linxu 使用dmidecode命令，查看服務器硬件信息（包括維保序列號）

公司linux系統服務器業務通常都在外地，若是某時想知道，服務器的CPU、主板，內存型號或者bios信息怎麼辦？除了到機房或者重啓服務器按delete進入bios查看，還

 

有沒有更好的辦法？答案是確定的，有！不須要到機房、不須要重啓進入bios。使用dmidecode 命令便可查看服務器一些硬件信息和bios信息。配置使用方法以下：

 

Dmidecode簡介

DMI (Desktop Management Interface, DMI)就是幫助收集電腦系統信息的管理系統，DMI信息的收集必須在嚴格遵守SMBIOS規範的前提下進行。 SMBIOS(System Management BIOS)

 

是主板或系統製造者以標準格式顯示產品管理信息所需遵循的統一規範。SMBIOS和DMI是由行業指導機構Desktop Management Task Force (DMTF)起草的開放性的技術標準，其中

 

DMI設計適用於任何的平臺和操做系統。

 

1.軟件安裝

 

#查看軟件包是否安裝

 

rpm -qa|grep dmidecode

dmidecode-2.11-2.el6.x86_64

 

 

#若是沒有安裝，使用下面命令安裝；

yum install -y dmidecode

 

#參數

-d, --dev-mem FILE Read memory from device FILE (default: /dev/mem)

從設備文件讀信息，輸出內容與不加參數標準輸出相同

-h, --help Display this help text and exit

顯示幫助信息

-q, --quiet Less verbose output

顯示更少的簡化信息

-s, --string KEYWORD Only display the value of the given DMI string

只顯示指定DMI字符串的信息

-t, --type TYPE Only display the entries of given type

只顯示指定條目的信息

-u, --dump Do not decode the entries

顯示未解碼的原始條目內容

--dump-bin FILE Dump the DMI data to a binary file

--from-dump FILE Read the DMI data from a binary file

-V, --version Display the version and exit

顯示版本信息
