Abstract
The invention discloses a fault-tolerance based distributed service registration and query method. The registration method comprises the steps that 1, the registration process of super nodes is carried out, the registrations of the analyzed data are completed in the super nodes by the system, and kept in a local disk; 2, the registration process of redundant nodes is carried out, the service registration information is sent to distributed nodes by the system through an adjustment unit, and kept in the disk of a corresponding node. The query method comprises the steps that 1, the query process of the super nodes is carried out, the system concurrent access is relatively low, and the query results are sent back to the user through the super nodes; 2, the query process of the distributed nodes is carried out, the system concurrent access is high, the query requests are sent to the distributed nodes, and query tasks are executed in parallel by each node, and finally the results are returned to the user. The service system built based on the registration method and the query method overcomes the shortcoming existed in centralized framework, the high availability of query service and the rapid and high efficiency of queries are achieved.
Description
Technical field
The present invention relates to Web service field, and in particular to a kind of based on fault-tolerant Distributed Services registration and querying method.
Background technology
Web service quantity on the Internet constantly increases, and set of service is constantly converged, how quick from extensive service
Accurately orienting destination service becomes the vital task that service-oriented frame system is realized, is also key urgently to be resolved hurrily
Problem.The Web service Accreditation System of traditional centralized architecture uses a kind of means of monopolization, and all of Service Source is all
Concentrate on a central server.The advantage of this network structure is：Safeguard that simple, real-time is high so as to shared resource
Search and update very convenient.But the drawbacks of this centralized configuration there is also obvious：Reliability and safety are relatively low, central authorities' clothes
Business device Single Point of Faliure will cause all Service Sources unavailable；Maintenance cost is high, with the increase of Service Source scale, to central authorities
Server is safeguarded and the complexity that updated and cost will be sharply increased.
The content of the invention
In view of the drawbacks of centralized architecture is present, of the invention to realize that Service Source is stored and superfluous by distributed network architecture
Remaining backup, realizes distributed organization and the management of service.System is parsed to magnanimity initial data with reference to distributed computing technology, divided
Cloth is stored and redundancy backup, using distributed enquiring method inquiry data rapidly and efficiently in query script, and by
Zookeeper frameworks and Netty frameworks ensure respectively the high efficiency of the high availability and inquiry for inquiring about service.
Based on fault-tolerant Distributed Services registration, inquiry and Web service framework construction method, comprise the steps：
（1）Initial data is obtained from the Internet（Web service describes document）, carried out using Membrane SOA Model frameworks
Parsing.
（2）Using Distributed Services register method, system will parse the data forwarding for generating to system call unit.
（3）System call unit information on services is stored into into respectively super node and cluster in distributed node；
（4）Using Distributed Services querying method, system sends inquiry request to each node.
（5）Query Result is inquired about and returned to each node according to request execution.
The step（2）In Distributed Services register method at least comprise the steps：
（1）Super node registration process is performed, the data after parsing are completed registration by system in super node, and are persisted to this
Local disk.
（2）Redundant node registration process is performed, system sends service registration information to distributed section via scheduling unit
Point, and it is persisted to corresponding node disk.
The step（4）Middle Distributed Services querying method at least comprises the steps：
（1）Super node query script is performed, system concurrency visit capacity is relatively low, then Query Result is back to use by super node
Family.
（2）Distributed node query script is performed, system concurrency visit capacity is high, then inquiry request is sent to distributed section
Point, each nodal parallel performs query task, finally result is back to into user.
Description of the drawings
Fig. 1 is the FB(flow block) of the present invention.
Specific embodiment
As shown in figure 1, based on fault-tolerant Distributed Services registration and inquiry, illustrate the distributed registry of whole system with
Query script, data resolution module is parsed to initial data, and for Distributed Services Registering modules effectively original data are provided.
Distributed registry module is stored into each node in cluster to the data distribution formula through parsing；Data backup module will be registered
Information on services backup on distributed node, improve the fault-tolerance of system；Distributed query module is obtained by page request
The inquiry request at family is taken, inquiry request is distributed to each node in cluster by system, after node is asked, inquiry service
Just inquire about local data base and Query Result is back to into system, system merges sequence to the data that each node is returned, most
After return to user.
What Distributed Services were registered concretely comprises the following steps：
（1）User signs in super node by browser, submits service registration request to.
（2）Super node uses Membrane SOA Model Analysis on Framework service registration requests, and will take in the node
Business information is persisted to MySQL database.
（3）Super node is to ZooKeeper cluster application backup nodes address.
（4）Super node is dispatched using Netty communications frameworks and is forwarded to backup node with distribution registration request.
（5）Backup node uses Membrane SOA Model Analysis on Framework service registration requests, and will take in the node
Business information is persisted to MySQL database.
What Distributed Services were inquired about concretely comprises the following steps：
（1）User signs in super node by browser, submits service-seeking request to.
（2）When concurrently visit capacity is relatively low, super node parsing inquiry request, and inquiry is completed in the node, will inquiry knot
Fruit is back to user.
（3）When concurrently visit capacity is higher, the preferential custom system of order will be back to Query Result by super node
User；The service-seeking request that follow-up user submits to, then be distributed to distributed node by system, and Query Result is by being distributed
User is inquired about and be back to each nodal parallel of formula.
Web service system is built according to the registration of above-mentioned Distributed Services and querying method, is comprised the steps：
（1）Initial data is obtained from the Internet, is parsed using Membrane SOA Model frameworks.
（2）Using Distributed Services register method by the data forwarding after parsing to system call unit.
（3）Information on services is stored into respectively system call unit super node and distributed each node.
（4）Distribute inquiry request to each node using Distributed Services querying method system.
（5）Each node performs inquiry and returning result according to request.
（6）System is ranked up to the result that each node is returned.
The present invention makes full use of the high efficiency of distributed computing technology by the brand-new service registry of structure and inquiry system, will
The registration of information on services is combined together with inquiry and completes core business, and system is won using Hong Kong Chinese University Zibin Zheng
, used as initial data, data resolution module is carried out to initial data for scholar's collection and on the internet disclosed Web service data collection
Parsing, service register module is separately stored on the super node of cluster and each distributed node to the data after parsing, starts
Inquiry service processing inquiry request on each node, finally realizes the rapidly and efficiently property of inquiry in inquiry system.
