paramiko 实现ssh登录和sftp登录

import paramiko

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname=‘192.168.80.200‘,port=22,username=‘root‘,password=‘123‘)
stdin,stdout,stderr = ssh.exec_command(‘df;top‘)
res = stdout.read()+stderr.read()
print(res.decode())

#以下是密钥方式

import paramiko

private_key = paramiko.RSAKey.from_private_key_file("C:\\a\\a.rsa",‘123‘)    #没有密钥密码可以不用加“，‘123’”
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect(hostname=‘192.168.200.48‘,port=22,username=‘root‘,pkey=private_key)
stdin,stdout,stderr = ssh.exec_command(‘df;top‘)
res = stdout.read()+stderr.read()
print(res.decode())
