方式1： 

1）修改/etc/sysconfig/network-scripts/ifcfg-eth0 为 /etc/sysconfig/network-scripts/ifcfg-eth1 

2）配置/etc/sysconfig/network-scripts/ifcfg-eth1 

# 修改为eth1 

DEVICE="eth1" 

BOOTPROTO="static" 

# 硬件地址取自eth1（通过“ifconfig -a”获取） 

HWADDR="00:0C:29:91:42:2C" 

MTU="1500" 

NM_CONTROLLED="yes" 

ONBOOT="yes" 

IPADDR=192.168.152.101 

NETMASK=255.255.255.0 

GATEWAY=192.168.152.2 

3）service network restart 

方式2： 

1）修改/etc/udev/rules.d/70-persistent-net.rules 

拷贝eth1的硬件地址到eth0 

删除eth1信息 

2）配置/etc/sysconfig/network-scripts/ifcfg-eth0 

DEVICE="eth0" 

BOOTPROTO="static" 

HWADDR="00:0C:29:91:42:2C" 

MTU="1500" 

NM_CONTROLLED="yes" 

ONBOOT="yes" 

IPADDR=192.168.152.101 

NETMASK=255.255.255.0 

GATEWAY=192.168.152.2 

3）reboot 

方式3（未测试）： 

1）删除/etc/udev/rules.d/70-persistent-net.rules 

2）配置/etc/sysconfig/network-scripts/ifcfg-eth0 

DEVICE="eth0" 

BOOTPROTO="static" 

HWADDR="00:0C:29:91:42:2C" 

MTU="1500" 

NM_CONTROLLED="yes" 

ONBOOT="yes" 

IPADDR=192.168.152.101 

NETMASK=255.255.255.0 

GATEWAY=192.168.152.2
