nginx處理靜態
tomcat處理動態
合并為動靜分離(前后端分離)
bin:存放啟動和關閉Tomcat腳本
conf:存放Tomcat不同的配置文件
doc:存放Tomcat文檔
lib/japser/common:存放Tomcat運行需要的庫文件
logs:存放Tomcat執行時的LOG文件
src:存放Tomcat的源代碼
webapps:Tomcat的主要Web發布目錄
Nginx靜態處理優勢
1.Nginx處理靜態頁面的效率遠高于Tomcat的處理能力
2.如果Tomcat的請求量為1000次,則Nginx的請求量為6000次
3.Tomcat每秒的吞吐量為0 6M,Nginx的每秒吞吐量為3.6M
4.Nginx處理靜態資源的能力是Tomcat處理的6倍,優勢可見一斑
動靜分離原理:服務端接收來自客戶端的請求中,既有靜態資源也有動態資源
