Paramiko模块

安装：

pip3 install paramiko

示例：

import paramiko

# 创建ssh对象
ssh = paramiko.SSHClient()

# 允许连接不在know_host文件中的主机
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 连接服务器
ssh.connect(hostname='39.107.24.78',port=22,username='root',password='123456')

# 执行命令
stdin,stdout,stderr = ssh.exec_command('hostname')

# 获取命令结果
result = stdout.read()

# 关闭连接
ssh.close()

print(result.decode('utf-8'))

### 使用秘钥连接
# 获取私钥
private_key = paramiko.RSAKey.from_private_key_file(r'/Users/liuguixiang/.ssh/id_rsa')

ssh.connect(hostname='39.107.24.78',port=22,username='root',pkey=private_key)

import paramiko
from io import StringIO

#私钥
key = """

示例二(上传下载文件)：

import paramiko

transport = paramiko.Transport(('39.107.24.78',22))
transport.connect(username='root',password='123456')
sftp = paramiko.SFTPClient.from_transport(transport)

# 上传
sftp.put('a.txt','/data/a.txt')

# 下载
sftp.get('/data/a.txt','b.txt')

transport.close()
