可以通過命令

dmidecode -t 編碼

來獲取指定的硬件信息
例如獲取電源信息

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

Handle 0x0039, DMI type 39, 22 bytes

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
        -xml            output hardware tree as XML
        -json           output hardware tree as a JSON object
        -short          output hardware paths
        -businfo        output bus information

options can be
        -class CLASS    only show a certain class of hardware
        -C CLASS        same as '-class CLASS'
        -c CLASS        same as '-class CLASS'
        -disable TEST   disable a test (like pci, isapnp, cpuid, etc. )
        -enable TEST    enable a test (like pci, isapnp, cpuid, etc. )
        -quiet          don't display status
        -sanitize       sanitize output (remove sensitive information like serial numbers, etc.)
        -numeric        output numeric IDs (for PCI, USB, etc.)
        -notime         exclude volatile attributes (timestamps) from output

lshw > hardware.txt
會記錄所有硬件的相關(guān)信息
但可以使用其他命令查看
例如內(nèi)存相關(guān)可以使用lsmem和lshw中的顯示內(nèi)存部分是相同的
cpu可以使用lscpu查看文章來源地址http://www.zghlxwxcb.cn/news/detail-413219.html

到了這里，關(guān)于【Linux】查看服務器硬件信息的文章就介紹完了。如果您還想了解更多內(nèi)容，請在右上角搜索TOY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
