Ifconfig See if the network card name is eth0, if not, modify the NIC name to Eth0

① editing the network card configuration file

vi/etc/sysconfig/network-scripts/ifcfg-eno16777736

Modify the name and device as Eth0

Name= "Eth0"

Device= "Eth0"

② renaming the NIC configuration file

Mv/etc/sysconfig/network-scripts/ifcfg-eno16777736/etc/sysconfig/network-scripts/ifcfg-eth0

③ Editing Grub Files

Vi/etc/default/grub

Add net.ifnames=0 after RHGB quiet at the end of line 6th 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= "Crashkernel=auto rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap rhgb quiet net.ifnames=0 biosdevname=0"

Grub_disable_recovery= "true"

④ re-establishing the grub file

Grub2-mkconfig-o/boot/grub2/grub.cfg

⑤ do snapshots, shut down, clone.
