How Linux configures multiple IP addresses

Windows system to implement a single NIC to bind multiple IP is very easy to do! However, Linxu system can also be a single NIC binding multiple IP can be implemented? If implemented, is it difficult to operate?

Recent WHIM research pull down! The finishing configuration process is as follows:

Configuration steps:

1, run ifconfig add a ip:192.168.10.22

Command format:: Ifconfig+eth0:x + ip+netmask (subnet mask)

Ifconfig eth0:0 192.168.10.22 netmask 255.255.255.0

Note: If you want to add more, X plus 1 is OK, can support up to 255.

2, in the #cet/sysconfig/network-scripts directory to establish a corresponding eth0:0 directory and modify the relevant data can be.

Here we can use the CP command to do this operation

CP Ifcfg-eth0 ifcfg-eth0:0

Modify the device name, and the IP corresponds to it. Here is a configuration file that I have modified, which I can refer to, red as the modified part.

device=eth0:0

Bootproto=static
broadcast=192.168.1.255
Hwaddr=00:00:12:62:45:16
ipaddr=192.168.1.22
netmask=255.255.255.0
network=192.168.1.0
Onboot=yes
Type=ethernet
