linux CentOS7 下 Nginx +Tomcat 动静分离（亲测非转载）

动静分离不解释了，理论网上一堆一堆的，但实现手段我理解就是特定的请求使用特定的处理方式。

nginx安装可以参考这个：

tomcat安装可以参考这个：

仅作为演示使用，以图片为例。  
首先将tomcat下root文件夹下.png图片剪切至nginx下html下。  
这时访问tomcat应该看不到图片了，如果能看到，那么请清理浏览器缓存。

然后配置nginx。

主要配置有三处。  
1、http节点增加代理  
 upstream drugs\{  
      server 192.168.2.4:8080; \#tomcat地址  
    \}  
2、server处增加tomcat代理与图片解析目录  
      \#代理tomcat  
        location / \{  
            proxy\_pass http://drugs;  
        \}  
        \#图片解析目录  
      location ~ .\*\\.(png|jpg)$ \{  
            root html;  
        break;  
        \}  
3、打开日志的注释。（会看日志很重要）  
 log\_format  main  '$remote\_addr - $remote\_user \[$time\_local\] "$request" '  
                      '$status $body\_bytes\_sent "$http\_referer" '  
                      '"$http\_user\_agent" "$http\_x\_forwarded\_for"';

access\_log  logs/access.log  main;

4、运行成功，如果不成功就看日志，日志中如果有这个关键词“Permission denied”，那就是没权限读取图片，将nginx.conf的\#user root;解除注释，reload在尝试访问ok。  
以下是nginx全配置，tomcat的jsp页面不用修改。
