paramiko之ssh用法

import threading
import paramiko
import subprocess

def ssh_command(ip,user,passwd,command):
    client=paramiko.SSHClient()
    #client.load_host_keys("filename")使用密钥验证
    #设置自动添加和保存ssh服务器的ssh密钥
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(ip,username=user,password=passwd)
    ssh_session=client.get_transport().open_session()
    if ssh_session.active:
        #调用ssh_comand函数运行command
        ssh_session.exec_command(command)
        a=ssh_session.recv(1024)
    return a
a=ssh_command("192.168.6.128",'root','123456','ls -lh')
print(a.decode("gbk"))

基于用户名密码

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='c1.salt.com', port=22, username='wupeiqi', password='123')
  
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 获取命令结果
result = stdout.read()
  
# 关闭连接
ssh.close()

封装transport

import paramiko

transport = paramiko.Transport(('hostname', 22))
transport.connect(username='wupeiqi', password='123')

ssh = paramiko.SSHClient()
ssh._transport = transport

stdin, stdout, stderr = ssh.exec_command('df')
print stdout.read()

transport.close()

基于公钥密钥

import paramiko
 
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.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='c1.salt.com', port=22, username='wupeiqi', key=private_key)
 
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 获取命令结果
result = stdout.read()
 
# 关闭连接
ssh.close()

封装

import paramiko

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

transport = paramiko.Transport(('hostname', 22))
transport.connect(username='wupeiqi', pkey=private_key)

ssh = paramiko.SSHClient()
ssh._transport = transport

stdin, stdout, stderr = ssh.exec_command('df')

transport.close()

基于用户名密码上传下载

import paramiko
 
transport = paramiko.Transport(('hostname',22))
transport.connect(username='wupeiqi',password='123')
 
sftp = paramiko.SFTPClient.from_transport(transport)
# 将location.py 上传至服务器 /tmp/test.py
sftp.put('/tmp/location.py', '/tmp/test.py')
# 将remove_path 下载到本地 local_path
sftp.get('remove_path', 'local_path')
 
transport.close()

基于公钥密钥

import paramiko
 
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
 
transport = paramiko.Transport(('hostname', 22))
transport.connect(username='wupeiqi', pkey=private_key )
 
sftp = paramiko.SFTPClient.from_transport(transport)
# 将location.py 上传至服务器 /tmp/test.py
sftp.put('/tmp/location.py', '/tmp/test.py')
# 将remove_path 下载到本地 local_path
sftp.get('remove_path', 'local_path')
 
transport.close()

paramiko封装

class SshHelper(object):

    def __init__(self,host,port,username,pwd):
        self.host = host
        self.port = port
        self.username = username
        self.pwd = pwd
        self.transport = None

    def connect(self):
        transport = paramiko.Transport((self.host, self.port,))
        transport.connect(username=self.username, password=self.pwd)

    def upload(self,local,target):
        sftp = paramiko.SFTPClient.from_transport(self.transport)
        # 将location.py 上传至服务器 /tmp/test.py
        sftp.put(local, target)
        # 将remove_path 下载到本地 local_path
        # sftp.get('remove_path', 'local_path')

    def cmd(self,shell):
        ssh = paramiko.SSHClient()
        ssh._transport = self.transport
        stdin, stdout, stderr = ssh.exec_command(shell)
        stdout.read()

    def close(self):
        self.transport.close()
