Fig. 1 show server cluster management system schematic.Wherein, PC is subscriber's main station, is used for visitingAsk server；GW is application delivery gateway device (hereinafter referred to as gateway device), is mainly responsible for serviceThe management of device cluster；Server1 and Server 2 is server, and each station server is configured with multiple phaseSame service node.Such as, the service node 1 on Server1 is identical with service node 2, and port numbers is equalBeing 80, subordinate server IP address is 1.1.1.1.In like manner, the service node 3 on Server 2, serviceNode 4 and service node 5 are identical.
In server set cluster management system, gateway device is responsible for using according to selected load-balancing algorithmThe service request at family balancedly distributes to server.In order to ensure that the server of distribution can be properly functioning,Gateway device to carry out health detection to each station server.
Prior art, when carrying out health detection, is set up with each service node by gateway deviceSocket connects, and is connected by each Socket and initiates to access, obtains the health detection result of correspondence.But, under the collocation method shown in Fig. 1, each server has multiple identical service node, asEach service node is set up Socket connection and is carried out health detection by fruit, will consume substantial amounts of system undoubtedlySystem resource.
For the problems referred to above, the embodiment of the present application proposes a kind of health detecting method, and the method is by clothesBusiness node is classified, and selects a service node to carry out health detection from each class service node, willTesting result shares to other service node in same classification, thus reduces the quantity that Socket connects,Reduce system consumption, meanwhile, also mitigate the performance pressures of server end.
Seeing Fig. 2, for an embodiment flow chart of the application health detecting method, this embodiment is to strongHealth detection process is described.
Step 201, obtains the nodal information of each service node.
Gateway device configures corresponding health detection rule for each service node in advance, and such as, this is good forHealth detected rule can be: uses TCP (Transmission Control Protocol, transmission control protocol)Mode detects.The most also other detection mode, such as UDP (User Datagram Protocol,User Datagram Protocol) mode, SLP (Service Location Protocol, Service Location Protocol) sideFormulas etc., can according to the actual requirements, the health detection rule differently configured to different service nodes.
After completing the configuration of the health detection rule to all service nodes, start health detection process, obtainTaking the nodal information of each server node, this nodal information can include health detection rule, serviceThe IP address of node subordinate server and port numbers etc..Nodal information according to the service node obtained entersRow subsequent treatment.
Step 202, classifies to service node according to nodal information.
The service node with same node point information is classified as a class, particularly as follows:
Perform following sort operation: order selects a unlabelled service node, by these unlabelled clothesBusiness vertex ticks is the execution node of current class.
Perform following vertex ticks of sharing to operate: order selects next unlabelled service node, it is judged thatThis next unlabelled service node is the most identical with the nodal information performing node of current class, ifIdentical, then this next unlabelled service node is labeled as the shared node of current class.
Judge whether that vertex ticks operation is shared in all equal executeds of unlabelled service node, if it is not, thenReturn and perform to share vertex ticks operation；The most then complete the classification to a class service node.
Judge whether the most unlabelled service node；If having, then return and perform sort operation；If nothing,Then complete the classification of all service nodes.
Step 203, selects a service node to carry out health detection from each class service node.
The service node with same node point information is classified as a class by step 202, will be configured withThe service node of identical health detection rule, same server IP address and same side slogan is classified as a class,Now, select wherein any one service node to carry out health monitoring, all can get the healthy shape of serverCondition.In a preferred embodiment, holding in each class service node after gateway device selects to sort outRow node carries out health monitoring.
Step 204, by health detection result-sharing to other service node in same class service node.
Got the health detection result of execution node by step 203 after, by each class service nodePerform node health detection result share to other service node in same class service node respectively.In a preferred embodiment, gateway device will perform the health detection result-sharing of node to sameShared node in class service node.
By foregoing description it can be seen that the application does not carry out health detection to each service node,But be first according to nodal information and sort out, then it is subordinated in multiple service nodes of same classification selectOne service node carries out health detection, and other service node in same classification shares detected serviceThe testing result of node.Thus decrease between gateway device and server the Socket for health detectionConnect quantity, reduce the system resources consumption of gateway device and server.
The most still as a example by Fig. 1, health detection process is discussed in detail.
It is assumed that gateway device GW is respectively service node 1～service node 5 configures health detection rule,Wherein, the health detection rule of service node 1 and service node 2 is TCP detection；Service node 3,The health detection rule of service node 4 and service node 5 is SLP detection.
Gateway device GW starts health detection process, obtains the nodal information of each service node, asShown in table 1.
| Nodename | Health detection rule | IP address | Port numbers |
| Service node 1 | TCP detects | 1.1.1.1 | 80 |
| Service node 2 | TCP detects | 1.1.1.1 | 80 |
| Service node 3 | SLP detects | 2.2.2.2 | 8080 |
| Service node 4 | SLP detects | 2.2.2.2 | 8080 |
| Service node 5 | SLP detects | 2.2.2.2 | 8080 |
Table 1
Above-mentioned service node is sorted out by gateway device.First, it is labeled as performing joint by service node 1Point, it is judged that service node 2 whether with the nodal information of service node 1 (health detection rule, IP address,Port numbers) identical, as shown in Table 1, service node 2 is identical with the nodal information of service node 1, because ofThis, be labeled as service node 2 sharing node.
Order judges that service node 3 is the most identical with the nodal information of service node 1, as shown in Table 1,Service node 3 differs with the nodal information of service node 1, and therefore, service node 3 cannot function as clothesThe shared node of business node 1, is not belonging to same class service node.In like manner, service node 4, service jointPoint 5 is not the shared node of service node 1.
After classifying the first time of above-mentioned service node, service node 1 and service node 2 are sameClass service node, and service node 1 is for performing node, service node 2 is for sharing node.
Starting second time classification, from table 1, order selects a unlabelled service node, i.e. services jointPoint 3, is labeled as service node 3 the execution node of current class, selects next unlabelled serviceNode, i.e. service node 4, it is judged that service node 4 is the most identical with the nodal information of service node 3,As shown in Table 1, service node 4 is identical with the nodal information of service node 3, therefore, by service nodeThe 4 shared nodes being labeled as current class.In like manner, service node 5 is labeled as sharing of current classNode.
After completing above-mentioned double classification, all service nodes are the most marked, wherein, and service node 1 HeService node 3 is for performing node, and gateway device is only set up Socket with execution node and is connected, and sends healthProbe messages carries out health detection, if server normal operation, will respond the detection of gateway device, fromAnd make gateway device confirmed service device normal operation.
Health detection result-sharing, after obtaining the health detection result performing node, is given same by gateway deviceShared node in one classification.Such as, by the health detection result-sharing of service node 1 to service node2, by the health detection result-sharing of service node 3 to service node 4 and service node 5.
