阿里云Centos6.5 部署多个Tomcat 实例。

前景提要：

为了实现服务器使用效率最大化，有必要配置两个tomcat在一个或多个服务器中。下面介绍在同一个服务器配置两个Tomcat的过程。

详细步骤讲解：

1、拷贝原来的Tomcat到另外一个目录，并且重新命名     如：tomcat1

2、修改Tomcat1中的server.xml文件，把shutdown和Connector端口修改成另外的数值，如8006/8081

以下是我修改后的相关文件：

3、修改startup.sh和shutdown.sh文件，在第一行加入：
export CATALINA_HOME=/usr/local/tomcat1

以下是相关配置文件：

shutdown.sh
