Python实现获取Linux系统基本信息,获取信息如下:
主机名
系统版本
系统内核版本
总内存
CPU生厂商
CPU总核心数
服务器生厂商
服务器序列号
各网卡IP,MAC和网卡名信息
实现代码如下:
#!/usr/bin/python
#coding:utf8
from subprocess import Popen, PIPE
import re
#获取主机名,也可以使用 uname -n 命令获取
def hostname():
hostname = Popen(["hostname"], stdout=PIPE)
hostname = hostname.stdout.read()
return hostname
#获取操作系统版本
def osversion():
with open("/etc/RedHat-release") as f:
osversion = f.read()
return osversion
#获取操作系统内核版本
def oscoreversion():
oscoreversion = Popen(["uname", "-r"], stdout=PIPE)
oscoreversion = oscoreversion.stdout.read()
return oscoreversion
#获取CPU相关信息,如果存在多种不同CPU,那么CPU型号统计的为最后一种型号,这种情况少见
def cpuinfo():
corenumber = []
with open("/proc/cpuinfo") as cpuinfo:
for i in cpuinfo:
if i.startswith("processor"):
corenumber.append(i)
if i.startswith("model name"):
cpumode = i.split(":")[1]
return corenumber, cpumode #调用此函数需要用两个变量来接收参数
#获取内存相关信息
def meminfo():
with open("/proc/meminfo") as meminfo:
for i in meminfo:
if i.startswith("MemTotal"):
totalmem = i.split(":")[1]
return totalmem
#获取服务器硬件相关信息
def biosinfo():
biosinfo = Popen(["dmidecode", "-t", "system"], stdout=PIPE)
biosinfo = biosinfo.stdout.readlines()
for i in biosinfo:
if "Manufacturer" in i:
manufacturer = i.split(":")[1]
if "Serial Number" in i:
serialnumber = i.split(":")[1]
return manufacturer, serialnumber #调用此函数需要使用两个变量接收参数
#获取网卡信息,包括网卡名,IP地址,MAC地址
def ipaddrinfo():
#定义存储格式,以网卡名为key,mac地址和ip地址为一个列表,这个列表又为这网卡名的value
def add(dic, key, value):
dic.setdefault(key, [ ]).append(value)
ipinfo = Popen(["ip", "addr"], stdout=PIPE)
ipinfo = ipinfo.stdout.readlines()
dict1 = {}
for i in ipinfo:
if re.search(r"^\d", i):
devname = i.split(": ")[1]
continue
if re.findall("ether", i):
devmac = i.split()[1]
add(dict1, devname, devmac)
continue
if re.findall("global", i):
devip = i.split()[1]
add(dict1, devname, devip)
continue
return dict1
if __name__ == "__main__":
hostname = hostname()
osversion = osversion()
oscoreversion = oscoreversion()
totalmem = meminfo()
cpunumber, cpumode = cpuinfo()
manufacturer, serialnumber = biosinfo()
ipinfo = ipaddrinfo()
print("%s:\t\t %s" %("主机名", hostname)),
print("%s:\t %s" %("系统版本", osversion)),
print("%s:\t %s" %("系统内核版本", oscoreversion)),
print("%s:\t %s" %("总内存", totalmem)),
print("%s:\t%s" %("CPU生厂商", cpumode)),
print("%s:\t %s" %("CPU总核心数", len(cpunumber)))
print("%s:\t%s" %("服务器生厂商", manufacturer)),
print("%s:\t%s" %("服务器序列号", serialnumber)),
for x in ipinfo:
y = ipinfo.get(x)
ip = y[1]
mac = y[0]
print("%s%s:\t %s\t%s" %("网卡", x, ip, mac))
输出结果如下:
以上结果经CentOS 7和CentOS 6测试没有问题,其它系统使用可能会出现一些IO错误
