nginx处理静态
tomcat处理动态
合并为动静分离(前后端分离)
bin:存放启动和关闭Tomcat脚本
conf:存放Tomcat不同的配置文件
doc:存放Tomcat文档
lib/japser/common:存放Tomcat运行需要的库文件
logs:存放Tomcat执行时的LOG文件
src:存放Tomcat的源代码
webapps:Tomcat的主要Web发布目录
1.Nginx处理静态页面的效率远高于Tomcat的处理能力
2.如果Tomcat的请求量为1000次,则Nginx的请求量为6000次
3.Tomcat每秒的吞吐量为0 6M,Nginx的每秒吞吐量为3.6M
4.Nginx处理静态资源的能力是Tomcat处理的6倍,优势可见一斑
