在eclipse中tomcat提示8080端口被占用

错误信息是：Port 8080 required by J2EE Preview at localhost is 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).

我在安装tomcat时已经设端口为24000，为什么还是提示8080被占用？

在启动tomcat应该选择上面的那个，选择下面的就会出现修改了端口号，依然会监听8080端口。
