Linux单网卡绑定多IP

CentOS 网卡IP配置的文件在/etc/sysconfig/network-scripts/下

#cd /etc/sysconfig/network-scripts/
#cp ifcfg-eth0 ifcfg-eth0:1
#vi ifcfg-eth0:1
DEVICE=eth0:1
BOOTPROTO=none
HWADDR=00:19:D1:24:2A:EC
ONBOOT=yes
DHCP_HOSTNAME=www.koven.org
IPADDR=192.168.1.55
NETMASK=255.255.252.0
GATEWAY=192.168.0.1
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes

修改DEVICE和IPADDR这两个地方

启动新配置的IP
#ifup eth0:1
