Linux虚拟机添加网卡

添加完网卡在Linux中用ifconfig看到里面没有eth1网卡

dmesg |  grep eth

e1000 0000:02:00.0: eth0: (PCI:66MHz:32-bit) 00:0c:29:11:30:dd

e1000 0000:02:00.0: eth0: Intel(R) PRO/1000 Network Connection

e1000 0000:02:02.0: eth1: (PCI:66MHz:32-bit) 00:0c:29:11:30:e7

e1000 0000:02:02.0: eth1: Intel(R) PRO/1000 Network Connection



由此命令可以看到网卡驱动已经认到了。

cd /etc/sysconfig/network-scripts/

cp ifcfg-eth0 ifcfg-eth1

vim ifcfg-eth1

DEVICE=eth1

HWADDR=00:0c:29:11:30:e7

TYPE=Ethernet

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=static

IPADDR=172.16.0.1

NETMASK=255.255.255.0

GATEWAY=172.16.0.1

上面加黑的这两个是必须要改的，那个MAC地址是dmesg上面显示出来的地址复制上去

service network restart

Shutting down interface eth0: [ OK ]

Shutting down interface eth1: [ OK ]

Shutting down loopback interface: [ OK ]

Bringing up loopback interface: [ OK ]

Bringing up interface eth0:

Determining IP information for eth0... done.

[ OK ]

Bringing up interface eth1: [ OK ]

这时候eth1就有了

ifconfig
