使网卡识别为 eth0
方法一。安装系统是,net.ifnames=0 biosdevname=0
方法二。(没有测试):
修改网卡配置文件中的 DEVICE= 参数的关于 eth0
[root@ansheng ~]# cd /etc/sysconfig/network-scripts/
[root@ansheng network-scripts]# vi ifcfg-eno16777728
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777728
UUID=8a3eade8-005c-46df-81f2-6e2598457bac
#DEVICE=eno16777728
DEVICE=eth0
ONBOOT=yes
网卡配置文件名称改为 ifcfg-eth0
[root@ansheng network-scripts]# mv ifcfg-eno16777728 ifcfg-eth0
因 CentOS7 采用 grub2 引导,还需要对 grub2 进行修改,编辑 /etc/default/grub 配置文件,在 GRUB_CMDLINE_LINUX 这个参数后面加入 net.ifnames=0
biosdevname=0
[root@ansheng network-scripts]# vi /etc/default/grub
GRUB_TIMEOUT=
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0"
GRUB_DISABLE_RECOVERY="true"
用 grub2-mkconfig 命令重新生成GRUB配置并更新内核
[root@ansheng network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg

重启系统
reboot
重启完成之后 验证,ip addr 或者 ifconfig
