linux环境下修改网卡为eth0

如果没有在安装系统之前传递内核参数将⽹卡名称更改为eth*,则可以在安装系统后修改
编辑vim /etc/default/grub加上这行内容net.ifnames=0 biosdevname=0

vim /etc/default/grub

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=2
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

# update-grub

Ubuntu server还需修改网卡名称为eth0
