• python远程批量执行命令


    #!/usr/bin/env python

    from multiprocessing import Process,Pool
    import time,paramiko,sys,os
    host_list = (
      ('16.74.185.167','root','123456','df -Th'),

    s = paramiko.SSHClient() #绑定实例
    s.load_system_host_keys() #加载本机.ssh/knows_host文件

      for line in cmd_result:
        print line,

    p = Pool(processes=1) #1表示单进程,根据cpu核数定,一般是几个核就写几 
    result_list = []

    for h in host_list:
       result_list.append(p.apply_async(ssh_run, [h,]))

    for res in result_list:
      res.get()

    s.close()

    命令已经写死

    高级版:自定义命令显示结果并手动退出

    result_list = []
    q='quit'
    e='exit'

    #------通过输入来判断------

    while True:
      input_cmd = raw_input("please input command:").strip()
      if input_cmd == q or input_cmd == e:
        break
      else:

        for res in result_list:

    s.close()
