paramiko模塊是基於Python實現的SSH遠程安全連接，用於SSH遠程執行命令、文件傳輸等功能。

安裝方法

paramiko模塊不是python自帶的標準庫，執行pip install paramiko進行安裝。如果pip未配置，請參考<python工具安裝和pip工具配置>完成配置。

使用方法

1、在遠程服務器執行指定命令

import paramiko

def ssh_con(ip, username, password):
    try:
        con = paramiko.SSHClient()
        con.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        con.connect(ip
 
=ip, username=username, password=password, timeout=5)
    except:
        return None
    else:
        return con

def exec_cmd(conn, cmd):
    interact = conn.invoke_shell()
    interact.send(cmd)
    result = interact.recv(65535)
    return result
    
def exec_cmd2(conn,cmd):
    stdin, stdout, stderr 
 
= conn.exec_command(cmd)
    channel = stdout.channel
    ret = channel.recv_exit_status()
    if ret == 0:
        return (ret, stdout.read())
    else:
        return (ret, stderr.read())

if __name__ == ‘__main__‘:
    ip = ‘192.168.0.1‘
    user = ‘root‘
    passwd = ‘root‘
    con = ssh_con(ip, user, passwd)
    
 
if not con:
        print "Connect %s fail,please check." % (ip,)
    cmd = ‘df -k‘
    ret, result = exec_cmd2(con,cmd)
    print result
