解决CentOS系统使用lspci命令查看PCI设备（Command not found）方法

原因

• 是因为CentOS系统最小化安装之后，相应的软件包没有进行安装。

• 需要手动去安装之后再使用lspci命令

解决办法

1. 在终端内执行下面的命令

   yum whatprovides */lspci

2. 得到如下回应
   

3. 继续复制下面的命令粘贴到终端内

   yum install pciutils

4. 中间提示的时候输入 y 确认
   

5. 然后你就可以使用lscpi命令了

6. 下面是完整的操作命令过程

   [root@localhost ~]# lspci -v
   -bash: lspci: 未找到命令
   [root@localhost ~]# yum whatprovides */lspci
