< 1.启动tomcat时候报错
Several ports (8005, 8080, 8009) required by Tomcat v7.0 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).
2.异常原因
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。
3.关闭占用端口软件就可以了
任务管理器–>详情信息–>javaw.exe右键关闭 -->重启eclipse中tomcat

4.查看pid的方法
