The business loses too many value.
S411, when each business for getting speed more than each business speed predetermined threshold value when, generation the 3rd
Control signal；
S412, the speed that each business is limited based on the 3rd control signal；
S413, the speed for obtaining each user's access service；
Whether the speed of each user's access service that S414, judgement get is more than the speed of each user's access service
Predetermined threshold value；
Determine whether whether the speed of each the user's access service for getting is more than the speed of each user's access service
The predetermined threshold value CID_API_rate of rate.
S415, speed the presetting more than the speed of each user's access service when each the user's access service for getting
During threshold value, the 4th control signal is generated；
S416, the speed that each user's access service is limited based on the 4th control signal.
In sum, in the above-described embodiments, limitation, the Neng Goushi of the total speed to accessing news client can be realized
Limitation existing to the access rate of each IP, can realize to the rate limit of each business and can realize to each user
Access the limitation of the speed of API.
The present invention can also realize that dynamic sets rate parameter, and the initialization of parameter TOTAL_rate and API_rate is
According to the result for carrying out pressure test to whole system and single business, the two values will not typically change, if system or industry
Business upgrading, then can be modified by web platforms, system and business is rationally provided service.
The initialization of parameter IP_rate and CID_API_rate is to set based on experience value, and the value of initialization is not necessarily closed
Reason can otherwise be lost in the user of part, it is necessary to dynamically adjusted according to the situation that each IP and user access API.Dynamic
Arrange parameter IP_rate, CID_API_rate step is as shown in figure 5, comprise the following steps：
S501, at interval of n minutes, obtain each procotol and each user respectively from Nginx servers and access industry
The historical data of business；
Web platforms obtained the historical data of IP and CID_API respectively every n minutes from Redis servers.
S502, the historical data to time interval [now_ts-interval, now_ts] are fitted, and obtain being fitted letter
Number f (x), judges slope θs of the f (x) at interval [now_ts-interval, now_ts], if θ is less than θmin, then stop, if otherwise
Into S503：
Historical data to time interval [now_ts-interval, now_ts] is fitted, and obtains fitting function f
X (), judges slope θs of the f (x) at interval [now_ts-interval, now_ts], if θ is less than θmin, then stop, otherwise turning step
Rapid S503.
S503, calculatingValue, i.e., in interval [now_ts-interval, now_ts]
Value, ifIndustry is accessed more than the access rate predetermined threshold value of each procotol or each user
The predetermined threshold value of the speed of business, HTTP is sent by the web page platform based on Nginx servers and script
Request sets the predetermined threshold value of the speed of the access rate predetermined threshold value or each user's access service of each procotol.
CalculateValue, i.e., the intermediate value of interval [now_ts-interval, now_ts], ifMore than IP_rate, the value that http request sets IP_rate is sent by web platforms, it is right
Similarly, the setting of these parameters can come into force CID_API_rate in real time, without restarting or reloading Nginx server clusters.
As shown in fig. 6, being a kind of real-time flux control system embodiment 1 based on Nginx servers disclosed by the invention
Structural representation, the system includes：
Real-time traffic monitoring module 601 based on Nginx servers, total speed of news client is accessed for obtaining；
Whether dynamic realtime flow control module 602, total speed of the access news client for judging to get is big
In the total speed predetermined threshold value for accessing news client；When total speed of the access news client for getting is more than access news
During total speed predetermined threshold value of client, the first control signal is generated；News client is accessed based on the limitation of the first control signal
Total speed.
The Nginx server sets for being forwarded to news client of the load-balancing device that the request of client passes through company
Group.Prevent normal discharge too high or malicious attack causes the flow of whole news client excessive, influence business, cause unnecessary
Loss.The present embodiment has carried out the limitation of flow, the access news client that judgement gets on each Nginx server
Whether total speed at end is more than the total speed predetermined threshold value total_rate for accessing news client.
If the speed of the request has exceeded default threshold value total_rate, generate the first control signal is carried out to request
Limitation
The total speed for accessing news client is limited by the first control signal, the request rate of arrival rear end is maintained at
In the range of [0, total_rate*N], wherein N is the number of Nginx servers.
In sum, in the above-described embodiments, when needing to monitor flow in real time, Nginx servers first
Real-time traffic monitoring module obtain the total speed for accessing news client, then judge the access news client for getting
Whether total speed is total when the access news client for judging to get more than the total speed predetermined threshold value for accessing news client
When speed is more than the total speed predetermined threshold value for accessing news client, the first control signal is generated, be finally based on the first control letter
