堡垒机
windows下安装python3的paramiko模块后一些报错总结:
- error: Unable to find vcvarsall.bat
[官网对此问题的描述] : https://docs.python.org/3.5/using/windows.html#compiling-python-on-windows
即官方推荐安装VS2015解决编译问题,或者安装MinGW解决,但都太麻烦
这里引用安装PyCrypto 第三方版解决,如下:
-
pip install --use-wheel --no-index --find-links=https://github.com/sfbahr/PyCrypto-Wheels/raw/master/pycrypto-2.6.1-cp35-none-win_amd64.whl pycrypto
-
然后再次安装paramiko,pip3 install paramiko
又报错如下:
“File "D:\Program Files\Python35\lib\site-packages\Crypto\Random\OSRNG\nt.py",line 28, in <module> import winrandom ImportError: No module named 'winrandom'”
- 修改python安装目录下D:\Program Files\Python35\Lib\site-packages\Crypto\Random\OSRNG\nt.py文件,将
import winrandom
改为from . import winrandom
,问题解决
开发堡垒机之前,先来学习Python的paramiko模块,该模块基于SSH用于连接远程服务器并执行相关操作
##### 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='192.168.1.82', port=22, username='ivan', 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()
SSHClient 封装 Transport
import paramiko
transport = paramiko.Transport(('hostname', 22))
transport.connect(username='ivan', password='123')
ssh = paramiko.SSHClient()
ssh._transport = transport
stdin, stdout, stderr = ssh.exec_command('df')
print stdout.read()
transport.close()
- 基于公钥密钥连接:
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='192.168.1.82', port=22, username='ma', 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()
SSHClient 封装 Transport
import paramiko
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
transport = paramiko.Transport(('hostname', 22))
transport.connect(username='ivan', pkey=private_key)
ssh = paramiko.SSHClient()
ssh._transport = transport
stdin, stdout, stderr = ssh.exec_command('df')
transport.close()
SFTPClient
用于连接远程服务器并执行上传下载
- 基于用户名密码上传下载
import paramiko
transport = paramiko.Transport(('hostname',22))
transport.connect(username='ivan',password='123')
sftp=paramiko.SFTPClient.from_transport(transport)
# 将F:\del\test_sftp.log 上传至服务器 /tmp/test_sftp.log
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()
- 基于公钥密钥上传下载
import paramiko
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
transport = paramiko.Transport(('hostname', 22))
transport.connect(username='ivan', 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()
