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   

[root@ansheng ~]# cd /etc/sysconfig/network-scripts/  

[root@ansheng 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  

[root@ansheng 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   

[root@ansheng 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"  

用 grub2-mkconfig 命令重新生成GRUB配置并更新内核  

[root@ansheng network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg

done  

重启系统  

[root@ansheng network-scripts]# reboot  

重启之后验证网卡名称:  

[root@ansheng ~]# 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。
