Record that FreeBSD, Debian, and CentOS are bound to multiple IP addresses-Linux Enterprise applications-Linux server applications. For more information, see the following. 1. FreeBSD:

Configure/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"

Note that the interface is the name of the NIC device.

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

Another IP Address

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

Bind another IP, create another file, ifcfg-eth0

DEVICE = eth0 // whether it is eth0, indicating that this IP address is bound to 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
