Dynamic weight load balancing method based on Nginx

Abstract

The invention relates to a dynamic weight load balancing method based on Nginx. The method comprises the following steps: acquiring hardware performance of each back-end server node in a no-load state; calculating a hardware influence weight; solving the weight of each server node in a no-load state according to the hardware performance and the hardware influence weight, and taking the weight as the initial weight of a dynamic weight load balancing algorithm; periodically acquiring load information of each back-end server and calculating the use ratio of each piece of hardware; calculating a hardware average performance reference according to the hardware performance; calculating the residual load of each node according to the use ratio of each hardware and the average performance benchmark of the hardware; solving a final weight; allocating a corresponding load to the server according to the final weight; according to the method, the dynamic weight load balancing algorithm based on the weighted polling algorithm is established, so that the dynamic change of the weight is realized, and the problem that the traditional load balancing algorithm cannot change the weight according to the load of the back-end server to cause load imbalance is solved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a dynamic weight load balancing method based on Nginx. Background technique [0002] With the rapid development of the Internet, the number of users is increasing day by day, and more and more requests are sent by users. These requests will generate huge load pressure on the stand-alone server. The development of cluster technology provides a solution to this problem, and load balancing is a cluster technology. very important part of it. Nginx is a high-performance HTTP and reverse proxy web server. It also provides IMAP / POP3 / SMTP services. It is famous for its rich functions, stability, and low system resource consumption, and is loved by many manufacturers. [0003] At present, there are many distribution methods based on Nginx load balancing. For example, the patent application number 201810870243.9 "A Nginx Dynamic Load Balancer Based on WebSocket Long Connecti...

Problems solved by technology

This method solves the problem that the load weight in the traditional static load balancing method cannot be changed according to the actual situation of the system backend server, resulting in load imbalance.

[0004] However, Nginx's built-in load balancing strategies, including round robin, weighted round robin, IPHASH and other algorithms are all static algorithms, and cannot adjust the strategy to distribute requests according to the real-time load of the server, resulting in load imbalance.
