CONFIGURE CENTOS 7 STATIC IP MOD
nmcli con mod eth1 autoconnect yesĪfter that, restart the ‘eth1’ interface. nmcli con mod eth1 ipv4.dns "1.1.1.1 192.168.10.1"Īnd enable the ‘eth1’ interface to start automatically on the system boot. Now change the IP address and the gateway with the new IP address. The ‘nmcli connection modify’ command to ‘nmcli con mod’ etc.įirstly, we need to change the IPv4 configuration mode on the ‘eth1’ interface to ‘Manual’. Next, we’re going to change the ‘eth1’ with a new static IP address ‘192.168.10.100’ using the nmcli command-line.įor the next commands, we will be using the short version of nmcli command options. nmcli connection show nmcliĪs a result’ we’ve two network interfaces on our CentOS 8 server, the ‘eth0’ with the IP address ‘192.168.122.45’ and ‘eth1’ with the IP address ‘192.168.10.105’. The nmcli is used to create, edit, delete, enable, disable, disable, display the network status on the server.īefore we configure the static IP address, we check all available interfaces on the CentOS 8 server using the nmcli command below. It can be used as a replacement for graphical applications such as “nm-Applet”. With nmcli you can control the NetworkManager and view its status. As known, the nmtui is a TUI (Text User Interface) based application, the nmcli is the command line based application to manage the NetworkManager.
Setup a Static IP Address using Nmcli on CentOS 8Īnother way to configure a static IP address on the CentOS 8 system is to use the ‘nmcli’ program. ifconfig eth1Īnd you will get the ‘eth1’ interface with a new static IP address ‘192.168.10.100’, as we assigned through the nmtui. Now check again the ‘eth1’ interface IP address. Next, we need to restart the network interfaces itself for getting the new static IP address. And the new IP address has been assigned. Once all is complete, choose ‘OK’ and hit the enter button. Now change the IPv4 configuration as you need. To edit the specific interface, you can use the nmtui command as below. You will get two network interfaces ‘ eth0‘ and ‘ eth1‘.Īnd for this guide, we’re going to set up the ‘eth1’ interface with the new static IP address. Next, check all available interfaces on the system using the following commands. The ‘nmtui’ package has been installed on CentOS 8 server. rpm -qa | grep NetworkManagerĮnsure you get the ‘NetworkManager-tui’ package on the list.
The nmtui is a text-based user interface application, can be run on the Terminal shell for managing the NetworkManager.įirst, check the ‘nmtui’ package on the server and make sure it’s installed. Nmtui is a curses-based tui application for interacting with the NetworkManager. And the NetworkManager provided the TUI (Text User Interface) based application that allows you to create and edit the network configuration, its called ‘nmtui’. For the new version CentOS 8, all configuration related networking is managed by the NetworkManager service. On the new version of CentOS 8, there are some major changes related the Networking. Setup a Static IP Address using Nmtui on CentOS 8 And make sure you have the root privileges, the IP address with details gateway, and have basic knowledge about Linux and CentOS command-line.
The goal is to set up the eth1 interface with the following details:įor this guide, you will need the CentOS 8 server with some basic tools such as vim and net-tools installed on it.
I will show you three different ways to set up a static IP address by using nmcli, nmtui and by editing the interface configuration file directly.įor this guide, we will set up a static IP address for the eth1 interface on CentOS 8 server.
