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_type     : 10
    chassis_serial   : 
    chassis_vendor   : Dell Inc.
    chassis_version  :
