nginx+tomcat動靜分離

Nginx動靜分離簡單來說就是把動態跟靜態請求分開，不能理解成只是單純的把動態頁面和靜態頁面物理分離。嚴格意義上說應該是動態請求跟靜態請求分開，可以理解成使用Nginx處理靜態頁面，Tomcat處理動態頁面。

一定要把圖片全放在/usr/local/nginx/html/jsz路徑下，不然網頁不顯示圖片

配置後端Tomcat服務器，這裏省略哦，啓動2個tomcat

最後檢查Nginx配置是否正確即可，然後測試動靜分離是否成功，刪除後端tomcat服務器上的某個靜態文件，查看是否能訪問，如果可以訪問說明靜態資源nginx直接返回了，不走後端tomcat服務器。
