美国服务器CentOS 7系统下修改默认网卡名为eth0的方法


raksmart的好朋友们,大家好,今天raksmart给大家说一下我们的美国服务器centos7系统下怎么修改默认的网卡名称的方法,大家有需要的可以借鉴一下。

修改网卡配置文件中的 DEVICE= 参数的关于 eth0 

[[email protected] ~]# cd /etc/sysconfig/network-scripts/

[[email protected] network-scripts]# vi ifcfg-eno16777728

TYPE=Ethernet

BOOTPROTO=dhcp

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

IPV6_FAILURE_FATAL=no

NAME=eno16777728

UUID=8a3eade8-005c-46df-81f2-6e2598457bac

#DEVICE=eno16777728

DEVICE=eth0

ONBOOT=yes

网卡配置文件名称改为 ifcfg-eth0

[[email protected] network-scripts]# mv ifcfg-eno16777728 ifcfg-eth0

因raksmart美国服务器 CentOS7 采用 grub2 引导,还需要对 grub2 进行修改,编辑 /etc/default/grub 配置文件,在 GRUB_CMDLINE_LINUX 这个参数后面加入 net.ifnames=0 biosdevname=0 

[[email protected] network-scripts]# vi /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"

 

 grub2-mkconfig 命令重新生成GRUB配置并更新内核

[[email protected] network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg

done

重启系统

[[email protected] network-scripts]# reboot

重启之后验证网卡名称:

[[email protected] ~]# ifconfig

eth0: flags=4163 mtu 1500

  inet 192.168.56.130 netmask 255.255.255.0 broadcast 192.168.56.255

  inet6 fe80::20c:29ff:fe6d:d894 prefixlen 64 scopeid 0x20

  ether 00:0c:29:6d:d8:94 txqueuelen 1000 (Ethernet)

  RX packets 27413 bytes 38532163 (36.7 MiB)

  RX errors 0 dropped 0 overruns 0 frame 0

  TX packets 7727 bytes 702194 (685.7 KiB)

  TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

 

lo: flags=73 mtu 65536

  inet 127.0.0.1 netmask 255.0.0.0

  inet6 ::1 prefixlen 128 scopeid 0x10

  loop txqueuelen 0 (Local Loopback)

  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

OK,上面就是修改网卡名称的所有操作,希望对大家有所帮助。
