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 eth0iface eth0 inet staticaddress 192.168.1.145
netmask 255.255.255.0
network 192.168.1.0gateway 192.168.1.1
另外一个IP
auto eth0:1iface eth0:1 inet staticaddress 192.168.1.146
netmask 255.255.255.0
network 192.168.1.0gateway 192.168.1.1
3.CentOS:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0ONBOOT=yesHWADDR=00:0C:29:16:39:5FNETMASK=255.255.255.0IPADDR=192.168.1.147GATEWAY=192.168.1.1TYPE=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eth0ONBOOT=yesHWADDR=00:0C:29:16:39:5FNETMASK=255.255.255.0IPADDR=192.168.1.148GATEWAY=192.168.1.1TYPE=Ethernet
