修改CentOS7网卡名称为传统名称eth0格式

[root@localhost ~]# cd /etc/sysconfig/network-scripts/

[root@localhost network-scripts]# mv ifcfg-eno16777736 ifcfg-eth0

[root@localhost network-scripts]# cat ifcfg-eth0 
DEVICE=eth0
TYPE=Ethernet
BOOTPROTO=static
PEERROUTES=yes
NAME=eth0
ONBOOT=yes
IPADDR=10.0.0.111
NETMASK=255.255.255.0
GATEWAY=10.0.0.2
DNS1=1.1.1.1
DNS2=8.8.8.8

 在grub “GRUB_CMDLINE_LINUX=    “   中加入     “net.ifnames=0 biosdevname=0“”

[root@localhost 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="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto  vconsole.keymap=us rhgb net.ifnames=0 biosdevname=0 quiet"
GRUB_DISABLE_RECOVERY="true"

[root@localhost network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg 
[root@localhost ~]# reboot
[root@localhost ~]# yum -y install net-tools

或者我们可以在安装的时候直接修改参数，光标移动到Install CentOS 7 上然后按TAB键，这样等安装完成网卡名称直接就是eth0
