[root@centos4 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:80:19:1b brd ff:ff:ff:ff:ff:ff
    inet 192.168.43.248/24 brd 192.168.43.255 scope global dynamic ens33
       valid_lft 43177sec preferred_lft 43177sec
    inet6 fe80::8441:fe88:6f32:cbf2/64 scope link 
       valid_lft forever preferred_lft forever
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:80:19:25 brd ff:ff:ff:ff:ff:ff
    inet 192.168.43.168/24 brd 192.168.43.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fe80:1925/64 scope link 
       valid_lft forever preferred_lft forever

[root@centos4 network-scripts]# cat ifcfg-eth0
DEVICE=eth0
HWADDR=00:0c:29:80:19:25
IPADDR=192.168.43.168
NETMASK=255.255.255.0
NETWORK=192.168.43.0

主要是HWADDR=00:0c:29:80:19:25这个mac地址与ip a中查询到的需修改网卡ens33的mac地址要一致。
