Several ports (8005, 8081) required by Tomcat v9.0 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.

解决方案：

1.打开控制台（win+r）输入“netstat -ano”，得到下图

 

 

复制端口号对应的PID,打开服务进程（Ctrl+x）选择任务管理

 

 

找到对应的PID结束进程（鼠标右键）就可以了

 

2.直接修改tomcat的端口号：run->Edit Configuration
