RHEL7修改网卡命名规则为eth*

1、修改网卡配置文件

[root@node1 ~]# cd /etc/sysconfig/network-scripts/

[root@node1 network-scripts]# cp ifcfg-eno16777728 ifcfg-eth0

[root@node1 network-scripts]# 

[root@node1 network-scripts]# vi ifcfg-eth0

TYPE=Ethernet

BOOTPROTO=none

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_FAILURE_FATAL=no

NAME=eno16777728修改为eth0

UUID=95c5b7fb-0f6c-4381-b093-7243b962a5ac

DEVICE=eno16777728修改为eth0

ONBOOT=yes

IPADDR=192.168.220.101

PREFIX=24

GATEWAY=192.168.220.2

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

2、修改网卡命名规则

[root@node1  network-scripts]# cd /etc/default

[root@node1 default]# cat grub           在 GRUB_CMDLINE_LINUX项目rfgb quiet前增加net.ifnames=0 biosdevname=0 

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="rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap rhgb quiet"

GRUB_CMDLINE_LINUX="rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap net.ifnames=0 biosdevname=0 rfgb quiet"

GRUB_DISABLE_RECOVERY="true"

3、重新生成grub配置，更新内核参数

[root@node1 default]# grub2-mkconfig -o /boot/grub2/grub.cfg

Generating grub configuration file ...

Found linux image: /boot/vmlinuz-3.10.0-327.el7.x86_64

Found initrd image: /boot/initramfs-3.10.0-327.el7.x86_64.img

Found linux image: /boot/vmlinuz-0-rescue-edcc784febf04e0584af0e6c17b29555

Found initrd image: /boot/initramfs-0-rescue-edcc784febf04e0584af0e6c17b29555.img

done

4、修改网卡规则

[root@node1 default]# cd /etc/udev/rules.d/

[root@node1 rules.d]# vi 70-persistent-ipoib.rules 

#

# ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="32", ATTR{address}=="?*00:02:c9:03:00:31:78:f2", NAME="mlx4_ib3"

修改上述为：ATTR{type}=="1"和NAME="eth0"，即：

# ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="1", ATTR{address}=="?*00:02:c9:03:00:31:78:f2", NAME="eth0"

5、重启主机

[root@node1 rules.d]# reboot
