- 一、动静分离是什么
- 1. 概念
- 二、配置动静分离
- 1.1环境准备
- 1.2 准备工作
- 1.3 安装httpd服务
- 1.4 开启服务
- 1.5 修改agent主机配置文件
- 1.6 使用agent主机IP地址访问测试
- 1.6.1 访问静态资源
- 1.6.2 访问动态资源
动静分离，通过中间件将动态请求和静态请求进行分离；可以减少不必要的请求消耗，同时能减少请求的延时。
通过中间件将动态请求和静态请求分离，逻辑图如下:
| 主机名 | IP | 服务 | 系统 |
|---|---|---|---|
| lnmp | 192.168.47.169 | lnmp架构 | centos8 |
| agent | 192.168.47.160 | nginx | centos7 |
| httpd | 192.168.47.130 | httpd | redhat8 |
