As such, time to to configure static IP address via command line.

After reading this post, you will be able to configure CentOS with a Static IP using the nmcli command line utility. I’ve also provided links to alternative methods:

In my case, I want to set a static IP on eth0. But first, I want to go ahead and change it to an address outside of my DHCP scope. Here’s how to change ip address using nmcli:

sudo nmcli connection modify eth0 IPv4.address
