centos minimal网络配置，添加网卡

1、默认centos minimal，网络未启动，通过以下修改

vi  /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
HWADDR=08:00:27:C4:E9:6D
TYPE=Ethernet
UUID=eeba00b3-def9-4359-ba78-51c5ed4e8205
ONBOOT=yes  #修改这里为yes
NM_CONTROLLED=no #修改这里为no
BOOTPROTO=dhcp

然后   service network restart

即可

 

2、通过虚拟机添加了网卡，但是不起效果，

vi /etc/udev/rules.d/70-persistent-net.rules  #可以看到几块网卡

 

# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:c4:e9:6d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:42:e4:29", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
~                                                                                                                                   

然后复制 刚刚添加的网卡mac，如eth1的08:00:27:42:e4:29

cp /etc/sysconfig/network-scripts/ifcfg-eth0  /etc/sysconfig/network-scripts/ifcfg-eth1

vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1 #修改为eth1
HWADDR=08:00:27:42:e4:29 #粘帖刚才复制的eth1的mac
TYPE=Ethernet
UUID=eeba00b3-def9-4359-ba78-51c5ed4e8205
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=dhcp

然后保存 service network restart
