# 怎么查看WINDOWS端口被哪个程序占用

DOS下命令：\
`netstat -a -n` 各个端口占用\
`netstat -ano` 各个端口占用和进程PID

## 假如我们需要确定谁占用了我们的80端口

在windows命令行窗口下执行：

```
C:\>netstat -aon|findstr "80"
协议    本地地址                     外部地址               状态                   PID
TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       1648
TCP    0.0.0.0:81             0.0.0.0:0              LISTENING       1716
```

看到了吗，端口被进程号为1648的进程占用，继续执行下面命令：

```
C:\>tasklist|findstr "1648"
映像名称                       PID 会话名              会话#       内存使用
 ========================= ======== ================
Apache.exe                   1648 Console                 0      6,496 K
```

很显然Apache占用了你的端口。结束该进程：

```
C:\>taskkill /f /t /im Apache.exe
```
