同一伺服器部署多個tomcat時，存在埠號衝突的問題，所以需要修改tomcat配置檔案server.xml，以tomcat7為例。

• 首先了解下tomcat的幾個主要埠：

<Connector port="8080" protocol="HTTP/1.1"  connectionTimeout="60000"  redirectPort="8443" disableUploadTimeout="false"  executor="tomcatThreadPool" URIEncoding="UTF-8"/>

其中8080為HTTP埠，8443為HTTPS埠

<Server port="8005" shutdown="SHUTDOWN">   

8005為遠端停服務埠

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> 

8009為AJP埠，APACHE能過AJP協議訪問TOMCAT的8009埠。

• 部署多個tomcat主要修改三個埠：

1. <Connectorport="8081"protocol="HTTP/1.1"
2.                connectionTimeout="60000"
3.                redirectPort="8443"disableUploadTimeout
   ="false"executor="tomcatThreadPool"URIEncoding="UTF-8"/>

<Connector port="8081" protocol="HTTP/1.1" 
               connectionTimeout="60000" 
               redirectPort="8443" disableUploadTimeout="false"  executor="tomcatThreadPool"  URIEncoding="UTF-8"/>

2.遠端停服務埠，預設8005，如下改為8006

1. <Serverport="8006"shutdown="SHUTDOWN">......  

<Server port="8006" shutdown="SHUTDOWN">......

3.AJP埠，預設8009，如下改,8010

1. <Connectorport="8010"protocol="AJP/1.3"redirectPort="8443"/>
