简单利用python批量修改主机名

最近初始化服务器时正好需要批量修改一组甚至几组服务器的主机名,写一个简单的脚本试试

前提当然是这些服务器都做了统一的key......

import re
import os,sys,datetime
import threading

class ThreadClass(threading.Thread):
  def run(self):
    now = datetime.datetime.now()
    print "%s over at time %s" % (self.getName(),now)


f = file('hostadd','r')
for line in f.readlines():
  ip = re.findall('\d+\.\d+\.\d+\.\d+',line)[0]
  host = line[15:].replace("\n","")
  cmd = "hostname %s && sed -i 's/HOSTNAME=.*/HOSTNAME=\%s/g' /etc/sysconfig/network" % (host,host)
  process = os.popen('ssh %s ' % ip + "%s" % cmd).read()
  print process
  t = ThreadClass()
  t.start()

hostadd 文件内容为：

192.168.76.132 node1.example.com
192.168.76.133 node2.example.com
