如何获取网络访问AWS VPC？

Question

我有一个基于 Centos 7 映像构建的非私有 AWS VPC，但是我无法进行 yum 更新。 你能帮我解决一下如何连接到外部网络来进行更新和下载吗？

到目前为止我必须看到的是：

command:  echo $https_proxy
http://172.2x.xx.xx:8080


command: $ sudo yum -y update

私有 VPC 没有 inte.net 访问权限。

要启用 inte.net 访问需要设置inte.net 网关并公开您的 su.net 之一。 该 su.net 中的实例将能够访问 inte.net 并可从 inte.net 访问。

如果您的实例位于私有 su.net 中，并且您希望您的实例具有 inte.net 访问权限，但不能从 inte.net 访问，则必须设置NAT 网关或 NAT 实例。
