Hold.
Describe the cluster management device 40 according to the present embodiment and its treatment in detail with reference to Fig. 3 and Fig. 4 further below.
Cluster management device 40 as shown in Figure 4 includes reception and memory module 41, sending module 42, monitors module 43, judges to update mould
Block 44.It should be noted that the annexation being not limited to shown in Fig. 4, can be connected with each other between each module.
The following detailed description of each step that cluster management is carried out according to the cluster management device 40 of the present embodiment.
Step S310, is received and memory module 41 is received and stored from each industry in the cluster that cluster management device is managed
The respective network access address of each service server 30 that business server 30 is sent.For example, each service server 30 is to cluster pipe
Reason device 40 is registered（Send）The IP ground for providing network service to service customer end 10 (abbreviation client 10) of its own
Location and port numbers (port), cluster management device 40 receive and store the IP (Internet that each service server 30 is sent
Protocol) address and port numbers.These network access addresses come can be received to store as network access address list.More
Preferably, can be cooperateed with using Zookeeper technologies, the IP address of each business service port 30 and port numbers can respectively be deposited
Storage specifically, each network access address is divided as a back end (znode) in the tree-shaped virtual file of Zookeeper
Do not store into the tree-shaped virtual file of Zookeeper one it is default for representing the cluster that cluster management device 40 is managed
Virtual root node under each back end in, be designated as "/A " (referring to Fig. 7).Because Zookeeper allows multiple to be distributed in not
Cooperated based on shared, similar standard file system a tree-shaped Virtual File System with the process on server.
Each back end in Virtual File System is referred to a znode, and each znode can be data correlation to itself
Or its child node, therefore, when being cooperateed with using Zookeeper technologies, it is possible to reduce the program development of technical staff
Amount, preferably avoids data access conflict, can preferably solve Data Concurrent modification, the data being likely to occur under distributed environment
The problem of Backup and Restore and data consistency.
However, for purposes of illustration only, mainly being illustrated by taking network access address list as an example below.
Step S320, sending module 42 sends each business service by receiving and memory module 41 is stored to client 10
The network access address of device 30.Sending module 42 can push each business of stored at least one and take to each client 10 on one's own initiative
The network access address of business device 30, it is preferable that sending module 42 can be according to the net for obtaining service server of client 10
The request of network reference address to 10 sends the network access address of each service server 30 stored up.
Step S330, alternatively, monitors the running state information of the monitoring service server 30 of module 43.Specifically, can supervise
Listen with receive and network access address that memory module 41 is stored corresponding to service server 30 running state information.Fortune
Whether row status information is included on the available information of service server.Usually, if listening to certain service server 30
Running state information, then can determine whether as the service server 30 is available, that is, service can be provided to service customer end 10.Example
Such as, cluster management device 40 periodically can receive the information on running status from service server 30（Below the also abbreviation heart
Hop-information）.By monitoring the snoop-operations of module 43, each business clothes in service server cluster can be in real time known as far as possible
The change of the network access address of business device.
Additionally, the running state information that reception and memory module 43 are monitored may also include on service server certainly
The information of body performance and/or loading condition, so, client 10 can from cluster management device 40 obtain these performances and/or
The information of loading condition, and then select to be accessed 30 based on the information of these performances and/or loading condition.So, can be with
Load balance is better achieved.After step S330, into step S340.
Step S340, judges that update module 44 judges that the reception and memory module 41 are deposited based on the running state information
Whether the service server corresponding to the network access address of storage can provide service and according to judgement knot to the service customer end
Fruit updates stored network access address.If more specifically, monitoring less than a certain network access in each network access address
During the information that the corresponding service server 30 in address is sent, then it is judged as that the service server 30 is unavailable.Then, judge to update
Module 44 can update stored network access address according to judged result.The place of the network access address that the renewal is stored
Managing to be：The network access that network access address corresponding with disabled service server 30 is stored from step S310
In address list delete, or can in network access address list with the corresponding network access of disabled service server 30
Address is marked.Additionally, also can be by monitoring the machine of delaying of each service server 30, overburden, fault warning, restarting alarm etc.
Running status come obtain each service server 30 respectively whether available information.Subsequently into step S350.
Step S350, sending module 42 to service customer end 10 send by it is described judge update module be judged as can be should
Service customer end provides the network access address of service.If monitoring the heartbeat message less than a certain service server 30, can be
In S340 by the network access address of the service server 30 delete or be marked as it is impossible, so as to client 10
When sending network access address, the address of the service server 30 is not retransmited, but only send and be judged update module 44 and sentence
Break as the network access address of service can be provided for service customer end.The network that so each client 10 can be stored to it is visited
Ask that address list is updated.It should be noted that sending module 42 can use asynchronous notifications mechanism, make service customer end saturating
Bright use service server.More specifically, after judging that update module 44 is updated operation, sending module 42 can be immediately
The network access address for being stored after updating is sent to client 10, but it is also possible to which a certain moment afterwards retransmits, because
Even if not send immediately, client 10 is due to having saved network access address list therefore still can normally access industry
Business.
It should be noted that the order between above step S320 and step S330 and S340 can be arbitrary.
Fig. 6 shows the structural representation of the client 10 according to the present embodiment.Including judge module 11, the second sending module
12nd, second receive and memory module 13, address determination module 14 and connection establishment module 15.It should be noted that being not limited to Fig. 6
The annexation for showing, can be connected with each other between each module.
Describe the client 10 and its access cluster management device according to the present embodiment in detail with reference to Fig. 5 and Fig. 6
40 managed cluster when each step.
Step S510, judge module 11 judges client 10 in the cluster that cluster management device to be accessed 40 is managed
Whether network access address list is locally stored, the network access address list includes the cluster that cluster management device 40 is managed
Each service server 30 network access address, if locally not storing the network access address list, into step S520；
Conversely, into step S540.
Step S520, the second sending module 12 sends the net for the service server 30 for obtaining to cluster management device 40
The request of network reference address.
Step S530, the second reception and memory module 13 receive and store the network visit that the cluster management device 40 is sent
Ask address.More specifically, receive and request of the storage cluster managing device 40 to service server 30 respond and to client
The network access address list that end 10 is sent.
One of step S540, network access address that address determination module 14 will be stored are defined as the business to be accessed
The objective network reference address of server 30.
Step S550, connection establishment module 15 based on determined by objective network reference address to identified target network
The corresponding service server 30 of network reference address sends service request to obtain the Web content to be accessed.
More specifically, when client 10 will access the cluster that cluster management device 40 is managed, by each step S530
One of network access address for being stored is defined as objective network reference address, business clothes corresponding with objective network reference address
Business device 30 sets up network connection, is then sent to service request to obtain the Web content to be accessed.So, can be in nothing
In the case of need to being forwarded by cluster management device 40, directly using the network access address access service clothes of service server 30
Business device 30.
It should be noted that S510 is optional, using step S510, client 10 is without per secondary to cluster management
The cluster that device 40 is managed obtains network access address list from cluster management device 40 when sending service request, but
The network access address list stored in local memory can be utilized to back up, can so reduce network overhead and delay.
Preferably, in being accessed at each time of the cluster that client 10 is managed cluster management device 40, using poll
Mode uses each network access address that the order determined based on client terminal attribute will be stored successively as objective network
Reference address.
When using polling mode, certain that client 10 will not be in the cluster that is managed of central access cluster management device 40
One service server 30, therefore can preferably realize load balance.Preferably due to when by the way of poll, client
End 10 always since the First service server 30 corresponding to the network access address for being stored access, therefore, it can into
One step is conducted interviews using the order determined based on the attribute of client 10, for example, determine client 10 based on the attribute of client 10
The First service server 30 of wanted poll, because the attribute of each client 10 is different, can so cause wanted poll
First service server 30 is different, so that load is further balanced.
Additionally, in step S530, the second reception and memory module 13 can also be received and net from cluster management device 40
The information relevant with performance and/or loading condition of the corresponding service server 30 of network reference address list.So, can be based on
Service server self performance corresponding with the network access address list and/or the relevant information of loading condition are by each step
One of the network access address stored in rapid S530 corresponding service server 30 is used as objective network reference address.
Additionally, in step S530, the second reception and memory module 13 are not in the reception cluster management device blocked
40 information for sending, but asynchronous carrying out receives, and asynchronous the conditions associated of service server is updated so that
10 can obtain network access address with indiscriminate use S540.
Additionally, address determination module 14 sets up network connection in service server 30 corresponding with objective network reference address
During failure, objective network reference address is redefined.If all accessing failure, indicate that all service servers are current neither
Can use.
Additionally, client 10 can use double buffering（buffer）Storage, each buffer is used for from cluster management
The network access address that device 40 is received, so can effectively reduce the network access address that exclusive reference stored needs frequency
The performance loss of numerous locking.
Client 10 can be using the network access address stored in default order successively each step S530.
It is that client 10 provides each of service to be described in detail with reference to Fig. 6 according to the service server 30 of the present embodiment
Step.
Step S610, the network access address of itself is sent to default cluster management device 40.For example, by the IP of itself
Address and port numbers are registered in cluster management device 40 fake root for representing the cluster that cluster management device 40 is managed
(Fig. 4 is referred under node).
Step S620, the heartbeat message on itself is sent to cluster management device 40, as long as there have heartbeat to indicate that to be available.
For example, can be sent on itself whether available message to cluster management device 40 periodically or according to predetermined interval.This
Outward, the information on self performance and/or loading condition can also be sent to cluster management device 40.
Step S630, the service request at customer in response end 10 sends the content that client 10 is asked with to client 10.
To sum up, because the volume of transmitted data between client 10 or service server 30 and cluster management device 40 does not include visitor
The business tine data that family end 10 is asked to service server 30, therefore data volume greatly reduces, so as to avoid because of cluster pipe
Data bottlenecks phenomenon caused by the data volume of reason device 40 is excessive.
Additionally, when the cluster service scarce capacity of service server 30, can be in the situation for not influenceing current system to run
Under, directly（For example by modes such as hot plugs）Increase service server 30, the service server 30 for newly increasing is to cluster management
Device 40 sends its network access address, and now cluster management device 40 just can at once monitor this event, and by its network
On reference address increase/A nodes, then notify that client 10 updates stored network access address list, so, client
10 soon can be assigned to newly-increased service server 30 a part of service request.So, cluster can quickly be eliminated
Overload problem.
Second embodiment
With reference to Fig. 7, the cluster management system according to the present embodiment includes multiple according to the cluster management of first embodiment dress
40 are put, a cluster for cluster management server is constituted, by the cluster of cluster management server as each service server 30
Manager.Preferably, the cluster of cluster management server includes odd number platform（Such as 3 or 5）Cluster management device 40.When one
When the network access address list of more than half cluster management device 40 is identical, this cluster management device of more than half can be utilized
40 network access address list updates remaining cluster management device 40.The fault-tolerance of whole system can be so improved,
If sub-fraction cluster management device malfunctions, other machines remains to complete the management role to service server 30.
3rd embodiment
With reference to Fig. 8, the cluster management system according to the present embodiment can utilize a cluster pipe according to first embodiment
Reason device 40 is simultaneously multiple different business using the cluster constituted according to a cluster management device 40 of second embodiment
Server cluster provides management service.
Service server according to the present embodiment is substantially the same with above-described embodiment, will not be repeated here.Additionally, client
Most of step with cluster management device 40 is also substantially the same with above-described embodiment.Hereafter only illustrate different from previous embodiment
Part.
When cluster management device 40（Or the cluster of cluster management device 40）Multiple different business services can simultaneously be managed
Device cluster, now, storage is distinguished by the network access address of the service server of different business server cluster.For example, storage
It is different lists, array or the different subtrees being stored as under same virtual tree, to show differentiation.
The network of the service server for obtaining that client sends in step S520 to cluster management device 40 is visited
Asking the request of address includes and the cluster to be accessed or the business to be accessed（Service）Information.
Then, in step S320, cluster management device 40 be based on that the request includes with the cluster to be accessed or to visit
The business asked（Service）Response of the information to be determined as the request to send network access address to client.
With reference to Fig. 8, realized system that employs Zookeeper.Wherein, service server A1 and service server A2 to
Each customer end B 2 provides a kind of business, and service server A3 provides another business to customer end B 1.
Due to when B2 sends network access Address requests, being included in request on wanting access service server A 1 and industry
The information of the business that business server A 2 is provided, therefore the cluster that cluster management device 40 is constituted returns to virtual root node to it
The network access address of each node under "/C "（IP address and port numbers）；And when B1 sends network access Address requests, please
Include the information on the business for wanting access service server A 3 to be provided in asking, therefore cluster management device 40 is constituted
Cluster returns to the network access address of each node under virtual root node "/A " to it（IP address and port numbers）.Such client
B1 and B2 can obtain correct network access address, therefore, it is possible to access the service server of each of which needs.
In the system for management business server cluster for utilizing the Clustering mechanism of LVS to set up, shunted just for
Same server and interface, the cluster if necessary to provide different services for multiple provide management service, then need using many
Individual LVS servers or LVS server clusters.But the cluster management device 40 or cluster management device collection provided using the present embodiment
Group, if the cluster that multiple provides different services provides service, only needs cluster management device 40 by the network of different clusters
