paramiko远程连接以及批量远程连接

paramiko是什么? 基于ssh用于连接远程服务器做操作:远程执行命令， 上传文件， 下载文件

import paramiko
#ssh root@172.25.254.250
创建一个ssh对象;
client = paramiko.SSHClient()
2. 解决问题:如果之前没有；连接过的ip, 会出现
#Are you sure you want to continue connecting (yes/no)? yes
自动选择yes
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())3. 连接服务器
client.connect(hostname='172.25.254.1',username='root',password='westos'
)
4. 执行操作
stdin, stdout, stderr = client.exec_command('hostname')
5. 获取命令的执行结果;
print(stdout.read().decode('utf-8'))
6. 关闭连接
client.close()

批量连接
