python paramiko 执行命令

在node1上想对node2执行命令，标准的答案

1.比较直观

#!/usr/bin/env python 

import paramiko   

hostname='192.168.0.102'  

username='root'  

password='abc'   

port=22     

paramiko.util.log_to_file('paramiko.log')          

s=paramiko.SSHClient()                 

s.set_missing_host_key_policy(paramiko.AutoAddPolicy())          

s.connect(hostname = hostname,port=port,username=username, password=password)          

stdin,stdout,stderr=s.exec_command('free;df -h')          

print stdout.read()

2.类的形式

#!/usr/bin/python

# coding=utf8

import paramiko,datetime,os,threading

#class run_cmd(threading.Thread):

class run_cmd():

      def __init__(self,hostname=None,password=None,username=None,port=None,echo_cmd=None):

          #threading.Thread.__init__(self)

          self.hostname=hostname

          self.password=password

          self.username=username

          self.port=port

          self.echo_cmd=echo_cmd

          #self.thread_stop=False

      def run(self):

          paramiko.util.log_to_file('paramiko.log')

          s=paramiko.SSHClient()

          s.set_missing_host_key_policy(paramiko.AutoAddPolicy())

          s.connect(hostname = self.hostname,username=self.username, password=self.password)

          stdin,stdout,stderr=s.exec_command(self.echo_cmd)

          return stdout.read()

          s.close()

      def stop(self):

           self.thread_stop=True

if __name__=='__main__':

    f = file('/home/python/filelist1','r')

    port=22

    c = f.readlines()

    for x in c:

        hostname = x.split('::')[0]

        password = x.split('::')[1]

        username = x.split('::')[2]    

        remote = x.split('::')[4].strip('\n')

        echo_cmd='/bin/find  %s -maxdepth 1 -type d -mmin -1200' %(remote)

        #echo_cmd='free;df -h'

        cmd_thread=run_cmd(hostname,password,username,port,echo_cmd)

        result=cmd_thread.run()

        print result

    f.close()

如果运行有错误，请参考python 增量同步远程文件夹

2.Python 利用pexpect和paramiko模块进行远程服务器的监控
