注意：这是我在堆栈交换网络上的第一个问题,请怜悯并在需要时提供指导.
我安装了一个CentOS 6.2 KVM客户端,我遇到了让yum工作的问题.这是我第一次使用CentOS,所以我觉得这是一个我错过但却找不到使用谷歌的地方.
这是我的步骤;
>下载CentOS-6.2-x86_64-minimal.iso,启动并执行默认步骤(仅询问键盘,时区,root密码和使用整个硬盘的问题)
>重新启动,登录,ping google.com无济于事
>设置以下设置;
vi /etc/resolv.conf
nameserver 8.8.8.8 nameserver 8.8.4.4
vi / etc / sysconfig / network-scripts / ifcfg-eth0
DEVICE="eth0" HWADDR="52:54:00:42:1B:4A" #NM_CONTROLLED="yes" BOOTPROTO=none ONBOOT="yes" NETMASK=255.255.255.0 IPADDR=192.168.122.151 TYPE=Ethernet
vi / etc / sysconfig / network
NETWORKING=yes NETWORKING_IPV6=no HOSTNAME=server3.example.com GATEWAY=192.168.122.1
>我现在可以ping google.com
ping google.com

>但我不能’yum update’

我的KVM访客也是NAT,因为它令人担忧.
您的系统正在DNS中查找mirrorlist.centos.org的IPv6地址,然后无法连接到该地址.除非您实际拥有IPv6连接,否则应该是
disable IPv6.
