Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Fig. 1 shows the structural representation of network application system according to an embodiment of the invention.As shown in Figure 1, this network application system comprises: one or more underlying services device 110, the proxy server 120, the front-end server 140 be connected with proxy server 120 and the monitoring server 130 be connected with front-end server 140 with each underlying services device 110 and proxy server 120 that are connected respectively with each underlying services device 110, wherein, buffer 141 is provided with further in this front-end server 140.
Each underlying services device 110 provides one or more application, only schematically illustrate two underlying services devices in FIG, in actual conditions, the quantity of underlying services device can be one or more, when the quantity of underlying services device is multiple, each underlying services device can be respectively used to provide different application, to meet the demand that user accesses multiple application.Alternatively, in order to realize the redundant configuration between underlying services device, also multiple underlying services device can be configured to some groups, each underlying services device often in group underlying services device is all for providing identical application, the application that the underlying services device of different group provides is different, so both meet the demand that user accesses multiple application, achieve redundant configuration often organizing underlying services device inside again.
Proxy server 120 carries out buffer memory with the first predetermined time interval (such as, 5 minutes) to the application that each underlying services device 110 provides, and the application after buffer memory is supplied to front-end server 140.The buffer 141 that front-end server 140 inside is arranged carries out buffer memory with the second predetermined time interval (such as, 1 hour) to the application that each underlying services device 110 provides.Particularly, proxy server 120 and buffer 141 carry out buffer memory to application and refer to that buffer memory applies the result provided, if such as application provides data message, then proxy server 120 and buffer 141 buffer memory is apply the data content corresponding to data message provided.The various caching technologys that proxy server 120 can adopt this area to use, such as, various web caching technology, squid etc., these caching technologys except ensure cache information correct except, also need to consider the problem such as buffer efficiency.And the buffer memory of buffer 141 is mainly it is considered that data cached reliability, and comparatively speaking, buffer efficiency is not considered emphatically, therefore, alternatively, buffer 141 can adopt text file format to store these data contents, to improve the reliability of buffer memory.The result that applying provides can comprise: the district of each game takes information etc.And, when proxy server 120 and the application of buffer 141 buffer memory, if find to read the relevant data failure of application, temporarily do not carry out buffer memory, thus all data ensureing buffer memory are all effective, avoid the situation of cache invalidate data.
Alternatively, the first predetermined time interval above-mentioned is less than the second predetermined time interval, that is, the buffer memory frequency of proxy server 120 is higher, the buffer memory frequency of buffer 141 is lower, and therefore, on proxy server 120, the content of buffer memory may than the content update of buffer memory on buffer 141.So, the application of buffer memory in the preferential invokes proxy server 120 of front-end server 140.In addition, in the present embodiment, in order to simplied system structure, reduce hardware cost, be arranged on front-end server 140 inside for buffer 141 and be described, in actual conditions, also buffer 141 can be arranged independent of front-end server 140, like this, buffer 141 needs to be connected respectively with each underlying services device 110, to obtain every the second predetermined time interval the application that each underlying services device 110 provides.Meanwhile, buffer 141 also will be connected with front-end server 140, so that front-end server 140 can the application of buffer memory on access cache device 141.When buffer 141 is arranged independent of front-end server 140, buffer 141 directly can obtain the application that each underlying services device 110 provides, and need not obtain via proxy server 120 application that underlying services device 110 provides, therefore, buffer memory frequency is more flexible.
Monitoring server 130 detects each underlying services device 110 and proxy server 120, and testing result is sent to front-end server 140.During concrete detection, can every the time interval of presetting, whether normally detect once the application provided in each underlying services device, and whether the operating state of proxy server is normal, in order to Timeliness coverage fault, the default time interval can be arranged little as far as possible, the effect detected during to reach approximate real.
Wherein, when monitoring server 130 detects underlying services device 110, each application provided due to underlying services device all has a URL corresponded, and by accessing this URL, namely may have access to this application.Therefore, when whether normally detecting the application provided in a certain underlying services device, can be detected by the access URL corresponding with the application that this underlying services device provides.If when accessing the URL of this application correspondence that this underlying services device provides, this underlying services device does not respond this URL request or produces mistake, then determine that the application corresponding with this URL is abnormal, otherwise, then determine that the application corresponding with this URL is normal.Such as, the URL that shell script (or other script) visits the application correspondence that a certain underlying services device provides can be passed through, if this underlying services device does not respond this URL request in the given time, or create error message, if such as underlying services device returns 500 or 502 such HTTP error codes etc., then determine that the application corresponding with this URL is abnormal.Here, 500 represent internal server error information, and 502 represent gateway error message, and the error message according to producing tentatively can determine that the application in underlying services device exists the reason of fault.By the URL that each application in regular visit each underlying services device is corresponding, can determine that whether the state of each application in each underlying services device is normal.
When monitoring server 130 detects proxy server 120, also similar mode can be adopted, by sending access request to proxy server, and according to the response of proxy server to this access request, that is: whether return response message or whether the response message that returns correctly judges that whether proxy server is normal.Particularly, occur extremely if the access request that proxy server 120 pairs of monitoring servers 130 send is not replied or replied, then represent that fault itself has appearred in proxy server 120, or, there is network problem.In addition, even if the normal operation of proxy server 120 own, whether the data that monitoring server 130 can also detect buffer memory on proxy server 120 further lost efficacy, when judging data cached whether inefficacy, can adopt in two ways.First kind of way is, judges whether data lost efficacy: such as by transformation parameter, and monitoring server 130 is by a parameter, for example zonearr parameter, what obtain on proxy server is data cached, if zonearr parameter is null value, then represents that get data cached was lost efficacy.The second way is, directly judge data cachedly whether exceeded caching period, such as, suppose that the caching period of proxy server 120 is 5 minutes, namely every 5 minutes buffer memorys once, if before the cache-time of the application of proxy server current cache is shown as 5 minutes, then illustrating that the application of current cache has exceeded caching period, is therefore fail data.When monitoring server 130 judges that data cached on proxy server 120 is for fail data, also can forward end server 140 reporting agencies server 120 abnormal, thus make front-end server can call application from buffer 141.
In addition, in order to ensure the timely reparation of underlying services device and proxy server, after the state of underlying services device or proxy server of determining is abnormal, SMS notification can also be sent to technical staff, so that technical staff can repair it in time.
Front-end server 140 decides to call required application from proxy server 120 or buffer 141 according to the testing result of monitoring server 130, and the application from each underlying services device 110 of calling is combined, and be provided for applying mutual external interface with these, namely user may have access to application corresponding to this external interface by access external interface.
Alternatively, when monitoring server 130 detects that underlying services device 110 and proxy server 120 are all normal, front-end server 140 calls the application in underlying services device 110 via proxy server 120; When monitoring server 130 detects that underlying services device 110 occurs abnormal, front-end server 140 calls the application of underlying services device from proxy server 120; When monitoring server 130 detects proxy server 120 and underlying services device 110 occurs abnormal, front-end server 140 calls the application of underlying services device 110 from buffer 141.By such method of calling, even if underlying services device occurs abnormal, also can should be used for reaching the object of normal service by buffer memory in invokes proxy server, even if also there is exception in proxy server, can also by calling the object that should be used for reaching normal service of buffer memory in buffer.No matter front-end server 140 calls from proxy server 120 application that underlying services device provides, or call from buffer 141 application that underlying services device provides, what it provided applies mutual external interface with these is all the same, therefore, for user, any difference can not be produced.As can be seen here, in the present embodiment, carried out dual buffer memory to the application in underlying services device, that is: proxy server is as the first heavy buffer memory, and buffer, as the second heavy buffer memory, serves the effect of double shield to the normal operation of network application system.Wherein, proxy server is as the first heavy buffer memory, the data of buffer memory in the preferential invokes proxy server of front-end server, and it is higher to call frequency to data cached in proxy server under normal circumstances, therefore, data cached in proxy server, except the requirement of reliability will be met, outside guaranteeing that data are correct, also there is higher requirement to buffer efficiency, to guarantee when the data in underlying services device change, data cached in proxy server can be updated to latest data quickly and accurately, so, the caching period of proxy server when buffer memory generally arranges less, can the data in underlying services device upgrade in time when changing, and, caching technology that proxy server adopts when buffer memory (as, various web caching technology, squid etc.) also need to consider buffer efficiency problem, can promptly be transferred by front-end server.Comparatively speaking, buffer is as the second heavy buffer memory, mainly play the effect of backup, front-end server usually only proxy server go wrong that Shi Caihui calls in buffer data cached, and it is lower to call frequency to data cached in buffer under normal circumstances, therefore, data cached in buffer, higher requirement is had to reliability, to guarantee that data are correct, but it is lower to the requirement of buffer efficiency, so, the caching period of buffer when buffer memory can arrange larger, to reduce taking hardware resource and Internet resources, and, the caching technology that buffer adopts when buffer memory more needs to consider integrity problem usually, therefore text file format can be adopted data cached, to reduce error rate, improve data cached reliability.
In addition, according to one embodiment of present invention, buffer 141 and front-end server 140 are arranged in same physical equipment, like this, even if when causing proxy server 120 not access because of reasons such as network communication failure, buffer 141 also reliably can not can provide the content of buffer memory by the impact of network failure.Can avoid thus causing buffer 141 and proxy server 120 disabled situation simultaneously due to network failure, improve the reliability of system.
In addition, in the present embodiment, when underlying services device is redundant configuration, if there is exception in a underlying services device in one group of underlying services device, the testing result of each underlying services device that proxy server 120 can also be detected by monitoring server 130 learns this abnormal information, thus automatically switch to acquisition application in other the normal underlying services devices from this group underlying services device and buffer memory, thus ensure that data cached correctness.
Fig. 2 shows the flow chart of network application method according to an embodiment of the invention.This network application method can be applicable to the network application system shown in Fig. 1.
As shown in Figure 2, this network application method starts from step S210, in step S210, arranges a proxy server, and this proxy server carries out buffer memory with the first predetermined time interval to the application that one or more underlying services device provides.In step S220, arrange a buffer, this buffer carries out buffer memory with the second predetermined time interval to the application that one or more underlying services device provides.
Above-mentioned steps S210 and step S220 can start to perform simultaneously, also can successively start to perform.Because the second predetermined time interval is greater than the first predetermined time interval usually, therefore, under normal circumstances, first perform step S210, rear execution step S220, and the caching in step S210 and step S220 all performs once every predetermined time interval, therefore, the caching in step S210 and step S220 all belongs to the step that needs continue to perform.Particularly, with carrying out buffer memory, proxy server and buffer correspondence refer to that buffer memory applies the result provided, if such as application provides data message, then proxy server and buffer buffer memory is apply the data content corresponding to data message provided, alternatively, the application that underlying services device provides comprises the application providing data message, then buffer can adopt these data messages of text file format buffer memory, reaches the object of buffer memory application.The result that applying provides can comprise: the district of each game takes information etc.And, when proxy server and the application of buffer buffer memory, if find that buffer memory program reads data failure, temporarily do not carry out buffer memory, thus all data ensureing buffer memory are all effective, avoid the situation of cache invalidate data.
When step S210 and step S220 starts to perform or after starting execution, perform step S230.In step S230, whether normally detect one or more underlying services device, and whether detect proxy server normal.During concrete detection, can every the time interval of presetting, whether normally detect once the application provided in each underlying services device, and whether the operating state of proxy server is normal, in order to Timeliness coverage fault, the default time interval can be arranged little as far as possible, the effect detected during to reach approximate real.Wherein, when detecting underlying services device 110, each application provided due to underlying services device all has a URL corresponded, and by accessing this URL, namely may have access to this application.Therefore, when whether normally detecting the application provided in a certain underlying services device, can be detected by the access URL corresponding with the application that this underlying services device provides.If when accessing the URL of this application correspondence that this underlying services device provides, this underlying services device does not respond this URL request or produces mistake, then determine that the application corresponding with this URL is abnormal, otherwise, then determine that the application corresponding with this URL is normal.Such as, the URL that shell script (or other script) visits the application correspondence that a certain underlying services device provides can be passed through, if this underlying services device does not respond this URL request in the given time, or create error message, if such as underlying services device returns 500 or 502 such HTTP error codes etc., then determine that the application corresponding with this URL is abnormal.Here, 500 represent internal server error information, and 502 represent gateway error message, and the error message according to producing tentatively can determine that the application in underlying services device exists the reason of fault.By the URL that each application in regular visit each underlying services device is corresponding, can determine that whether the state of each application in each underlying services device is normal.When detecting proxy server 120, also similar mode can be adopted, by sending access request to proxy server, and according to the response of proxy server to this access request, that is: whether return response message or whether the response message that returns correctly judges that whether proxy server is normal.In addition, in order to ensure the timely reparation of underlying services device and proxy server, after the state of underlying services device or proxy server of determining is abnormal, SMS notification can also be sent to technical staff, so that technical staff can repair it in time.
After execution of step S230, in step S240, decide to call required application from one or more underlying services device, proxy server or buffer according to testing result, and Combination application is to provide integrated network application system.Alternatively, when detecting that underlying services device and proxy server are all normal, required application is called via proxy server; When detecting that underlying services device occurs abnormal, from proxy server, call required application; And when proxy server being detected and underlying services device occurs abnormal, call required application from buffer.By such method of calling, even if underlying services device occurs abnormal, also can should be used for reaching the object of normal service by buffer memory in invokes proxy server, even if also there is exception in proxy server, can also by calling the object that should be used for reaching normal service of buffer memory in buffer.That is, in the present embodiment, carried out dual buffer memory to the application in underlying services device, that is: proxy server is as the first heavy buffer memory, and buffer, as the second heavy buffer memory, serves the effect of double shield to the normal operation of network application system.
In addition, according to one embodiment of present invention, buffer and front-end server are arranged in same physical equipment, like this, even if when causing proxy server not access because of reasons such as network communication failure, buffer also reliably can not can provide the content of buffer memory by the impact of network failure.Can avoid thus causing buffer and proxy server disabled situation simultaneously due to network failure, improve the reliability of system.That is, the mode that front-end server can be called by this locality obtains the application data of buffer institute buffer memory and without the need to by network service, and for the application of proxy server caches, then front-end server needs to be obtained by network communication mode.
Alternatively, in order to improve the reliability of underlying services device further, the method also comprises the steps: as underlying services device configuring redundancy server accordingly at initial period, to provide the redundancy backup of corresponding underlying services device, like this, when detecting in step S230 that underlying services device occurs abnormal, proxy server switches to be applied from the redundant server buffer memory of correspondence.
According to network application system of the present invention and method, respectively buffer memory is carried out to the application that underlying services device provides by proxy server and buffer, when detecting that underlying services device occurs abnormal, can determine to call application from proxy server or buffer according to testing result.As long as the application solved thus in a underlying services device is broken down will affect the operation of whole network application system, thus cause to provide the problem of complete application function for user, achieving can the application in a certain underlying services device when breaking down, and network application system still can provide the beneficial effect of complete application function to user.Therefore, in network application system of the present invention, the operation of whole system can not be affected because of the exception of a certain equipment (as underlying services device, proxy server), improve the reliability of system.
