How to configure a static IP address on CentOS 7

Question: On CentOS 7, I want to switch from DHCP to static IP address configuration with one of my network interfaces. What is a proper way to assign a static IP address to a network interface permanently on CentOS or RHEL 7?

If you want to set up a static IP address on a network interface in CentOS 7, there are several different ways to do it, varying depending on whether or not you want to use Network Manager for that.

Network Manager is a dynamic network control and configuration system that attempts to keep network devices and connections up and active when they are available). CentOS/RHEL 7 comes with Network Manager service installed and enabled by default.

To verify the status of Network Manager service:

$ systemctl status NetworkManager.service

To check which network interface is managed by Network Manager, run:

$ nmcli dev status

If the output of nmcli shows “connected” for a particular interface (e.g., enp0s3 in the example), it means that the interface is managed by Network Manager. You can easily disable Network Manager for a particular interface, so that you can configure it on your own for a static IP address.

Here are two different ways to assign a static IP address to a network interface on CentOS 7. We will be configuring a network interface named enp0s3.

Configure a Static IP Address without Network Manager
Go to the /etc/sysconfig/network-scripts directory, and locate its configuration file (ifcfg-enp0s3). Create it if not found.

Open the configuration file and edit the following variables:

In the above, “NM_CONTROLLED=no” indicates that this interface will be set up using this configuration file, instead of being managed by Network Manager service. “ONBOOT=yes” tells the system to bring up the interface during boot.

Save changes and restart the network service using the following command:

# systemctl restart network.service
Now verify that the interface has been properly configured:

# ip add

Configure a Static IP Address with Network Manager

If you want to use Network Manager to manage the interface, you can use nmtui (Network Manager Text User Interface) which provides a way to configure Network Manager in a terminal environment.

Before using nmtui, first set “NM_CONTROLLED=yes” in /etc/sysconfig/network-scripts/ifcfg-enp0s3.

Now let’s install nmtui as follows.

# yum install NetworkManager-tui

Then go ahead and edit the Network Manager configuration of enp0s3 interface:

# nmtui edit enp0s3

The following screen will allow us to manually enter the same information that is contained in /etc/sysconfig/network-scripts/ifcfg-enp0s3.

Use the arrow keys to navigate this screen, press Enter to select from a list of values (or fill in the desired values), and finally click OK at the bottom right:

Finally, restart the network service.

# systemctl restart network.service
and you’re ready to go.

Hello,
I better write this in English and help people all around the world to setup their ipv6 ip addresses easy and fast on Online.net dedicated servers with Proxmox v.4.x installed.

Facts:
1- have an online.net dedicated server
2- Installed Proxmox v.4.x onto it.
3- Need to have 2 seperate KVM virtual machines on it. 1 centos with DirectAdmin, and the other one with Debian and virtualmin. Don’t ask why.
4- Both server and KVM servers need to have ipv4 and ipv6 ip addressess.
5- So in total Server will have 3 ipv4 and /56 ipv assigned to it.
*This is important that you have to understand you can not use this tutorial to create ipv6 only KVM instances.
To do this you must first create another bridge let’s say vmbr2 and assing ipv6 to it.
Other way if you follow my tutorial, Online.net will disable your network port for using unauthorized mac address on their switches.

Anyway Let’s go to the tutorial:
1- Grab a server and install default Proxmox v4.x onto it. In my case Dedibox classic 2016 With Xeon-D and 2x250Gb RAID1 SSD and 32Gb ram.
2- Order additional 2 IPv4’s from online.net
3- Make a /56 subnet froum your assigned /48 ipv6 from your console on online.net. Do not forget to grab/copy your DUID for your newly created /56 ipv6 subnet.
4- On Proxmox host create your KVM servers and assign them ipv4 ips as usual.
5- After everything finished. On proxmox host node do these steps

NOTES FOR MUCH KNOWING GEEKS:

1- yes I know I can use pre-up post-down etc,etc… in /etc/network/interfaces
BUT they do not work in my case. Why I don’t know…
2- yes I know I can add static /56 to my vmbr0 using /etc/network/interfaces. Only if IT WORKS 🙂

so don’t be a fool and don’t follow my guide if you know better than me 🙂

NOW THE KVM part:

In your newly created KVM server of Ubuntu 16.04:

AGAIN: This way works for me. Without any problems at all.
Almost ZERO problems for me.
No ipv6 drops etc.

So Although I know there are better ways to do these.
I prefer to make my ipv6 appear on my own adapters like that.

Thats’s all folks.

If you have anything to ask
shoot me an email at shukko at shukko.com address.

Regards and Happy IPV6 for all..
