CentOS 6.5 安装系统后添加网卡

1、查看网卡信息

1cat /etc/udev/rules.d/70-persistent-net.rules 
2
3
4# This file was automatically generated by the /lib/udev/write_net_rules
5# program, run by the persistent-net-generator.rules rules file.
6#
7# You can modify it, as long as you keep each rule on a single
8# line, and change only the value of the NAME= key.
9
10# PCI device 0x15ad:0x07b0 (vmxnet3)
11SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:56:9e:1d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
12
13# PCI device 0x15ad:0x07b0 (vmxnet3)
14SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:56:9e:27", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

2、复制第一个网卡的信息

1cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1
2
3#修改 DEVICE:eth0 -> DEVICE:eth1
4#修改 HWADDR:00:0c:29:56:9e:1d -> HWADDR:00:0c:29:56:9e:27
5#修改IP信息

3、重启网络

service network restart

完毕
