To restart the network adapter use the following command: service network restart. You may have to restart the network adapter or the machine.
#CENTOS 7 STATIC IP NOT WORKING MAC#
HWADDR=”WHATEVER IS YOUR COMPUTER’S MAC ADDRESS” Here is an example of the file using 192.168.1.2 as the static IP address.
#CENTOS 7 STATIC IP NOT WORKING INSTALL#
Nano will need to be installed using the command: yum install nano Once installed, to use nano to edit the file type: nano /etc/sysconfig/network-scripts/ifcfg-enp0s3 If you are newer to Linux this editor has less of a learning curve than vi. To use this option, type the following command in the prompt: vi /etc/sysconfig/network-scripts/ifcfg-enp0s3

If you are familiar with using the vi editor you can also modify the ifcf-eth0 file using vi. For example, if the real address of is 192.168.1.200 and you want to restrict access to it, then simply make the following changes to the hosts file on the computer that you want to. If you wish to set a static IP address you can do so by selecting the IP version and editing it. The list is not restricted by size, and you can even employ this method to block access to certain websites by simply re-pointing all requests to visit a known website to a different IP address. To allow the adapter to fire up at startup, use the spacebar to place an “x” in the Automatically connect option. Using the arrow keys, select Edit and press Enter. Your network adapter should be listed, for example enp0s3 is what is listed on my computer. With Edit a Connection selected, press Enter. If you plan on configuring the network adapter using the nmtui utility open a terminal and enter the command nmtui A utility application opens within the terminal that will allow you to configure the network adapters. Another option is to use the nmtui utility to edit the network adapter. One option is to use the vi editor or nano to configure ifcfg-enp0s3. With the minimal installation of CentOS there are not many options available to configure the network adapter. The configuration file for the network adapter should be located at /etc/sysconfig/network-scripts/ifcfg-enp0s3. To view a list of your network adapters use the command ip addr.

The default adapter ens33 is set for dhcp. In this lesson I will set a static IP address for the network adapter. To make this work, I used the nmtui tool and created a new ethernet adapter on my CentOS 8 VM of type Bridge, using the same static IP number I gave to the VM (borrowed from VEA VMnet8). In order to set the network adapter and get get CentOS to communicate on the network the Ethernet adapter will need to be configured.
