nat – Yum更新不在CentOS 6.2最小安装上工作

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

我的KVM访客也是NAT,因为它令人担忧.
