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

Posted 2020-08-23

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：

 1 #!/usr/bin/python
 2 #encoding: utf-8
 3 
 4 from subprocess import Popen, PIPE
 5 
 6 p = Popen([‘dmidecode‘], stdout = PIPE)
 7 data = p.stdout
 8 lines = []
 9 dicts = {}
10 
11 while True:
12     line = data.readline()
13     if line.startswith(‘System Information‘):
14         while True:
15             line = data.readline()
16             if line == ‘\n‘:
17                 break
18             else:
19                 lines.append(line)
20         break
21 
22 d = dict([i.strip().split(‘:‘) for i in lines])
23 
24 #for k,v in dicts.items():
25 #    dicts[k] = v.strip()
26 dicts[‘Manufacturer‘] = d[‘Manufacturer‘].strip()
27 dicts[‘Product Name‘] = d[‘Product Name‘].strip()
28 dicts[‘Serial Number‘] = d[‘Serial Number‘].strip()
29 print dicts

 

方式2：

 1 #!/usr/bin/python
 2 #encoding: utf-8
 3 
 4 from subprocess import Popen, PIPE

 6 def getDmi():
 7     p = Popen([‘dmidecode‘], stdout = PIPE)
 8     data = p.stdout.read()
 9     return data
10 
11 def parseDmi(data):
12     lines = []
13     line_in = False
14     dmi_list = [i for i in data.split(‘\n‘) if i]
15     for line in dmi_list:
16         if line.startswith(‘System Information‘):
17             line_in = True
18             continue
19         if line_in:
20             if not line[0].strip():
21                 lines.append(line)
22             else:
23                 break
24     return lines
25 
26 def dimDic():
27     dmi_dic = {}
28     data = getDmi()
29     lines = parseDmi(data)
30     dic = dict([i.strip().split(‘: ‘) for i in lines])
31     dmi_dic[‘vendor‘] = dic[‘Manufacturer‘]
32     dmi_dic[‘product‘] = dic[‘Product Name‘]
33     dmi_dic[‘sn‘] = dic[‘Serial Number‘]
34 
35     return dmi_dic
36 
37 
38 if __name__ == ‘__main__‘:
39     print dimDic()
