How to add a secondary or extra IP in CentOS 7 using nmtui

nmtui (Network Manager Text user interface) is a command line program available in RHEL/CentOS 7 to configure IP address. This is a text based UI which allows you to add IP addresses to your server's network interfaces.

To install nmtui, run

yum install NetworkManager-tui -y

If it wasn't already installed you will need to start the NetworkManager by running:

[root@localhost ~]# systemctl start NetworkManager

The simply run command nmtui to open the user interface:

[root@localhost ~]# nmtui

 

nmtui

hit enter under "Edit a connection":

nmtio 1

Select the desired connection, move using the arrows or tab to edit and hit enter:

nmtui

Now, say we want to add IP 10.10.10.18 to the eth0 interface, we move down to IPv4 CONFIGURATION, right under Addresses we go to <Add...> then hit enter and simply enter the desired IP address:

nmtio

We then go all the way down and hit enter on OK:

nmtui

We can then go back and then Quit:

Once we're back in the linux shell we simply restart the network interface by running:

systemctl restart network
