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.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 -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful [root@localhost conf.d]# systemctl reload nginx 3.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 <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
[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 <meta> <title>测试动静分离</title> <script></script><script> $(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> <h2>测试动静分离</h2> <h2>上面为静态图片，下面为动态页面</h2> @@##@@ <div></div>
2.5.效果
看着是一个页面实则不同机器在做处理
