linux怎么查看硬件型号?

如何在Linux/centos下查看网卡型号，如何查看主板型号，CPU/显卡信息，硬盘型号等硬件信息

查看网卡型号

[root@www.ctohome.com]# lspci | grep Ethernet

00:19.0 Ethernet controller: Intel Corporation 82567V-2 Gigabit Network Connection

查看内存和cpu最直接最常用的命令：

[root@www.ctohome.com]# free

Swap: 5124692 0 5124692

[root@www.ctohome.com]# cat /proc/cpuinfo

查看硬盘信息(查看硬盘型号和硬盘序列号)：

[root@www.ctohome.com]# df -h
