更改 RHEL7 或者 CentOS 7 的网卡名称

此功能通过

/etc/default/grub

文件来控制，要禁用此功能，在文件中加入

"net.ifnames=0  biosdevname=0"

即可

[root@Jaking11 network-scripts]# vim /etc/default/grub  GRUB_TIMEOUT=5GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"GRUB_DEFAULT=savedGRUB_DISABLE_SUBMENU=trueGRUB_TERMINAL_OUTPUT="console"GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0"GRUB_DISABLE_RECOVERY="true"

在/etc/udev/rules.d目录中创建一个网卡规则70-persistent-net.rules文件，在文件中写入以下参数：

SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="需要修改名称的网卡MAC地址",ATTR｛type｝=="1" ,KERNEL=="eth*",NAME="eth0"

参考配置：

[root@Jaking11 rules.d]# vim 70-persistent-net.rulesSUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:50:56:29:0e:ae",ATTR｛type｝=="1" ,KERNEL=="eth*",NAME="eth0"

以上就是更改 RHEL7 或者 CentOS 7 的网卡名称的方法，最后看到 eth0 说明网卡名称更改成功！
