Today, I will talk to you about how nginx can achieve load balancing. maybe many people don't know much about it. In order to make you understand better, the editor summarizes the following contents. I hope you can get something from this article.

Load balancing is based on the existing network structure, which provides a way to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capacity, and improve network flexibility and availability. Load balancing, distributed to multiple operating units for execution, such as Web server, FTP server, enterprise critical application server and other critical task servers, so as to complete the work task together.

Nginx is a http server. Load balancing is a common function of nginx. In order to avoid server crash and let users have a better experience, load balancing is used to share the server pressure. Many servers can be set up to form a server cluster. When users visit a website, they first visit an intermediate server, then let the intermediate server select a less stressful server in the server cluster, and then introduce the access request to the server. In this way, each user visit will ensure that the pressure of each server in the server cluster tends to balance, share the server pressure, and avoid the server crash. Generally speaking, the configuration of load balancer needs to configure reverse proxy at the same time, and jump to load balancer through reverse proxy.

The load balancing strategy of nginx can be divided into two categories: built-in strategy and extended strategy. The built-in policies include weighted polling and ip hash, which are compiled into the nginx kernel by default, simply by specifying the parameters in the nginx configuration. There are many extension strategies, such as fair, generic hash, consistent hash, etc., which are not compiled into the nginx kernel by default.

When nginx is needed to achieve load balancing, this wave of operation needs to understand the relevant professional technology. If you know the technology, you can operate it on your own; if you do not have the relevant professional knowledge and technology, you can contact the server provider for help.

Load balancer EasySLB service, that is, automatic distribution of application traffic among multiple CVMs. It can realize automatic fault switching, improve business availability, and improve resource utilization. Cloud load balancer activation management process:

1. Activate web server and file server

two。 To activate the load balancer, you need to select the "load balancer" template to activate it.

3. Go to the management scheduler server and add a back-end server.

The above are the answers about how to achieve load balancer in nginx. Load balancer EasySLB, one-click operation, building web cluster, and technology rookies can also play load balancer, which makes deployment easier, monitoring more intuitive, and fault handling more intelligent.

After reading the above, do you have any further understanding of how nginx implements load balancing? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
