The VM will try the second one in case the first nameserver is unreachable.ĥ.) Add the IP and hostname in /etc/ hosts: You can add two or more nameserver entries.

This can be done in /etc/ nf:Īdd or edit the following nameserver entries: nameserverĘ.8.8.8 You do not have to edit the other lines.Īdd the following entries: NETWORKING=yesĤ.) After configuring the IP, we now need to configure DNS. Only the parameters BOOTPROTO, IPADDR, NETMASK, and GATEWAY have to be adjusted (or added if missing). # vim /etc/sysconfig/network-scripts/ifcfg-eth0Ģ.) Make the following changes to ifcg-eth0 in the vim editor: DEVICE='eth0' # cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0.bak Ensure you have the static IP, gateway, and netmask to properly configure the VM:ġ.) From the command line, make a backup of the network card file ifcg-eth0 or ifcg-enp0s3 in /etc/sysconfig/network-scripts/ then proceed with making changes to either file (the file repesent depends on the CentOS release): The Linux way is called prayer-based parsing for a reason: you cannot manipulate text as accurately as objects.įor going further, I assume, that you’ve installed CentOS with the Gnome desktop.To set up a Static IP, please follow the steps below in the VM. I think manipulating objects is a much more efficient, productive and enjoyable way of systems administration, than manipulating and parsing text. I still prefer Windows, especially since PowerShell exists. In Linux, every configuration is just text in text files, which is said to have its advantages. But I’ll elaborate on this in my next article.

I’m planning to install CentOS on an older desktop, because I want to play with its own virtualization technology and I also want bare-metal performance. First of all, I haven’t found a way to activate Enhanced Session Mode and use the connection in full screen. Of course, Hyper-V has its own Virtual Machine Connection, but it doesn’t play well enough with CentOS. Configuring a static IP address isn’t a requirement to run the OS, but it makes a lot easier to connect to the machine through remote desktop. I did it with the intention to explore this enterprise friendly Red Hat derivative and now I’d like to shere my next step. In my last article I explained why and how I installed CentOS in my Hyper-V lab.
