在linux下获得ip地址可以使用ifconfig指令
[root@zhu ~]# ifconfig eth0 |grep 'inet addr' | awk -F '[: ]+' '{print $4}'
192.168.56.101[root@zhu ~]# ifconfig eth0 |grep 'inet addr' | cut -d: -f2 | cut -d' ' -f1 192.168.56.101
[root@zhu ~]# ifconfig eth0 |grep 'inet addr' | cut -d: -f2 | awk '{print $1}'
192.168.56.101在python中获得ip地址的方法如下
[root@zhu ~]# python zhu.py
192.168.56.101
10.0.3.15
[root@zhu ~]# cat zhu.py
#!/usr/bin/python
import socket,fcntl,struct
def get_local_ip(ifname = 'eth0'):
s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
inet = fcntl.ioctl(s.fileno(), 0x8915, struct.pack('256s', ifname[:15]))
ret = socket.inet_ntoa(inet[20:24])
return ret
print get_local_ip()
print get_local_ip('eth1')[root@zhu ~]# python zhu.py
192.168.56.101
[root@zhu ~]# cat zhu.py
#!/usr/bin/python
import subprocess
import re
regu = re.compile('\\d+\.\\d+\.\\d+\.\\d+')
p = subprocess.Popen('ifconfig eth0',shell=True,stdout=subprocess.PIPE)
print regu.findall(p.stdout.read())[0]
