python--paramiko模块

sftp传送文件：

import paramiko

transport = paramiko.Transport(('localhost',22))
transport.connect(username='guqing',password='sina4433')

sftp = paramiko.SFTPClient.from_transport(transport)
#将location.py上传至服务器/guqing/home/lib
sftp.put('/home/guqing/para/lib','/home/guqing/lib')  #source,remote
#将远程文件下载至本地/home/guqing/test/lib
sftp.get('/home/guqing/lib','/home/guqing/test/lib')  #remote,local

transport.close()

 ssh:

import paramiko
#创建SSH对象
ssh = paramiko.SSHClient()
#允许连接不再know_hosts文件中的主机
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
#连接服务器
ssh.connect(hostname='localhost',port=22,username='guqing',password='sina4433')
#执行命令
stdin,stdout,stderr = ssh.exec_command('df')
res,err = stdout.read(),stderr.read()
result = res if res else err

print(result.decode())
ssh.close()

基于秘钥之sftp:

import paramiko



private_key = paramiko.RSAKey.from_private_key_file('/home/guqing/.ssh/id_rsa')


transport = paramiko.Transport(('localhost',22))   #remote_host
transport.connect(username='guqing',pkey=private_key)

sftp = paramiko.SFTPClient.from_transport(transport)
#将location.py上传至服务器/guqing/home/lib
sftp.put('/home/guqing/para/lib','/home/guqing/lib')  #source,remote
#将远程文件下载至本地/home/guqing/test/lib
sftp.get('/home/guqing/lib','/home/guqing/test/lib')  #remote,local

transport.close()

基于秘钥之ssh:

import paramiko

#ssh-copy-id "-p22 guqing@10.0.0.31"   #复制本地用户公钥至远程主机

private_key = paramiko.RSAKey.from_private_key_file('/home/guqing/.ssh/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='localhost',port=22,username='guqing',pkey=private_key)


stdin,stdout,stderr = ssh.exec_command('df')
res,err = stdout.read(),stderr.read()
result = res if res else err

print(result.decode())
ssh.close()
