前言:
眼前你们对“centos7修改eth0”都比较珍视,同学们都需要知道一些“centos7修改eth0”的相关资讯。那么小编在网络上网罗了一些关于“centos7修改eth0””的相关资讯,希望各位老铁们能喜欢,咱们快快来了解一下吧!本文档介绍更改 RHEL7 或者 CentOS 7 的网卡名称的方法,按照以下步骤来操作就可以实现。文内含长段代码可复制可往左滑,希望对大家有帮助!
01
一、网卡配置文件名称重命名为eth0
也可以改为其他名称
[root@Jaking11 ~]# ifconfigens33: flags=4163mtu 1500 inet 192.168.10.11 netmask 255.255.255.0 broadcast 192.168.10.255 inet6 fe80::250:56ff:fe29:eae prefixlen 64 scopeid 0x20 ether 00:50:56:29:0e:ae txqueuelen 1000 (Ethernet) RX packets 132 bytes 14492 (14.1 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 115 bytes 13105 (12.7 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0lo: flags=73mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 140 bytes 11204 (10.9 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 140 bytes 11204 (10.9 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0[root@Jaking11 ~]#[root@Jaking11 ~]# cd /etc/sysconfig/network-scripts/[root@Jaking11 network-scripts]# lsifcfg-ens33 ifdown-ppp ifup-eth ifup-sitifcfg-lo ifdown-routes ifup-ippp ifup-Teamifdown ifdown-sit ifup-ipv6 ifup-TeamPortifdown-bnep ifdown-Team ifup-isdn ifup-tunnelifdown-eth ifdown-TeamPort ifup-plip ifup-wirelessifdown-ippp ifdown-tunnel ifup-plusb init.ipv6-globalifdown-ipv6 ifup ifup-post network-functionsifdown-isdn ifup-aliases ifup-ppp network-functions-ipv6ifdown-post ifup-bnep ifup-routes[root@Jaking11 network-scripts]# mv ifcfg-ens33 ifcfg-eth0[root@Jaking11 network-scripts]# vim ifcfg-eth0TYPE=EthernetPROXY_METHOD=noneBROWSER_ONLY=noBOOTPROTO=staticDEFROUTE=yesIPV4_FAILURE_FATAL=noNAME=eth0DEVICE=eth0ONBOOT=yesIPADDR=192.168.10.11GATEWAY=192.168.10.2NETMASK=255.255.255.0

二、禁用网卡命名规则
此功能通过
/etc/default/grub
<以上代码可复制粘贴,可往左滑>
文件来控制,要禁用此功能,在文件中加入
"net.ifnames=0 biosdevname=0"
<以上代码可复制粘贴,可往左滑>
即可
[root@Jaking11 network-scripts]# vim /etc/default/grubGRUB_TIMEOUT=5GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"GRUB_DEFAULT=savedGRUB_DISABLE_SUBMENU=trueGRUB_TERMINAL_OUTPUT="console"GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0"GRUB_DISABLE_RECOVERY="true"
<以上代码可复制粘贴,可往左滑>
03
三、添加udev网卡规则
在/etc/udev/rules.d目录中创建一个网卡规则70-persistent-net.rules文件,在文件中写入以下参数:
SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="需要修改名称的网卡MAC地址",ATTR{type}=="1" ,KERNEL=="eth*",NAME="eth0"
<以上代码可复制粘贴,可往左滑>
参考配置:
[root@Jaking11 rules.d]# vim 70-persistent-net.rulesSUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:50:56:29:0e:ae",ATTR{type}=="1" ,KERNEL=="eth*",NAME="eth0"
<以上代码可复制粘贴,可往左滑>
执行grub2-mkconfig -o /boot/grub2/grub.cfg命令生成更新grub配置参数
[root@Jaking11 rules.d]# grub2-mkconfig -o /boot/grub2/grub.cfgGenerating grub configuration file ...Found linux image: /boot/vmlinuz-3.10.0-957.el7.x86_64Found initrd image: /boot/initramfs-3.10.0-957.el7.x86_64.imgFound linux image: /boot/vmlinuz-0-rescue-fe49b659ccb940fa8d260a5897c0b08aFound initrd image: /boot/initramfs-0-rescue-fe49b659ccb940fa8d260a5897c0b08a.imgdone
<以上代码可复制粘贴,可往左滑>
重启Linux系统后验证网卡名称是否更改成功
[root@Jaking11 ~]# ifconfigeth0: flags=4163mtu 1500 inet 192.168.10.11 netmask 255.255.255.0 broadcast 192.168.10.255 inet6 fe80::250:56ff:fe29:eae prefixlen 64 scopeid 0x20 ether 00:50:56:29:0e:ae txqueuelen 1000 (Ethernet) RX packets 86 bytes 10889 (10.6 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 95 bytes 10828 (10.5 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0lo: flags=73mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (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

总 结
以上就是更改 RHEL7 或者 CentOS 7 的网卡名称的方法,最后看到 eth0 说明网卡名称更改成功!
