直接修改/etc/resolv.conf不行。必须要在/etc /sysconfig/network-scripts/ifcfg-eth0里

重新设置服务ip地址比如以下我服务器的配置

DEVICE=eth0
TYPE=Ethernet
UUID=dda8decf-b147-4ad9-805f-3d8e5ef82d9d
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=172.18.5.250        #########服务IP地址
GATEWAY=172.18.5.254     #########默认网关
NETMASK=255.255.255.0    #########子网掩码
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
HWADDR=00:0C:29:E1:56:CD
PEERDNS=yes
PEERROUTES=yes

这样设置后，/etc/resolv.conf里面根本就不需要设置。service network restart

就可以使用yum了
