linxu 使用dmidecode命令,查看服务器硬件信息(包括维保序列号)

公司linux系统服务器业务一般都在外地,如果某时想知道,服务器的CPU、主板,内存型号或者bios信息怎么办?除了到机房或者重启服务器按delete进入bios查看,还

 
有没有更好的办法?答案是肯定的,有!不需要到机房、不需要重启进入bios。使用dmidecode 命令即可查看服务器一些硬件信息和bios信息。配置使用方法如下:
 
Dmidecode简介
DMI (Desktop Management Interface, DMI)就是帮助收集电脑系统信息的管理系统,DMI信息的收集必须在严格遵照SMBIOS规范的前提下进行。 SMBIOS(System Management BIOS)
 
是主板或系统制造者以标准格式显示产品管理信息所需遵循的统一规范。SMBIOS和DMI是由行业指导机构Desktop Management Task Force (DMTF)起草的开放性的技术标准,其中
 
DMI设计适用于任何的平台和操作系统。
 
1.软件安装
 
#查看软件包是否安装
 
rpm -qa|grep dmidecode
dmidecode-2.11-2.el6.x86_64
 
 
#如果没有安装,使用下面命令安装;
yum install -y dmidecode
 
#参数
-d, --dev-mem FILE Read memory from device FILE (default: /dev/mem)
从设备文件读信息,输出内容与不加参数标准输出相同
-h, --help Display this help text and exit
显示帮助信息
-q, --quiet Less verbose output
显示更少的简化信息
-s, --string KEYWORD Only display the value of the given DMI string
只显示指定DMI字符串的信息
-t, --type TYPE Only display the entries of given type
只显示指定条目的信息
-u, --dump Do not decode the entries
显示未解码的原始条目内容
--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
显示版本信息
