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。Eclipse非正常关闭，导致先前的Tomcat没有被关闭。
杀掉占用端口的软件
打开任务管理器，结束javaw.exe
