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 proxy | 192.168.81.210 |
| centos7.5 | 静态资源 | Nginx static | 192.168.81.220 |
| centos7.5 | 动态资源 | Tomcat server | 192.168.81.230 |
2.2.配置静态资源
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | 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 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | 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 <title>JSP Test Page</title>Random number:"); out.println(rand.nextInt(99)+100); %> 3.启动服务[root@localhost application]# cd apache-tomcat-7.0.92/[root@localhost apache-tomcat-7.0.92]# ./bin/startup.sh |
2.4.整合动静分离
2.4.1.配置动静分离负载均衡
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | [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 $proxy_add_x_forwarded_for; }} |
2.4.2.编写整合动静分离代码
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | [root@localhost conf.d]# vim /web/ds/index.html <title>测试动静分离</title>$(document).ready(function(){ $.ajax({ type: "GET", success: function(data) { $("#get_data").html(data) }, error: function() { alert("fail!!,请刷新再试"); } });});<h1>测试动静分离</h1> <h1>上面为静态图片，下面为动态页面</h1> |
2.5.效果
看着是一个页面实则不同机器在做处理
