Configuration of multiple IP addresses for Ubuntu under single NIC

Delete User Default profile

Due to the default emptying, the configuration file is the system automatically generated user device profile saved under/etc/udev/rule.d/:
# Cp/etc/udev/rule.d/etc/udev/rule.d.bak.0-r
# rm/etc/udev/rule.d/*

Modify the NIC configuration file to add multiple IP configurations

#vim/etc/network/interfaces
Modify or add the following:

Auto Lo iface lo inet loopback auto eth0 iface eth0 inet static address192.168.76.192netmask255.255.255.0Gateway192.168.76.254Auto eth0:0iface eth0:0inet Static Address192.168.76.193netmask255.255.255.0Gateway192.168.76.254Auto eth0:1iface eth0:1inet Static Address192.168.76.194netmask255.255.255.0Gateway192.168.76.254  

Lab environment, I have added three IP addresses

Let the configuration take effect

#/etc/init.d/networking restart

Check effect

#ifconfig

You can see three IP addresses, which indicates that the configuration was successful.
