adopt the mode of step 302 using application server B as middle application server, and this data processing request is transmitted to middle application server B.
Wherein, the application server that described source application server reselects is the middle application server for having selected not.
Step 305: described middle application server B judges the ability self whether with this data processing request message of response, if, described middle application server B responds this data processing request message as object application server, Bing Xiang source application server returns to response success message, and end operation;
Otherwise described middle application server B returns to response failed message to source application server.
Step 306: source application server is when receiving the response failed message that middle application server B returns, judgement traversal determines that according to the ability information of storage the number of times of the application server that can respond this data processing request message reaches setting threshold value, if so, return to response failed message to Control Server; Otherwise, perform step 307.
Described setting threshold value can be determined according to the attribute of the data processing request message receiving, and also can determine according to the actual needs, is not specifically limited here.
Step 307: source application server, according to the ability information of other application servers in the same cluster of this locality storage, reselects an application server C with this data processing request message capability of response as middle application server.
Because the application server coexisting in Yi Ge group with source application server does not have the ability of this data processing request message of response, therefore, source application server selects application server as middle application server in other groups.
Step 308: described middle application server C judges the ability self whether with this data processing request message of response, if, described middle application server responds this data processing request message as object application server, Bing Xiang source application server returns to response success message, and end operation;
