一、堡垒机前戏

开发堡垒机之前，先来学习Python的paramiko模块，该模块机遇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=‘c1.salt.com‘, port=22, username=‘Jerry‘, password=‘123456‘)  # 执行命令stdin, stdout, stderr = ssh.exec_command(‘df‘)# 获取命令结果result = stdout.read()print(result.decode())# 关闭连接ssh.close()

import paramikotransport = paramiko.Transport((‘hostname‘, 22))transport.connect(username=‘Jerry‘, password=‘123456‘)ssh = paramiko.SSHClient()ssh._transport = transportstdin, stdout, stderr = ssh.exec_command(‘df‘)print stdout.read()transport.close()
SSHClient 封装 Transport

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=‘192.168.1.6‘, port=22, username=‘Jerry‘, pkey=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()

import paramikoprivate_key = paramiko.RSAKey.from_private_key_file(‘/home/auto/.ssh/id_rsa‘)transport = paramiko.Transport((‘hostname‘, 22))transport.connect(username=‘jerry‘, pkey=private_key)ssh = paramiko.SSHClient()ssh._transport = transportstdin, stdout, stderr = ssh.exec_command(‘df‘)transport.close()
SSHClient 封装 Transport

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=‘jerry‘,password=‘123456‘) sftp = paramiko.SFTPClient.from_transport(transport)# 将location.py 上传至服务器 /tmp/test.pysftp.put(‘/tmp/location.py‘, ‘/tmp/test.py‘)# 将remove_path 下载到本地 local_pathsftp.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=‘jerry‘, pkey=private_key ) sftp = paramiko.SFTPClient.from_transport(transport)# 将location.py 上传至服务器 /tmp/test.pysftp.put(‘/tmp/location.py‘, ‘/tmp/test.py‘)# 将remove_path 下载到本地 local_pathsftp.get(‘remove_path‘, ‘local_path‘) transport.close()
