1.删除原来eth0的配置信息，将eth1行的eth1改为eth0
[root@svr5 ~]# vim /etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x1022:0x2000 (vmxnet)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:41:fa:fc", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
[root@svr5 ~]# service network restart
关闭环回接口： [确定]
弹出环回接口： [确定]

5.reboot重启
6.再重启network服务查看是否OK
[root@svr5 ~]# service network restart
