Description
Technical Field
The present invention relates to computer technology, and more particularly, to a health check method and apparatus, a health check control method, and a controller.
Background
Cloud computing is built on a large network, and messages need to be communicated with a wide area network through an internal network. Load Balance (LB) is a necessary service, LB is a technology for balancing access traffic of a client to a plurality of back-end servers (RS), and RS is a cloud host in a cloud computing environment. LB provides load balancing function for the incoming and outgoing flow, and at the same time needs Health Check (HC) for RS. The HC detects the server software of the client running on the cloud host, adjusts the message forwarding rule according to the detection result, timely eliminates unhealthy back-end services, and ensures the availability of the whole service.
In the related art, an LB node (which may also be referred to as an LB server) running a load balancing service is generally deployed as a distributed cluster, and a health check is implemented by an HC device thereon, which may be implemented by using an HC component deployed on the LB node.
The related art realizes the health check mode including:
the first way, independent health examination.
Each LB node in the cluster runs an HC device for performing health check on all RSs independently, and the LB node adjusts the load balancing policy according to the local check result, as shown in fig. 1.
When the method is adopted, because each LB node independently performs health check, the check task of each node is the same, calculation and network resources are wasted, and meanwhile, the capacity and the expansibility cannot meet the continuous growth of services, because the service capacity depends on the resources of a single LB node, the increased nodes cannot expand the capacity. If the health check service of the HC device of a certain LB node goes wrong, the forwarding strategy of the LB where it is located is directly affected, and disaster tolerance is not possible.
Mode two, centralize the health check.
All health checks are performed on a certain HC node (or called health check center), the HC node synchronizes the check results to each LB node in the cluster, and the LB node adjusts the load balancing policy according to the remote check results, as shown in fig. 2.
When the method is adopted, because health check is carried out on the centralized HC node, the problems of redundancy and repetition of check are solved, one RS is checked only once, but because the health check is carried out on one HC node, the disaster tolerance is poor. In addition, the detection result needs to be synchronized from the HC center to the LB, and the delay of this synchronization may cause a scheduling policy that cannot adjust load balancing in time. Moreover, since the HC node is set independently of the LB node, the network path (HC < - > RS) for checking traffic is different from the network path (LB < - > RS) for actual traffic, and the checking result may be different from the detection result when the independent health check method is adopted.

The change of the HC device may be caused by various conditions, such as the HC device being on-line, the HC device being off-line, an abnormality occurring in the HC device, and so on. When an HC device is brought online, it is necessary to reduce the number of objects to be inspected of the existing HC device and distribute the objects to the newly brought-online HC device.

EXAMPLE III
The embodiment provides a health check system, which comprises HC devices in a cluster and an HC controller, wherein the HC devices adopt the HC devices in the first embodiment, and the HC controller adopts the HC controller in the second embodiment.
The distributed health check scheme of the embodiment has the following technical effects:
1) the HC controller is added, the HC controller intelligently distributes the inspection tasks, and different HC devices inspect different inspection objects, so that the redundancy problem is solved, and the calculation and network resources are not wasted. The capacity of health examination is improved by times. Meanwhile, the capacity can be expanded by adding the HC device, and the continuous increase of services is met. Has the characteristics of large capacity and high availability.
2) Since each HC device only performs health check on a part of the RSs which need health check, when a certain HC device has a problem, if the check cannot be performed or the check result is wrong, the influence range is reduced to 1/n of the original value, and n is the number of the HC devices. Moreover, the service can be quickly recovered through the re-distribution task of the HC controller, and the disaster tolerance is good.
3) Because the HC means is deployed on the LB node, the LB may adjust the scheduling policy for load balancing in time according to the result of the health check, for example, to remove unhealthy RSs from the forwarding configuration. .
4) The network path of the health check is consistent with the LB service flow, and the accuracy of the check result can be improved.
Example four
The present embodiment provides an example of a health check based on embodiments one and two.
Referring to fig. 7, the cluster shown in the figure is an LB cluster formed by LB nodes, the HC apparatus is disposed on the LB nodes, the check objects are RSs, the RSs are RSs related to LB cluster scheduling, and the LB nodes may schedule traffic to any RS therein. As an example, an LB cluster includes 3 LB nodes, represented in the figure as LB1-LB 3. And the object to be examined includes 6 RSs, which are shown as RS1-RS 6.
As shown in the figure, a HC controller is provided in the system, and the HC controller may be physically provided in a separate machine or may be provided in combination with the LB node. The HC controller is configured to assign one or more RSs as inspection targets to HC devices in the cluster. In the illustrated example, the HC controller allocates 6 RSs to 3 HC nodes on average for checking, where RS1 and RS2 are allocated to HC1, RS3 and RS4 are allocated to HC2, and RS5 and RS6 are allocated to HC 3. The RS allocated to different HC nodes is different. The HC controller establishes connection with HC devices in the cluster through the network, and respectively issues inspection tasks to each HC device, and the RS to be inspected is indicated in the inspection tasks. For example, RS1 and RS2 are indicated in the inspection tasks delivered to HC1, RS3 and RS4 are indicated in the inspection tasks delivered to HC2, and RS5 and RS6 are indicated in the inspection tasks delivered to HC 3.
And after receiving the checking task, the HC device on each LB node performs health check on the RS indicated in the checking task. In this example, HC1 would health check RS1 and RS2, HC2 would health check RS3 and RS4, and HC3 would health check RS5 and RS6, with different HC devices checking for different RSs. After the health check is completed, the results of the health check are synchronized with each other among the respective HC devices through the network, and for example, after the health check is completed, the HC1, HC2, and HC3 all broadcast their own check results to the other HC devices. Each HC device is made available to obtain the full amount of inspection results, and after synchronization, in this example, each HC of HC1, HC2, and HC3 will get the health inspection results of RS1-RS6 for scheduling to achieve load balancing, e.g., rejecting unhealthy RS and adding healthy RS.
If the HC1 is abnormal during operation, so that the health check results of RS1 and RS2 cannot be obtained, the health check results of RS3-RS6 can be normally obtained by HC2 and HC 3. When the HC controller finds that HC1 is abnormally off-line, tasks are redistributed, RS1 in charge of HC1 is redistributed to HC2, RS2 in charge of HC1 is redistributed to HC3, and new checking tasks are issued to HC2 and HC 3. After receiving the new checking task, HC2 and HC3 can respectively start the health check of RS1 and RS2, and have good disaster tolerance and high recovery speed.
