Centos 7-无法下载RPM (尝试与IPV6连接)

Question

我通常是Debian/Ubuntu的人，但我想在CentOS 7上测试领班，但是rpm命令有点问题。我尝试过禁用IPV6

echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6
echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6
sysctl -p

但似乎什么都不起作用？

rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm
Retrieving http://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm
curl: (7) Failed to connect to 2600:3c03::f03c:91ff:fedb:6b1d: Network is unreachable
error: skipping http://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm - transfer failed

Answer 1

(关于不要禁用IPV6的通常警告适用.)

这是相当奇怪的，因为所讨论的IPv6地址位于某些Linode上，而yum.puppetlabs.com是通过Amazon分发的(当时yum.puppetlabs.com是通过IPv6 CloudFront分发的)，并且没有IPv6地址。

$ host yum.puppetlabs.com
yum.puppetlabs.com is an alias for yum.puppet.com.
yum.puppet.com is an alias for d1ge15oq8tiwk1.cloudfront.net.
d1ge15oq8tiwk1.cloudfront.net has address 13.33.115.130
d1ge15oq8tiwk1.cloudfront.net has address 13.33.115.43

当您的系统试图执行此名称解析时，我怀疑本地安装程序给您提供了一个无效的地址。这很可能是/etc/hosts文件中的东西，或者可能是恶意的(或配置不当的) DNS服务器。
