关于Nginx动静分离详解以及配置
1.Nginx动静分离概念
动静分离，通过中间件将动态请求和静态请求进行分离，分离资源，减少不必要的请求消耗，减少请求延时。
好处：动静分离后，即使动态服务不可用，但静态资源不会受到影响
通过中间件可以将动态请求和静态请求进行分离
2.Nginx动静分离应用案例
2.1.环境规划
系统服务服务地址centos7.5负载均衡Nginx proxy192.168.81.210centos7.5静态资源Nginx static192.168.81.220centos7.5动态资源Tomcat server192.168.81.2302.2.配置静态资源
1.创建动静分离配置文件[root@localhost ~]# cd /etc/nginx/conf.d/[root@localhost conf.d]# vim ds.conf#动静分离server { listen 80; server_name ds.com; location / { root /web; index index.html; } location ~* .*\.(png|jpg|gif)$ { root /web/images; }}2.重载Nginx[root@localhost conf.d]# nginx -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful[root@localhost conf.d]# systemctl reload nginx3.准备图片[root@localhost conf.d]# mkdir /web/images[root@localhost conf.d]# wget -O /web/images/nginx.png http://nginx.org/nginx.png
2.3.配置动态资源
1.编译安装tomcat[root@localhost soft]# tar xf apache-tomcat-7.0.92.tar.gz -C /application/2.写入动态文件[root@localhost soft]# cd /application/[root@localhost application]# vim apache-tomcat-7.0.92/webapps/ROOT/java_test.jsp<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><HTML> <HEAD><TITLE>JSP Test Page</TITLE> </HEAD> <BODY> <%Random rand = new Random();out.println("<h1>Random number:</h1>");out.println(rand.nextInt(99)+100); %> </BODY></HTML>3.启动服务[root@localhost application]# cd apache-tomcat-7.0.92/[root@localhost apache-tomcat-7.0.92]# ./bin/startup.sh2.4.整合动静分离
2.4.1.配置动静分离负载均衡
[root@localhost conf.d]# vim lb_ds.conf#整合动静分离upstream static_photo {server 172.16.1.20:80;}upstream java {server 172.16.1.30:8080;}server {listen 80;server_name ds.com;access_log /nginx_log/lb_ds_access.log main;location / {root /web/ds;index index.html;}location ~* .*\.(jpg|png|gif)$ {proxy_pass http://static_photo;proxy_set_header HOST $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}location ~* .jsp$ {proxy_pass http://java;proxy_set_header HOST $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}}2.4.2.编写整合动静分离代码
[root@localhost conf.d]# vim /web/ds/index.html<html lang="en"><head><meta charset="UTF-8" /><title>测试动静分离</title><script src="http://libs.baidu.com/jquery/2.1.4/jquery.min.js"></script></head><script type="text/javascript">$(document).ready(function(){$.ajax({type: "GET",url: "http://ds.com/java_test.jsp",success: function(data) {$("#get_data").html(data)},error: function() {alert("fail!!,请刷新再试");}});});</script><body><h1>测试动静分离</h1><h1>上面为静态图片，下面为动态页面</h1><img src="http://ds.com/nginx.png"><div id="get_data"></div></body></html>2.5.效果
看着是一个页面实则不同机器在做处理
