0.下载：
从官网上下载最新版的TOMCAT: http://tomcat.apache.org/download-60.cgi 找到相应的版本。
根据电脑系统版本，我下载的是apache-tomcat-8.0.20-windows-x86.zip
解压直接放到D盘下，目录为apache-tomcat-8.0.20
1.运行：
找到D:apache-tomcat-8.0.20in下的startup.bat 一闪即过，看不到相关的内容。
用CMD来查看相关的信息提示：
Microsoft Windows [版本 6.1.7600]

C:UsersAN>d:
D:>cd apache-tomcat-8.0.20in
D:apache-tomcat-8.0.20in>startup.bat
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program
D:apache-tomcat-8.0.20in>
以前电脑上已经安装好了JDK,并配置相关的环境变量。
2.配置：
右键计算机--》属性----》高级系统设置---》进入环境变量
在系统变量中，新建一下项目
变量名： 对应变量值：
JAVA_HOME C:Program FilesJavajdk1.8.0_31
JRE_HOME C:Program FilesJavajre1.8.0_31
3.运行检测：
在次用CMD来查看相关的信息提示：

然后正常显示TOMCAT运行窗口：

至此，java JDK和Tomcat环境配置完成
配置完成以后想确定是否配置成功，以下步骤
1检验java JDK是否配置成功
进入控制台 输入java 如果出现"java"不是内部或外部命令，也不是可运行的程序或批处理文件，说明没有配置成功。反之如果出现java相关的东西则说明成功。
2.检验Tomcat是否配置成功
进入到Tomcat的bin目录下，找到startup.bat，双击运行，如果一散而过，则可能未配置成功（进一步确定,在网页地址栏输入localhost:8080或者127.0.0.1:8080，若没有反应则表示没有配置成功），反之则配置成功
关闭是shutdown.bat
启动出错，可以进入相应的目录后，用catalina run来查看具体的报错，
