使用Paramiko库ssh远程主机

安装

pip install paramiko

基于用户名密码的连接

import paramiko


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())

ssh.connect(<host>, 22, <username>, <password>)

stdin, stdout, stderr = ssh.exec_command('hostname')
for line in stdout:
    print(line.replace('\n', ''))
for line in stderr:
    print(line.replace('\n', ''))

stdin, stdout, stderr = ssh.exec_command('id')
for line in stdout:
    print(line.replace('\n', ''))
for line in stderr:
    print(line.replace('\n', ''))

ssh.close()

基于公钥密钥的连接

import paramiko


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

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())

ssh.connect(hostname=<host>, port=22, username=<username>, pkey=private_key)

stdin, stdout, stderr = ssh.exec_command('hostname')
for line in stdout:
    print(line.replace('\n', ''))
for line in stderr:
    print(line.replace('\n', ''))

stdin, stdout, stderr = ssh.exec_command('id')
for line in stdout:
    print(line.replace('\n', ''))
for line in stderr:
    print(line.replace('\n', ''))

ssh.close()
