The present application relates to the field of communications technologies, and in particular, to a health check method, apparatus, device, and computer-readable storage medium.
Background
With the continuous development of network technology, the network flow is larger and larger, a single server cannot meet the requirements of users on high concurrency, high new construction and high processing speed, and meanwhile, the cost performance of hardware upgrading of the server is too low.
In order to increase the service processing capacity and the service processing speed, a server load balancing technology is developed. The load balancing equipment has the functions of detecting the running state of the real servers and reasonably scheduling the flow of the client to one or more real servers according to the running state of the servers, so that the running state of the servers can be accurately judged, and the load balancing equipment has important significance in flow scheduling.
At present, the technical solutions for detecting the operating state of a server include the following two types:
one solution is to use an Internet Packet explorer (Packet Internet Groper, ping for short) to periodically ping a server through an Internet Control Message Protocol (ICMP) to detect whether a network is reachable, which has the defect that if the network has no problem but the service has a problem, the network cannot be detected. Another scheme is to access a server application at regular time, and if the server application is an application based on a hypertext Transfer Protocol (HTTP), health check can be performed by establishing a Transmission Control Protocol (TCP) connection, or an HTTP request can be sent to a web server, and availability of a service or a server can be detected by detecting whether access is normal.
In the above scheme, the load balancer may need to perform health status on hundreds of servers, even thousands of servers, and the load balancer is very stressed and can bear heavy burden, especially for performing health check on encrypted servers, such as HTTPS servers, because encryption and decryption are performed, performance consumption is huge. If the health check detection request is sent to thousands of servers at regular intervals and the responses of the servers are processed in time, a large amount of resources of the server to which the load balancer belongs are occupied, and meanwhile, the load balancer needs to process a request scheduling forwarding message and perform a large amount of health check at the same time, the performance of the load balancer is affected, and the scheduling effect is further affected.

Before describing the embodiments of the present application, the following terms of art to which the embodiments of the present application relate, including load balancing and health checking, will be described first.
1. Load balancing
Load Balance (LB) is a clustering technique for servers or network devices. Load balancing distributes specific services (such as network services, network traffic and the like) to a plurality of servers or network devices, thereby improving service processing capacity and ensuring high availability of the services. The server load balancing is divided into four-layer server load balancing and seven-layer load balancing according to the message layers processed by the LB equipment: processing an IP header of an Internet Protocol (IP) packet by four layers without analyzing more than four layers of loads (L4 server LB) of the message; the seven layers process to a message payload portion, such as a hypertext Transfer Protocol (HTTP), a Real Time Streaming Protocol (RTSP), a Session Initiation Protocol (SIP) header, and sometimes a message content portion (L7 server LB).
2. Health examination
The load balance judges the service availability of the server through health check, and the health check mechanism improves the overall service availability and avoids the influence of server abnormity on the overall service. After the health check function is started, when a certain server is checked to be abnormal, the load balance can automatically distribute a new request to other servers with normal health check; and when the server returns to normal operation, the load balancing can automatically return the server to the load balancing service.
Generally, a load balancing device generally includes a control plane and a data forwarding plane, the control plane is responsible for configuration management, reporting, health check, and the like, the data forwarding plane is responsible for message transmission and reception, four-layer load balancing, seven-layer load balancing, load scheduling, and the like, and all functions of the data forwarding plane are completed on one device. Even for the frame device, the frame device is divided into a main control board and a service board, the main control board mainly processes a load control board, because the general performance of the main control board is weaker, health check is performed on a large number of servers, the pressure is very high, and the performance is difficult to be satisfied, and especially when the back-end server is a Secure Socket Layer (SSL) server, because encryption and decryption are involved, the performance consumption is especially high, and the performance and stability of the load balancing device are seriously affected.
Therefore, the embodiment of the present application provides a health check method, and in particular, a method for performing health check on a large number of servers, which can detect the operating condition of a backend server in real time, thereby reducing the burden of the existing load balancer, improving the real-time performance and accuracy of health monitoring results, and further improving the performance of the load balancer.
According to the embodiment of the application, the health check module of the load balancer is separated and deployed on an independent health check device, and the health check device can be an independent server. The health check equipment and the load balance equipment can communicate through a restful interface or other types of available interfaces, the health check equipment can select server hardware according to the number, functions and the like of the back-end servers which need to be detected, decoupling of the load balance equipment and the back-end servers in the aspect of health check is achieved, and linear expansion of health check performance is achieved.
The following describes the health examination method provided in the embodiments of the present application in detail.
Referring to fig. 1, a schematic flow chart of a health check method provided in an embodiment of the present application is applied to a health check system, where the health check system includes a load balancing device and at least two health check devices connected to the load balancing device. Specifically, for each health check device, the health check device may be a server, and a health check platform is deployed on the server, so that the load balancing device may perform health check on a large number of backend servers by using at least two external health check platforms; in addition, in order to realize the communication between the load balancing device and the health check device, the IP address and port of each health check device can be configured on the load balancing device.
It should be noted that, generally speaking, the embodiment of the present application needs at least two health check devices, and when a problem occurs in a certain health check device, another health check device may be selected to continue health check, so as to avoid the situation that health check cannot be performed.
The steps of the health check method shown in fig. 1, whose execution subject is a load balancing device, will be described below with reference to the schematic diagram of the health check system shown in fig. 2, and the method includes the following steps:
s101: the health check policy is synchronized to at least two health check devices.
In this embodiment of the present application, a health check policy may be configured on the load balancing device, and then the load balancing device synchronizes the health check policy to each external health check device. The embodiment of the present application does not limit the used synchronous interface, such as a restful interface.
In fig. 2, the load balancing device may include an external health examination platform configuration module, a heartbeat module, and a health examination switching module, and the load balancing device may complete a policy configuration function for each health examination device by using the external health examination platform configuration module (i.e., S101).
In addition, after receiving the health check policy configured by the load balancing device, each health check device may store configuration content in a corresponding database, where the policy content may include health check configurations such as an IP and a port of a server to be detected, a detection mode and a detection period of the server, and a health check enabling switch.
In fig. 2, the health check device includes a configuration receiving module, a heartbeat module, and a health check module, and the health check policy synchronized by the load balancing device may be received by the configuration receiving module.
S102: and selecting one health check device from the at least two health check devices as a main health check device, wherein the main health check device is used for carrying out health check on the at least one back-end server according to a health check strategy.
In this embodiment, the load balancing device may select one of the health check devices (i.e., select an external health check platform) as a main health check device, and the main health check device is a device in a normal operating state. The main health check equipment can perform health check on each back-end server needing health check according to the health check strategy, and other health check equipment except the main health check equipment only needs to store the configured health check strategy, and the health check on the back-end server is not needed temporarily.
In fig. 2, the primary health check device may be selected by an external health check platform configuration module of the load balancing device.
When the load balancing device authorizes a certain health check device as a main health check device, the main health check device can turn on the health detection switch to start health check, and at the moment, the main health check device informs the background health check process to perform health check.
In fig. 2, the health check module of the main health check device may perform health check on each backend server according to the health check policy.
Further, the health check method provided by the embodiment of the application may further include the following steps a1-a 2:
step A1: and determining whether the main health check equipment is abnormal equipment or not by monitoring the working state of the main health check equipment.
In order to ensure that health examination is performed on each back-end server, real-time state monitoring needs to be performed on the current main health examination device to ensure that the main health examination device can perform health detection normally, and if a problem occurs in the current main health examination device, another health examination device can be replaced to serve as the main health examination device to continue health examination.
In an implementation manner of the embodiment of the present application, step a1 may specifically include: monitoring the working state of the main health check equipment by establishing a long connection heartbeat with the main health check equipment; and if the state information fed back by the main health check equipment is not received within the preset time length, determining that the main health check equipment is abnormal equipment.
In this implementation manner, a long connection heartbeat channel is established between the load balancing device and each external health check device, the status of each health check device is monitored according to a preset time interval (e.g., every 1 second), and each health check device needs to report its own status information to the load balancing device according to the preset time interval (every 1 second). For the main health check device, if the main health check device does not report the status information after a preset time (for example, 5 seconds) is exceeded, the load balancing device considers that the main health check device has a problem, that is, the main health check device is considered to be an abnormal device
Step A2: and if the main health check equipment is determined to be abnormal equipment, selecting one normal equipment from at least two health check equipments to replace the main health check equipment.
When the load balancing device considers that the current main health check device is an abnormal device, the load balancing device selects a normal health check device from the rest health check devices as a new main health check device, and sends a switching message to the new main health check device through the heartbeat connection channel to inform the new health check device to start health detection on each back-end server.
In fig. 2, the heartbeat-related functions may be performed by the heartbeat modules of the load balancing device and the health check device; in addition, the health check switching module of the load balancing device can replace the current abnormal main health check device and select a new main health check device.
Further, in the health check method provided in the embodiment of the present application, the method may further include: and if the abnormal equipment (namely the main health check equipment with the problem) returns to be normal, sending a first notice to the abnormal equipment, wherein the first notice is used for informing the abnormal equipment to close the health check function.
Specifically, the load balancing device needs to detect the states of all health check devices, and if a health check device with a problem returns to normal again, that is, the abnormal device returns to normal again, a first notification needs to be sent to the abnormal device to notify the abnormal device to turn off the health detection function, so that an external health check device is always maintained to perform health detection.
Further, in the health check method provided in the embodiment of the present application, the method may further include: and if the at least two health check devices are abnormal devices, the load balancing device performs health check on the at least one back-end server according to a health check strategy.
Specifically, a health check policy (which may be configured by an external health check platform configuration module shown in fig. 2) needs to be configured for the load balancing device in advance, and when a normal health check device exists, the health check device is adopted to perform health check, and the load balancing device is not required to perform health check; on the contrary, when all the health check devices have problems, the health check can be performed by switching to the load balancing device (the health check switching module shown in fig. 2 may perform switching), that is, the load balancing device performs health check on all the backend servers, but the load balancing device continuously detects each health check device, and if a normal health check device is found, the health check device is switched to a certain normal health check device to perform health check (the health check switching module shown in fig. 2 may perform switching).
It should be noted that, the embodiment of the present application does not limit the health check manner, and any existing or future health check manner may be adopted to check the backend server. In addition, regarding "health check on at least one backend server", it is usually necessary to perform health check on all backend servers, but if there is a certain need, health check may be performed on only some backend servers.
Referring to fig. 3, a schematic flow chart of another health check method provided in the embodiment of the present application is applied to a health check system, where the health check system includes a load balancing device and at least two health check devices connected to the load balancing device; in addition, the load balancing device may select one health check device from the at least two health check devices as a main health check device.
The execution subject of the method is a master health check device, the method comprising the steps of:
s301: receiving a health check strategy sent by load balancing equipment;
s302: and performing health check on at least one back-end server according to the health check strategy.
Further, in the health check method provided in the embodiment of the present application, the method may further include: sending the state information of the main health check equipment to the load balancing equipment according to a preset time interval; the load balancing device is used for determining that the main health check device is abnormal when the state information fed back by the main health check device is not received within the preset time length, and selecting one normal device from the at least two health check devices to replace the main health check device.
It should be noted that the health check methods shown in fig. 1 and fig. 3 respectively use the load balancing device and the main health check device as execution main bodies, and therefore, for specific description of each step of fig. 3, reference may be made to relevant contents of the above-mentioned embodiment of fig. 1, and details are not repeated here.
Further, in the health check method provided in the embodiment of the present application, the method may further include: and sending the result of the health check of the back-end server to the load balancing equipment.
Specifically, the master health check device may send the health check result for each backend server to the load balancing device at preset time intervals, for example, through a restful interface (which may be performed by the health check module shown in fig. 2). After receiving the health check result sent by the main health check device, the load balancing device may update the server health list by using the health check result to instruct the server load balancing module of the load balancing device to forward the data packet.
Therefore, the health examination module of the load balancing equipment can be separated, the function of the health examination module is realized by the external health examination equipment, the decoupling of the load balancing equipment and the rear-end server in the aspect of health examination is realized, and the linear expansion of the health examination performance is realized. The load balancing equipment and the external health check equipment respectively play their own roles, so that the scheduling performance of the load balancing equipment is enhanced, the equipment resources of the load balancing equipment are saved, and the influence on the function of the load balancing equipment due to the health check function is avoided.
In the health check method provided by the application, the load balancing device synchronizes the health check policy to each health check device, and the load balancing device further selects one health check device from the health check devices as a main health check device, and then the main health check device can perform health check on each backend server according to the health check policy.
