获取服务器IP地址，如果有公网地址就取公网地址，没有公网地址就取私网网址。
1，shell/ target=_blank class=infotextkey>shell脚本获取本地IP地址：
IP=`ifconfig | grep 'inet addr:' | cut -d: -f2 | grep -v ^10. | grep -v ^192.168 | grep -v ^172. |
grep -v ^127. | linuxjishu/13830.html target=_blank class=infotextkey>awk '{print $1}' | awk '{print;exit}'`
[ ! -n "$IP" ] && IP=`ifconfig | grep 'inet addr:' | cut -d: -f2 | grep -v ^127. |
awk '{print $1}' | awk '{print;exit}'`
2、python版：get_local_ip.py：
#!/usr/bin/env python
import socket
def Get_local_ip():
"""
Returns the actual ip of the local machine.
This code figures out what source address would be used if some traffic
were to be sent out to some well known address on the Internet. In this
case, a Google DNS server is used, but the specific address does not
matter much. No traffic is actually sent.
"""
try:
csock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
csock.connect(('8.8.8.8', 80))
(addr, port) = csock.getsockname()
csock.close()
return addr
except socket.error:
return "127.0.0.1"
if __name__ == "__main__":
local_IP = Get_local_ip()
print local_IP
3、有公网地址直接获取，没有公网地址就获取网关地址（用于判断IP地址的地理位置）：
get_public_ip.py
#!/usr/bin/env python
import re,urllib2
class Get_public_ip:
def getip(self):
try:
myip = self.visit("http://www.whereismyip.com/")
except:
try:
myip = self.visit("http://www.ip138.com/ip2city.asp")
except:
myip = "So sorry!!!"
return myip
def visit(self,url):
opener = urllib2.urlopen(url)
if url == opener.geturl():
str = opener.read()
return re.search('d+.d+.d+.d+',str).group(0)
if __name__ == "__main__":
getmyip = Get_public_ip()
print getmyip.getip()
4、判断服务器IP地理位置： get_ip_area.py
