Add multiple ip addresses to a single Nic in linux

 

1. First, let's check the network configuration in the system.

Command: ifconfig

2. in linux, the NIC is called eth0, eth1, eth2...... all the NIC configuration files are stored in/etc/sysconfig/network-script. The file name is named after ifcfg-eth0, ifcfg-eth1, ifcfg-eth2. A Nic corresponds to a configuration file. What should we do if we want to configure two IP addresses for eth0?

(1) Go to the NIC configuration file directory:

Cd/etc/sysconfig/network-scripts/

View your Nic configurations:

(2) run the following command to configure a virtual Nic device:

Vi ifcfg-eth0: 0 write the commands shown below in your configuration file case sensitive

Before editing, enter edit mode and press I.

After editing, save the command: (: wq) and exit and save

(3) restart the network configuration to take effect:

Service network restart

In this case, OK. Check the two ip addresses.
