1、tomcatd的8080端口占用
问题： Several ports (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).
解决方法： 1、重启电脑 2、在cmd中查找占用8080端口的进程并终结它
$netstat -ano|findstr
8080
$taskkill /pid 端口号 /f
