记录一下, 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

DEVICE=eth0                 // 注意还是eth0, 指示此IP绑定到eth0
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
