网卡回归

cd /etc/NetworkManager/system-connections/
mv ens32.nmconnection eth0.nmconnection   //网卡配置文件改名
vim eth0.nmconnection    //ens32替换成eth0，uuid删掉
vim /etc/default/grub   //改内核参数

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="resume=/dev/mapper/rl-swap rd.lvm.lv=rl/root rd.lvm.lv=rl/swap net.ifnames=0 biosdevname=0"        //net.ifnames=0 biosdevname=0是自己手动添加的
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true

如下
再将网卡配置文件内的网卡名和网卡ID更改为eth0，然后重启网卡即可

grub2-mkconfig  -o /boot/grub2/grub.cfg    //刷新内核参数表 重构菜单
nmcli connection down eth0;nmcli connection up eth0
或者直接nmcli connection reload
