我在使用yum命令和curl时遇到以下错误
-[root @ ip-172-31-47-48 log]＃curl http://www.google.com curl：（7）无法连接到www.google.com端口80：连接超时
-[root @ ip-172-31-47-48 log]＃yum update -y 加载的插件：优先级，update-motd，upgrade-helper 无法检索镜像列表http://repo.us-east-1.amazonaws.com/latest/main/mirror.list，错误为 12：http://repo.us-east-1.amazonaws.com/latest/main/mirror.list上的超时：（28，“连接在5001毫秒后超时”）
其中一个已配置的存储库发生故障（未知）， 并且yum没有足够的缓存数据来继续。在这一点上唯一 yum可以做的安全的事情是失败。有几种方法可以“解决”此问题：
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:
yum-config-manager --disable <repoid>
4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

我正在使用一个具有任何位置的SSH和HTTP入站规则的Sercurity组。没有SG出站规则。我也在使用默认的VPC。
请让我知道注册新域是否与此有关，因为在我注册新域之前这些命令可以正常工作
