如何创建python脚本以进行ssh并在多个linux设备上运行命令

import paramiko

ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect(hostname='目标设备IP', username='用户名', password='密码')

stdin, stdout, stderr = ssh.exec_command('要执行的命令')

output = stdout.read().decode('utf-8')

ssh.close()

import paramiko

def run_command_on_device(ip, username, password, command):
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(hostname=ip, username=username, password=password)
    stdin, stdout, stderr = ssh.exec_command(command)
    output = stdout.read().decode('utf-8')
    ssh.close()
    return output

# 示例用法
ip_list = ['192.168.1.1', '192.168.1.2', '192.168.1.3']
username = 'your_username'
password = 'your_password'
command = 'ls -l'

for ip in ip_list:
    output = run_command_on_device(ip, username, password, command)
    print(f"设备 {ip} 的命令执行结果：\n{output}")
