(转)FreeBSD, Debian, CentOS一个网卡绑定多个IP

1. FreeBSD:
配置/etc/rc.conf
ifconfig_interface="inet 192.168.1.5 255.255.255.0"
ifconfig_interface_alias0="inet 192.168.1.6 255.255.255.0"
注意interface是网卡设备名.
2. Debian
/etc/network/interfaces
auto eth0
iface eth0 inet static
address 192.168.1.145
netmask 255.255.255.0
network 192.168.1.0
gateway 192.168.1.1
另外一个IP
auto eth0:1
iface eth0:1 inet static
address 192.168.1.146
netmask 255.255.255.0
network 192.168.1.0
gateway 192.168.1.1
3.CentOS:

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

DEVICE=eth0

ONBOOT=yes

HWADDR=00:0C:29:16:39:5F

NETMASK=255.255.255.0

IPADDR=192.168.1.147

GATEWAY=192.168.1.1

TYPE=Ethernet

绑定另外一个IP, 创建另外一个文件, ifcfg-eth0:1

#cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0:x

DEVICE=eth0:1

ONBOOT=yes

HWADDR=00:0C:29:16:39:5F

NETMASK=255.255.255.0

IPADDR=192.168.1.148

GATEWAY=192.168.1.1

TYPE=Ethernet
