1. dmidecode 是解析/dev/mem 获取硬件信息
2. 容器(docker)内无法使用/dev/mem ,因此需要挂载/dev/mem
3. 容器(docker)无法使用dmidecode,在这里有2种解决办法，
   a. 挂载/sbin/dmidecode 到docker内
   b.docker 安装dmidecode ,yum install -y dmidecode
4. 运行

docker run -it --privileged -v /dev/mem:/dev/mem -v /sbin/dmidecode:/sbin/dmidecode 5d0da3dc9764

[root@7a94b5a3b51b /]# dmidecode -s system-serial-number

	// 获取系统id
	cmdPid := exec.Command("/bin/sh", "-c", `dmidecode -t processor | grep 'ID' | awk -F ':' '{print $2}' | head -n 1`)

	if err != nil {
