Several ports (8005, 8080, 8009) required by Tomcat v6.0 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).
查看端口没有被占用 netstat -ano
解决办法：
1、运行cmd进入命令行界面；
2、运行命令： netsh winsock reset
3、重启电脑
在运行tomcat，可以正常启动。
