python实现多线程批量修改主机名代码实例讲解
最近在看多线程,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，能看得到的朋友，希望能有所收获。前提当然是这些服务器都做了统一的key......

# Description:
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(" ","")
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
