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='47.115.1.74', port=22, username='root', password='1111@')

执行命令

stdin, stdout, stderr = ssh.exec_command('touch ttt')

获取命令结果

result = stdout.read()
print(111)
print(result)

关闭连接

ssh.close()
