paramiko

paramiko

是使用Python语言写的一个模块，遵循SSH2协议，支持以加密和认证的方式远程连接服务器。

paramiko有两个模块：

SSHClient   执行命令

SFTPClient  上传下载文件

paramiko官方文档

 

SSHClient，SFTPClient都可以基于 Transport进行封装， 因此可以将 SSHClient和SFTPClient都封装到同一个类中。

SSHClient（执行命令）

SSHClient执行命令

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='192.168.12.59', port=22, username='root', password='sungaohui1990')

# 执行命令
stdin, stdout, stderr = ssh.exec_command('ls /')
# 获取命令结果
result = stdout.read()
print(result)

# 关闭连接
ssh.close()

 通过Transport将 SSHClient进行封装

import paramiko

transport = paramiko.Transport(("10.120.4.90", 22))
transport.connect(username="ims", password="Easyt0use@admin1")

ssh = paramiko.SSHClient()
ssh._transport = transport
stdin, stdout, stderr = ssh.exec_command("df -HP")
print(str(stdout.read(), encoding="utf-8"))
transport.close()

 基于rsa秘钥的 SSHClient

import paramiko


key = paramiko.RSAKey.from_private_key_file("D:\\id_rsa")

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname="10.120.4.90", port=22, username="root", pkey=key)
stdin, stdout, stderr = ssh.exec_command("df -HP")
print(str(stdout.read(), encoding="utf-8"))
ssh.close()

 基于RSA字符串的 SSHClient

import paramiko
from io import StringIO

key_str = """-----BEGIN RSA PRIVATE KEY-----

基于私钥字符串进行连接

 

SFTPClient（上传下载文件）

import paramiko

key = paramiko.RSAKey.from_private_key_file("D:\\id_rsa")

transport = paramiko.Transport(("10.120.4.90", 22))
transport.connect(username="root", pkey=key)

sftp = paramiko.SFTPClient.from_transport(transport)
sftp.put("paramiko_01.py", "/tmp/abc.py")
sftp.get("/tmp/Identity.pub", "Identity.pub")
sftp.close()
