paramikoparamiko是一个用于做远程控制的模块,使用该模块可以对远程服务器进行命令或文件操作,值得一说的是,fabric和ansible内部的远程管理就是使用的paramiko来现实。
安装pip install paramiko
模块使用
执行命令—用户名+密码
#!/usr/bin/env python
#coding:utf-8
import paramiko
# 建立一个sshclient对象
ssh = paramiko.SSHClient()
# 允许将信任的主机自动加入到host_allow 列表,此方法必须放在connect方法的前面
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 调用connect方法连接服务器
ssh.connect('192.168.1.108', 22, 'alex', '123')
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 结果放到stdout中,如果有错误将放到stderr中
print(stdout.read().decode('utf-8'))
# 关闭连接
ssh.close();

paramiko 2.4.2 依赖 cryptography,而最新的cryptography==2.5里有一些弃用的API。
解决删掉cryptography,安装2.4.2,就不会报错了。
执行命令 -秘钥pip uninstall cryptography
pip install cryptography==2.4.2
import paramiko
private_key_path = '/home/auto/.ssh/id_rsa'
key = paramiko.RSAKey.from_private_key_file(private_key_path)
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('主机名 ', 端口, '用户名', key)
stdin, stdout, stderr = ssh.exec_command('df')
print(stdout.read().decode("utf-8"))
ssh.close()
