nginx+tomcat动静分离

Posted 2020-07-17

nginx动静分离简单来说就是把动态跟静态请求分开，不能理解成只是单纯的把动态页面和静态页面物理分离。严格意义上说应该是动态请求跟静态请求分开，可以理解成使用Nginx处理静态页面，Tomcat处理动态页面。

nginx主配置文件

vhosts.conf内容

    location ~ .*\.(jsp|cgi|shtml)?$
    {

    }
                access_log  /usr/local/nginx/logs/access.log;
                error_log   /usr/local/nginx/logs/error.log;

   }

一定要把图片全放在/usr/local/nginx/html/jsz路径下，不然网页不显示图片

配置后端Tomcat服务器，这里省略哦，启动2个tomcat

最后检查Nginx配置是否正确即可，然后测试动静分离是否成功，删除后端tomcat服务器上的某个静态文件，查看是否能访问，如果可以访问说明静态资源nginx直接返回了，不走后端tomcat服务器。
