最近在筆記本重新安裝了虛擬機，由於在家在公司經常需要切換IP，修改IP配置文件，覺得挺繁瑣的，所以就索性的寫了一個自動切換IP的腳本，主要是讀配置文件修改，詳情如下：
1、創建配置文件：
# cat ip.conf [home] ip = 192.168.7.150 gateway = 192.168.7.1 [work] ip = 10.7.93.150 gateway = 10.7.93.1
2、腳本實例
#!/usr/bin/env python
# conding = utf-8
# finame swtch_ip.py
# This is swtch ip python file
import socket,os,sys
import ConfigParser
import time
from optparse import OptionParser
def init():
global IPS
global GATEWAYS
config = ConfigParser.ConfigParser()
dir = os.path.dirname(os.path.abspath(__file__))
conf = dir + "/conf"
filepath = "%s/ip.conf" %(conf)
if not os.path.exists(filepath):
raise "ERROR: ip.conf is not it!"
config.read(filepath)
IPS = config.get(options.type,"ip")
GATEWAYS = config.get(options.type,"gateway")
print "======[%s] Start get new options,please wait... ======" %(options.type)
print "%s config file ip is %s,gateway is %s" %(options.type,IPS,GATEWAYS)
def getopts():
MSG_USAGE='''python %s -t home''' % sys.argv[0]
optParser=OptionParser(MSG_USAGE)
optParser.add_option('-t',action='store',type='string',dest='type',default='work',help=u'type:work,home')
(options,args)=optParser.parse_args()
return options
def ipconfig():
ipconfigfile = open('/etc/sysconfig/network-scripts/ifcfg-eth0','r')
while True:
ipconfiglines = ipconfigfile.readlines()
if not ipconfiglines:
break
#ipconfigfile.close()
if "IPADDR" in ipconfiglines[4] and "GATEWAY" in ipconfiglines[3]:
print "====== Change IP and GATEWAY, please wait... ======"
temp = ipconfiglines[4].split('\"')
a = temp[1]
temp1 = ipconfiglines[3].split('\"')
b = temp1[1]
print "ifcfg-et0 config old IP is %s and old GATEWAY is %s" %(a,b)
edit_file = os.system('sed -i "s/'+a+'/'+IPS+'/g;s/'+b+'/'+GATEWAYS+'/g" /etc/sysconfig/network-scripts/ifcfg-eth0')
if edit_file == 0:
print 'Edit ifcfg-eth0 ip and gateway is OK,restart network restart'
restart_network = os.system('/etc/init.d/network restart')
if restart_network == 0:
print "Network restart Succ!"
else:
print "Network restart Fail!"
else:
print 'Edit ifcfg-eth0 ip is ERROR'
else:
print "no IP address and GATEWAY!!!"
if __name__ == '__main__':
if len(sys.argv)<1 and sys.argv[1] != '-h' and sys.argv[1] != '--help':
print '''Usage: python %s -t work
python %s -h|--help''' % (sys.argv[0],sys.argv[0])
sys.exit(1)
options = getopts()
init()
ipconfig()3、查看幫助
# python swich_ip.py --help Usage: python swich_ip.py -t home Options: -h, --help show this help message and exit -t TYPE type:work,home
4、運行測試
# python swich_ip.py -t home ======[home] Start get new options,please wait... ====== home config file ip is 192.168.7.250,gateway is 192.168.7.1 ====== Change IP and GATEWAY, please wait... ====== ifcfg-et0 config old IP is 192.168.7.250 and old GATEWAY is 192.168.7.1 Edit ifcfg-eth0 ip and gateway is OK,restart network restart 正在關閉接口 eth0： [確定] 關閉環回接口： [確定] 彈出環回接口： [確定] 彈出界面 eth0： [確定] Network restart Succ!
5、結果
# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE="eth0" ONBOOT="yes" BOOTPROTO="static" GATEWAY="192.168.7.1" IPADDR="192.168.7.250"
