在Linux系统中,有许多命令可用于查询主机的硬件信息。一些命令只针对特定的硬件组件,比如CPU、内存,一些命令可以查询多个硬件信息。 这篇文章只是简单的让每个人了解查询硬件信息的基本命令使用,包括lscpu、hwinfo、lshw、lspci、lsblk、lsusb等等。 1. lscpu用于查询CPU信息03 | CPU op -mode(s): 32-bit, 64-bit |
04 | Byte Order: Little Endian |
11 | Vendor ID: GenuineIntel |
18 | Virtualization type : full |
2. lshw显示硬件信息表这个命令应用普遍,它可通过个人需求而列出多种不同的硬件参数:CPU、内存、硬盘、USB控制器、lshw卡片等等,本质上就是从/proc目录不同文件中中提取对应的硬件信息。 按照下面的步骤去安装lshw工具,然后就可以使用了。 1 | wget http://ezix.org/software/files/lshw-B.02.14. tar .gz |

3. hwinfo-硬件信息hwinfo类似于lshw,也能查询硬件信息,且应用广泛。它也能输出多个硬件部分的详细或者简要信息,但是不同的是有时hwinfo比lshw的信息更详细。 默认情况下,Linux系统没有安装hwinfo工具,所以你需要按照以下步骤自己安装: CentOS 6 CentOS 5 02 | Retrieving http://mirror.symnds.com/distributions/gf/el/6/gf/x86_64/gf-release-6-6.gf.el6.noarch.rpm |
