好使-利用python 下paramiko模块无密码登录

[root@salt-minion02 paramiko]# vim baoleiji4.py
# -*- coding:utf-8 -*-
import paramiko
private_key = paramiko.RSAKey.from_private_key_file('/root/.ssh/id_rsa')
# 创建SSH对象
ssh = paramiko.SSHClient()
# 允许连接不在know_hosts文件中的主机
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 连接服务器
ssh.connect(hostname="192.168.100.93",port=22,username="root",pkey=private_key)
# 执行命令
stdin,stdout,stderr = ssh.exec_command("df")
# 获取命令结果
result = stdout.read()
# 打印输出
print (result.decode())
ssh.close()

[root@salt-minion02 paramiko]# python3 baoleiji4.py
