Whenever the network the host is connected to changes, the IP address of the VM will change. Now you might be wondering, why not just use a bridged network adapter? Well, you can, but there is one substantial downside. This allows host-to-guest communication but this virtual network has no access to the internet.
#Centos 7 static ip driver#
Bridged – with this mode VirtualBox uses a special driver for the host’s physical network interface to create a virtual network interface for the VM.This gives internet access but applications running on the host can’t make network connections to the VM. NAT – the networking mode of the default network adapter when you create a new VM.

You can read all about the various networking modes here but here’s a quick summary:

#Centos 7 static ip how to#
It turns out that getting this set up is not so trivial, but also, it’s not that hard once you know what VirtualBox provides and how to configure it.

#Centos 7 static ip install#
That means I need Django running on my laptop to be able to access the VM (host-to-guest access) and the VM does need to be able to access the internet (guest-to-internet access) since the Ansible playbooks that are executed against the VM download and install software from the internet. The goal is to have a locally running instance of Airavata that I can connect to when developing the Airavata Django Portal which I’ve been working on. To restart the network adapter use the following command: service network restart.Recently I’ve been working on installing Apache Airavata in a VirtualBox VM running on my laptop using our “standalone” Ansible installation settings. You may have to restart the network adapter or the machine.

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. 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. If you wish to set a static IP address you can do so by selecting the IP version and editing it. 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. In this lesson I will set a static IP address for the network adapter. In order to set the network adapter and get get CentOS to communicate on the network the Ethernet adapter will need to be configured.
