python的paramiko模块基本用法详解

pip install paramiko

import paramiko
# 创建 SSH 客户端
client = paramiko.SSHClient()
# 自动添加主机密钥 (不写这个可能会报错找不到主机)
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 连接到远程服务器
client.connect('your_host', username='your_username', password='your_password', allow_agent=False, look_for_keys=False)
# 参数说明：
# - hostname: 远程主机的IP地址或域名
# - username: 用于SSH连接的用户名
# - password: 用于SSH连接的密码
# - allow_agent: 是否允许使用代理验证，默认为False
# - look_for_keys: 是否在本地寻找私钥文件，默认为False
# 执行命令
stdin, stdout, stderr = client.exec_command('ls -l')
print(stdout.read().decode())
# 关闭连接
client.close()

import paramiko
# 创建 SSH 客户端
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect('your_host', username='your_username', password='your_password')
# 上传文件
sftp = client.open_sftp()
local_file_path = 'local_file.txt'
remote_file_path = '/path/on/remote/server/remote_file.txt'
sftp.put(local_file_path, remote_file_path)
# 下载文件
local_download_path = 'local_download.txt'
remote_download_path = '/path/on/remote/server/remote_file.txt'
sftp.get(remote_download_path, local_download_path)
# 关闭连接
sftp.close()
client.close()

import paramiko
# 创建 SSH 客户端
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 使用密钥认证
private_key_path = '/path/to/your/private/key'
key = paramiko.RSAKey(filename=private_key_path)
client.connect('your_host', username='your_username', pkey=key)
# 执行命令等操作
# 关闭连接
client.close()
