centos 7 網卡名稱更改

標籤：centos7網卡名稱更改

Centos7安裝完成後網卡名稱預設為enoXXX,非常熟悉的ethX沒有了,總是感覺怪怪的。如果迷你安裝找不到ifconfig命令，請安裝net-tools軟體包.更改步驟如下：

1. [[email protected] ~]#vi /etc/sysconfig/network-scripts/ifcfg-enoXXX

   HWADDR=00:0C:29:AF:BF:18
   TYPE=Ethernet
   BOOTPROTO=dhcp
   DEFROUTE=yes
   PEERDNS=yes
   PEERROUTES=yes
   NAME=enoXXX                   //此處將enoXXX更改為ethX
   UUID=17cdd976-0b81-4286-80cf-185ec95f5ae8
   ONBOOT=no                    //此處將no更改為yes      

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

    [[email protected] ~]#mv ifcfg-enoXXX ifcfg-eth0

3. [[email protected] ~]# 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="vconsole.keymap=us crashkernel=auto  vconsole.font=latarcyrheb-sun16 net.ifnames=0 biosdevname=0 rhgb quiet"
   GRUB_DISABLE_RECOVERY="true"   //委任標記為紅色的兩個參數

4. [[email protected] ~]# grub2-mkconfig -o /boot/grub2/grub     // 執行此命令，重新載入下grub配置

5. [[email protected] ~]# reboot

   重啟作業系統，Centos7的網卡名稱就更改完成了。
