Linux从入门到放弃 网卡配置详解

1. /etc/sysconfig/network-scripts/ifcfg-ens33(网卡名称)

[root@x1 ~]# cd /etc/sysconfig/network-scripts/ ; ls
ifcfg-ens33   ifdown-ippp  ifdown-routes    ifup          ifup-ipv6   ifup-ppp       ifup-tunnel
ifcfg-lo     ifdown-ipv6  ifdown-sit       ifup-aliases  ifup-isdn   ifup-routes    ifup-wireless
ifdown       ifdown-isdn  ifdown-Team      ifup-bnep     ifup-plip   ifup-sit       init.ipv6-global
ifdown-bnep  ifdown-post  ifdown-TeamPort  ifup-eth      ifup-plusb  ifup-Team      network-functions
ifdown-eth   ifdown-ppp   ifdown-tunnel    ifup-ippp     ifup-post   ifup-TeamPort  network-functions-ipv6

2. mv修改网卡名称

mv ifcfg-ens33 ifcfg-eth0

3. 修改网卡配置文件中名称

[root@x1 network-scripts]# vim ifcfg-eth0

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=5ecdf93d-4209-4e02-a428-6703f44ad583
DEVICE=ens33
ONBOOT=yes
IPADDR=10.0.0.200
PREFIX=24
GATEWAY=10.0.0.254
DNS1=10.0.0.254
IPV6_PRIVACY=no

NAME=新网卡名称
DEVICE=新网卡名称

4. 修改系统内核配置文件
   修改 /etc/default/grub 文件中

[root@x1 network-scripts]# vim /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="biosdevname=0 net.ifnames=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

GRUB_CMDLINE_LINUX=“biosdevname=0 net.ifnames=0 rhgb quiet”

5. 使配置文件生效

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

6. 重启系统

		reboot
