In this tutorial, we will guide you through the process of installing OpenVZ on NixOS latest version.
OpenVZ is an operating system-level virtualization technology, which allows multiple isolated systems to share a single physical server. It provides a lightweight and efficient way to run multiple virtual machines on a single physical server.
Before we start, make sure you have the following prerequisites:
The first step is to update your NixOS system to make sure you have the latest security and stability patches.
To update your system, run the following command:
sudo nixos-rebuild switch
This command will update your system to the latest version.
To install OpenVZ on NixOS, you need to add the OpenVZ package to your system's configuration file.
Open your NixOS configuration file using your favorite editor by running the following command:
sudo nano /etc/nixos/configuration.nix
In your configuration file, add the following line to the environment.systemPackages section:
environment.systemPackages = with pkgs; [ openvz ];
Save the file and exit your editor.
Now, run the following command to apply the changes to your system:
sudo nixos-rebuild switch
This command will install OpenVZ on your system.
To configure OpenVZ on NixOS, you need to make some changes to your system's configuration file.
Open your configuration file again using your favorite editor by running the following command:
sudo nano /etc/nixos/configuration.nix
In your configuration file, add the following lines to the end of the file:
services.openvz.enable = true;
boot.kernelPackages = pkgs.linuxPackages_5_10;
Save the file and exit your editor.
Now, run the following command to apply the changes to your system:
sudo nixos-rebuild switch
This command will configure OpenVZ on your system.
To create a container in OpenVZ, run the following command:
sudo vzctl create <VEID> --ostemplate <template-name>
Here, <VEID> is the virtual environment ID for the container, and <template-name> is the name of the template you want to use for the container. You can find a list of available templates on the OpenVZ website.
For example, to create a container with ID 101 using the debian-10-x86_64-minimal template, run the following command:
sudo vzctl create 101 --ostemplate debian-10-x86_64-minimal
This command will create a container with the specified ID and template.
To start the container, run the following command:
sudo vzctl start <VEID>
Here, <VEID> is the ID of the container you want to start.
For example, to start the container with ID 101, run the following command:
sudo vzctl start 101
This command will start the specified container.
In this tutorial, you learned how to install OpenVZ on NixOS latest version and how to create and start a container in OpenVZ. With OpenVZ, you can run multiple isolated systems on a single physical server, which can help you optimize your resources and increase your efficiency.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
