##### 查看特定端口的占用情况（以80端口为例）

C:\Users\Administrator>netstat -aon|findstr 80
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4
TCP 0.0.0.0:8085 0.0.0.0:0 LISTENING 8044
TCP 127.0.0.1:7085 0.0.0.0:0 LISTENING 8044

UDP [fe80::557e:e741:6082:9989%4]:1900 : 716
UDP [fe80::557e:e741:6082:9989%4]:52839 : 716
UDP [fe80::e04c:f5c2:4a:3289%3]:1900 : 716
UDP [fe80::e04c:f5c2:4a:3289%3]:52838 : 716


在第2列可以找到，占用80端口的进程号为4。


#### 二. 用tasklist指令查找进程号对应的名称

从第2列找到进程号为4的，发现是System。


也可以在任务管理器查看进程对应的服务，发现pid=4的进程，其对应的进程描述是NT kernel & system。

#### 三. 遇到了“80端口被System占用”，该如何解决呢？


**这是什么进程？**  
 系统的80端口是被W3SVC（万维网发布服务，World Wide Web Publishing Service）占用了，它是系统提供http服务的依赖项。哪些服务使用了这个端口呢？


* World Wide Web：发布服务
* SSDP Discovery：局域网共享所需服务
* Print Spooler：打印机交互服务


**怎么处理呢？**  
 如果允许，可以直接不使用这个服务，这个进程显式停止是无法停止的，只有在cmd.exe里使用net stop http来停止。  
 (1) 关闭服务

C:\Users\Administrator>net stop http
下面的服务依赖于 HTTP Service 服务。
停止 HTTP Service 服务也会停止这些服务。
World Wide Web 发布服务
SSDP Discovery
Print Spooler
你想继续此操作吗? (Y/N) [N]: y
World Wide Web 发布服务服务正在停止.
World Wide Web 发布服务服务已成功停止。
SSDP Discovery 服务正在停止.
SSDP Discovery 服务已成功停止。
Print Spooler 服务正在停止.
Print Spooler 服务已成功停止。
HTTP Service 服务已成功停止。


或显示如下:  
 ![在这里插入图片描述](https://img-blog.csdnimg.cn/657ffd97a286477181ab215e66a2d132.png)  
 (2) 禁用服务

C:\Users\Administrator>sc config http start= disabled
[SC] ChangeServiceConfig 成功


此时查看可能发现80端口尚未释放,此时需重启服务器。  
 重启后,80单口端口就释放了。
