Python之路第十二天，高级(6)-paramiko

paramiko

一、安装

pip3 install paramiko

二、使用

SSHClient

用于连接远程服务器并执行基本命令

1. 基于用户和密码链接

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='192.168.224.136', port=22, username='zhangxunan', password='123456') # 执行命令 stdin, stdout, stderr = ssh.exec_command('ls') # 获取命令结果 result = stdout.read().decode() print(result) # 关闭连接 ssh.close()

SSHClient封装transport

import paramiko transport = paramiko.Transport(('192.168.224.136', 22)) transport.connect(username='zhangxunan', password='123456') ssh = paramiko.SSHClient() ssh._transport = transport stdin, stdout, stderr = ssh.exec_command('df') print(stdout.read().decode()) transport.close()

基于公钥密钥连接：

import paramiko private_key = paramiko.RSAKey.from_private_key_file('/home/zhangxunan/.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='192.168.224.137', port=22, username='zhangxunan', key=private_key) # 执行命令 stdin, stdout, stderr = ssh.exec_command('df') # 获取命令结果 result = stdout.read().decode() # 关闭连接 ssh.close()

SSHClient封装transport

import paramiko private_key = paramiko.RSAKey.from_private_key_file('/home/zhangxunan/.ssh/id_rsa') transport = paramiko.Transport(('hostname', 22)) transport.connect(username='zhangxunan', 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(('192.168.224.136',22)) transport.connect(username='zhangxunan',password='123456') 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()

基于公钥密钥上传下载：

import paramiko private_key = paramiko.RSAKey.from_private_key_file('/home/zhangxunan/.ssh/id_rsa') transport = paramiko.Transport(('192.168.224.137', 22)) transport.connect(username='zhangxunan', 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()

例子：

多线程执行批量主机执行命令

import threading import paramiko class Anstack(object): def __init__(self,host,cmd): #host为变量 self.host = host self.cmd = cmd self.port = 22 self.username = 'root' self.pwd = '123456' self.run() def run(self): #执行方法 self.connect() self._cmd() self.close() def connect(self): #链接方法 transport = paramiko.Transport((self.host,self.port)) transport.connect(username=self.username,password=self.pwd) self.__transport = transport def close(self): #关闭方法 self.__transport.close() def _cmd(self): ssh = paramiko.SSHClient() ssh._transport = self.__transport # 执行命令 stdin, stdout, stderr = ssh.exec_command(self.cmd) # 获取命令结果 result = stdout.read() print(result) if __name__ == '__main__': args = ['192.168.1.1','192.168.1.2','192.168.1.3','192.168.1.4'] cmd = input('您要执行的命令') for i in args: Execcmd = threading.Thread(target=Anstack, args=(i,cmd,)) Execcmd.start()
