1：修改/etc/udev/rules.d/70-persistent-net.rules
将eth6 改为eth0
注意：只需要修改name即可，不需要修改kernel
[root@itpux ~]# vi /etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:4f:5b:58", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
2：重命名网卡配置文件
需要ifcfg-eth0文件重命名为ifcfg-em1
[root@itpux network-scripts]# mv ifcfg-Auto_eth6 ifcfg-eth0
3：编辑网卡配置文件
1.将名称修改过来
2.并把uuid删除（如果没有就不用）
[root@itpux network-scripts]# vi ifcfg-eth0
HWADDR=00:0C:29:4F:5B:58
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.1.51
PREFIX=24
GATEWAY=192.168.1.51
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME=eth0
#UUID=b1e0320a-6374-468e-aacc-50272cfdf25d
ONBOOT=yes
4：重启服务器，重启之后网卡名称已经修改过来，网络正常
[root@itpux ~]# shutdown -r 0
[root@itpux ~]# ip a
