错误记录--报tomcat端口号方法，Several ports (8005, 8080, 8009) required by Tomcat

启动Tomcat服务器报错：

Several ports (8005, 8080, 8009) required by Tomcat v5.5 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).

原因：端口8005, 8080, 8009被占用了。可能是在打开Tomcat的情况下关闭了Eclipse，或是Eclipse非正常关闭，导致先前的Tomcat没有被关闭，端口占用。或是其他软件占用了tomcat的端口号。 

解决方法：重启电脑
