這篇文章主要介紹了Python通過(guò)paramiko庫(kù)實(shí)現(xiàn)遠(yuǎn)程執(zhí)行l(wèi)inux命令,本文給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

（1）首先安裝paramiko庫(kù)

pip install paramiko

（2）封裝了以下類，可以直接拿來(lái)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(zhǔn)備一個(gè)ip地址為192.168.1.12的linux虛擬機(jī)，然后直接按照如下方法使用上面封裝的類即可實(shí)現(xiàn)遠(yuǎn)程執(zhí)行l(wèi)inux命令

ssh=SSHClient(host="192.168.1.12",username="root",password="xxxxxx")
output=ssh.exec("ifconfig")
print(output)

（4）執(zhí)行結(jié)果如下

begin to run remote cmd: ifconfig
