关于解压官网下载:apache-tomcat-6.0.45.zip
解压后展现目录:
主要关注bin,conf,webapps这三个目录;bin目录里面会有启动的,停止的bat文件,conf主要是tomcat的配置文件,webapps主要是项目的发布文件,在webapps下,tomcat有自己的目录和文件
运行时,调用startup.bat文件:

① 首先会根据web.xml文件提供的顺序穿件一个Catalina的servlet容器调用自己带的监听器,会监听程序的运行:
② 寻找CATALINA_HOME这个tomcat的环境变量,因为现在版本的tomcat放在一个叫Catalina的容器里,以前的tomcat的环境变量为TOMCAT_HOME,如果没有就将当前目录赋予为CATALINA_HOME这个目录,然后执行设置该目录为他运行的根目录
③ 在根目录下寻找catalina.bat文件并通过JAVA_HOME和JRE_HOME连接上JVM,该文件里面内容如下:

④ 在加载文件的时候,需要访问setclasspath.bat文件;来寻早到java的路径,如果没有配置JAVA_HOME和JAR_HOME环境变量,可以在路径寻找之前用set JAVA_HOME=”jdk所在路径”来设置访问路径。文件如下:

⑤ 在里这CATALINA_HOME文件夹下面的.bat文件加载完毕后,会加载conf下面catalina.properties文件,根据该配置文件的顺序,执行里面的server.xml调用项目的配置文件和tomcat-users.xml检查调用权限。
关于使用tomcat发布项目的四种方式:
- 直接把项目复制到Tomcat安装目录的webapps目录中,这是最简单的一种Tomcat项目部署的方法,也是初学者最常用的方法。
- 在tomcat安装目录中有一个conf文件夹,打开此文件夹,其中包含配置文件server.xml,打开配置文件,并在和之间插入如下语句。
其中,docBase为设置项目的路径。 - 在tomcat安装目录下的conf目录下面,打开server.xml文件,在标签之间,添加
<Service name="culture"> <Connector port="6011" maxHttpHeaderSize="8906" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="utf-8" useBodyEncodingForURI="true" /> <Engine name="culture" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase" /> <Host name="localhost" appBase=""> <Context path="" docBase="E:\ZRPDWorkspaces\MyEclipse Professional 2014\finance_culture\WebRoot" debug="5" reloadable="true" crossContext="true"> <Resource name="jdbc/itfin" auth="Container"type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="root" password="bigdata@mysql" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://192.168.1.197:3306/culture?autoReconnect=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull"/> Context> Host> Engine> Service>

4.在conf目录中,在Catalina\localhost(此处需要注意目录的大小写)目录下新建一个XML文件,任意命名,只要和当前文件中的文件名不重复即可,代码如下。
第四种方法相对来说比较灵活,并且可以设置别名。该目录下面自身有两个tomcat容器的xml文件;
