在网上找了三个解决方法,第三方法可行! 

1:正确设置ip地址和dns  保证可以平通外网...

修改ip地址: /vi /etc/sysconfig/network-scripts/ifcfg-eth0

--------------------------------------------

BOOTPROTO="static"    

ONBOOT="yes"

IPADDR=192.168.1.111 

  NETMASK=192.168.255.0

GATEWAY=192.168.1.1 

------------------------------------------------

添加DNS: vi /etc/resolv.conf

---------------------------------------------

ameserver 8.8.8.8

---------------------------------------------

2.禁用ipv6地址  (方法很多自己找)

vi  /etc/sysconfig/network

NETWORKING=yes

IPV6INIT=no

3. 更改 repo源.     

/etc/yum.repos.d (自己替换里面的.repo结尾的文件)

我是在虚拟机里出现的这种错误! 我直接删除了 /etc/yum.repos.d 目录下的三个.repo结尾的文件.用正在使用的服务器上的三个.repo文件替换最后可以了....(虚拟机iso文件还是有问题啊!! )
