配置多网卡ip(eth0 and eth1)问题？

来源：互联网发布：js 模块化编程入门编辑：程序博客网时间：2024/05/16 05:59

为做实验的需要，我在一台centos 下（vmnet) 配置多网卡，但是在进去配置eth1的时候，找不到，

[root@niejicai-linux_A ~]# ifconfig

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

[root@niejicai-linux_A network-scripts]# ls

ifcfg-eth0 ifdown-post ifup-eth ifup-routes

ifcfg-lo ifdown-ppp ifup-ippp ifup-sit

[root@niejicai-linux_A network-scripts]#

后面想到了一个办法

直接复制一个网卡的配置文件

[root@niejicai-linux_A network-scripts]# cp ifcfg-eth0 ifcfg-eth1

[root@niejicai-linux_A ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE="eth1"

BOOTPROTO="static"

HWADDR="00:0C:29:13:16:45"

IPV6INIT="yes"

NM_CONTROLLED="yes"

ONBOOT="yes"

TYPE="Ethernet"

UUID="f8badda3-7254-4e7a-9165-442b28f6f9c8"

IPADDR=192.168.10.218

NETMASK=255.255.255.0

GATEWAY=192.168.10.254

PEERDNS=off

DNS1=211.138.245.180

DNS2=202.103.224.68

DNS3=8.8.8.8

然后重启一下设备即可！！
