python的paramiko模块

 

SSHClient

用于连接远程服务器并执行基本命令

基于用户名密码连接：

第一种方法

import paramiko
# 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='192.168.1.10', port=22, username='root', password='123')
  
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 获取命令结果
result = stdout.read()
  
# 关闭连接
ssh.close()

第二种方法 SSHClient封装了Transport

import paramiko  
  
transport = paramiko.Transport(('**.**.**.**', 22))  
transport.connect(username='***', password='********')  
  
ssh = paramiko.SSHClient()  
ssh._transport = transport  
  
stdin, stdout, stderr = ssh.exec_command('df')  
print (stdout.read().decode('utf-8'))  
  
transport.close()  

输出：

Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/sda1       19609276 3081820  15531360  17% /
udev              498496       4    498492   1% /dev
tmpfs             203104     808    202296   1% /run
none                5120       0      5120   0% /run/lock
none              507756     200    507556   1% /run/shm

 

 

基于公钥密钥连接：

 

 

通过在linux命令窗口 输入ssh-keygen 得到公钥私钥对 并存放于不同文件中（通过创建过程可知），并将.pub结尾的公钥内容添加到你所需要登陆的 地址用户 authorized_keys中，通常是 .ssh/authorized_keys 

或者可以通过ssh-copy-id "-p52113 root@10.0.0.31" 自动追加至对方文件中

windows通过密钥连接Ubuntu时要注意：

1.拷贝ssh-keygen生成的密钥至程序运行目录

2. .ssh/authorized_keys 中的authorized_keys文件权限必须为600 没有则自己创建

 

ubuntu连接ubuntu：将本机生成的公钥内容追加至远程主机的authorized_keys中

 

 

第一种方法

import paramiko
 
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.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='192.168.1.10', port=22, username='root', key=private_key)
 
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 获取命令结果
result = stdout.read()
 
# 关闭连接
ssh.close()

第二种方法 SSHClient封装了Transport

import paramiko

private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')

transport = paramiko.Transport(('192.168.1.10', 22))
transport.connect(username='root', pkey=private_key)

ssh = paramiko.SSHClient()
ssh._transport = transport

stdin, stdout, stderr = ssh.exec_command('df')

transport.close()

第三种 基于私钥字符串进行连接

from io import StringIO

key_str = """-----BEGIN RSA PRIVATE KEY-----
