Redhat 7/CentOS 7 修改網卡名稱 Eno* 成 Eth0

環境
Redhat 7/CentOS 7 (皆測試過)

ROOT only

為求設定不受NetworkManager干擾，故將其服務停止

=CentOS 6=
service NetworkManager stop
chkconfig NetworkManager off

=CentOS 7=
systemctl stop NetworkManager
systemctl disable NetworkManager


啟動network

=CentOS 6=
chkconfig network on
service network restart

=CentOS 7=

chkconfig network on

systemctl start network 

1.開啟grub 設定檔

vi /etc/sysconfig/grub

2.添加指令於GRUB_CMDLINE_LINUX 裡

從

GRUB_CMDLINE_LINUX="rd.lvm.lv=rhel/swap crashkernel=auto rd.lvm.lv=rhel/root rhgb quiet "

增加進於"之前

GRUB_CMDLINE_LINUX="rd.lvm.lv=rhel/swap crashkernel=auto rd.lvm.lv=rhel/root rhgb quiet net.ifnames=0 biosdevname=0"

※這行於CentOS7與Redhat7 不一樣
3.修改ens*的檔名為eth0

cd /etc/sysconfig/network-scripts/    #網路卡設定檔位置

mv ifcfg-ens192 ifcfg-eth0

4.修改eth0裡的name值為eth0

NAME=eth0
DEVICE=eth0

5.將設定載入

grub2-mkconfig -o /boot/grub2/grub.cfg

6.重啟

reboot
