ubuntu 修改网卡名

sudo nano /etc/default/grub

****
找到GRUB_CMDLINE_LINUX=""
改为GRUB_CMDLINE_LINUX=***"net.ifnames=0 biosdevname=0 "*****然后**

sudo grub-mkconfig -o /boot/grub/grub.cfg

重启后，网卡名称变成了eth0和wlan0

重启后没有enth0 无法ping

问题
ifconfig 没有eth0 但 ifconfig -a 有。

解决方法：
是需要本地网卡驱动启动 ifconfig enth0 up

修改 /etc/network/interfaces 加入eth0配置

然后sudo /etc/init.d/networking restart 或在sudo systemclt networing restart
但有错误：
[…] Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code.
See “systemctl status networking.service” and “journalctl -xe” for details

看提示输入 systemctl status networking.service
看状态详细信息问题：Unknown interface etho
要ifconfig看有没有eth0信息sudo ifup eth0 启动网卡
$ifconfig -a eth0 显示IP
sudo ifup eth0
