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
