CentOS 7.2更改网卡名称

添加net.ifnames=0 biosdevname=0

[root@localhost ~]# vi /etc/sysconfig/grub 
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="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap net.ifnames=0 biosdevname=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
[root@localhost ~]#

更新GRUB、内核配置

[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg

[root@localhost ~]#

添加设备规则配置文件

修改/etc/udev/rules.d/70-persistent-net.rules，没有该文件则新建文件

内容如下　

[root@localhost ~]# cat /etc/udev/rules.d/70-persistent-net.rules
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:a3:b1:5c", ATTR{type}=="1", KERNEL=="eth*", NAME="eno16"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:a3:b1:8e", ATTR{type}=="1", KERNEL=="eth*", NAME="eno10"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:a3:b1:66", ATTR{type}=="1", KERNEL=="eth*", NAME="eno33"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:a3:b1:70", ATTR{type}=="1", KERNEL=="eth*", NAME="eno50"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:a3:b1:7a", ATTR{type}=="1", KERNEL=="eth*", NAME="eno67"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:a3:b1:84", ATTR{type}=="1", KERNEL=="eth*", NAME="eno83"
[root@localhost ~]#

注意MAC地址与NAME相匹配（可以用ip addr查看）

重启

[root@localhost ~]# reboot
