Problems solved by technology

However, in practical applications, server clusters often have load imbalance problems: some servers are running under high load, while other servers are idle.
However, when there are many requests for a certain type of business, the corresponding group of servers will be under high load, while the servers of other groups will be idle

Embodiment Construction

[0037] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] A kind of NGINX server load balancing system provided by the present invention, such as figure 1 As shown, it mainly includes clients, NGINX servers, and backend server clusters.

[0039] Client: The user sends various HTTP requests to the server through the terminal device. The request will first pass through the NGINX server responsible for load balancing, and then be forwarded to the back-end server cluster.

[0040] NGINX server: responsible for receiving HTTP requests from clients. First, analyze the business type of the request URL, and then use the load balancing algorithm to select a reasonable back-end server to process the HTTP request based on the business type and dynamically collected back-end server cluster resource information. The server processing results are returned to the client.

[0041] Back-end server cluster...

Abstract

The invention relates to an implementation method and a system for NGINX server load balancing, and belongs to the field of computer network communications. The implementation method provided by the invention comprises the following steps: adopting a triggering mechanism to dynamically update resource information of a backend server cluster via an NGINX server, then calculating a load value of a backend server under each service type according to the resource information of the backend server cluster and different service types, and processing an HTTP request by selecting a backend server of which the load value is the smallest in the service type to which the HTTP request belongs. The invention further provides a corresponding system for NGINX server load balancing. According to the implementation method and the system, requests of a user can be distributed reasonably to ensure that the load of the back-end server cluster is in a relatively balanced state. Therefore, the purpose of reasonable use of the server resource is achieved.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to a method and system for realizing NGINX server load balancing. Background technique [0002] The emergence of server clusters solves the problem of massive web concurrent access. However, in practical applications, server clusters often have the problem of unbalanced load: some servers are running with high load, while other servers are idle. [0003] As a high-performance load balancing server, NINGX server is widely used in server clusters. The main method to achieve load balancing is the polling method, which evenly selects the back-end server to process the request. In the case of differences in server performance, a weighted round-robin method can be used, so that the ratio of allocated servers is proportional to its weight. Since the requested business content is different, the requirements for server resources are also different. Considering the requested b...
