tomcat报错，提示Several ports (8005, 8080, 8009) required by Tomcat v8.5 Server at localhost are already

eclipse运行web项目报错提示：

Several ports (8005, 8080, 8009) required by Tomcat v8.5 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).

报错原因是：端口被占用的问题。

出现错误的主要原因就是：在tomcat启动的时候，直接关闭eclipse，就会导致端口被占用。

两种解决方法：

第一种方法非常简单，但是必须知道tomcat的安装路径在哪里。

（1）在tomcat的目录下，找到bin文件夹里面的shutdown.bat执行一下，再去eclipse里面启动tomcat就成功了！
