I have a CentOS 7 Minimal VirtualBox VM that I would like to set a static IP address on. I want to assign the static IP address via a Bash script within the VM (so not using the VirtualBox network interface).

How can this be done?

So far I've tried editing the file : /etc/sysconfig/network-scripts/ifcfg-enp0s8, and putting the below in it (per this question: https://superuser.com/a/365088).


But then the network adaptor doesn't restart (service network restart), which after a considerable amount of restarts/resets/trial, and error, and copious googling, it seems like it could be dozens of different things.

ip a lists two devices:

  • lo
  • enp0s8

I also have a ifcfg-enp0s3 config file in the sysconfig dir (not sure why).

So, what's a nice, simple, predictable, reliable way of setting a static IP address in CentOS 7 Minimal?

    The answer you linked to is correct. – Ramhound Sep 9 '17 at 19:12

  • @Ramhound - That may be the "correct" answer, but I'm afraid it's not a working answer. Sure, if I do ip a it reports that enp0s8 is on my new, desired IP address, and I can ping that address from the client itself, but the host machine can't access it. And as noted above, in this configuration, service network restart returns FAILED, although I've just got rid of that by simply deleting the ifcfg-enps03 file. I still can't externally connect to the client despite being able to on the old address before the change. (And firewalld is stopped). – linux_confusion Sep 9 '17 at 21:35
  • Neither the answer linked nor RHEL Documentation has quoted values. Did you try your configuration without quotes? – sebasth Sep 10 '17 at 6:57
  • @sebasth - the file that already exists (and thus shipped with CentOS) has quote marks. However I've tried both with and without and they make no difference. – linux_confusion Sep 10 '17 at 8:34

Try following:


I believe your problem is primary in the missing NM_CONTROLLED=no. Except of network restart you may try to set it UP with

ifup enp0s8

You may also need to specify GATEWAY=
