CentOS Minimal Install

ifup eth0
chkconfig iptables off
sestatus

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

这样设置扣，记得重启网卡：
[root@localhost ~]# /etc/init.d/network stop
[root@localhost ~]# /etc/init.d/network start

于是在/etc/rc.d/rc.local文件中加入

ifup eth0

或者

ifconfig eth0 up
eth0就是要激活的网卡，我系统中的是eth0:1,所以用ifup eth0:1
