在CENTOS7/RHEL7修改網卡名稱

一、禁用可預測命名規則

# vim /etc/default/grub

添加兩句： 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 p_w_picpath: /boot/vmlinuz-3.10.0-229.el7.x86_64

Found initrd p_w_picpath: /boot/initramfs-3.10.0-229.el7.x86_64.img

Found linux p_w_picpath: /boot/vmlinuz-0-rescue-a8ecfd39a4014521ae54ccef4ada1c67

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

done

二、修改網卡配置文件

# cd /etc/sysconfig/network-scripts/

# mv ifcfg-enoxxxxxx ifcfg-eth0

三、修改設備對應名稱

# 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"

四、重啓系統便可
