Tomcat:Several ports (8005, 8080, 8009)
启动Tomcat时：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：8080端口被占用，或者是已经启动了Tomcat的Eclipse非正常的关闭。
解决方法：
在命令窗口中，
输入 netstat -ano|findstr 8080 ：（查看占用了8080端口的进程）
taskkill /pid XXXX（占用8080的端口） /f ：（结束占用了8080端口的进程）
最后重启Tomcat，看看是否能够启动成功
