@H_404_0@方法二：修改rules文件 @H_404_0@1、文件没有的话可以手动创建，后缀是.rules，按照顺序将MAC地址与网卡名称绑定
cat/etc/udev/rules.d/70-persistent-ipoib.rules

@H_404_0@2、修改网卡配置文件，配置DEVICE和NAME，并加入HWADDR
@H_404_0@注：DEVICE、NAME和HWADDR 要和.rules 里面相对应
cat/etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet BOOTPROTO=static DEFROUTE=yes NAME=eth0 #UUID=408326bb-7565-4aa5-b156-c89a0ba839d2 HWADDR=00:0c:29:7a:1e:16 DEVICE=eth0 ONBOOT=yes IPADDR=172.16.18.188 NETMASK=255.255.255.0 GATEWAY=172.16.18.1 DNS=219.141.136.10@H_404_0@3、reboot
