Fig. 2 is a kind of flow chart of resource access method based on zookeeper shown according to an exemplary embodiment.
As shown in Fig. 2, the method includes the following steps.
Step 201, when receiving acquisition request of the destination client for target resource, resource accesses system and obtains in advance
If target resource target access path.
In the embodiment of the present invention, resource access system can detecte whether receive destination client for target resource
Acquisition request, that is, for the access request of target resource, if received, the target of available preset target resource
Access path.Wherein, destination client wants access to target resource, that is, wants the corresponding node of request target resource
It locks (i.e. distributed lock).
Step 202, resource access system searches target access path with the presence or absence of target section in zookeeper cluster
Point；If there is destination node, triggering executes step 203；If there is no the destination node, terminate this process.
In the embodiment of the present invention, whether resource access system can search target access path in zookeeper cluster
There are destination node, lookup result is obtained, and destination node is judged whether there is according to the lookup result；If there is the target
Node, triggering execute step 203；If there is no the destination node, optionally, target can be created in the target access path
Node, and the interim child node of target is created under destination node.
It is understood that if resource access system is judged to may indicate that target visitor there is no the destination node
Family end requests the node of the target resource to be locked earliest, therefore, can create in zookeeper cluster and be named with target resource identifier
Destination node, and create under the destination node the interim child node of the corresponding target of acquisition request of the destination client；Its
In, which is lasting node.
Step 203, resource access system creates the interim child node of target under destination node, and by the spy of destination client
It levies data and the interim child node of target is written, to determine that destination client gets node lock.
As an alternative embodiment, after creating the interim child node of target under destination node, and by target
Before the characteristic write-in interim child node of target of client, resource access system also executes following steps:
Detect whether to receive the acquisition request for node lock that other clients in addition to destination client are sent；
If so, obtaining the sequence number of the interim child node of target；
Judge whether sequence number is minimum value in sequence number list；Wherein, sequence number list is by target section
The sequence number of all interim child nodes under point is constituted；
If sequence number is the minimum value in sequence number list, target is written in the characteristic by client of execution
Interim child node.
In the embodiment of the present invention, in zookeeper cluster, the sequence number numerical value reckling for defaulting child node can be obtained
Node lock, therefore, resource accesses the sequence number of the interim child node of the available target of system, by judging that sequence number is
The no minimum value in sequence number list is locked to determine whether destination client can obtain the corresponding node of the destination node.
Further, as another optional embodiment, if sequence number be not in sequence number list most
Following steps can also be performed in small value, above-mentioned resource access system:
Event monitoring is arranged to destination node, and obtains corresponding monitored data；
Match the anomalous event strategy of monitored data and default setting；
If successful match generates anomalous event；
When the node data of anomalous event instruction destination node changes, alert notification is sent to destination client；
Wherein, node data changes including node creation, knot removal, node data modification and child node change.
In the embodiment of the present invention, resource access system can preset the resolution policy that a variety of anomalous events are arranged, i.e., extremely
Event Policies, wherein anomalous event may include the node data of destination node change this event therefore can be right
Event monitoring is arranged in destination node, and when the variation of data or structure occurs for node, triggering zookeeper notifies target customer
End；Wherein, specifically, node data change specifically can be node creation, knot removal, node data modify and
Child node change etc..For example, the transient node of its correspondence establishment can disappear immediately when any client disconnects every time, thus
Clustered node exception can be listened to.In addition, other clients in addition to destination client can also be arranged destination node
Event monitoring, and when monitoring anomalous event, other clients of event monitoring can be also provided with for destination node to other
End sends alert notification.As it can be seen that the notice of message can be realized by asynchronous call using this method, that is to say, that message
Publisher only needs to send alert notification, and recipient's (client) of message does not need cyclic query alert notification either with or without reaching
It arrives, when there is alert notification arrival, the recipient of zookeeper meeting active warning message；Reduce the recipient of message in this way
The wasting of resources of (client).
Step 204, resource accesses system and locks to destination client return node.
In the embodiment of the present invention, resource accesses system and locks to destination client return node, i.e., destination client is locked,
The accessible target resource in destination client optionally access target resource and completes corresponding Business Stream in destination client
After journey, the corresponding interim child node of target can be deleted, at this point, node lock is released.
As an alternative embodiment, after step 204, following steps can also be performed in resource access system:
Obtain the heartbeat link information between the Distributed Services equipment corresponding with target resource of destination client；
Judge whether destination client terminates the access to target resource according to heartbeat link information；
If destination client terminates the access to target resource, the interim child node of delete target.
As it can be seen that implementing the resource access method based on zookeeper described in Fig. 2, can exist in destination client
When to the requirements for access of target resource, feeding back the access to zookeeper cluster in a manner of creating the interim child node of target is needed
It asks, and the interim child node of target is written into the characteristic of destination client, to determine that destination client gets node lock.Face
Shi Jiedian has the characteristics that deletable compared to lasting node, therefore this programme can reduce the occupancy of memory space, to drop
Influence of the low resource access to the performance of zookeeper；In addition, can realize message by asynchronous call using this method
Notice, that is to say, that the publisher of message only needs to send alert notification, and recipient's (client) of message does not need to follow
Ring inquires alert notification either with or without reaching, and when there is alert notification arrival, zookeeper understands the recipient of active warning message；
Reduce the wasting of resources of recipient's (client) of message in this way.
In the embodiment of the present invention, in target customer between destination client and the Distributed Services equipment for issuing target resource
End keeps certain connection when accessing to target resource, and whether judges other side by way of regularly sending heartbeat packet
It disconnects；If not receiving heartbeat packet in certain time, judgement is already off with the connection of other side, therefore can stop
Request service is provided for other side or requests to service to other side.Therefore, resource access system can be connected by obtaining above-mentioned heartbeat
Information is connect to judge whether the connection between destination client and distributed server is interrupted, and then may determine that destination client
Whether access to target resource is terminated, if destination client terminates the access to target resource, the interim son section of delete target
Point.Zookeeper safeguards node (i.e. znode), wherein node is divided into transient node and lasting node, and node
Type is determining in creation and cannot modify again later.The difference of both nodes is: in the client of creation transient node
When holding conversation end, zookeeper can delete the transient node (the interim child node of such as target)；In contrast, lasting node
(such as destination node) independent of client session, only when client clearly will delete the lasting node, lasting node is
It can be deleted；And of short duration node cannot have child node.
In the present solution, destination client in access target resource, needs to know clustered machine list, by with cluster
In a certain machine establish TCP (Transmission Control Protocol, transmission control protocol) connection use clothes
Business, destination client can be used this TCP chain and fetch transmission request, obtain result, obtain monitoring event and send heartbeat
Packet.So monitoring can be arranged for each machine (distributed server) in cluster, the load of its node is monitored；Work as reception
When acquisition request (access request) for target resource sent to destination client, if the access of destination node is negative at this time
Lotus is higher than default load threshold value, and the access request of destination client can be guided into the minimum machine of load (other distribution clothes
Business device) in.It is further alternative, determine that the load of a certain machine in cluster is that minimum mode may is that detection is each
The received access request (resource acquisition request) of platform machine institute, including read and write.The least machine of access request is determined
For the machine that load is minimum, and the access request of destination client is guided into the minimum machine of the load.
As an alternative embodiment, resource access system can use zookeeper same node point and can store
Same services are safeguarded for the child node function of sequence.For example, target resource can be a certain service, therefore destination node can be with
It is stored with the related data (such as servicing online related configuration data) of the service, meanwhile, in zookeeper, there is also a certain
Two nodes can store the offline related configuration data of the service and the third node of other related services, then can be with
Destination node and second node, third node etc. are stored as the child node of sequence to facilitate user maintenance same services.
Fig. 3 is a kind of process of the resource access method based on zookeeper shown according to another exemplary embodiment
Figure.As shown in figure 3, being somebody's turn to do the resource access method based on zookeeper may comprise steps of:
Step 301, when receiving acquisition request of the destination client for target resource, resource accesses system and records mesh
Mark the accumulative request number of times for the acquisition request for target resource that client is sent.
Step 302, resource access system judges whether accumulative request number of times is greater than preset request threshold value；If accumulative ask
Number is asked to be greater than preset request threshold value, triggering executes step 303；If accumulative request number of times is not more than preset request threshold
Value, triggering execute step 304.
Step 303, acquisition request of the resource access system to destination client for target resource executes shielding processing.
In the embodiment of the present invention, the mode of shielding processing can be refuses destination client for target in preset duration
Any acquisition request of resource；Further, resource access system can also carry out blacklist label to destination client, so that
It destination client can not access target resource；Or resource access system can be directed to the acquisition of target resource to destination client
Request carries out delay disposal, and the embodiment of the present invention is without limitation.
In the embodiment of the present invention, if destination client is excessively frequent to the number of the acquisition request of target resource, it is easy
It causes target resource to be occupied for a long time by destination client, causes other clients in addition to destination client that can not access mesh
Resource is marked, and then causes the pressure of zookeeper cluster excessive, the utilization rate of target resource reduces, therefore, by target visitor
To destination client for target resource when family end is greater than preset request threshold value for the accumulative request number of times of target resource
Acquisition request executes shielding processing, realizes the reasonable distribution of shared resource, while also reducing the processing of zookeeper cluster
Pressure.
As an alternative embodiment, resource accesses the acquisition request that system is directed to target resource to destination client
Shielding processing is executed, may include:
Refuse the acquisition request that destination client is directed to target resource in preset duration, and will tire out after preset duration
Request number of times is counted to reset.
In the embodiment of the present invention, further, resource accesses system after resetting accumulative request number of times, can be again
The new acquisition request that destination client is directed to target resource is received, and step 304 is executed according to the new acquisition request triggering.
Step 304, resource access system obtains the target access path of preset target resource.
Wherein, being somebody's turn to do the resource access method based on zookeeper further includes step 305~307, for step 305~307
Description, please refer to the detailed description that step 202~204 are directed in above-described embodiment one, the embodiment of the present invention repeats no more.
As it can be seen that the resource access method based on zookeeper described in implementing Fig. 3, can exist in destination client
When to the requirements for access of target resource, feeding back the access to zookeeper cluster in a manner of creating the interim child node of target is needed
It asks, and the interim child node of target is written into the characteristic of destination client, to determine that destination client gets node lock.Face
Shi Jiedian has the characteristics that deletable compared to lasting node, therefore this programme can reduce the occupancy of memory space, to drop
Influence of the low resource access to the performance of zookeeper；And message can be realized by asynchronous call using this method
Notice, that is to say, that the publisher of message only needs to send alert notification, and recipient's (client) of message does not need to follow
