使用 python 获取 Linux 系统信息(通过dmidecode命令)

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，更多的信息都可以通过这种方式去获取。

方式1：

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

from subprocess import Popen, PIPE

p = Popen(['dmidecode'], stdout = PIPE)
data = p.stdout
lines = []
dicts = {}

while True:
    line = data.readline()
    if line.startswith('System Information'):
        while True:
            line = data.readline()
            if line == '
':
                break
            else:
                lines.append(line)
        break

d = dict([i.strip().split(':') for i in lines])

#for k,v in dicts.items():
#    dicts[k] = v.strip()
dicts['Manufacturer'] = d['Manufacturer'].strip()
dicts['Product Name'] = d['Product Name'].strip()
dicts['Serial Number'] = d['Serial Number'].strip()
print dicts

方式2：

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

from subprocess import Popen, PIPE

def getDmi():
    p = Popen(['dmidecode'], stdout = PIPE)
    data = p.stdout.read()
    return data

def parseDmi(data):
    lines = []
    line_in = False
    dmi_list = [i for i in data.split('
') if i]
    for line in dmi_list:
        if line.startswith('System Information'):
            line_in = True
            continue
        if line_in:
            if not line[0].strip():
                lines.append(line)
            else:
                break
    return lines

def dimDic():
    dmi_dic = {}
    data = getDmi()
    lines = parseDmi(data)
    dic = dict([i.strip().split(': ') for i in lines])
    dmi_dic['vendor'] = dic['Manufacturer']
    dmi_dic['product'] = dic['Product Name']
    dmi_dic['sn'] = dic['Serial Number']

    return dmi_dic


if __name__ == '__main__':
    print dimDic()
