11.网络管理4-rhel7修改网卡名

备份eno16777736网卡配置,并复制出一个ifcfg-eth0

[root@rhel7 network-scripts]# cp ifcfg-eno16777736 ifcfg-eno16777736.bak
[root@rhel7 network-scripts]# cp ifcfg-eno16777736 ifcfg-eth0

修改ifcfg-eth0中的NAME和DEVICE为eth0

[root@rhel7 network-scripts]# vim ifcfg-eth0

禁用可预测命名空间属性

[root@rhel7 network-scripts]# vim /etc/default/grub

找到GRUB_CMDLINE_LINUX行，直接到最后添加，net.ifnames=0 biosdevname=0

更新grub配置文件

[root@rhel7 network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg
