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 == '\n':
                 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('\n') 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()
