1.## window10环境下jdk的安装与配置 （1）从官网下载jdk,地址：jdk1.8.0_101,官网链接地址https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html 如下图： 
（2）具体安装步骤打开后一直点击下一步安装完成即可，我安装的目录是c盘，安装过程略。 （3）下面主要是jdk的环境变量配置 3.1 系统变量——》新建JAVA_HOME变量 变量值是你jdk安装的目录，例如：C:\Program Files\Java\jdk1.8.0_101 
3.2 系统变量——》找到path变量，进行编辑添加%JAVA_HOME%\bin和%JAVA_HOME%\jre\bin 
3.3 系统变量——》新建CLASSPATH变量，变量值填写.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar注意前面有点分号 
3.4检验是否配置成功，win+r输入cmd,输入java -version，如图所示 显示版本信息 则说明安装和配置成功 
3.5 分别输入java和javac也会有内容输出 
以上配置好后就说明jdk的环境已经安装好了
1.下载Tomcat的压缩包，放在一个没有中文命名的路径下。百度云盘地址：https://pan.baidu.com/s/1SpQ1lmrnBBojezp5ioum-A 提取码：eoo7，或者到tomcat官网进行下载https://tomcat.apache.org/download-70.cgi 解压后如下： 
因为安装部署2个，将下载好的安装包复制了一份，分别命名如下： apache-tomcat-78080和apache-tomcat-78081 
2.下面主要是配置2个tomcat的环境 
2.1 分别创建变量，指向2个tomcat的解压目录，我装在D盘，如： 变量名CATALINA_BASE变量值D:\apache-tomcat-78080；变量名CATALINA_BASE2变量值D:\apache-tomcat-78081；变量名CATALINA_HOME变量值D:\apache-tomcat-78080；变量名CATALINA_HOME变量值D:\apache-tomcat-78081 2.2 
找到path变量，添加%CATALINA_HOME%\lib、%CATALINA_HOME%\bin、 %CATALINA_HOME2%\lib、%CATALINA_HOME2%\bin 这样2个tomcat的环境就配置好了。
3.配置好了还不能同时启动，端口号和启动服务都会冲突，导致其中一个tomcat启动失败，需要做如下改动： 8080tomcat的conf目录下的server.xml设置成
8081tomcat的conf目录下的server.xml设置成
8081的tomcat的bin目录下的startup.bat里面的%CATALINA_HOME%全部替换成%CATALINA_HOME2%，shutdown.bat里面的%CATALINA_HOME%也全部替换%CATALINA_HOME2%，8080的tomcat的bin目录下的startup.bat和shutdown.bat不动，文件里面内容的调整可以采用EditPlus工具打开。 startup.bat替换后的内容如下：

4.下面就可以启动了 
这样就完成本地同时启动2个tomcat了
