Linux获取DMI信息

Linux下获取硬件基础信息，比如生产厂商、系统、机箱等等，直接在目录/sys/class/dmi/id/下读取即可，可以使用命令dmidecode:

kongs@BJ-DZ0101277:/$ dmidecode --help
Usage: dmidecode [OPTIONS]
Options are:
 -d, --dev-mem FILE     Read memory from device FILE (default: /dev/mem)
 -h, --help             Display this help text and exit
 -q, --quiet            Less verbose output
 -s, --string KEYWORD   Only display the value of the given DMI string
 -t, --type TYPE        Only display the entries of given type
 -u, --dump             Do not decode the entries
     --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

也可直接使用代码：

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

func init() {
	//bios
	SysinfoDmi.BiosDate = getStringFromFile("/sys/class/dmi/id/bios_date")
	SysinfoDmi.BiosVendor = getStringFromFile("/sys/class/dmi/id/bios_vendor")
	SysinfoDmi.BiosVersion = getStringFromFile("/sys/class/dmi/id/bios_version")
	//board
	SysinfoDmi.BoardAssetTag = getStringFromFile("/sys/class/dmi/id/board_asset_tag")
	SysinfoDmi.BoardName = getStringFromFile("/sys/class/dmi/id/board_name")
	SysinfoDmi.BoardSerial = getStringFromFile("/sys/class/dmi/id/board_serial")
	SysinfoDmi.BoardVendor = getStringFromFile("/sys/class/dmi/id/board_vendor")
	SysinfoDmi.BoardVersion = getStringFromFile("/sys/class/dmi/id/board_version")
	//chassis
	SysinfoDmi.ChassisAssetTag = getStringFromFile("/sys/class/dmi/id/chassis_asset_tag")
	SysinfoDmi.ChassisSerial = getStringFromFile("/sys/class/dmi/id/chassis_serial")
	SysinfoDmi.ChassisType = getStringFromFile("/sys/class/dmi/id/chassis_type")
	SysinfoDmi.ChassisVendor = getStringFromFile("/sys/class/dmi/id/chassis_vendor")
	SysinfoDmi.ChassisVersion = getStringFromFile("/sys/class/dmi/id/chassis_version")

	SysinfoDmi.ProductName = getStringFromFile("/sys/class/dmi/id/product_name")
	SysinfoDmi.ProductSerial = getStringFromFile("/sys/class/dmi/id/product_serial")
	SysinfoDmi.ProductUuid = getStringFromFile("/sys/class/dmi/id/product_uuid")
	SysinfoDmi.ProductVersion = getStringFromFile("/sys/class/dmi/id/product_version")

	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############")
	fmt.Println("chassis_asset_tag:", SysinfoDmi.ChassisAssetTag)
	fmt.Println("chassis_type     :", SysinfoDmi.ChassisType)
	fmt.Println("chassis_serial   :", SysinfoDmi.ChassisSerial)
	fmt.Println("chassis_vendor   :", SysinfoDmi.ChassisVendor)
	fmt.Println("chassis_version  :", SysinfoDmi.ChassisVersion)

	fmt.Println("#############product info############")
	fmt.Println("product_name   :", SysinfoDmi.ProductName)
	fmt.Println("product_serial :", SysinfoDmi.ProductSerial)
	fmt.Println("product_uuid   :", SysinfoDmi.ProductUuid)
	fmt.Println("product_version:", SysinfoDmi.ProductVersion)

	fmt.Println("#############other   info############")
	fmt.Println("Modalias :", SysinfoDmi.Modalias)
	fmt.Println("SysVendor:", SysinfoDmi.SysVendor)
	fmt.Println("Uevent   :", SysinfoDmi.Uevent)
	fmt.Println("bay")

	// fmt.Printf("%+v\n", SysinfoDmi)
}

执行结果：

chassis_asset_tag: 
chassis_type     : 10
chassis_serial   : 
chassis_vendor   : Dell Inc.
chassis_version  : 
#############product info############
product_name   : Latitude 5280
product_serial : 
product_uuid   :
