Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
When the webserver provides service to client or third party, all need to use buffer memory, the request to the slow database of speed can be reduced by buffer memory, thus user is responded faster.The data that cache stores up normally obtain from database according to user's request.And the server of newly reaching the standard grade or upgrading after server and untreated user request, therefore server does not obtain and data cached information from database, when there being server process user to ask, server sends to the data of user all to obtain from database, because the response time is long when server directly obtains data from database, takies resource large, therefore, when there is a large number of users request, increasing server load, easily making server collapse.Therefore, need to carry out pre-stored to the buffer memory in server after server is reached the standard grade or after upgrading, namely in the buffer memory of server, pre-stored is used for the data of new business.
Possible way has active cache, and active cache refers to that the data of buffer memory in server are initiatively gone to generate by technician; Passive pre-stored is using each request of user all as data cached, and to each data cached setting expired time, if having again identical request in expired time, then refreshes expired time.But the mode of active cache often cost compare is high, because technician do not know which data needs buffer memory, therefore need the forecast model setting up more complicated.
The server of process new business is when initial; the user received asks flow just larger; if directly all users are asked directly to send to and there is no data cached server; can produce server instantaneously and impact; so usually can during this time limit the flow of user's request; abandon a part of user request, be unfavorable for that server process user asks.
For solving the problem, disclosure embodiment is for the server after the larger server of newly reaching the standard grade of user base number or upgrading, by distributing a small amount of user request to the first server for new business, and by other a large amount of user's request dispatching to other servers being used for old business, make first server after initial launch, complete the buffer memory to new business data message, decrease that initial request amount is excessive to impact first server, and reduced-maintenance technician can be subtracted, reduce maintenance cost.
Fig. 1 is the process flow diagram of the method for a kind of buffer memory pre-stored according to an exemplary embodiment, and as shown in Figure 1, the method for buffer memory pre-stored is used for, in server, comprising the following steps.
In a step 101, user's request that client sends is received.
In a step 102, the information on load of first server is obtained; Wherein, first server is for the treatment of new business.Can to be the server of newly reaching the standard grade also can be first server carries out the server after function upgrading to runtime server.
In step 103, when the information on load of first server is less than default first load threshold value, send user's request to first server, instruction first server obtains the data message that also cache user request is asked.
Disclosure embodiment provides a kind of method of buffer memory pre-stored.The server of newly reaching the standard grade larger for user base number or the server after upgrading.When server initial launch, owing to needing to process a large amount of user's requests, if user to be asked the server all directly sent to for new business, then need server from database, obtain mass data information, and the speed that server obtains data message from database is slow, from database, obtains mass data information can make server overload operation.Therefore, send a large amount of user's requests directly to the server for new business to impact to server.For the server after new placed into service device or upgrading, for reducing a large number of users request, server being impacted, all needing a large amount of technician to carry out safeguarding early stage or test in early stage to server.And the scheme that disclosure embodiment provides, by distributing a small amount of user request to the first server for new business, make first server after initial launch, complete the buffer memory to new business data message, decrease that initial request amount is excessive to impact first server, and reduced-maintenance technician can be subtracted, reduce maintenance cost.
In one embodiment, the method also can be implemented as: steps A 1.
In steps A 1, when the information on load duration be between default 3rd load threshold value and default first load threshold value of first server is greater than preset duration threshold value, default first load threshold value is increased to default second load threshold value.Preset the 3rd load threshold value and be less than default first load threshold value.
When the load of first server reduces and tends to balance, can determine that first server process user asks speed and receives the speed that user asks and keep balancing, to illustrate in the buffer memory of now first server that a considerable amount of data message of buffer memory is for first server, now increase the quantity of the user's request distributing to first server, the more data message of pre-stored in first server buffer memory.Therefore, progressively increase the quantity of the user's request distributing to first server, when ensureing that first server is normally run, adding the treatment capacity of first server, completing the pre-stored of server buffer.
In one embodiment, the method also can be implemented as: step B1.
In step bl is determined., when the information on load of first server is more than or equal to default first load threshold value, send user's request to second server, instruction second server obtains the data message that also cache user request is asked.
When the user's number of requests distributing to first server increases to the first load threshold value, illustrate that the processing power of first server arrives threshold value, now, user's request is not sent for the treatment of the second server of new business to other, achieve first server and second server to process user simultaneously and ask, first server only process a small amount of user ask time, decrease remainder user request cannot obtain process situation.
In one embodiment, the method also can be implemented as: step C1.
In step C1, send upgrade file, using second server as first server, for the treatment of new business to second server.
Progressively to upgrade second server, make second server carry out work as first server, process new business.Progressively to upgrade part server, and to a small amount of user's request of the server-assignment after upgrading, pre-stored is carried out to the buffer memory of server, reduce the server of a large number of users request to process new business and produce and impact.
In one embodiment, the method also can be implemented as: step D1-step D2.
In step D1, receive the result for user's request that first server sends;
In step d 2, to the client transmission processing result sending user's request.
Achieve when after server process new business, still can to the object of client Normal Feedback result.
New business upgrading is carried out to one group of server, and needs the server normal process user request after upgrading.Disclosure embodiment provides as under type.
As shown in Figure 2, disclosure embodiment provides a kind of method of buffer memory pre-stored, and concrete implementation step is as follows:
In step 201, upgrade file is sent to first server.
One group of server is divided into 3 parts, first server, second server and the 3rd server, first server sends upgrade file wherein, and the upgrading of instruction first server, for the treatment of new business.
In step 202., user's request that client sends is received.
In step 203, the information on load of first server is obtained.
Information on load, comprising: CPU (central processing unit) utilization rate, committed memory size and the process of operation number.The information on load obtained in the disclosed embodiments is CPU usage.
In step 204, judge whether the information on load of first server is less than default first load threshold value.When the information on load of first server is less than default first load threshold value, perform step 204; When the information on load duration be between default 3rd load threshold value and default first load threshold value of first server is greater than preset duration threshold value, perform step 205; When the information on load of first server is more than or equal to default first load threshold value, perform step 207.
Presetting the first load threshold value is CPU usage 70%.
In step 205, when the information on load of first server is less than default first load threshold value, send user's request to first server, instruction first server obtains the data message that also cache user request is asked.
A small amount of user's request is sent to first server, the CPU usage obtained is judged simultaneously, if CPU usage does not reach 70%, then continue to send user's request to first server, and indicate first server to obtain the data message of asking, and the data message that pre-stored is asked in the buffer memory of first server.
In step 206, judge that the information on load of first server is in default 3rd load threshold value and whether the duration preset between the first load threshold value is greater than preset duration threshold value.When the information on load duration be between default 3rd load threshold value and default first load threshold value of first server is greater than preset duration threshold value, then perform step 207.
Presetting the 3rd load threshold value is CPU usage 50%, and preset duration threshold value is 20S.
In step 207, when the information on load duration be between default 3rd load threshold value and default first load threshold value of first server is greater than preset duration threshold value, default first load threshold value is increased to default second load threshold value.Preset the 3rd load threshold value and be less than default first load threshold value.When the information on load duration be between default 3rd load threshold value and default first load threshold value of first server is less than or equal to preset duration threshold value, the load threshold value of first server is kept to be the first default load threshold value.
When the CPU usage of first server is between 50%-70% during 20S, the processing speed can determining first server with receive the speed that newly assigned user asks and keep balancing, now, the quantity sending to the user of first server to ask can be strengthened, the CPU usage of first server reaches 80%, first server is made to process maximum treatment capacity while guarantee processing speed, the quantity that control sends to the user of first server to ask from less to more, thus set up phase buffer to first server, prevent a large number of users request from impacting first server.
In a step 208, upgrade file is sent, using second server as first server, for the treatment of new business to second server.
Meanwhile, the data of first server buffer memory can also be sent to second server and indicate second server buffer memory.
When the CPU usage of first server remains on 80%, the buffer memory that first server is described pre-stored completes, and the user of first server process asks institute's requesting data information, directly can obtain from buffer memory.Now, upgrading second server, using second server as first server completing steps 203-step 208.Final buffer memory completes the pre-stored of second server buffer memory.
In step 209, when the information on load of first server is more than or equal to default first load threshold value, send user's request to second server, instruction second server obtains the data message that also cache user request is asked.
First server processing speed with receive before user's speed of asking also do not tend to balance, when the amount sending to the user of first server to ask, when reaching 70% of first server CPU usage, need to process redundancy section user request, the server then not carrying out upgrading to other sends user's request, as sent user's request to second server or the 3rd server.The server process of not upgraded by other exceedes user's request of the first load threshold value of first server, ensures while minimizing first server is subject to the impact of a large number of users request, ensures that all user's requests are all processed.
In step 210, the result for user's request that first server sends is received.
Receive the result that first server asks according to user to obtain.
In step 211, to the client transmission processing result sending user's request.
Disclosure embodiment provides a kind of method of buffer memory pre-stored.For after the server used is upgraded, during server process new business, because the data message of new business does not store in the buffer, if the server after upgrading receives a large amount of user's requests, then can impact server.Therefore disclosure embodiment, by first upgrading to first server, and distributing a small amount of user's request to first server, making to complete buffer memory pre-stored in first server.And then to second server upgrading, carry out the step of first server, other servers of then progressively upgrading, finally complete the upgrading of Servers-all.When carrying out pre-stored to the server of new upgrading, the user that the server process of new upgrading is not complete asks, then being processed by other servers, can be the server of having upgraded, also can be the server of not upgrading, make the user received ask all can obtain respective handling.Achieve and still can Deterministic service device normal process user ask in escalation process, the server decreasing new upgrading directly processes a large number of users request and produces impact to server.And can save and safeguard manpower, reduce maintenance cost.
New server of reaching the standard grade is had in the server group of mass clients at one group, and can normal process user request after needing the server of newly reaching the standard grade to reach the standard grade.Disclosure embodiment provides as under type.
As shown in Figure 3, disclosure embodiment provides a kind of method of buffer memory pre-stored, and concrete implementation step is as follows:
In step 301, user's request that client sends is received.
In step 302, the first information on load and second information on load of first server is obtained.
One group of server is divided into two parts, and first server is the server of newly reaching the standard grade for the treatment of new business, and second server is the normal server used for the treatment of old business.Information on load, comprising: CPU (central processing unit) utilization rate, user's number of requests, committed memory size and the process of operation number.First information on load is CPU usage in the disclosed embodiments, and the second information on load is user's number of requests.
In step 303, judge whether the first information on load is more than or equal to default first load threshold value.
When the first information on load of first server is more than or equal to default first load threshold value, continue step 304;
When the first information on load of first server is less than default first load threshold value, continue step 305.
Presetting the first load threshold value is CPU usage 70%.
Step 304, when the first information on load of first server is more than or equal to default first load threshold value, sends user's request to second server.After second server processes user's request, receive the result for user's request that second server sends, and to sending the client transmission processing result of user's request.
Step 305, when the first information on load of first server is less than default first load threshold value, judges whether the second information on load is more than or equal to default second load threshold value;
When the second information on load of first server is less than default second load threshold value, continue step 306,307 and 309;
When the second information on load is more than or equal to default second load threshold value, continue step 306.
Preset the second load threshold value for user's number of requests be 1000.
Step 306, sends user's request to first server.
When the first information on load of first server is less than default first load threshold value, and when the second information on load of first server is less than default second load threshold value, send user's request to first server;
If CPU usage do not reach 70% and user's number of requests do not reach 1000, then continue to send user's request to first server, and indicate first server to obtain the data message of asking, and the data message that pre-stored is asked in the buffer memory of first server.
When the first information on load of first server is less than default first load threshold value, when but the second information on load is more than or equal to default second load threshold value, continue to send user's request, until the first information on load of first server equals default first load threshold value to first server.
First server processing speed with receive before user's speed of asking also do not tend to balance, when the CPU usage of first server does not reach 70%, but when the quantity of user's request has reached 1000, continue to send user's number of requests, until the CPU usage of first server reaches 70% to first server.
Wherein, the first load threshold value and the second load threshold value are equivalent to default first load threshold value in step 203.
Step 307, judges that the first information on load of first server is in default 3rd load threshold value and whether the duration preset between the first load threshold value is greater than default first duration threshold value.
When the first information on load duration be between default 3rd load threshold value and default first load threshold value of first server is greater than default first duration threshold value, continue step 308; When the first information on load duration be between default 3rd load threshold value and default first load threshold value of first server is less than or equal to default first duration threshold value, the first load threshold value of first server is kept to be the first default load threshold value.
Step 308, when the first information on load duration be between default 3rd load threshold value and default first load threshold value of first server is greater than default first duration threshold value, increases to default 5th load threshold value by default first load threshold value.
When the CPU usage of first server is between 50%-70% during 20S, the processing speed can determining first server with receive the speed that newly assigned user asks and keep balancing, now, the quantity sending to the user of first server to ask can be strengthened, the CPU usage of first server reaches 80%, first server is made to process maximum treatment capacity while guarantee processing speed, the quantity that control sends to the user of first server to ask from less to more, thus set up phase buffer to first server, prevent a large number of users request from impacting first server.
Step 309, judges that the second information on load of first server is in default 4th load threshold value and whether the duration preset between the second load threshold value is greater than default second duration threshold value;
The duration be between default 4th load threshold value and default second load threshold value when the second information on load is greater than default second duration threshold value, continues step 310; The duration be between default 4th load threshold value and default second load threshold value when the second information on load is less than or equal to default second duration threshold value, keeps the second load threshold value of first server to be the second default load threshold value.
Step 310, the duration be between default 4th load threshold value and default second load threshold value when the second information on load is greater than default second duration threshold value, and default second load threshold value is increased to default 6th load threshold value.
User's number of requests is between 800-1000 during 20S, the processing speed can determining first server with receive the speed that newly assigned user asks and keep balancing, now, the quantity sending to the user of first server to ask can be strengthened, the quantity of user's request of process reaches 1200, first server is made to process maximum treatment capacity while guarantee processing speed, the quantity that control sends to the user of first server to ask from less to more, thus set up phase buffer to first server, prevent a large number of users request from impacting first server.
Default 6th load threshold value preset in the 5th load threshold value and step 310 in above-mentioned steps 308 is equivalent to default second load threshold value in step 205.
In step 311, the result for user's request that first server sends is received.
Receive the result that first server asks according to user to obtain.
In step 312, to the client transmission processing result sending user's request.
Disclosure embodiment provides a kind of method of buffer memory pre-stored.New server is added in the server group used, in order to the process making the server of newly reaching the standard grade complete pre-stored fast, can send to the server of newly reaching the standard grade and need user to be processed request in a large number, the server of newly reaching the standard grade is made to carry out buffer memory, and in order to ensure that the server of newly reaching the standard grade does not ask to impact by excessive user, when the information on load of the server of newly reaching the standard grade reaches threshold value, send user's request to the server normally used.When achieving the server of reaching the standard grade new in server group, improve the pre-stored speed to new server, and do not need technician to carry out pre-stored to new server, save and safeguard manpower, reduce maintenance cost.
