import paramiko

 # 创建SSH对象

 ssh = paramiko.SSHClient()

 # 允许连接不在know_hosts文件中的主机

 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

 # 连接服务器

 ssh.connect(hostname='x.x.x.x', port=, username='xiaoli, password='')

 # 执行命令

 stdin, stdout, stderr = ssh.exec_command('df')

 # 获取命令结果

 result = stdout.read()

 # 关闭连接

 ssh.close()

 import paramiko

 # 创建transport对象

 transport = paramiko.Transport(('x.x.x.x', ))

 transport.connect(username='xiaoli', password='')

 ssh = paramiko.SSHClient()

 ssh._transport = transport

 stdin, stdout, stderr = ssh.exec_command('df')

 print stdout.read()

 transport.close()

 跟密码连接差不多，只是密码的地方变成了私钥

 import paramiko

 #私钥路径

 private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')

 # 创建SSH对象

 ssh = paramiko.SSHClient()

 # 允许连接不在know_hosts文件中的主机

 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

 # 连接服务器

 ssh.connect(hostname='x.x.x.x, port=22, username='xiaoli, key=private_key)

 # 执行命令

 stdin, stdout, stderr = ssh.exec_command('df')

 # 获取命令结果

 result = stdout.read()

 # 关闭连接

 ssh.close()

 同理，跟上边的差不多

 import paramiko

 private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')

 transport = paramiko.Transport(('x.x.x.x', ))

 transport.connect(username='xiaoli', pkey=private_key)

 ssh = paramiko.SSHClient()

 ssh._transport = transport

 stdin, stdout, stderr = ssh.exec_command('df')

 transport.close()

 简单小例

 import paramiko

 transport = paramiko.Transport(('x.x.x.x',))

 transport.connect(username='xiaoli',password='')

 sftp = paramiko.SFTPClient.from_transport(transport)

 # 将location.py 上传至服务器 /tmp/test.py

 sftp.put('/tmp/location.py', '/tmp/test.py')

 # 将remove_path 下载到本地 local_path

 sftp.get('remove_path', 'local_path')

 transport.close()

 import paramiko

 private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')

 transport = paramiko.Transport(('x.x.x.x.', ))

 transport.connect(username='xiaoli', pkey=private_key )

 sftp = paramiko.SFTPClient.from_transport(transport)

 # 将location.py 上传至服务器 /tmp/test.py

 sftp.put('/tmp/location.py', '/tmp/test.py')

 # 将remove_path 下载到本地 local_path

 sftp.get('remove_path', 'local_path')

 transport.close()
