SSHClient

用于连接远程服务器并执行基本命令

基于用户名密码连接：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

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='c1.salt.com', port=22, username='wupeiqi', password='123')    # 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

 

transport = paramiko.Transport(('hostname', 22))

transport.connect(username='wupeiqi', password='123')

 

ssh = paramiko.SSHClient()

ssh._transport = transport

 

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

print stdout.read()

 

transport.close()

基于公钥密钥连接：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

import paramiko   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='c1.salt.com', port=22, username='wupeiqi', 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()

import paramiko

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

transport = paramiko.Transport(('hostname', 22))
transport.connect(username='wupeiqi', pkey=private_key)

ssh = paramiko.SSHClient()
ssh._transport = transport

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

transport.close()

SFTPClient

用于连接远程服务器并执行上传下载

基于用户名密码上传下载

1 2 3 4 5 6 7 8 9 10 11 12

import paramiko   transport = paramiko.Transport(('hostname',22)) transport.connect(username='wupeiqi',password='123')   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()

 

基于公钥密钥上传下载

1 2 3 4 5 6 7 8 9 10 11 12 13 14

import paramiko   private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')   transport = paramiko.Transport(('hostname', 22)) transport.connect(username='wupeiqi', 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()
