paramiko模块
paramiko是一个用于做远程控制的模块，使用该模块可以对远程服务器进行命令或文件操作，值得一说的是，fabric和ansible内部的远程管理就是使用的paramiko来现实。
下载安装
pip3 install paramiko
使用模块
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：
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='192.168.0.100', port=22, username='root', password='xxx')
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 获取命令结果
result = stdout.read()
print(result.decode('utf-8'))
# 关闭连接
ssh.close()
# SSHClient 封装 Transport
import paramiko
transport = paramiko.Transport(('192.168.0.100', 22))
transport.connect(username='root', password='xxx')
ssh = paramiko.SSHClient()
ssh._transport = transport
stdin, stdout, stderr = ssh.exec_command('df')
res=stdout.read()
print(res.decode('utf-8'))
transport.close()
- 基于公钥密钥连接
客户端文件名：id_rsa
服务端必须有文件名：authorized_keys(在用ssh-keygen时，必须制作一个authorized_keys,可以用ssh-copy-id来制作)
import paramiko
private_key = paramiko.RSAKey.from_private_key_file('/tmp/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='192.168.0.100', port=22, username='root', pkey=private_key)
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 获取命令结果
result = stdout.read()
print(result.decode('utf-8'))
# 关闭连接
ssh.close()
# SSHClient 封装 Transport
import paramiko
private_key = paramiko.RSAKey.from_private_key_file('/tmp/id_rsa')
transport = paramiko.Transport(('192.168.0.100', 22))
transport.connect(username='root', pkey=private_key)
ssh = paramiko.SSHClient()
ssh._transport = transport
stdin, stdout, stderr = ssh.exec_command('df')
result=stdout.read()
print(result.decode('utf-8'))
transport.close()
# 基于私钥字符串进行连接
import paramiko
from io import StringIO
key_str = """-----BEGIN RSA PRIVATE KEY-----
