Embodiment bis-
The embodiment of the present invention provides a kind of overload protection method of server, and in conjunction with the content of above-described embodiment one, the present embodiment be take executive agent as server is example, and the method that the present embodiment is provided is illustrated.Referring to Fig. 2, the method flow that the present embodiment provides comprises:
201: receive pending request, and obtain the current system load information of server;
Particularly, the present embodiment is not done concrete restriction to the type of the pending request receiving, and includes but not limited to connection request, obtains services request etc.The present embodiment is not done concrete restriction to the content of the current system load information of server yet, include but not limited to the CPU(Central Processing Unit that server is current, central processing unit) utilization rate, memory usage, at least one in network bandwidth utilization rate etc.About obtaining the mode of the current system load information of server, the present embodiment is not done concrete restriction equally, includes but not limited to following two kinds of modes:
First kind of way: directly obtain the current system load information of server;
For first kind of way, the present embodiment is not done concrete restriction to directly obtaining the mode of the current system load information of server, include but not limited to the concrete service condition of the server local resource that obtains according to mensuration, calculate the utilization rate of every resource, using the utilization rate of every the resource calculating as the current system load information of the server getting.
For example, if the local resource of utilization rate to be determined is internal memory, the total 8GB of internal memory one on server, at current some time points, network application on server has taken 4GB internal memory altogether, by 4, divided by 8 memory usages that can obtain on current server, be now 50%, using the memory usage calculating 50% as the system load information getting.
The second way: obtain in advance the also system load information of storage server, obtain the current system load information of server according to the system load information of pre-stored server.Wherein, obtain in advance the mode that the system load information of server adopts and can carry out according to above-mentioned first kind of way, system load information can be stored in the storage medium on server after getting the system load information of server.Afterwards, according to whether the system load information of pre-stored server is expired, determine how to obtain the current system load information of server, specifically can be divided into following two kinds of situations:
The first situation, when the system load information of pre-stored server is expired, obtains the system load information of server again, and using the system load information getting as the current system load information of server;
Wherein, judging whether the system load information of pre-stored server is expired takes following mode:
A time cycle is set, when the system load information of pre-stored server, can records the concrete time of this system load information of storage simultaneously.When having new pending request to arrive, obtain the concrete time now, deducted to the concrete time of the storage system load information of recording the concrete time getting, if the time cycle arranging before the difference obtaining is less than, determine that the system load information of pre-stored server is not out of date.Otherwise, determine that the system load information of pre-stored server is out of date.Certainly, can also take alternate manner to judge that whether the system load information of pre-stored server is expired, the present embodiment is not done concrete restriction to this.In addition, the numerical value of time cycle can arrange as required, and the present embodiment is not done concrete restriction equally to this.In order to make the system load information of storage can reflect the truth of the system load information that server is current, the time cycle of setting is the smaller the better.
For example, the utilization rate of internal memory of take is example as system load information, the utilization rate of the internal memory getting at 10: 30 sub servers is 60%, the time cycle setting in advance is 5 minutes, if in the 10: 34 new pending requests of having assigned to, 10: 34 is 4 minutes with the difference of 10: 30, is less than 5 minutes time cycles that set in advance, and therefore now can judge that the system load information of pre-stored server is also not out of date.If in the 10: 36 new pending requests of having assigned to, 10: 36 is 6 minutes with the difference of 10: 30, is greater than 5 minutes time cycles that set in advance, and therefore, now can judge that the system load information of pre-stored server is out of date.
When the system load information of pre-stored server is expired, can again obtain according to above-mentioned first kind of way the system load information of server, and using the system load information getting as the current system load information of server.Further, after getting system load information, the system load information getting can also be updated in the storage medium of server, and upgrade the concrete time of this system load information of storage simultaneously, the present embodiment is not done concrete restriction to this.
The second situation, when the system load information of pre-stored server is not out of date, the system load information of the server of reading pre-stored, and using the system load information reading as the current system load information of server.
For the second situation, because the system load information of server has stability within the regular hour, for example, a system load information cpu busy percentage that is measured to server was 60% at 10: 35: 30, in 3 seconds after this time, if the cpu busy percentage of the server being measured to for 31 seconds for 35 minutes at 10 o'clock may be 60.1%, i.e. cpu busy percentage variation is less, in 3 seconds, has stability.Server is after getting current system load information, within the regular hour, the system load information before getting still has referential, therefore, whether the system load information that can judge pre-stored server is expired, when the system load information of pre-stored server is expired, the system load information getting before can illustrating has not had referential.When the system load information of pre-stored server is not out of date, the system load information of reading pre-stored, and using the system load information reading as the current system load information of server.
It should be noted that, owing to obtaining the current system load information of server at every turn, need to take regular hour and resource, therefore the system load information of utilizing server stability within a certain period of time, according to the above-mentioned second way, the current system load information of server is obtained, can shorten the time of obtaining the current system load information cost of server, and the resource that can save server, thereby improve the efficiency of obtaining the current system load information of server simultaneously.
202: the system load information that server is current is compared with the system load threshold value setting in advance;
Particularly, the concrete numerical value of system load threshold value can be set according to system specific performance or real needs, and the present embodiment is not done concrete restriction to this, include but not limited to realize in the following way:
Receiving system load threshold arranges order, according to system load threshold value setting command set storage system load threshold.The order of system load threshold value setting can adopt URL(Uniform Resource Locator, URL(uniform resource locator)) form, server receives after URL format command, the URL format command that parsing receives, obtain the system load threshold value of carrying in URL format command, and the system load threshold value getting is stored.Wherein, the order of system load threshold value setting can also adopt other form, and as text message format etc., the present embodiment is not done concrete restriction to this.
It should be noted that, if system load information comprises much information,, when corresponding system load threshold value is set, need to corresponding system load threshold value be set for every kind of system load information.In addition, according to the order of system load threshold value setting, carrying out after the setting of system load threshold value for the first time, the method that the present embodiment provides is also supported in subsequent operation receiving system load threshold again order is set, again system load threshold value is set according to the system load threshold value setting order again receiving, reach the object that system load threshold value is upgraded.The number of times that order is set about receiving system load threshold, the present embodiment is not specifically limited.
Further, no matter receive system load threshold value setting order several times, after receiving the order of system load threshold value setting at every turn, can also judge that the order of system load threshold value setting is legal, when the order of judgement system load threshold value setting is legal, according to system load threshold value setting command set storage system load threshold.Wherein, the IP(Internet Protocol of the equipment of order can be set according to transmitting system load threshold, Internet protocol) address judges that whether the order of system load threshold value setting is legal, or can also whether correctly judge that whether the order of system load threshold value setting is legal according to the form of system load threshold value setting order.
Wherein, the IP address that the equipment of order is set according to transmitting system load threshold judges when whether the order of system load threshold value setting is legal, can on server, store in advance the blacklist of malice IP address, when getting the system load threshold value setting order of certain equipment transmission, can judge that the IP address of this equipment is whether in the blacklist of malice IP address, if the IP address of this equipment in blacklist, can determine that the system load threshold value setting order of this equipment transmission is illegal.Or, can also on server, store in advance the white list of legitimate ip address, if the IP address of this equipment not in white list, can determine that the system load threshold value setting order of this equipment transmission is illegal.Further, the IP address that server obtains legal or malice can obtain according to historical record statistics, the present embodiment does not obtain mode legal or malice IP address to server and does concrete restriction, also to the IP address of the equipment of order is set according to transmitting system load threshold, does not judge that the whether legal mode of system load threshold value setting order does concrete restriction.
203: according to comparison result, determine whether server transships;
Particularly, comparison result can include but not limited to following two kinds:
The first: the current system load information of server is greater than the system load threshold value setting in advance;
The second: the current system load information of server is less than or equal to the system load threshold value setting in advance.
While determining according to comparison result whether server transships, if comparison result is above-mentioned the first, can determine server overload, if comparison result is above-mentioned the second, can determine that server does not transship.
For example, the system load threshold value setting in advance is cpu busy percentage 90%, memory usage 80%.When getting the current system load information of server, it is cpu busy percentage 92%, during memory usage 87%, after the current system load information of server is compared with the system load threshold value setting in advance, comparison result is that the current system load information of server is greater than the system load threshold value setting in advance, and now can determine that server transships.
It should be noted that, if the current system load information of server comprises much information, set in advance corresponding multiple systems load threshold, when the current system load information of server is compared with the system load threshold value setting in advance, if having a comparison result is situation about being greater than, determine server overload.That is to say, in the situation that every current system load information of server is all less than corresponding system load threshold value, just determine that server does not transship.
204: if determine server overload, obtain refusal in Preset Time section and process the number of times of asking;
Particularly, determine after server overload, can refuse to process to pending request.As a kind of optimal way, for fear of all requests in the short time, be all rejected, in order to guarantee that the resource of server obtains larger utilization, can obtain the number of times of refusing to process request in Preset Time section, further to judge the processing mode to pending request by subsequent step simultaneously.
205: the number of times of processing request according to the refusal getting determines whether the pending request of refusal processing;
Particularly, getting refusal in Preset Time section processes after the number of times of request, whenever receive pending request time, can judge whether the number of times of the processing request of refusal before this reaches the number of times of refusal request in Preset Time section, if reach, accept this time pending request, and then follow-up it is processed.Otherwise, can select at random refusal or accept this time pending request.Certainly, can also get the number of times of accepting to process request in Preset Time section, when arriving pending request new, whether the number of times that can judge the processing request of accepting before this reaches the number of times accepting request in Preset Time section, if reach, this time pending request of refusal, and then follow-up it is processed.Otherwise, can select at random refusal or accept this time pending request.The present embodiment does not determine whether to process the number of times of request according to the refusal getting that the mode of the pending request of refusal processing limits, certainly, can also adopt other modes to determine whether the pending request of refusal processing, the present embodiment is not done concrete restriction equally to this.
206: if determine the pending request of refusal processing, refuse pending request to process.
Particularly, if determine after the pending request of refusal, refuse pending request to process, can also send refusal response to the equipment that sends pending request, so that opposite equip. is known the result of this request simultaneously.About sending the mode of refusal response, the present embodiment is not done concrete restriction to this.
The method that the present embodiment provides; because the system load information of server has determinacy; thereby system load threshold value can reflect the truth whether server transships; therefore; after the current system load information of server is compared with the system load threshold value setting in advance, according to comparison result, can determine accurately whether server transships, thereby when determining server overload; by refusal, pending request is processed, realized server is carried out to better overload protection.
