Nginx Load Balancer Configuration

A: Introduction

Tomcat handles dynamic requests in highly concurrent environments with low performance and is more vulnerable to handling static pages. Although the latest version of Tomcat supports Epoll, it is much better to handle static pages through Nginx than with Tomcat.

Two: Download the installation (take the Windows environment as an example)

1. Download Address
Download Address: Click here

2. Directory structure

  Nginx-           |_  conf   配置目录           |_  contrib           |_  docs 文档目录           |_  logs  日志目录           |_  temp 临时文件目录           |_  html 静态页面目录           |_  nginx.exe 主程序

Three: Start and stop Nginx service

CMD into Nginx unzip directory

Execute start Nginx to start the service (either Nginx or Nginx.exe)
It is recommended to use the first type,
The other two will keep your cmd window in execution and cannot be manipulated by other commands

Perform nginx-s stop to stop Nginx service

Execute nginx-t to check that the Nginx configuration file is correct.

Four: nginx main configuration file nginx.conf

V: Load Balancing weight configuration

    upstream localhost {      server localhost:8080 weight=5;      server localhost:9091 weight=1;     }

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the Nginx load balancing configuration, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
