前言
- 很久没有用到tomcat了，因老师需求是springboot项目，所以打算系统整理一下，有些地方也借鉴了其他博文，在此表示感谢。
- tomcat版本：
apache-tomcat-7.0.70
一、目录结构及作用
查看目录：
(base) C02ZT6HWLVDL:apache-tomcat-7.0.70 alsc$ ls -l

-rw-r--r--@ 1 alsc staff 56846 Jun 16 2016 LICENSE
-rw-r--r--@ 1 alsc staff 1239 Jun 16 2016 NOTICE

drwxr-xr-x@ 3 alsc staff 96 Nov 2 17:12 work
(base) C02ZT6HWLVDL:apache-tomcat-7.0.70 alsc$
- bin ：脚本文件目录。
- conf：存放配置文件，最重要的是server.xml。
- lib ：仅对所有WEB APP可见，对TOMCAT不可见（使用Shared类加载器加载）。
- logs：存放日志文件。
- temp：Tomcat运行时候存放临时文件用的。
- webapps：web应用发布目录。
- work：Tomcat把各种由jsp生成的servlet文件放在这个目录下。删除后，启动时会自动创建。
懒得画图，从网上找了一张图，很直观：
二、conf配置文件
1、概述
- 查看：
(base) C02ZT6HWLVDL:conf alsc$ ls -l

-rw-------@ 1 alsc staff 1759 Nov 7 17:17 server.xml
-rw-------@ 1 alsc staff 1950 Jun 16 2016 tomcat-users.xml
-rw-------@ 1 alsc staff 168099 Jun 16 2016 web.xml
- Tomcat 的配置文件由4个 xml 文件构成，
context.xml、server.xml、tomcat-users.xml、web.xml。
a、context.xml
Context.xml 是 Tomcat 公用的环境配置，tomcat 服务器会定时去扫描这个文件。一旦发现文件被修改（时间戳改变了），就会自动重新加载这个文件，而不需要重启服务器。
服务一旦启动，在去修改server.xml，就得需要重新加载配置文件，或者重新启动服务来加载文件。 而context.xml的优势是无需重启。 所以我们一般会在这个文件中独立配置。
b、web.xml
Web应用程序描述文件，都是关于是Web应用程序的配置文件。所有Web应用的 web.xml 文件的父文件。
c、server.xml
server.xml是对tomcat的设置，可以设置端口号，添加虚拟机这些的，是对服务器的设置
d、tomcat-users.xml
Tomcat Manager是Tomcat自带的、用于对Tomcat自身以及部署在Tomcat上的应用进行管理的web应用。Tomcat是Java领域使用最广泛的服务器之一，因此Tomcat Manager也成为了使用非常普遍的功能应用。
Tomcat Manager的用户配置是在Tomcat安装目录/conf/tomcat-users.xml文件中进行管理的
