Spremenite ime NIC v eth0 na CentOS7.

Oznaka: CentOS7, eth0, network interface,

Po namestitvi CentOS7 ime NIC v prejšnjih različicah CentOS-a postane enp0s3 namesto eth0. Prednost imenovanja eth0 je, da ime NIC ostane po spremembi NIC nespremenjeno. Strojno opremo lahko zamenjate neposredno, ne da bi preimenovali. Prednosti nove sheme poimenovanja se samodejno določijo na podlagi informacije o strojni opremi, topologiji in lokaciji.

Če želimo spremeniti način poimenovanja NIC v eth0, lahko storimo naslednje.
Vnesite imenik konfiguracijskih datotek NIC in prilagodite ime NIC.
[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# mv ifcfg-enp0s3 ifcfg-eth0
Prilagodite konfiguracijske informacije omrežne kartice, spremenite NAME=eth0 in spremenite DEVICE=eth0 na naslednji način:
[root@localhost network-scripts]# cat 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=eth0
UUID=1a3d4251-a3dc-ea48-6e77-234evb23d9476
DEVICE=eth0
ONBOOT=yes
DNS1=8.8.8.8
IPADDR=192.168.0.100
PREFIX=24
GATEWAY=192.168.0.1
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_PRIVACY=no
Spremenite datoteko grub

V vrstico GRUB_CMDLINE_LINUX dodajte net.ifnames=0 biosdevname=0, ločene s presledki, položaj vstavljanja pa je poljuben. Različni stroji so lahko nekoliko različni.
[root@localhost network-scripts]# cat /etc/sysconfig/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="crashkernel=128M rhgb net.ifnames=0 biosdevname=0 quiet"
GRUB_DISABLE_RECOVERY="true"
Obnovite zagonski meni grub
[root@localhost network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg
