1、调整网卡名称

[root@web01 ~]# cd /etc/sysconfig/network-scripts/          #<==进入网卡文件目录。

[root@web01 network-scripts]# mv ifcfg-ens192 ifcfg-eth0  #<==进重命名网卡名称。

2、编辑网卡的配置信息

[root@web01 network-scripts]# cat ifcfg-eth0    #<==修改后的结果如下。

TYPE=Ethernet

PROXY_METHOD=none

BROWSER_ONLY=no

BOOTPROTO=static

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_FAILURE_FATAL=no

IPV6_ADDR_GEN_MODE=stable-privacy

NAME=eth0    #<==修改为eth0

UUID=97353b57-69ae-4bec-ba7f-8e3e9efefddf

DEVICE=eth0  #<==修改为eth0

ONBOOT=yes

IPADDR=192.168.1.171

PREFIX=24

GATEWAY=192.168.1.254

DNS1=114.114.114.114

3、修改并生成grub配置

[root@web01 network-scripts]# cat /etc/sysconfig/grub

GRUB_TIMEOUT=5

GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"

GRUB_DEFAULT=saved

GRUB_DISABLE_SUBMENU=true

GRUB_TERMINAL_OUTPUT="console"

GRUB_CMDLINE_LINUX="crashkernel=auto rhgb net.ifnames=0 biosdevname=0 quiet"    #<==×××底纹内容是添加的。

GRUB_DISABLE_RECOVERY="true"

[root@web01 network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg  #<==生成grub启动菜单。

4.验证是否修改结果

[root@web01 network-scripts]# reboot

[root@web01 network-scripts]# ifconfig              #<==再次查看网卡信息
