Question

我遇到从iso映像在VM上安装了CentOS 7.5的情况。我的服务器未通过Internet连接。现在，我想从centOS网站更新软件包，但是当我执行 yum update 时，它失败并显示以下错误-

Error- https://mirror.centos.org/centos/7/extras/x86_64/repodata/repomd.xml: [Errno 
14] curl#7 - "Failed to connect to 2a00:1768:1001:48::10: Network is     unreachable"
Trying other mirror.

我在防火墙规则中为mirror.centos.org添加了IP。但是问题是每次我尝试执行nslookup时IP都会不断变化。

[root@763729-mars-oms-docker-registry yum.repos.d]# curl -v https://mirror.centos.org

由于防火墙规则不受我们管理，因此，如果要执行任何更改，我们必须要求云提供商每次执行更改。因此，我们要求对此网址实施动态ACL。但是当他们在我们时区之外工作时，他们需要花一些时间来实施，所以我不得不等待第二天。

但是，有一个用于cent OS镜像存储库的静态IP，我可以引用该静态IP并将其添加一次以解决此问题。或其他建议？

Answer 1

此问题通过在baseurl中添加最近的镜像站点并替换mirror.centos.org得以解决。并在防火墙规则中添加镜像站点IP。
