Python多线程应用实例 使用多线程批量修改主机名

前面说到了python实现多线程，具体参见：https://www.ttlsa.com/python/python-multi-threaded-tutorial/

下面来举个例子来说明下:文章源自运维生存时间-https://www.ttlsa.com/python/python-multithreaded-applications-batch-change-the-host-name-to-use-multiple-threads/

新上的服务器初始化时，需要批量修改服务器主机名。文章源自运维生存时间-https://www.ttlsa.com/python/python-multithreaded-applications-batch-change-the-host-name-to-use-multiple-threads/

代码如下所示：文章源自运维生存时间-https://www.ttlsa.com/python/python-multithreaded-applications-batch-change-the-host-name-to-use-multiple-threads/

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()
