ubuntu20.04修改网卡名称为eth*

一 查看当前网卡名称

root@k8s-master-01:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:0c:29:0e:63:73 brd ff:ff:ff:ff:ff:ff
    inet 192.168.174.100/24 brd 192.168.174.255 scope global ens33
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fe0e:6373/64 scope link 
       valid_lft forever preferred_lft forever

二 修改grub文件

root@k8s-master-01:~# cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0

GRUB_TIMEOUT_STYLE=hidden

GRUB_TIMEOUT=0

GRUB_DISTRIBUTOR=lsb_release -i -s 2&gt; /dev/null || echo Debian

GRUB_CMDLINE_LINUX_DEFAULT="maybe-ubiquity"

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"  #修改此项

三 更新grub文件

root@k8s-master-01:~# update-grub
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/init-select.cfg'
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-5.4.0-89-generic
Found initrd image: /boot/initrd.img-5.4.0-89-generic
done

四 重启后验证

root@k8s-master-01:~# reboot
root@k8s-master-01:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:0c:29:0e:63:73 brd ff:ff:ff:ff:ff:ff
    inet 192.168.174.100/24 brd 192.168.174.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fe0e:6373/64 scope link 
       valid_lft forever preferred_lft forever
