He is integrated with the electronic equipment of Nginx functions of the equipments, is not restricted.At this
In bright embodiment, will come the present invention as a example by described client data processing device is for Nginx equipment
Data download method in embodiment is described in detail.
As a example by the Nginx framework described in Fig. 1, server A, server B and server C are respectively
Three web servers, it is assumed that the server address of its correspondence is respectively as follows: server A: 192.168.1.17；
Server B: 192.168.1.18；Server C:192.168.1.19.Server A, server B and clothes
In business device C, storage has all data of client, e.g., each application data of client, client
The running state data etc. of end, thus, when client needs to obtain certain data, Nginx equipment can
Obtain with any one from three servers.In embodiments of the present invention, need with client
The first data obtained are that health watch data instance illustrates.
When method in using the embodiment of the present invention downloads data, step 101 is first carried out, it may be assumed that visitor
Family end data processing equipment determines the N number of server being in normal condition from M server, wherein,
M is the integer more than or equal to 1, and N is the integer less than or equal to M.
In embodiments of the present invention, refer to Fig. 3, the specific implementation of step 101 is as follows:
1011: described client data processing device each server in described M server sends to be tested
Card request；
1012: described client data processing device receives M the sound sent by described M server
Answer information；
1013: based on described M response message, described client data processing device is from described M
Server is determined the N number of server being in normal condition.
In specific implementation process, continue to use above-mentioned example, Nginx equipment need to detect in real time server A,
Server B and the duty of server C, it may be judged whether have a server fail, thus Nginx
Equipment needs to send checking request to three servers respectively.Described checking request can be specifically that http please
Ask, it is of course also possible to be other kinds of request, be not restricted.
By Nginx equipment as a example by three servers send http request, Nginx can use broadcaster
Formula sends, it is also possible to according to the address of each server, sends http request to three servers respectively.
In order to save the energy consumption of Nginx equipment, a predetermined interval can be preset, such as 10s or 20s etc.,
Thus Nginx equipment can send checking request with described predetermined interval to three servers, so, both
Can guarantee that the duty obtaining each server in real time, also can at utmost save the energy of Nginx equipment
Consumption, certainly, described predetermined interval duration can be determined according to actually used situation, art technology
Personnel can also use other mode to obtain the duty of each server in real time.
After three servers are respectively received the http request that Nginx equipment sends, it will to Nginx
Equipment feedback response information, includes the answer code to http request in described response message.Work as Nginx
After equipment receives the response message that three servers send, just extract the answer code in described response message,
Rule of judgment is prestored, e.g., when answer code is 200 in Nginx equipment, it is determined that corresponding
Server is in normal condition, otherwise, it determines server exception or break down.If Nginx equipment obtains
The answer code taken in the response message that three servers send is respectively as follows: server A: 201；Server B:
200；Server C:200, due to 201 ≠ 200, is working as so that it is determined that go out server B and server C
Being in normal condition in the front moment, server A occurs abnormal.
Owing to the duty of each server may constantly change, therefore, Nginx equipment needs
Will according to subsequent time by the answer code real-time update of each server feedback to each server contention states
Judged result.
Certainly, the duty of server can also the most once be judged by Nginx equipment, e.g., when
When server is connected in Nginx equipment composition server system, just send checking request to server,
After obtaining the result, just described the result is stored in Nginx equipment, to characterize this service
The duty of device, is not restricted.
After having performed step 101, the method in the embodiment of the present invention just performs step 102, it may be assumed that
Described client data processing device obtains the request of data for obtaining the first data that client sends.
In specific implementation process, when client needs to obtain its health watch data, Nginx equipment will
URL (URL) information sent by client can be received, in described URL information
The information comprised points out the filename of the data content of client needs, and then, Nginx equipment extracts URL
For characterizing the part of filename in information, determine that the data of client acquisition request are health watch data.
Certainly, inevitably there is following situation: Nginx equipment is determining the work of each server
During state, receiving the health watch data request information sent by client, now, Nginx equipment is also
After needing first to determine the duty of each server, then the health watch request of data that client is sent
Information processes, so that it is guaranteed that Nginx equipment can obtain from the server being in normal condition every time
Fetch data, improve the hit rate of Nginx equipment.
After having performed step 102, the method in the embodiment of the present invention just performs step 103, it may be assumed that
Based on described request of data, described client data processing device determines from described N number of server
One server.
In specific implementation process, the specific implementation of step 103 has multiple, in the embodiment of the present invention
In mainly illustrate with the following two kinds situation:
First kind of way, step 103 includes:
Described client data processing device obtains the cryptographic Hash of described request of data；
Based on described cryptographic Hash, described client data processing device determine from described N number of server with
The first server that described cryptographic Hash is corresponding.
In specific implementation process, continue to use above-mentioned example, when Nginx equipment determines that client request obtains
After the data taken are health watch data, in order to improve the access hit rate of Nginx equipment, Nginx further
Equipment just can carry out the process of cryptographic Hash calculating to the URL information that client sends.Cryptographic Hash is one section
The numeric representation form that data are unique and the compactest, is that the data of the content according to file are transported by logic
The resin obtained, the cryptographic Hash that different files obtains is different, even if file content only one of which
Letter or the difference of character, corresponding cryptographic Hash is different from, and therefore, it can be tested by cryptographic Hash
Demonstrate,prove multiple message the most identical.Typical hash algorithm includes MD2, MD4, MD5 and SHA-1 etc.,
Repeat no more in embodiments of the present invention.
As a example by the cryptographic Hash of the URL information of client transmission is 10, go to a party when Nginx equipment calculates
After the cryptographic Hash of the URL information that family end sends, can be according to the IP address of server and URL information
Cryptographic Hash calculate a mark, thus be defined as server the highest for mark obtaining health watch data
Server.As, Nginx equipment determine be in the server of normal condition be respectively server B and
Server C, thus calculate dividing of server B according to the IP value of server B and the cryptographic Hash of URL
Number is 100, and it is 80 that the IP value of server C and the cryptographic Hash of URL calculate the mark of server B,
And then determine that server B is first server.
Correspondingly, described first number is obtained at described client data processing device from described first server
According to, and described first data are sent after described client, described method also includes:
It is corresponding with the first of described first server that described client data processing device sets up described cryptographic Hash
Relation, and described first corresponding relation is stored in described client data processing device.
In specific implementation process, continue to use above-mentioned example, when Nginx equipment is determined from server B
Obtain after health watch data, Nginx equipment just set up the cryptographic Hash of the health watch solicited message of client with
The corresponding relation of server address, such as: cryptographic Hash 10:192.168.1.18, is stored in Nginx equipment
In memorizer.So, when Nginx equipment detects the solicited message obtaining same cryptographic Hash next time,
Just directly obtain from server B, thus decrease the amount of calculation of Nginx equipment and improve data and obtain
The speed taken.
The second way, step 103 includes:
Described client data processing device obtains a preset rules；
Described client data processing device determines from described N number of server and meets described preset rules
First server.
In specific implementation process, continue to use above-mentioned example, when Nginx equipment determines that client request obtains
After the data taken are health watch data, just determine acquisition according to the preset rules being stored in Nginx equipment
The first server of health watch data.As, when described preset rules is random, then Nginx equipment just from
Server B and server C randomly choose a server as first server, as determined server
B is first server；Or, described preset rules is: determine that current time loads little server and is
First server.At this moment, Nginx equipment needs to obtain server B and the present load amount of server C,
If the load capacity of server B is 20, the load capacity of server C is 30, it is determined that server B is
One server；Or, described preset rules is: first server definite sequence really is A > B > C.Now,
Owing to server A is in abnormality, then the order automatically according to default settings determines that server B is
First server.
Certainly, those skilled in the art can also be according to other rule of actually used requirements set, at this
Inventive embodiments is not restricted.
After having performed step 103, the method in the embodiment of the present invention just performs step 104, it may be assumed that
Described client data processing device obtains described first data from described first server, and by described the
One data send to described client.
In specific implementation process, continue to use above-mentioned example, when Nginx equipment determines that server B is
After one server, just the URL information that client sends is sent to server B, server B obtain
The health watch data corresponding with client, and by described health watch data feedback to Nginx equipment, and lead to
Cross Nginx equipment to send health watch data to client, complete client under health watch data
Load process.
