1、重命名并修改网卡配置文件，将"NAME"参数更为我们熟悉的“eth*”，这里我将其改为"eth0"
1 [root@localhost ~]# cd /etc/sysconfig/network-scripts/ 2 [root@localhost network-scripts]# mv ifcfg-eno16777736 ifcfg-eth0 3 [root@localhost network-scripts]# vim ifcfg-eth0 4 HWADDR=00:0C:29:BA:53:E3 5 TYPE=Ethernet 6 BOOTPROTO=dhcp 7 DEFROUTE=yes 8 PEERDNS=yes 9 PEERROUTES=yes 10 IPV4_FAILURE_FATAL=no 11 IPV6INIT=yes 12 IPV6_AUTOCONF=yes 13 IPV6_DEFROUTE=yes 14 IPV6_PEERDNS=yes 15 IPV6_PEERROUTES=yes 16 IPV6_FAILURE_FATAL=no 17 NAME=eth0 #修改此参数，和文件名称ifcfg-eth0保持一致 18 UUID=a937a6e4-f70d-4422-b617-ea0b53cab76e 19 ONBOOT=yes
2、修改grub文件/etc/sysconfig/grub，在“GRUB_CMDLINE_LINUX”参数行中添加“net.ifnames=0 biosdevname=0”
1 [root@localhost network-scripts]# vim /etc/sysconfig/grub 2 GRUB_TIMEOUT=5 3 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" 4 GRUB_DEFAULT=saved 5 GRUB_DISABLE_SUBMENU=true 6 GRUB_TERMINAL_OUTPUT="console" 7 GRUB_CMDLINE_LINUX="rd.lvm.lv=rhel/root vconsole.keymap=us vconsole.font=latarcyrheb-sun16 crashkernel=auto net.ifnames=0 biosdevname=0 rhgb quiet" 8 GRUB_DISABLE_RECOVERY="true"
3、重新生成grub配置并更新内核参数:
运行命令:”grub2-mkconfig -o /boot/grub2/grub.cfg“
1 [root@localhost network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfgGenerating grub configuration file ... 2 Found linux image: /boot/vmlinuz-3.10.0-123.el7.x86_64 3 Found initrd image: /boot/initramfs-3.10.0-123.el7.x86_64.img 4 Found linux image: /boot/vmlinuz-0-rescue-e5dec78a32184af9be1ffa5acfa5efbb 5 Found initrd image: /boot/initramfs-0-rescue-e5dec78a32184af9be1ffa5acfa5efbb.img 6 done
4、重启系统后，ifconfig查看：
1 [root@localhost ~]# ifconfig 2 eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 3 ether 00:0c:29:ba:53:e3 txqueuelen 1000 (Ethernet) 4 RX packets 480 bytes 48151 (47.0 KiB) 5 RX errors 0 dropped 0 overruns 0 frame 0 6 TX packets 0 bytes 0 (0.0 B) 7 TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 8 9 eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 10 ether 00:0c:29:ba:53:ed txqueuelen 1000 (Ethernet) 11 RX packets 28067 bytes 1904426 (1.8 MiB) 12 RX errors 0 dropped 0 overruns 0 frame 0 13 TX packets 0 bytes 0 (0.0 B) 14 TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
5、为了双重保险起见建议使用udev规则管理，在”/etc/udev/rules.d“目录中创建一个网卡规则”70-net.rules“,并写入下面的语句:
ACTION=="add",SUBSYSTEM=="net",DRIVERS=="*",ATTR{address}=="00:0c:29:ba:53:e3",ATTR{type}=="1",KERNEL=="eth*",NAME="eth0"
1 [root@localhost ~]# cd /etc/udev/rules.d/ 2 [root@localhost rules.d]# vim 70-net.rules 3 ACTION=="add",SUBSYSTEM=="net",DRIVERS=="*",ATTR{address}=="00:0c:29:ba:53:e3",ATTR{type}=="1",KERNEL=="eth*",NAME="eth0" 4 [root@localhost rules.d]# udevadm trigger
