一台机器同时运行两个或多个Tomcat

今天经理交给我一个任务，让我在服务器上再装一个测试用的tomcat，因为我们的系统中有用到调用移动CMPP短信接口给客户发短信的功能，限制了IP，只能在服务器上调试。没辙，以前也想过在自己的机器上同时跑两个tomcat，以为只要改一下端口号就没问题，其实这只是其中的一步而已。

当第一个tomcat启动后，后面tomcat的server.xml中的端口不管怎么改，仍然会报端口冲突。后来在dos下运行才发现所有的tomcat都会去找

CATALINA_HOME和CATALINA_BASE这两个环境变量，因此步骤如下： 
1.使用压缩版的tomcat不能使用安装版的。 
2.第一个tomcat的配置不变。 
3.增加环境变量CATALINA_HOME2，值为新的tomcat的地址；增加环境变量CATALINA_BASE2，值为新的tomcat的地址。 
4.修改新的tomcat中的startup.bat，把其中的CATALINA_HOME改为CATALINA_HOME2。 
5.修改新的tomcat中的catalina.bat，把其中的CATALINA_HOME改为CATALINA_HOME2，CATALINA_BASE改为CATALINA_BASE2。 
6.修改conf/server.xml文件： 
6.1 <Server port="8005" shutdown="SHUTDOWN">把端口改为没有是使用的端口。 
6.2 <Connector port="8080" maxHttpHeaderSize="8192" 
  maxThreads="150" minSpareThreads="25" maxSpareThreads="75" 
  enableLookups="false" redirectPort="8443" acceptCount="100" 
  connectionTimeout="20000" disableUploadTimeout="true" /> 把端口改为没有是使用的端口。 
6.3<Connector port="8009" 
  enableLookups="false" redirectPort="8443" protocol="AJP/1.3" /> 把端口改为没有是使用的端口。 
7成功！

下面是我配置好的server.xml
