部署错误:Tomcat启动失败，服务器8080端口已被占用

问题描述

当我使用 Netbeans 运行 Java 项目时，出现以下错误:

When I run my Java project using Netbeans I get the following error:

Deployment error:
Starting of Tomcat failed, the server port 8080 is already in use.
See the server log for details.

我尝试将服务器端口更改为 8081 并在工具->服务器中关闭端口.它运行良好，但如果我执行任何操作并运行该项目，它会再次显示部署错误:Tomcat 启动失败，服务器端口 8081 已在使用中"

I tried changing the server port to 8081 and shutdown port in tool->server. It runs fine but again if I do any operations and run the project it says "Deployment error:Starting of Tomcat failed, the server port 8081 is already in use"

会有什么问题?

推荐答案

转到命令提示符

netstat -aon

Linux 版

netstat -tulpn | grep 'your_port_number'

它会告诉你类似的东西

 TCP    192.1.200.48:2053      24.43.246.60:443       ESTABLISHED     248
 TCP    192.1.200.48:2055      24.43.246.60:443       ESTABLISHED     248

 TCP    192.1.200.48:3976      192.1.200.11:49892     TIME_WAIT       0

 TCP    192.1.200.48:8080      209.85.153.100:80      ESTABLISHED     248

检查哪个进程绑定了您的端口.在上面的示例中，如果您确定需要终止该进程，那么现在它的 248

check which process has binded your port. here in above example its 248 now if you are sure that you need to kill that process fire

Linux:

kill -9 248

视窗:

taskkill /f /pid 248

它会杀死那个进程
