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('192.168.0.114', port=22, username='test', password='123456')

# 执行命令
stdin, stdout, stderr = ssh.exec_command('ls -ltr /etc')
# 获取命令结果
res, err = stdout.read(), stderr.read()
result = res if res else err
print(result.decode())
# 再执行另一条命令并获取命令结果
stdin, stdout, stderr = ssh.exec_command('df')
res, err = stdout.read(), stderr.read()
result = res if res else err
print(result.decode())
# 关闭连接
ssh.close()
