paramiko是一個(gè)用于做遠(yuǎn)程控制的模塊，使用該模塊可以對(duì)遠(yuǎn)程服務(wù)器進(jìn)行命令或文件操作，值得一說(shuō)的是，fabric和ansible內(nèi)部的遠(yuǎn)程管理就是使用的paramiko來(lái)現(xiàn)實(shí)。

安裝

pip install paramiko

執(zhí)行命令—用戶名+密碼

#!/usr/bin/env python
#coding:utf-8
import paramiko
# 建立一個(gè)sshclient對(duì)象
ssh = paramiko.SSHClient()
# 允許將信任的主機(jī)自動(dòng)加入到host_allow 列表，此方法必須放在connect方法的前面
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 調(diào)用connect方法連接服務(wù)器
ssh.connect('192.168.1.108', 22, 'alex', '123')
# 執(zhí)行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 結(jié)果放到stdout中，如果有錯(cuò)誤將放到stderr中
print(stdout.read().decode('utf-8'))
# 關(guān)閉連接
ssh.close();

原因

paramiko 2.4.2 依賴 cryptography，而最新的cryptography==2.5里有一些棄用的API。

解決

刪掉cryptography，安裝2.4.2，就不會(huì)報(bào)錯(cuò)了。

pip uninstall cryptography

pip install cryptography==2.4.2

執(zhí)行命令 -秘鑰

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('主機(jī)名 ', 端口, '用戶名', key)
stdin, stdout, stderr = ssh.exec_command('df')
print(stdout.read().decode("utf-8"))
ssh.close()
