dmidecode 是一个读取电脑 DMI（桌面管理接口(Desktop Management Interface)）表内容并且以人类可读的格式显示系统硬件信息的工具。（也有人说是读取 SMBIOS ——系统管理 BIOS(System Management BIOS)）  
这个表包含系统硬件组件的说明，也包含如序列号、制造商、发布日期以及 BIOS 修订版本号等其它有用的信息。  
DMI 表不仅描述了当前的系统构成，还可以报告可能的升级信息（比如可以支持的最快的 CPU 或者最大的内存容量）。  
这将有助于分析你的硬件兼容性，比如是否支持最新版本的程序。

### shell 方式获取 ###

dmidecode -t system
    dmidecode 2.12

内核在 /sys 目录下的文件中公开了一些 DMI 信息。因此，我们可以通过如下方式运行 grep 命令来轻易地获取机器类型。

grep “” /sys/class/dmi/id/\[pbs\]\*  
使用 cat 命令仅打印出特定的详细信息。

cat /sys/class/dmi/id/board\_vendor  
cat /sys/class/dmi/id/product\_name  
cat /sys/class/dmi/id/product\_serial  
cat /sys/class/dmi/id/bios\_version  
dmesg 命令是在 Linux 上 syslogd 或 klogd 启动前用来记录内核消息（启动阶段的消息）的。它通过读取内核的环形缓冲区来获取数据。在排查问题或只是尝试获取系统硬件信息时，dmesg 非常有用。

dmesg | grep -i DMI
    [root@zgl ~]# dmesg | grep -i DMI
    [ 0.000000] DMI: Inspur NF8460M4/NF8460M4, BIOS 4.2.17 01/28/2017

### golang 方式获取 ###

代码如下：

package main
     
    import (
    	"fmt"
    	"io/ioutil"
    	"strings"
    )
     
    type DMI struct {
    	BiosDate    string
    	BiosVendor  string
    	BiosVersion string
     
    	BoardAssetTag string
    	BoardName     string
    	BoardSerial   string
    	BoardVendor   string
    	BoardVersion  string
     
    	ChassisAssetTag string
    	ChassisSerial   string
    	ChassisType     string
    	ChassisVendor   string
    	ChassisVersion  string
     
    	ProductName    string
    	ProductSerial  string
    	ProductUuid    string
    	ProductVersion string
     
    	Modalias  string
    	SysVendor string
    	Uevent    string
    }
     
    var SysinfoDmi DMI

    	SysinfoDmi.Modalias = getStringFromFile("/sys/class/dmi/id/modalias")
    	SysinfoDmi.SysVendor = getStringFromFile("/sys/class/dmi/id/sys_vendor")
    	SysinfoDmi.Uevent = getStringFromFile("/sys/class/dmi/id/uevent")
     
    }
     
    func getStringFromFile(path string) string {
    	//读取文件全部内容
    	b, err := ioutil.ReadFile(path)
    	if err != nil {
    		return ""
    	}
    	return strings.Replace(string(b), "\n", "", -1)
    }
     
    func main() {
    	fmt.Println("#############bios info#############")
    	fmt.Println("bios_date:", SysinfoDmi.BiosDate)
    	fmt.Println("bios_vend:", SysinfoDmi.BiosVendor)
    	fmt.Println("bios_vers:", SysinfoDmi.BiosVersion)
    	fmt.Println("#############board info############")
    	fmt.Println("board_asset_tag:", SysinfoDmi.BoardAssetTag)
    	fmt.Println("board_name     :", SysinfoDmi.BoardName)
    	fmt.Println("board_serial   :", SysinfoDmi.BoardSerial)
    	fmt.Println("board_vendor   :", SysinfoDmi.BoardVendor)
    	fmt.Println("board_version  :", SysinfoDmi.BoardVersion)
     
    	fmt.Println("#############chassis info############")
