在CENTOS7/RHEL7修改网卡名称

1、禁用可预测命名规则
# vim /etc/default/grub
添加两句： net.ifnames=0 biosdevname=0

GRUB_TIMEOUT=5
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap net.ifnames=0 biosdevname=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.10.0-229.el7.x86_64
Found initrd image: /boot/initramfs-3.10.0-229.el7.x86_64.img

Found initrd image: /boot/initramfs-0-rescue-a8ecfd39a4014521ae54ccef4ada1c67.img
done

2、修改网卡配置文件

# cd /etc/sysconfig/network-scripts/
# mv ifcfg-enoxxxxxx ifcfg-eth0

3、修改设备对应名称
# vim /etc/udev/rules.d/70-persistent-ipoib.rules
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:e0:17:54", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

4、重启系统即可
