Python 无法使用boto创建示例VPC。socket.gaierror:[Errno-2]名称或服务未知

我是一个初学者，正在尝试使用boto创建VPC

 [root@localhost orchestration]# cat create-vpc.py
#!/usr/bin/python

import boto.vpc
import pdb


from boto.vpc import VPCConnection

#c = VPCConnection()

c=boto.vpc.connect_to_region('us-east-1')

vpc = c.create_vpc('10.0.12.0/16')
subnet = c.create_subnet(vpc.id, '10.0.12.1/24')

这是我创建VPC的示例脚本。 但是，我收到一个错误“gaierror:[Errno-2]名称或服务未知”

这是完整的回溯

Traceback (most recent call last):
  File "create-vpc.py", line 13, in <module>
    vpc = c.create_vpc('10.0.12.0/16')
  File "/usr/lib/python2.7/site-packages/boto/vpc/__init__.py", line 135, in create_vpc
    return self.get_object('CreateVpc', params, VPC)

    connection = self.proxy_ssl(host, is_secure and 443 or 80)

    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno -2] Name or service not known

另外还有telnet的o/p

[root@localhost orchestration]# telnet yun.local 80
Trying 192.168.240.1...
telnet: connect to address 192.168.240.1: Connection refused

仅供参考

;; ->>HEADER要在boto中创建VPC连接（或任何服务连接对象），您应该使用以下咒语：

import boto.vpc
c = boto.vpc.connect_to_region('us-east-1')  # or whatever

这样，您就可以保证有一个正确初始化的VPCConnection对象指向正确的端点。
您定义了要连接的区域吗？是的，我已经在python脚本本身中定义了该区域。
#/usr/bin/python import boto.ec2 ec2=boto.ec2.connect_to_region（'us-east-1'）打印ec2 ec2.run_实例（'ami-0129cc68'，key_name='/root/IOX_key.pem'，instance_type='t2.micro'，security_groups='sg-08d0ba6d'）
谢谢您的建议，但我仍然收到相同的错误<代码>文件“/usr/lib64/python2.7/socket.py”，第556行，在getaddrinfo（主机、端口、0、SOCK_流）中为res创建连接：socket.gaierro:[Errno-2]名称或服务未知

[root@localhost编排]#cat create-vpc.py#/usr/bin/python import boto.vpc从boto.vpc导入pdb.vpc导入vpc连接#c=vpc连接（）c=boto.vpc.connect_到_地区（'us-east-1'）vpc=c.create_-vpc（'10.0.12.0/16'）子网=c.create_子网（vpc.id，'10.0.12.1/24'）嘿，Garnet！我仍然得到同样的错误。这是我进一步AWS编排活动的拦路虎。你能提出一些建议吗？你得到的错误基本上是一个DNS错误。找不到与服务端点关联的主机。因此，要么它使用了错误的主机名，要么你的DNS工作不正常。你能用你现在的代码更新你原来的问题吗？在注释中很难阅读。您的代码似乎是正确的（尽管您可以删除“from boto.vpc import vpc connection”行，但它没有做任何事情）。创建连接后，是否可以添加“打印（c.host）”？主机的价值是什么？它应该是“ec2.us-east-1.amazonaws.com”。它是？如果是这样，如果您尝试查找该主机，例如“nslookup ec2.us-east-1.amazonaws.com”或“dig ec2.us-east-1.amazonaws.com”，会发生什么情况？是的，c.host的值是ec2.us-east-1.amazonaws.com我已经用nslookup和dig的o/p编辑了这个问题！请建议！！
