centos7更改网卡名称为eth0

1查看mac地址，将mac地址写到网卡配置信息中.

cat /sys/class/net/ens33/address

[root@web2 network-scripts]# cat /sys/class/net/ens33/address 
00:0c:29:ba:c4:15

HWADDR=00:0c:29:ba:c4:15写入配置文件中

[root@web ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=none
HWADDR=00:0c:29:6e:27:39
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=10.0.0.31
NETMASK=255.255.255.0
GATEWAY=10.0.0.2
DNS1=114.114.114.114
DNS2=10.0.0.2

在终端执行sed -i ‘s/rhgb/net.ifnames=0 biosdevname=0 &/’ /etc/default/grub

[root@web2 network-scripts]# sed -i 's/rhgb/net.ifnames=0 biosdevname=0 &/' /etc/default/grub 
[root@web2 network-scripts]# cat /etc/default/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="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap net.ifnames=0 biosdevname=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

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

[root@web2 network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg
