（1）首先安裝paramiko庫
pip?install?paramiko
（2）封裝了以下類，可以直接拿來使用
import?paramiko class?SSHClient(object): ????def?__init__(self,host,username,password,port=22): ????????self.__host=host ????????self.__username=username ????????self.__password=password ????????self.__port=port ????????self.__ssh=None ????????self.connect() ????def?__del__(self): ????????self.close() ????def?connect(self): ????????self.__ssh?=?paramiko.SSHClient() ????????self.__ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ????????self.__ssh.connect(hostname=self.__host,port=self.__port,username=self.__username,password=self.__password) ????def?exec(self,cmd): ????????print(f"begin?to?run?remote?cmd:?{cmd}") ????????stdin,?stdout,?stderr?=?self.__ssh.exec_command(cmd,timeout=1800) ????????returncode?=?stdout.channel.recv_exit_status() ????????output=stdout.read().decode('utf-8') ????????return?output ????def?close(self): ????????self.__ssh.close()
（3）比如準備一個ip地址為192.168.1.12的linux虛擬機，然后直接按照如下方法使用上面封裝的類即可實現(xiàn)遠程執(zhí)行linux命令
ssh=SSHClient(host="192.168.1.12",username="root",password="xxxxxx") output=ssh.exec("ifconfig") print(output)
（4）執(zhí)行結果如下
