（1）首先安装paramiko库
pip install paramiko
（2）封装了以下类，可以直接拿来使用
import paramikoclass 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）比如准备一个ip地址为192.168.1.12的linux虚拟机，然后直接按照如下方法使用上面封装的类即可实现远程执行linux命令
v0.dev

ssh=SSHClient(host="192.168.1.12",username="root",password="xxxxxx")output=ssh.exec("ifconfig")print(output)
（4）执行结果如下
begin to run remote cmd: ifconfigens33: flags=4163 mtu 1500 inet 192.168.1.12 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 240e:3a1:da7:6590:b39f:e15:6b3d:7e7 prefixlen 64 scopeid 0x0 inet6 fe80::4a67:131d:9133:acdf prefixlen 64 scopeid 0x20 ether 00:0c:29:58:d8:4c txqueuelen 1000 (Ethernet) RX packets 195340 bytes 148862388 (141.9 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 163425 bytes 20837281 (19.8 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 32 bytes 2592 (2.5 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 32 bytes 2592 (2.5 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0virbr0: flags=4099 mtu 1500 inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255 ether 52:54:00:e8:3f:5c txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
