python, shell, golang获取本机IP地址

shell获取IP地址


/sbin/ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk '{print $2}'|tr -d "addr:"
/sbin/ifconfig|sed -n '/inet addr/s/^[^:]*:\([0-9.]\{7,15\}\) .*/\1/p' | grep -v 127.0.0.1

python获取IP地址
方法1：
def get_local_ip(ifname):  
    import socket, fcntl, struct  
    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("eth0")

方法2：
import  os
tmptxt=" /sbin/ifconfig eth0 |grep -w \"inet addr\" |cut -d: -f2 |cut -d\" \" -f1 "
IPTMP=os.popen(tmptxt).read()
IP=IPTMP.replace("\n","")
print IP
