1、以apache-tomcat-7.0.6为例，进入tomcat安装目录，编辑文件“安装目录\apache-tomcat-7.0.6\conf\server.xml”（可以用记事本打开）
2、在server.xml文件中依次查找并修改端口号：<Server port=争犸禀淫"8005" shutdown="SHUTDOWN"媪青怍牙><Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/><Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
3、在server.xml文件中依次查找修改<Server port="8005" shutdown="SHUTDOWN">修改为：<Server port="8006" shutdown="SHUTDOWN">
4、<Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/>修改为：<Connector port="8010" protocol="AJP/1.3" redirectPort="8444"/>
5、<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>修改为：<Connector connectionTimeout="20000" port="8081" protocol="HTTP/1.1" redirectPort="8444"/>
6、启动tomcat，访问http://localhost:8081/ ；能成功访问，说明修改成功（访问的端口跟据配置文件中设置的Connector 端口）
