You could also add a Gateway address as below. Change BOOTPROTO to "static" and set a IP address and network mask as shown below. Change ONBOOT to "yes" if you want interface to be UP on boot. Using the example interface enp0s3 from above, the file to edit is /etc/sysconfig/network-scripts/ifcfg-enp0s3. Leave the other settings as such and restart networking # systemctl restart network Configure static IPĮdit the config file /etc/sysconfig/network-scripts/ifcfg. If you want to configure DHCP on device enp0s3, edit the file ifcfg-enp0s3įor the device to be activated at startup time ste ONBOOT=yes In this directory, each device should have a configuration file named ifcfg.

Advanced configuration options are limited and it does not yet support some device types like ISDN, IPSec to name a few. However you may not want to run NetworkManager service on your server because of various reasons. For example to get a list if all NICs (Ethernet cards): The command line interface can be invoked by the command nmcli. To invoke the text interface just type: # nmtui Using the GUI is pretty straight forward. You can use Network Manager to create, edit and remove interfaces and it can be used to configure Ethernet, WiFi, Mobile, DSL and PPPoE connections. CentOS 7 comes with Network Manager, a service that runs by default and has a graphical, text as well as command line interface.
