CentOS7更改网卡名为eth0 





设置网卡1：
> /etc/sysconfig/network-scripts/ifcfg-ens33
echo TYPE=Ethernet >> /etc/sysconfig/network-scripts/ifcfg-ens33
echo BOOTPROTO=none >> /etc/sysconfig/network-scripts/ifcfg-ens33
echo NAME=eth0 >> /etc/sysconfig/network-scripts/ifcfg-ens33
echo DEVICE=eth0 >> /etc/sysconfig/network-scripts/ifcfg-ens33
echo ONBOOT=yes >> /etc/sysconfig/network-scripts/ifcfg-ens33
echo IPADDR=192.168.2.141 >> /etc/sysconfig/network-scripts/ifcfg-ens33
echo PREFIX=24 >> /etc/sysconfig/network-scripts/ifcfg-ens33
echo \#GATEWAY=192.168.2.1 >> /etc/sysconfig/network-scripts/ifcfg-ens33
echo \#DNS1=114.114.114.114 >> /etc/sysconfig/network-scripts/ifcfg-ens33
mac=`ifconfig ens33|grep ether|awk '{print $2}'`
sed -i '/BOOTPROTO/a\HWADDR='$mac'' /etc/sysconfig/network-scripts/ifcfg-ens33
more /etc/sysconfig/network-scripts/ifcfg-ens33
mv /etc/sysconfig/network-scripts/ifcfg-ens33 /etc/sysconfig/network-scripts/ifcfg-eth0
设置网卡2：
> /etc/sysconfig/network-scripts/ifcfg-ens34
echo TYPE=Ethernet >> /etc/sysconfig/network-scripts/ifcfg-ens34
echo BOOTPROTO=none >> /etc/sysconfig/network-scripts/ifcfg-ens34
echo NAME=eth1 >> /etc/sysconfig/network-scripts/ifcfg-ens34
echo DEVICE=eth1 >> /etc/sysconfig/network-scripts/ifcfg-ens34
echo ONBOOT=yes >> /etc/sysconfig/network-scripts/ifcfg-ens34
echo \#IPADDR=192.168.2.139 >> /etc/sysconfig/network-scripts/ifcfg-ens34
echo \#PREFIX=24 >> /etc/sysconfig/network-scripts/ifcfg-ens34
echo \#GATEWAY=192.168.2.1 >> /etc/sysconfig/network-scripts/ifcfg-ens34
echo DNS1=114.114.114.114 >> /etc/sysconfig/network-scripts/ifcfg-ens34
mac=`ifconfig ens34|grep ether|awk '{print $2}'`
sed -i '/BOOTPROTO/a\HWADDR='$mac'' /etc/sysconfig/network-scripts/ifcfg-ens34
more ifcfg-ens34
mv /etc/sysconfig/network-scripts/ifcfg-ens34 /etc/sysconfig/network-scripts/ifcfg-eth1
设置网卡唯一属性并重启生效
sed -i 's/rhgb/net.ifnames=0 biosdevname=0 &/' /etc/default/grub
 grub2-mkconfig -o /boot/grub2/grub.cfg
reboot
