[root@master network-scripts]# mv ifcfg-ens33 ifcfg-eno  (重命名你想改的网卡名称)

[root@master network-scripts]#ip addr    (查看MAC地址)

 

[root@master network-scripts]# vi ifcfg-eno  (修改配置文件里面name和device)

TYPE=Ethernet

BOOTPROTO=dhcp

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

IPV6_FAILURE_FATAL=no

IPV6_ADDR_GEN_MODE=stable-privacy

NAME=eno

UUID=9356eadc-9efe-423d-967e-ff01f5971571

HWADDR=00:0c:29:d3:a7:23      ####注意加上HWADDR，指定对应地址

DEVICE=eno

ONBOOT=yes

 

redhat7开始就得用使用下面命令，redhat 6可以忽略

[root@master network-scripts]# vi /etc/default/grub   （禁用该可预测命名规则）

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=rootvg/root rd.lvm.lv=rootvg/swap rhgb quiet net.ifnames=0 biosdevname=0"

GRUB_DISABLE_RECOVERY="true"

 

如果你想要控制其设备名，而不是让内核以它自己的方式命名，创建,/etc/udev/rules.d/XXX-net.rules规则是必要的！

[root@master network-scripts]# vi /etc/udev/rules.d/70-persistent-net.rules

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:d3:a7:23", ATTR{type}=="1", KERNEL=="eno*", NAME="eno"

 

[root@master network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg  (重新生成GRUB配置并更新内核参数)

 

重启系统验证

[root@master ~]# ifconfig
