编辑一下配置文件
比如我的配置如下：（采用静态IP）
[root@localhost MarsDiskImage]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:30:18:A1:31:9C
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.2.149
GATEWAY=192.168.2.9
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
