Python paramiko使用方法代码汇总

import paramiko
paramiko.util.log_to_file('paramiko.log') # 记录日志文件
ssh = paramiko.SSHClient()
try:
  ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
  ssh.connect('139.xx.xx.xx', username='work', password='***')
  cmd = 'ls' # 需要执行的Linux命名
  stdin, stdout, stderr = ssh.exec_command(cmd) #执行命令后的结构
  print(stdout.readlines())
  print(stdout.read().decode())
except Exception as e:
  print("%s:%s" % (e.__class__, e))
finally:
  # 关闭
  ssh.close()

import paramiko
ssh = paramiko.SSHClient()
SSH_PRIVATE_KEY ='/Users/xueerhuan/.ssh/id_rsa' #本地密钥文件路径

try:
  key = paramiko.RSAKey.from_private_key_file(SSH_PRIVATE_KEY) # 无解密密码时
  #key = paramiko.RSAKey.from_private_key_file(SSH_PRIVATE_KEY, password='******') # 有解密密码时,

  ssh.load_system_host_keys() #通过known_hosts 方式进行认证可以用这个,如果known_hosts 文件未定义还需要定义 known_hosts
  #ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # 通过公共方式进行认证 (不需要在known_hosts 文件中存在)
  ssh.connect(hostname='139.XX.XX.XX', port=22, username='root', pkey=key)
  stdin, stdout, stderr = ssh.exec_command("ps")
  # 获取命令结果
  result = stdout.read()
  # 打印输出
  print(result.decode())
except Exception as e:
  print("%s:%s" % (e.__class__, e))
finally:
  # 关闭
  ssh.close()

The authenticity of host '192.168.1.42 (192.168.1.42)' can't be established.
ECDSA key fingerprint is SHA256:/ufx+/OLtdsYy7vsdk4KDu9xJsBp6zHonRAf2jjT0GI.
Are you sure you want to continue connecting (yes/no)? n^H
Please type 'yes' or 'no': yes
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
Password:

Number of key(s) added: 1

Now try logging into the machine, with:  "ssh 'morra@192.168.1.42'"  and check to make sure that only the key(s) you wanted were added.

#去目标机器下，检查authorized_keys文件
