1. 备份ifcfg-tns33

[root@jboss1 ~]#  cd /etc/sysconfig/network-scripts/
[root@jboss1 network-scripts]#  mv ifcfg-ens33 ifcfg-ens33.bak
[root@jboss1 network-scripts]#  cp  ifcfg-ens33 ifcfg-eth0

2. 修改 ifcfg-eth0

3. 编辑/etc/default/grub并加入" net.ifnames=0 biosdevname=0 "同样是保存并退出  

[root@jboss1 network-scripts]# cat /etc/default/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="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0"
GRUB_DISABLE_RECOVERY="true"

4. 运行命令" grub2-mkconfig -o /boot/grub2/grub.cfg "来重新生成GRUB配置并更新内核参数 

[root@jboss1 network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg
