Linux-C7系统网卡名字
Linux修改网卡名字
第一步:先ifconfig查看网卡
[root@192.168.20.10 ~]# ifconfig
docker0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 172.17.0.1 netmask 255.255.0.0 broadcast 172.17.255.255
ether 02:42:43:05:65:d4 txqueuelen 0 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.20.10 netmask 255.255.255.0 broadcast 192.168.20.255
inet6 fe80::20c:29ff:fed7:7508 prefixlen 64 scopeid 0x20<link>
ether 00:0c:29:d7:75:08 txqueuelen 1000 (Ethernet)
RX packets 60 bytes 6922 (6.7 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 66 bytes 8883 (8.6 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
第二步:编辑网卡配置更改名字
[root@192.168.20.10 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eth0 #更改这里
UUID=aacfab22-2ec5-4dc6-b378-8011c3a46922
DEVICE=eth0 #更改这里
ONBOOT=yes
IPADDR=192.168.20.10
PREFIX=24
GATEWAY=192.168.20.2
DNS1=223.5.5.5
第三步:修改网卡的名字
[root@192.168.20.10 /etc/sysconfig/network-scripts]# mv ifcfg-ens34 ifcfg-eth0
第四步:修改系统启动项文件
#net.ifnames=0 biosdevname=0
[root@192.168.20.10 ~]# cat > /etc/default/grub<<'EOF'
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="spectre_v2=retpoline rd.lvm.lv=centos/root rd.lvm.lv=centos/swap net.ifnames=0 biosdevname=0 net.ifnames=0 biosdevname=0 rhgb quiet net.ifnames=0 biosdevname=0"
GRUB_DISABLE_RECOVERY="true"
EOF
增加这个
第五步:生成改动的参数
[root@192.168.20.10 ~]# grub2-mkconfig -o /boot/grub2/grub.cfg

运行过程
第六步:重启
[root@192.168.20.10 ~]# reboot
第七步:查看是否生成
