subject [CPyUG:54525] 远程tail -f功能的问题
  • 如何用python来实现远程tail -f的功能？ 各位有什么好的思路么？ 本地模拟tail -f功能可以这样： 

   1     file = open("access_log.2008061311","r")
   2     while 1:
   3         where = file.tell()
   4         content = file.readlines()
   5         if not content:
   6             time.sleep(1)
   7             file.seek(where)
   8         else:
   9             print content
  • 我初步想到的一个办法是把上面的代码放到B机器上运行，A机器起个监听程序，接收B机器返回的内容。但这样不够pythonic。有没有更加好的方法呢？

远程~paramiko模块

paramiko模块基本可以满足要求 

   1 import paramiko as ssh
   2 client=ssh.SSHClient()
   3 client.load_system_host_keys()
   4 client.connect(host,22,username,"",None,None)
   5 stdin, stdout, tderr = self.client.exec_command("tail -f log")
   6 line = stdout.readline()
   7 while line:
   8      #myTime = strftime('%H:%M:%S', localtime())
   9      print("[%s] %s" % (self.host,line))
  10      line = stdout.readline()
