commands:
debug Start Catalina in a debugger
debug -security Debug Catalina with a security manager
jpda start Start Catalina under JPDA debugger
run Start Catalina in the current window
run -security Start in the current window with security manager
start Start Catalina in a separate window
start -security Start in a separate window with security manager
stop Stop Catalina, waiting up to 5 seconds for the process to end
stop n Stop Catalina, waiting up to n seconds for the process to end
stop -force Stop Catalina, wait up to 5 seconds and then use kill -KILL if still running
stop n -force Stop Catalina, wait up to n seconds and then use kill -KILL if still running
version What version of tomcat are you running?
Note: Waiting for the process to end and use of the -force option require that $CATALINA_PID is defined

验证：成功打开浏览器，
一、tomcat的目录结构：
bin: 脚本及启动时用到类；
lib：类库；
conf：配置文件；
logs：日志文件；
webapps：webapp的默认部署目录；
work：工作目录；
temp：临时文件目录；
二、tomcat的配置文件：
server.xml：主配置文件；
context.xml：每个webapp都可以有专用的配置文件，这些配置文件通常位于webapp程序目录下的WEB-INF目录中，用于定义会话管理顺、JDBC等 ；conf/context.xml是为各webapp提供默认配置；
web.xml：每个webapp只有在“部署”之后才能够被访问；此文件则用于为各webapps定义默认的部署操作方式；
tomcat-users.xml：用户认证的账号和密码配置文件；
catalina.policy：当使用-security选项来启动tomcat实例时会读取此配置文件来实现基于安全策略的运行方式；
catalina.properties：Java属性的定义文件，用于设定类加载器路径等 ，以及一些与JVM性能相关的调优参数；
logging.properties：日志系统相关的配置；

三、tomcat的组件：
<Server>
<Service>
<connector/>
<connector/>
<Engine>
<Host />
<Host>
<Context/>
...
</Host>
</Engine>
</Service>
</Server>
每个组件，均有java类来实现；
此些组件可分为如下几类：
顶级组件：Server
服务类：Service
连接器：http, https, ajp(apache jserv protocol)
容器类：Engine, Host, Context
被嵌套的组件：valve, logger, realm, loader, manager
集群类组件：listener, ...
Java Webapp的组织结构：
有特定的组织形式、层次型的目录结构；主要包含了servlet代码文件、JSP页面文件、类文件、部署描述符文件等 ；
/：webapps的根目录
index.jsp：jsp的主页面文件
WEB-INF/：当前webapp的私有资源目录，通常存放当前webapp自用的web.xml；
META-INF/：当前webapp的私有资源目录，通常存储当前webapp自用的context.xml；
classes/: 当前webapp的私有类；
lib/：当前webapp的私有类，被打包成jar格式；
webapp归档格式：
.war：webapp
.jar：EJB的类；
.rar：资源适配器；
.ear：企业级应用程序；
