【Linux】查看服务器硬件信息

本文介绍: 如果电源是双电源，则会显示两组一样的信息。和lsh w中的显示内存部分是相同的。会记录所有硬件的相关信息。但可以使用其他命令查看。来获取指定的硬件信息。例如内存相关可以使用。

查看 服务器 硬件信息

dmidecode

例如 查看 电源信息

$ dmidecode &gt; /tmp/hardware.log
$ grep -ni "system power" /tmp/hardware.log

可以通过命令

dmidecode -t 编码

来获取指定的硬件信息
例如获取电源信息

$ /usr/sbin/dmidecode -t 39
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.2.0 present.

使用lshw

# lshw --help
Hardware Lister (lshw) - 
usage: lshw [-format] [-options ...]
       lshw -version

        -version        print program version ()

format can be
        -html           output hardware tree as HTML
