Python 通过dmidecode获取Linux服务器硬件信息

通过 dmidecode 命令可以获取到 Linux 系统的包括 BIOS、 CPU、内存等系统的硬件信息,这里使用 python 代码来通过调用 dmidecode 命令来获取 Linux 必要的系统信息

用法:

1、 dmidecode -t [类型代码或名称 ] 指令

(1)获取系统信息,例如:

sudo dmidecode -t 1
在这里插入图片描述
(2)获取主板信息:

sudo dmidecode -t 2
在这里插入图片描述
(3)获取CPU ID

sudo dmidecode -t 4 | grep ID

(4)获取系统序列号

sudo dmidecode | grep Serial

附:

dmidecode -t 指令参数参考

2、dmidecode -s [关键字] 指令

例如,查看处理器生产厂家:

sudo dmidecode -s processor-manufacturer

附可查询的关键字:

   bios-vendor, bios-version, bios-release-date,  
   system-manufacturer, system-product-name,system-version, system-serial-number,  system-uuid, 
   baseboard-manufacturer, baseboard-product-name, baseboard-version, baseboard-serial-number,  baseboard-asset-tag,
   chassis-manufacturer, chassis-type, chassis-version, chassis-serial-number, chassis-asset-tag, 
   processor-family, processor-manufacturer, processor-version,  processor-frequency

需要配置sudo免密:请参照 https://gaoming.blog.csdn.net/article/details/88993044
通过Python获取cpu id、主办序列号、内存数量

#!/usr/bin/python
# encoding: utf-8

import subprocess


def getCpuId():
    p = subprocess.Popen(["sudo dmidecode -t 4 | grep ID"], shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE , stderr=subprocess.PIPE)
    data = p.stdout
    lines = []
    while True:
        line = str(data.readline(), encoding="utf-8")
        if line == '\n':
            break
        if line:
            d = dict([line.strip().split(': ')])
            lines.append(d)
        else:
            break    
    return lines


def getBaseboardSerialnumber ():
    p = subprocess.Popen(["sudo dmidecode -t 2 | grep Serial"], shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE , stderr=subprocess.PIPE)
    data = p.stdout
    lines = []
    while True:
        line = str(data.readline(), encoding="utf-8")
        if line == '\n':
            break
        if line:
            d = dict([line.strip().split(': ')])
            lines.append(d)
        else:
            break    
    return lines


def memory ():
    p = subprocess.Popen(["sudo dmidecode -t memory | grep 'Number Of Devices'"], shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE , stderr=subprocess.PIPE)
    data = str(p.stdout.read(), encoding="utf-8")
    d = dict([data.strip().split(': ')])
    return d


if __name__ == '__main__':
    print (getCpuId())
    print (getBaseboardSerialnumber())
    print (memory())
