CentOS 6.2同一張網卡綁兩個IP

cp /etc/sysconfig/network-scripts/ifcfg-em1 /etc/sysconfig/network-scripts/ifcfg-em1:1

vi /etc/sysconfig/network-scripts/ifcfg-em1:1

DEVICE="em1:1"
HWADDR="D4:AE:52:B8:5D:95"
NM_CONTROLLED="no"
ONBOOT="yes"
IPADDR="第二個IP"
NETMASK="255.255.255.0"
GATEWAY="192.168.0.1"
BOOTPROTO="static"
IPV6INIT="no"

ifup ifcfg-em1:1

如發生斷線
用新增的IP連入後啟動原先IP

ifcfg-em1
