#创建paramiko的SSH客户端
client = paramiko.client.SSHClient()

#设置本地主机无主机的key时的策略，
#这里使用paramiko.client.AutoAddPolicy这个策略，就是自动添加主机名及新主机key到本地的HostKeys对象。
client.set_missing_host_key_policy(paramiko.client.AutoAddPolicy())

#connect连接的方法可参考这里
#connect(hostname, port=22, username=None, password=None, pkey=None, 
#key_filename=None, timeout=None, allow_agent=True, look_for_keys=True, 
#compress=False, sock=None, gss_auth=False, gss_kex=False, gss_deleg_creds=True, 
#gss_host=None, banner_timeout=None, auth_timeout=None, gss_trust_dns=True, passphrase=None)
clent.connect('127.0.0.1',port=22,username='root',password="okokokok")

#exec_command(command, bufsize=-1, timeout=None, get_pty=False, environment=None)¶
stdin,stdout,stderr = client.exec_command('ls -l',timeout=60)

#读取输出结果
result = stdout.read()

#把bite转成string 这样看的输出更整洁
result = result.decode();
#打印结果
print(result)
#关闭ssh连接
client.close()
