Linux怎么查看硬件信息之lshw命令

lshw工具简介

本文主要介绍lshw命令,该命令是Linux系统管理中较为常用的一个命令行工具,用于查看硬件信息。多数Linux发行版默认情况下并没有集成该工具,本文将会讲解如何利用lshw命令查看服务器硬件信息。

安装工具:
CentOS7.6为例:

[root@zcwyou ~]# yum -y install lshw

Linux安装lshw

1. 查看网卡信息

命令:

[root@zcwyou ~]# lshw  -C network

输出信息:

3. 查看CPU信息

不需要使用lshw命令

[root@zcwyou ~]# cat /proc/cpuinfo |more

输出结果:
